Valid on day of printing only © BRE Global Ltd 2012 8 Introduction BREEAM Prisons 2008 1.0 Introduction 1.1 What is BREEAM? BREEAM (Building Research Establishment’s Environmental Assessment Method) is the world’s leading and most widely used environmental assessment method for buildings, with over 115,000 buildings certified and nearly 700,000 registered. It sets the standard for best practice in sustainable design and has become the de facto measure used to describe a building’s environmental performance. Credits are awarded in ten categories according to performance. These credits are then added together to produce a single overall score on a scale of Pass, Good, Very Good, Excellent and Outstanding. The operation of BREEAM is overseen by an independent Sustainability Board, representing a wide cross-section of construction industry stakeholders. Aims of BREEAM: • To mitigate the impacts of buildings on the environment • To enable buildings to be recognised according to their environmental benefits • To provide a credible, environmental label for buildings • To stimulate demand for sustainable buildings Objectives of BREEAM: • To provide market recognition to low environmental impact buildings • To ensure best environmental practice is incorporated in buildings • To set criteria and standards surpassing those required by regulations and challenge the market to provide innovative solutions that minimise the environmental impact of buildings • To raise the awareness of owners, occupants, designers and operators of the benefits of buildings with a reduced impact on the environment • To allow organisations to demonstrate progress towards corporate environmental objectives SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Introduction 9 1.2 Governance and Quality Standards The BRE Global “Sustainability Board” oversees BRE Global’s guides, publications, standards and certification schemes in the area of sustainability and the environment. Current standards and schemes include BREEAM, Environmental Profiles, Responsible Sourcing and ISO 14001. One of the main responsibilities of this Board is to ensure that standards, scheme documents and the way BRE Global operates meet the needs of stakeholders. The Board meets three times a year to review these issues. The Sustainability Board reports to the BRE Global Governing Body, which has an independent overview of all BRE Global's schemes and activities. Specific responsibilities of the Sustainability Board and other Boards include: • advising on the need for new standards, certification schemes and publications, including updates to existing ones • advising BRE Global on relevant legislation and technical matters • promoting certification • advising on issues that may affect the reputation and integrity of BRE Global • approving certification schemes, standards, publications or approvals and reviewing outputs from Expert Groups and Working Groups • ensuring a balanced participation with no single interest predominating • providing comments and guidance, where appropriate, on methods of assessment and testing, to review the progress of assessments and advise on content of certificates, prior to publication; and • reviewing and advising on complaints and appeals as requested. The Board represents a wide cross section of stakeholders from the construction industry including designers, developers, end users, financiers, insurers and regulators. The first independent chairman elected by the members is Bill Gething. Bill is one of the most respected figures in sustainable architecture and is the RIBA President's Sustainability Advisor, Chair of the Institute's Sustainable Futures Committee and a partner of Feilden Clegg Bradley Architects LLP.

Valid on day of printing only © BRE Global Ltd 2012 10 Introduction BREEAM Prisons 2008 ISO 9001 BRE Global has ISO 9001 certification for its BREEAM Buildings schemes and also for the assessment and certification of construction materials under the BREEAM LCA (Life Cycle Analysis) environmental profiles. The certification for the BREEAM schemes covers the operations relating to assessor training, licensing, quality management, and record keeping. UKAS Accreditation Assessors qualified to deliver the BREEAM buildings schemes are also covered under a UKAS accredited competent persons scheme. In addition, the operations relating to the certification of the BREEAM buildings versions and the environmental profiles are also covered under UKAS accredited product certification schemes. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Introduction 11 1.3 BREEAM Credibility Technical Credibility BREEAM is tried and tested, both in terms of its robust technical standards and its commercial delivery, and expert advice (based on scientific evidence) continues to inform almost every issue in BREEAM. In the UK there are over 115,000 buildings certified and over 700,000 homes and buildings currently registered for assessment. BREEAM can be used to assess any building type anywhere in the world. Robust Technical Standards BREEAM has always used objective criteria to recognise good environmental performance: • Issues for assessment are agreed to be significant, and offer worthwhile reductions in environmental impact • Issues must be assessable at the relevant stage in the building’s life • Performance levels are based on scientific evidence wherever possible • Performance levels must exceed demands of law and regulations and encourage innovation • Improvements encouraged by BREEAM are achievable and cost effective Where specific targets cannot be set using hard science or research, sensible practical measures are recommended to minimise environmental impact or enhance the environment of the building and its users. Commercial Credibility Assessments are undertaken by organisations and individuals trained and licensed by BRE Global (Assessors). This ensures: • Competition in the market for assessment services • Engagement with the whole of the industry • Assessors work to the same quality standards (monitored by BRE Global) BRE Global has gained UKAS (United Kingdom Accreditation Service) accreditation for all its BREEAM schemes. This means that its management of BREEAM is monitored and overseen by UKAS. SD5054 issue 4.1 Uncontrolled copy if printed.

This document must be used by non assessors for reference only (in accordance with the Terms and Conditions of use). SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Introduction 13 Understanding the BREEAM Scheme Documents This BREEAM scheme covers ten categories of sustainability • Management • Materials • Health & Wellbeing • Waste • Energy • Land Use and Ecology • Transport • Pollution • Water • Innovation including: Each category is detailed in this Scheme Document and consists of a number of issues (summarised below). Each issue seeks to mitigate the impact of a new or refurbished building on the environment by defining a performance target and assessment criteria that must be met to confirm the target has been achieved. Where a performance target has been achieved the number of available BREEAM credits can be awarded.

The targets represent good or best practice in the field of sustainable design and procurement. The majority of BREEAM issues are tradable, meaning that a design team/client can pick and choose which to comply with in order to build their BREEAM performance score. Several BREEAM issues do SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 14 Introduction BREEAM Prisons 2008 have minimum standards meaning that, to achieve a particular BREEAM rating, a defined number of credits for that issue must be achieved (BREEAM’s minimum standards are outlined in section 3.0 Scoring and Rating). Each BREEAM issue is structured as follows: • Issue Information: Issue ID, issue title, number of credits available for meeting the performance target and whether the issue forms part of BREEAM’s minimum standards. • Aim: Broadly outlines the objective of the issue i.e. the impact it intends to mitigate • Assessment Criteria: outlines the building performance target/benchmark and its criteria. Some issue have Exemplary Level Criteria. Where a building demonstrates that it meets Exemplary Level Criteria an Innovation Credit can be awarded (refer to section 13 Innovation for more detail) • Schedule of Evidence Required: outlines typical examples of the type of information that must be collected from the design team/client by the BREEAM assessor so they can assess if the building complies with the issue criteria. • Additional Information: details relevant definitions of BREEAM terminology and contains information to support the assessment and compliance of the building. The following pages contain an example BREEAM issue. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Introduction 15 Example of a BREEAM Issue Please note: this BREEAM issue has been edited for the purpose of demonstration. Information box appears at the top of each BREEAM issue. Each issue has a unique ID and title. The Aim describes the objective of the issue and the impact that the Assessment Criteria seeks to mitigate. Some BREEAM issues have Exemplary Level Criteria. If the assessed building complies with the Exemplary Level Criteria an additional BREEAM credit can be awarded for Innovation. See section 13 Innovation for further detail. This box indicates the total number of BREEAM credits available. These credits can be awarded if the assessed building complies with the assessment criteria. This box states whether or not minimum standards apply to the BREEAM issue. Section 3.3 of the guidance details the specific minimum standards for each relevant BREEAM issue. For example, one of the two available credits for the Man 2 issue must be achieved to obtain an Excellent BREEAM rating. The Assessment Criteria details the requirements that the assessed building must demonstrate compliance with for the available BREEAM credits to be awarded. Occasionally publications and other standards will be referred to within the Assessment Criteria followed by a reference number. Full references to these publications are provided in section 17 of this document. Each BREEAM issue contains a Compliance Notes table. This table provides additional guidance on the application and interpretation of the Assessment Criteria. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 16 Introduction The Schedule of Evidence Required table describes the types of information that must be provided to the BREEAM assessor as evidence of the assessed building’s compliance with the Assessment Criteria. BREEAM Prisons 2008 The Schedule of Evidence table is split in to two sections. The first details the type(s) of evidence required at the interim design stage of assessment. The second describes the type(s) of evidence required at the final post construction stage of assessment. The numbers in the table correspond to the numbered assessment criteria in the above sections. The Additional Information section contains definitions of terms used in the Assessment Criteria and Compliance Notes section. This section will also contain further information relevant to the issue e.g. assessment guidance and relevant SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only websites © BRE Global Ltd 2012 BREEAM Prisons 2008 Scope 17 2.0 Scope This section of the guidance outlines the scope of this non-domestic BREEAM scheme and the type of buildings that it can be applied to. The following information is provided in this section: • The BREEAM assessment and certification stages • Type of building projects that can be assessed using BREEAM • Type of buildings that can be assessed using this BREEAM scheme Non-domestic BREEAM schemes can be used to assess the environmental impacts of a building in accordance with this scope document in England, Scotland, Wales and Northern Ireland. Assessments using UK BREEAM schemes can also be carried out in the Republic of Ireland, but it must be recognised that BREEAM is tailored to the UK’s construction sector. No concessions are made in the schemes where the Republic of Ireland building standards and design and procurement practices differ from those in the UK. Where the building requiring assessment does not fall within the scope of this non-domestic BREEAM scheme or one of the other BREEAM schemes (domestic or non-domestic) or Code for Sustainable Homes, it can be assessed using the BREEAM Bespoke scheme. Where the building requiring assessment is outside of the UK it can be assessed using the BREEAM International scheme; this includes buildings in the Republic of Ireland where it is not appropriate to use a UK scheme. BREEAM International can be used to assess a single development or BRE Global can assist in creating a BREEAM scheme for a country or region. Further information on the BREEAM Bespoke and BREEAM International schemes is available at www.breeam.org or via the BREEAM helpdesk [email protected] SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 18 Scope BREEAM Prisons 2008 2.1 Stages of assessment This BREEAM scheme can be used to assess the environmental impacts arising as a result of an individual building development (including external site areas) at the following stages: 1. Design Stage (DS) - leading to an Interim BREEAM Certificate 2. Post-Construction Stage (PCS) – leading to a Final BREEAM Certificate Design Stage The DS assessment and subsequent interim BREEAM Certification represents the performance of the building at the design stage of assessment, typically prior to the beginning of operations on site. Certification at this stage does not, therefore, represent the building’s final ‘as built’ BREEAM performance. To complete an assessment at this stage the design must be advanced to the point where the relevant information is available to enable the BREEAM assessor to demonstrate, in a robust manner, the building’s performance against the reporting and evidential criteria of the technical guidance. The interim DS assessment will therefore be completed and certified at the scheme design or detailed design stages. Post-Construction Stage The PCS assessment and subsequent BREEAM Certification represents the final ‘as built’ performance and BREEAM Rating. A final PCS assessment is completed and certified after practical completion of the building works. There are two approaches to assessment at the post-construction stage: 1. A post-construction review of an interim design-stage assessment 2. A post-construction assessment A post-construction review serves to confirm the interim BREEAM rating achieved at the design stage in accordance with the reporting and evidential criteria of the technical guidance. Where a formal interim DS assessment has not been carried out and a BREEAM assessment and rating is required, a full PCS assessment can be conducted. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Scope 19 2.2 Type of projects that can be assessed using BREEAM A BREEAM assessment can be carried out at the above stages for the following types of building project: • New Construction • Major refurbishment to existing buildings • New construction to an existing building i.e. an extension of existing building • A combination of new construction and major refurbishment to an existing building • New construction or major refurbishment, which forms part of a larger mixed use building New construction Construction that results in a new stand alone structure, or extension to an existing structure, which will come into operation/use for the first time upon completion of the works. Major refurbishments to existing buildings Construction that results in the fundamental remodelling or adaptation of existing elements of the building envelope, structure and renewal of key building services. And where, on completion of the works, such remodelling / renewal will materially impact on the performance of the building. The term elements include: a. Structural/building envelope elements including walls (including glazing), roofs (including rooflights) and floors. b. Building services elements including lighting (artificial and daylighting), heating, mechanical ventilation/cooling plant and ductwork, water/drainage systems. For the purposes of this definition works to both A and B above must be taking place for the project to be classed as a major refurbishment. Where only individual elements of the structural/building envelope element (e.g. windows or doors), or individual services elements (e.g. a boiler, heating system or lighting installation) are being replaced, remodelled or upgraded, then, the project should not be classed a major refurbishment (see minor refurbishment guidance below). It should be noted that all major refurbishment projects will reuse the majority of the buildings existing supporting sub and superstructure and it is likely that in many cases the building façade will be retained, albeit with some remediation or renovation. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 20 Scope BREEAM Prisons 2008 Minor refurbishment, remodelling or redecoration This BREEAM Scheme and the requirements it sets are predominantly designed to assess the environmental impacts of buildings arising as a result of new and major refurbishment construction works (as defined above). The requirements are therefore tailored according to the opportunities available to influence a buildings environmental performance when major construction work is undertaken. Unless otherwise stated, this scheme is not intended for the assessment of existing buildings undergoing minor remodelling or redecoration works. Existing building fit out works can be assessed within a number of sector schemes including Offices, Retail, Industrial, Education, Healthcare and Bespoke schemes. If there is uncertainty over the appropriateness of applying BREEAM to existing building works that do not meet BREEAM’s definition of major refurbishment, advice can be sought from and the decision informed by a BREEAM Accredited Professional or BREEAM Assessor. New build extensions to existing buildings BREEAM can be used to assess new build extensions to existing buildings and, where the existing building is undergoing major refurbishment, the new build extension and existing building. When assessing only a new-build extension to an existing building, in some BREEAM issues it is necessary to consider services/facilities within the existing building, where such services/facilities will be integral to the new extension or used by the occupants of the new extension. Assessment guidance is provided in the Compliance Notes table within the specific BREEAM issue for such instances, where relevant. Similar buildings (or units) on the same site It is possible to assess a number of separate but similar buildings, or individual units within a larger building development, within one BREEAM assessor’s report. This is subject to the following conditions: 1. The buildings/units must all be on the same site 2. The buildings/units must be of the same building type e.g. an office, with the same building functions/spaces and fitted out to a similar specification and therefore assessed using the same BREEAM issues 3. Each BREEAM issue must be assessed, and its credits awarded, based on the worst performing building/unit 4. The assessment and assessors report produces a single BREEAM rating covering all buildings/units assessed For the above scenario, a single BREEAM certificate will be issued listing all the buildings/units covered by the single BREEAM assessor’s report. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Scope 21 Where required, a duplicate of the certificate can be produced for the purposes of display in each individual building/unit. Duplicates of certificates are not chargeable provided they are requested by the BREEAM assessor along with the initial certification request to BRE Global. Alternatively, a certificate can be produced specific to each individual building/unit. In such cases an additional charge will be made for each individual certificate requested. In either case the certification criteria must be confirmed by the assessor on the Certificate Request Form submitted with their formal assessment report to BRE Global. If one or more building/unit performs markedly better than another on the same site and the client wishes to recognise this, a separate BREEAM assessment and therefore certificate is required.

High security prison: normally holding category A prisoners 2. Standard secured prison: normally holding category B and/or C prisoners 3. Young offender institution 4. Local prison: receive prisoners directly from court on remand or newly sentenced. 5. Women’s prison: closed prisons only. BREEAM Prisons can be used to assess either of the following building types where they form a part of one of the above types of establishment: • House/segregation block • Multi-faith building • Visitors’ centres • Laundry (standalone) • Workshop • Main stores • Education & Training • Estates building • Gatehouse • A hybrid of two or more of the above • Reception building building types e.g. estates and main stores, • Kitchen (standalone) reception • Sports hall/gymnasium building • Healthcare unit and visitor centre, or day care regimes centre The building functions/areas listed below are covered by the scope of BREEAM Prisons where they form a part of one of the above building types: Prison specific areas • Cells • Comms room • Association/atrium space (in a houseblock) • Worship area/Prayer room • Control room • Command suite • Interview and official visit room • CCTV • Counselling/medical rooms • Gatehouse (front desk area) • Waiting, holding, search, ID check area • Mail room • Open/closed visit areas • Consulting/treatment room • Function/multi-purpose/association room • Care/listener suite • Workshop • Meeting rooms Office/staff areas • Cellular or open plan offices SD5054 issue 4.1 Uncontrolled copy if printed.

Where a proposed building contains a small additional function/area that is not listed above, the building can still be assessed using this scheme. If the assessor has reason to believe that this scheme is not appropriate given the small additional function/area type, BRE Global can be contacted for advice. Unless otherwise indicated, BREEAM Prisons cannot be used to assess any of the above functions/spaces as standalone developments; for example, the Prisons scheme cannot be used to assess and certify a swimming pool or nursery that is not a part of one of the above prison establishments. Such buildings can be assessed using one of the other standard BREEAM schemes or, where appropriate, the BREEAM Bespoke scheme. Other secure building types BREEAM Prisons, or a tailored version of the Prisons scheme, may have the scope to assess secure building types as part of a prison establishment not listed above, e.g. open prisons or juvenile offender institutions. BRE Global can be consulted to determine the appropriateness of such cases. Administrative offices buildings on the prisons estate Where appropriate the BREEAM Offices scheme should be used to assess an administrative office building on the prison estate. If such a building is combined with one or more of the prison building types outlined above, BRE Global should be consulted when determining the most appropriate BREEAM scheme to carry out the assessment. Building does not fit the scope of BREEAM Prisons Building types not covered by the scope of BREEAM Prisons could be assessed using another BREEAM scheme.

Valid on day of printing only © BRE Global Ltd 2012 28 Scoring and Rating BREEAM Prisons 2008 design/project team confirms the following to the BREEAM Assessor (who in turn will determine which of BREEAM’s minimum standards apply1): • That the project meets BREEAM’s refurbishment/fit-out definition (see note 2 below) • The proposed scope of works and budget • That the scope of the works excludes the area/function to which the minimum standard(s) relate(see note 3 below) • The approximate cost of complying with a particular minimum standard and therefore it’s potential for feasibly complying given the projects scope/budget • The environmental impact, if any, of ensuring the existing system/building will comply, when such works fall outside of the projects initial scope. For example; for issue Hea 4, having to replace/upgrade an existing but functioning lighting system that does not require replacement. • The design team demonstrates what feasible measures, if any, they can and will take to meet the aim of the BREEAM issue, if not the criteria. It should be noted that the relevant BREEAM assessment issues, for which there are minimum standards, are still applicable to all refurbishment and fit out projects and must still be assessed for compliance. The above exemption simply means that, if the credit for one of the issues is not feasibly achievable given the scope of the project, it will not prevent the building from achieving a PASS, GOOD or VERY GOOD rating. The above exemption cannot be applied to those refurbishment or fit out projects seeking to achieve an Excellent or Outstanding rating i.e. to achieve the higher rating levels the project must comply with the minimum standards applicable to that rating level (as defined in the table above). 1 The BREEAM Assessor will in turn need to identify the relevant issues to BRE Global, who will then provide an amended Assessment Tool for the specific project. 2 Where the project is part new-build-part-refurbishment this policy can apply to the refurbishment element, provided it complies with the above. However, the new build element of the building must meet the relevant minimum standards. 3 If for example the scope of the refurbishment work includes replacing sanitary fittings, then it would not be appropriate to exempt the project from the minimum standards for BREEAM issue Wat 1 Water Consumption, likewise for other BREEAM issues with minimum standards. Where feasible the project must comply with all, or the relevant minimum standards. The BREEAM Assessor will determine, based on the evidence provided to them by the project/design team, those minimum standards which can justifiably be exempt. Any exemption must be verifiable, in accordance with the above guidance and will be subject to BRE Global’s BREEAM Quality Assurance procedures. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Scoring and Rating 29 3.4 BREEAM credits for innovation Innovation credits provide additional recognition for a building that innovates in the field of sustainable performance, above and beyond the level that is currently recognised and rewarded within standard BREEAM issues. Innovation credits therefore enable clients and design teams to boost their building’s BREEAM performance and in addition, help support the market for new innovative technologies and practices. An additional 1% score can be added to a building’s final BREEAM score for each Innovation credit achieved. The maximum number of Innovation credits that can be awarded for any one building assessed is 10; therefore the maximum available score achieved for ‘innovation’ is 10%. Innovation credits can be awarded regardless of the final BREEAM rating i.e. they are awardable at any BREEAM rating level. There are three different ways in which a building can achieve an Innovation credit (all of which are summarised below and detailed in section 13 Innovation). The first is by meeting exemplary performance criteria for an existing BREEAM issue (table 5 outlines the BREEAM issues with exemplary performance criteria). Table 5 BREEAM issues with exemplary level criteria. Man 2 - Considerate Constructors Hea 1 - Daylighting Hea 14 - Office Space (BREEAM Retail & Industrial Schemes only) Ene 1 - Reduction of CO2 emissions Ene 5 - Low or Zero Carbon Technologies Wat 2 - Water Meter Mat 1 - Materials Specification Mat 5 - Responsible Sourcing of Materials Wst 1 - Construction Site Waste Management The second route is where the client/design team sets a specific BREEAM performance targets/objectives and appoints a BREEAM Accredited Professional (AP) throughout the key project work stages to help deliver a building that meets the performance objectives and target BREEAM rating. The final and third route is where an application is made to BRE Global by the BREEAM Assessor to have a particular building feature, system or process recognised as ‘innovative’.

Does the feature, system or process aim to reduce the building’s impact on one of the following overarching environmental/social issues? • Mineral Resource Depletion • Waste Disposal • Fossil Fuel Depletion • Water Use • Acidification • Deforestation • Climate Change • Urban Sprawl • Nuclear Waste • Reduction of Biodiversity • Stratospheric Ozone Depletion • Noise and Nuisance • Eco-toxicity • Loss of Heritage • Eutrophication • Indoor comfort • Human Toxicity • Health and Safety • Photochemical • Access and Inclusion Ozone Creation (Summer Smog) 2. Can the impact of the feature, system or process be assessed objectively using clearly defined criteria? 3. Can the sustainability benefits of the feature, system or process be demonstrated? 4. Have a draft aim, assessment criteria and information required to demonstrate compliance been developed (in accordance with the Innovation credit application form)? A BREEAM assessor can obtain the Innovation credit application form from the BREEAM Office at BRE Global or via the Assessor’s Extranet. The form details the eligibility criteria listed above and the fee payable for each submitted application for an Innovation credit. Innovation credits cannot be awarded until written approval is received from the BREEAM Office. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Scoring and Rating 33 3.6 How to calculate a building’s rating A BREEAM assessor must determine the BREEAM rating using the BREEAM Assessor’s Spreadsheet Tool and associated calculators. An indication of performance against the BREEAM scheme can also be determined using a BREEAM Pre-Assessment Estimator. The Pre-Assessment Estimators are available from the BREEAM website for each scheme. The process of determining a BREEAM rating is outlined below and in table 6: 1. For each BREEAM section the number of credits awarded must be determined by a BREEAM assessor in accordance with BREEAM’s assessment criteria (detailed in the technical sections of the Scheme Document). 2. The percentage of the credits achieved is calculated for each BREEAM section. 3. The percentage of credits achieved is then multiplied by the corresponding BREEAM section weighting (see note below). This gives the section score. 4. The section scores are then added together to give the overall BREEAM score. The BREEAM score is compared to the benchmarks in table 2 and, provided all minimum standards have been met, the relevant BREEAM rating is achieved. 5. An additional 1% can be added to the final BREEAM score for each Innovation credit achieved (up to a maximum of 10%). Note: Where applicable to the BREEAM scheme (see Scope of the BREEAM Scheme), Fit-Out only assessments do not assess the BREEAM issues under the Land Use & Ecology section. The section weighting for Land Use and Ecology is re-distributed amongst the remaining eight sections. The redistribution is determined based on the relative weighting of the remaining sections, so for example, the Energy section receives a greater proportion of the Land Use and Ecology weighting than the Water section. See Table 3 above for details of the respective section weighting. SD5054 issue 4.1 Uncontrolled copy if printed.

The building must achieve a final BREEAM Score ≥85% 2. The minimum performance standards (table 4) for the Outstanding rating level must have been met 3. Provision of material for the production and publication of a case study (refer to guidance below) on the Outstanding rated building. In addition to the above, the ‘BREEAM Outstanding’ building is required to obtain a BREEAM In Use Certification of Performance within the first three years of the building’s operation and use (with regular reviews in accordance with that scheme) in order to maintain the rating. Where the building is not certified against BREEAM In Use during this period, the Outstanding rating will be downgraded to an Excellent BREEAM rating after the expiry of the three years from issue of the Final BREEAM 2008 (Post Construction) certificate. Production of case study One of the most important aspects of the Outstanding BREEAM rating will be that projects receiving this rating will act as exemplars for the industry. It is therefore a very important aspect of the new rating that a good-quality case study is produced that design teams can refer to. The design team and client will be asked via the certificate request form to agree to provide relevant building/project information to allow BRE Global to produce a case study. This information will be required with the formal post construction stage BREEAM assessor’s report for the assessed building. Subject to approval from the design team/client, BRE Global will publish the case study on either the BREEAM website, Green Book live website and other BRE/BREEAM-related publications (as appropriate). Where information is not provided for the production of a case study, the building will be certified to a BREEAM Excellent rating level. SD5054 issue 4.1 Uncontrolled copy if printed.

Considerate Constructors score No credits can be awarded for the Considerate Constructors Scheme where any of the section scores within the scheme are less than 3, as this represents non compliance with the CCS Code of Considerate Practice. Site monitored by CCS more than once Often a site will be visited by the CCS Monitor more than once. The CCS Certificate will be awarded based on the results of the Monitor’s final visit. At the final stage of the BREEAM assessment the number of BREEAM credits awarded should therefore be based on the final visit and the subsequent Monitor’s report and certified CCS score. At the interim design stage of assessment, where the contractor is not yet appointed, the client must either include within the specification, or commit to including, a requirement for the appointed contractor to comply with one of the above criteria. The assessor must use this information to complete the appropriate checklist. Where the project is using an alternative scheme to the CCS, it is the alternative scheme and its assessment criteria that are assessed against Checklist A2, NOT the project or its contractor. Contractor not yet appointed Alternative scheme Site clearance The scope of this issue applies to the main contractor and their scope of works. If the scope of the main contractor’s works includes demolition and site clearance then this stage of work falls within the scope of the credit criteria. Custodial Buildings For custodial buildings, the National Offender Management Service has developed a scheme called ‘Sympathetic Custodial Construction’ (SCC). This scheme is categorised as an alternative to the Considerate Constructors Scheme, and should therefore be assessed against Checklist A2 where its use is specified.

Valid on day of printing only © BRE Global Ltd 2012 44 Man 3 Construction Site Impacts Site timber BREEAM Prisons 2008 The fourth credit (for responsibly sourced site timber) is not dependent on any of the first three credits being achieved. For the purpose of assessing this issue, site timber is considered to be timber used to facilitate construction, including formwork, site hoardings and other temporary site timber used for the purpose of facilitating construction. It does not cover structural timber and timber used for fit-out items (this is addressed in BREEAM issue Mat 5). Site clearance The scope of this issue applies to the main contractor and their scope of works. If the scope of the main contractor’s works includes demolition and site clearance then this stage of work falls within the scope of the assessment criteria. Schedule of Evidence Required Req. Design Stage All A copy of the relevant section from the main contract specification confirming: • Contractor’s obligations in respect to each item on the checklist • Site timber will be sourced from suppliers capable of providing certification to the level required for the particular tier claimed (see Table 13 Responsible Sourcing Tier Levels and Criteria of BREEAM issue MAT 5) • All timber will come from a ‘legal source’ and is not on the CITES list*. Site records demonstrating monitoring and recording of the following (where relevant): • Site energy/CO2 consumption • Site deliveries • Site water consumption OR A letter from the main contractor confirming: • Procedures for pollution management and mitigation were implemented • Name/job title of individual responsible for monitoring and managing construction site impacts throughout the project. Where the main contract specification is not yet available, a formal letter from the client/developer including: • Completed checklist A3 identifying which items will form part of the main contractor’s obligations. • The policy for sourcing site timber for the project. • Confirmation that the above will be implemented in compliance with BREEAM’s criteria. * Or in the case of Appendix III of the CITES list, it has not been sourced from the country seeking to protect this species as listed in Appendix III.

Copies of the documented procedures used on site for working to best practice pollution management guidelines. A copy of the certification document or Chain of Custody (CoC) certificate(s) for the site timber. Where any non-certified timber is used, written confirmation from the supplier(s) confirming that: • All timber comes from a legal source. • All timber species and sources used in the development are not listed on any of the CITES appendices for endangered or threatened species (Appendix I, II, or III*). BREEAM Prisons 2008 Man 3 Construction Site Impacts 45 Additional Information Relevant definitions CITES (Convention on International Trade in Endangered Species)3 Appendices I and II of the CITES list illustrate species of timber that are protected outright. Appendix III of the CITES list illustrates species that are protected in at least one country. If a timber species used in the development is on Appendix III it can be included as part of the assessment as long as the timber is not obtained from the country(s) seeking to protect this species. Chain of Custody: This is a process used to maintain and document the chronological history of the evidence/path for products from forests to consumers. Wood must be tracked from the certified forest to the finished product. All the steps, from transporting wood from the forest to a sawmill, until it reaches the customer, must maintain adequate inventory control systems that allow for separation and identification of the certified product. Chain-of-custody certification ensures that a facility has procedures in place to track wood from certified forests and avoid confusing it with non certified wood. Chain-of-custody is established and audited according to relevant forest certification systems rules. Pollution BRE4 publishes guidance on construction site dust management, and the Environment Agency5 publishes guidance on water pollution control measures. There are significant statutory criteria in this area under environmental health legislation and the Environmental Protection Act. The Environment Agency and local Environmental Health Officers police these. Energy Energy Management on site has been a key focus for the Construction Confederation6, and they have published specific guidance to help achieve this. Monitoring and reporting at site level are the key factors in raising awareness of the impacts of energy consumption. Whilst total energy is frequently monitored, this information is predominantly used to feedback into the tendering process and is seldom used to seek improvements on the site in question. Targets Targets are requested in the BREEAM criteria to promote the process of setting, monitoring and achieving targets. BREEAM does not set targets, as these are very project specific. For guidance on setting targets, refer to Constructing Excellence’ Construction Industry KPI and Benchmarking (www.constructingexcellence.org.uk/zones/kpizone/default.jsp); this series of documents guides the reader through setting targets for their own projects.

Building Log Book The Building Regulations Part L requires the provision of a ‘Building Log-Book’ to the owner and/or occupier of the building. In addition on completion, the Construction Design and Management Regulations require the Health and Safety file to be passed onto the building user. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Man 4 Building User Guide 49 BREEAM requires an additional ‘Building User Guide’ that contains the necessary details about the everyday operation of the development in a form that is easy for the intended users to understand. Without the provision of adequate information and guidance it is likely that the building will be used inappropriately leading to the dissatisfaction of occupants and wasted resources. For example: Some ventilation and/or lighting systems can be impaired by inappropriate positioning of partitions, office furniture etc. so causing inefficiencies, a lack of comfort and poor performance. The aim of this issue is to ensure that design features are used efficiently and that changes to office space are managed in the most appropriate manner. For example, the design team of a speculative, open plan office, are likely to have considered the need for meeting or cellular space, and may have provided additional riser or duct space to assist future use. The design of the building may require additional or expanded systems to be installed if occupant levels rise above those designed for. This information should be passed on to the personnel making management decisions, so that they are aware of the implications of such decisions on the management of the building.

Valid on day of printing only © BRE Global Ltd 2012 62 Man 12 Life Cycle Costing BREEAM Prisons 2008 Additional Information Relevant definitions Life Cycle Cost analysis: A procurement evaluation technique which determines the total cost of acquisition, operation, maintenance and disposal of the building. The assessor should note that BREEAM places fixed criteria on the time at which the Life Cycle Cost feasibility study should be carried out in order that maximum benefit from undertaking this is achieved. The strategic level analysis (looking at issues such as location and external environment, maintainability and internal environment, etc.) and system level analysis (looking at issues such as foundations, solid or framed wall and floors, types of energy, ventilation, water capacity, communications etc.) should be carried out early in the design process to influence the fundamental decisions taken regarding the building without having an adverse affect on either cost or design programme. It is however important that this is revisited as the design develops to ensure that an optimal solution is retained throughout the procurement process. Real and discounted cost: ISO 156868 defines real cost as the cost expressed as a value at the base date, including estimated changes in price due to forecast changes in efficiency and technology, but excluding general price inflation or deflation. Discounted cost is the resulting cost when the real cost is discounted by the real discount rate, or when the nominal cost is discounted by the nominal discount rate. ISO15686 defines nominal cost as the expected price that will be paid when a cost is due to be paid, including estimated changes in price due to, for example, forecast change in efficiency, inflation or deflation and technology.

All custody cells to be adequately daylit with an average daylight factor of 2% 3. In the internal association/atrium area the following criteria are met: a. Average daylight factor of 5% or more AND b. A uniformity ratio of at least 0.7 or a minimum point daylight factor of 3.5%. 4. The criteria outlined above concerning uniformity ratio, view of sky or room depth criterion are met. Where demonstrating compliance via uniformity ratio or point daylight factor the following minimum criteria apply: a. Multi-storey: A uniformity ratio of at least 0.4 or a minimum point daylight factor of at least 1.2%; (spaces with glazed roofs, such as atria, must achieve a uniformity ratio of at least 0.7 or a minimum point daylight factor of at least 2.1%). b. Single storey: a minimum point daylight factor of at least 1.6%; (spaces with glazed roofs, such as atria, must achieve a uniformity ratio of at least 0.7 or a minimum point daylight factor of at least 2.8%). Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new-build projects. Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to The criteria of this issue apply only to the scope of the assessed building. If this existing buildings scope includes the existing building as well as the new building then the relevant areas within the existing building must be assessed against the criteria of this BREEAM issue. If the assessment covers only the new building, then the areas in the existing building do not need to be assessed. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Percentage of assessed area View of sky requirement Uniformity with rooflights Two-side lit rooms Borrowed light Hea 1 Daylighting 65 Where the compliance requirement specifies that 80% of office or other occupied space floor area must be adequately daylit, it refers to 80% of the total floor area of all the rooms that must be assessed i.e. the compliant area. If for example a development has 6 rooms that must be assessed, each 150m2 (total area 900m2) then 720m2 must comply with the criteria; this is equal to 4.8 rooms. The number of rooms that must comply must always be rounded up; therefore in this example, five rooms must have an average daylight factor of 2% or more (plus meet the other criteria) to achieve the credit. To comply with the view of sky criteria at least 80% of the room that complies with the average daylight factor requirement must meet the view out requirement; i.e. it is permissible for up to 20% of the room not to meet the view of sky requirement and still achieve a compliant room. The room depth criteria cannot be used where the lighting strategy relies on rooflights. In such areas either appropriate software should be used to calculate the uniformity ratio or, in the case of a regular array of rooflights across the whole of the space, ‘Figure 2.36’ (p37) within CIBSE Lighting Guide LG10 can be used to determine the uniformity ratio. For rooms lit by windows on two opposite sides, the maximum room depth that can be satisfactorily daylit is twice the limiting room depth (d) (measured from window wall to window wall; CIBSE Lighting Guide LG10. The reflectance of the imaginary internal wall should be taken as 1. For areas where borrowed light is used, calculations or results from appropriate lighting design software must be provided to demonstrate that such areas meet the BREEAM criteria (if contributing to the percentage of compliant area). Examples of borrowed light include: light shelves, clerestory glazing, sun pipes or internal translucent/transparent partitions (such as those using frosted glass). Schedule of Evidence Required Req.

Point daylight factor: A point daylight factor is the ratio between the illuminance (from daylight) at a specific point on the working plane within a room, expressed as a percentage of the illuminance received on an outdoor unobstructed horizontal plane. This is based on an assumed overcast sky, approximated by the ‘CIE (Commission Internationale de l’Eclairage) overcast sky’. Average daylight factor: The average daylight factor is the average indoor illuminance (from daylight) on the working plane within a room, expressed as a percentage of the simultaneous outdoor illuminance on a horizontal plane under an unobstructed CIE Standard Overcast Sky. Illuminance: The amount of light falling on a surface per unit area, measured in lux. Uniformity: The uniformity is the ratio between the minimum illuminance (from daylight) on the working plane within a room (or minimum daylight factor) and the average illuminance (from daylight) on the same working plan (or average daylight factor). View of sky / no-sky line: Areas of the working plane have a view of sky when they receive direct light from the sky, i.e. when the sky can be seen from working plane height. The no-sky line divides those areas of the working plane, which can receive direct skylight, from those that cannot. Working plane: CIBSE LG10 defines the working plane as the horizontal, vertical or inclined plane in which a visual task lies. The working plane is normally taken as 0.7 m above the floor for offices and 0.85 m for industry. Computer simulation: Software tools that can be used to model more complex room geometries for daylighting.

Assessment Criteria The following demonstrates compliance: 1. The relevant building areas are within 7m distance of a wall with a window or permanent opening providing an adequate view out, where the window/opening is ≥20% of the total inside wall area (refer to Compliance Notes for a definition of relevant building areas and adequate view out). 2. Cells have a view out and the distance between each window and nearest external solid object (i.e. buildings, screens, walls/fences) is ≥10m. Where existing features prevent compliance with this requirement in less than 20% of the cells within the building, the credit can still be awarded. 3. Where present within the assessed building; all patient-occupied spaces (e.g. wards and dayrooms) must be within 7m distance of a window or permanent opening providing a view. Where the room depth is greater than 7m, compliance is only possible where the percentage of window/opening is the same as or greater than the values in table 1.0 of BS 820612. 4.

The view out should ideally be through an external window providing a view of a landscape or buildings (rather than just the sky) at seated eye level (1.2 – 1.3m) in the relevant building areas. A view in to an internal courtyard or atrium will comply provided the distance from the opening to the back wall of the courtyard/atrium is at least 10m (therefore allowing enough distance for the eyes to refocus). The view cannot be an internal view across the room, as this is likely to become obstructed by partitions, filing cabinets etc. Roof lights and high level windows that do not provide an adequate view out do not meet the criteria for this BREEAM issue.

High frequency ballast: High frequency ballasts increase the frequency of the power coming from the grid (50Hz) to a frequency optimising the performance of fluorescent lamps, typically around 30kHz. There are several advantages to running fluorescent lamps at higher frequencies. At 30kHz, the frequency of re-ignition of a fluorescent lamp is too quick to be detected by the human eye, therefore SD5054 issue 4.1 Uncontrolled copy if printed.

Assessment Criteria The following demonstrates compliance: First credit 1. Illuminance (lux) levels in all internal areas of the building are specified in accordance with the CIBSE Code for Lighting 200613. 2. For areas where computer screens are regularly used, the lighting design complies with CIBSE Lighting Guide 714 sections 3.3, 4.6, 4.7, 4.8 and 4.9. This gives recommendations highlighting: a. Limits to the luminance of the luminaires, to avoid screen reflections. (Manufacturers’ data for the luminaires should be sought to confirm this). b. For up-lighting, the recommendations refer to the luminance of the lit ceiling rather than the luminaire; a design team calculation is usually required to demonstrate this. c. Recommendations for direct lighting, ceiling illuminance, and average wall illuminance. 3. Cells must be lit to a maintained illuminance of 200 lux at table-top level. In addition there must be the facility (using, for example, dimming, step switching or separate task and general lighting) for the cell’s occupant to select a lower level of general lighting if required. Second credit 1. Illuminance levels for lighting in all external areas within the construction zone are specified in accordance with CIBSE Lighting Guide 615, ‘The outdoor environment’. 2. In addition, exercise yards should be lit to a maintained illuminance of at least 10 lux. However, if such spaces are, or will be, used as sports facilities they must be lit to a maintained illuminance of 100 lux.

Volatile Organic Compounds VOCs are emitted by a wide array of products numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, glues and adhesives, Urea-formaldehyde foam insulation (UFFI), pressed wood products (hardwood plywood wall panelling, particleboard, fibreboard) and furniture made with these pressed wood products. ‘No’ or ‘low’ VOC paints are available from most standard mainstream paint manufacturers. There ‘ecofriendly’ paints are made from organic plant sources and also powdered milk-based products. The emissions of VOCs from paints and varnishes are regulated by the Directive 2004/42/CE, implemented in the UK by the Volatile Organic Compounds in Paints, Varnishes and Vehicle Refinishing Products Regulation 2005. Products containing high organic solvent content should also be avoided (EU VOC Solvent Directive 1999/13/EC). Exposure risk assessment of any possible release of chemicals from manufactured products and their possible impact on health and the environment generally, is an important requirement of European regulations. The possible impact of a building product on indoor air quality is included in the European Construction Products Directive, 89/106/EEC. The amended Directive, 93/68/EEC provided the criteria for CE Marking of products. Products to be fitted in buildings should not contain any substances regulated by the Dangerous Substances Directive 2004/42/CE, which could cause harm to people by inhalation or contact. Materials containing heavy metals (e.g. antimony, barium, cadmium, lead and mercury) and other toxic elements (e.g. arsenic, chromium and selenium) or regulated biocides (e.g. pentachlorophenol) should be avoided. Various labelling schemes identify products that have been tested and shown to be low emitting and these have been summarised in BRE Digest 46437.

Assessment Criteria The following demonstrates compliance: 1. The heating/cooling system is designed to allow occupant control of zoned areas within all occupied spaces in the building. 2. The zoning allows separate occupant control (within the occupied space) of each perimeter area (i.e. within 7m of each external wall) and the central zone (i.e. over 7m from the external walls). Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new-build projects. Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to Where the existing building falls within the scope of the assessment, then the criteria extend to the occupied spaces of the existing building. If only the new existing buildings extension is being assessed then the criteria apply to the relevant spaces of the new building. Long lag Where long-lag systems are specified, the criteria can be met where they are systems designed to service the base load only and a responsive secondary heating system and controls are provided, zoned in compliance with the above criteria. Distance The distance requirement is approximate; however, the assessor must use requirement sound judgement considering fully the aims of this issue, before accepting solutions that do not strictly meet the above criteria. Controls for wet Adequate TRVs (thermostatic radiator valves) placed in zones around the heating systems building perimeter, and the provision of local occupant controls to internal areas, such as fan coil units, would satisfy the criteria for this BREEAM issue.

There are no additional or different criteria to those outlined above specific to refurbishment projects. If the extended and existing building share the same water systems, then these systems must be assessed against the criteria regardless of whether the existing building forms a part of the assessment or not. If the extension is served by independent systems, only these need be assessed against the Assessment Criteria. If it is the intention that building users of the extended building will use water systems in the existing building, then it must be confirmed that the existing systems comply with the criteria. Design teams may refer to CIBSE TM13 Minimising the risk of Legionnaires disease, 200241 in demonstrating that the design meets the criteria of ACoP. The BREEAM assessor is not required to confirm that the design is compliant with the relevant standard; this is the responsibility of the design team.

For all water systems in the building, a formal letter of declaration from the design team, main contractor or installer of the relevant systems confirming: • The design and installed systems comply with the HSE’s ACoP. • If relevant, any existing water systems comply with the HSE’s ACoP. Where design responsibility is to be passed on to the contractor/installer, a copy of the relevant specification clause(s) stating: • The criteria on the contractor/installer with regards to minimising the risk of Legionnaires disease from the specified water systems. Additional Information Relevant definitions Water systems: For the purpose of this issue, this refers to: • Cooling towers • Evaporative condenser • Domestic hot and cold water systems • Other plant and systems containing water which is likely to exceed 20°C and which may release a spray or aerosol during operation or when being maintained, for example: o humidifiers and air washers o spa baths and pools o car/bus washes o wet scrubbers o Indoor fountains and water features. Legionnaires disease: The HSE describes Legionnaires disease as a type of pneumonia caused by the bacterium Legionella pneumophilia. People catch Legionnaires' disease by inhaling small droplets of water suspended in the air, which contain the bacteria. Humidification Units Humidification options fall into two broad groups; the first group relies on a heated air stream evaporating water vapour either from a pond or stream of water. This includes so-called ‘trickle-down’ systems. These are dependent on sterilisation technologies such as UV, ultrasonic etc, to ensure that the water vapour is not contaminated. Whilst these systems are effective when working properly, any partial failure will allow untreated water into a warmed air stream. Where this occurs, the health-related consequences are likely to be significant. The second group relies on failsafe systems that minimise risk if the plant fails. The only option in this group is steam humidification. This process sterilises the water vapour and ensures that untreated water cannot enter the air stream when no steam is being produced.

Areas used for speech Where the term ‘areas used for speech’ is referenced in this BREEAM issue, it refers to spaces/rooms used for classrooms and worship. If a building type does not contain ‘areas used for speech’ and therefore the reverberation criteria are not applicable, the second credit can be awarded on the basis of compliance with the first credit i.e. two credits can be awarded for complying with the indoor ambient noise level criteria. Where the term ‘unoccupied space’ is referenced in this BREEAM issue, it refers to the nature of the space for the purpose of carrying acoustic calculations or measurements i.e. such measurements must be carried when the space is unoccupied and therefore devoid of sources of noise. Care should be taken to avoid confusing this term with the definition “occupied space” (see relevant definitions) as they have two different meanings within the context of this BREEAM issue. The Additional Information section outlines the criteria for carrying out measurements and calculations to demonstrate compliance with this BREEAM issue. The appointed acoustician must confirm that the acoustic performance has been measured/calculated in accordance with these procedures.

Single occupancy offices: cellular office space designed to accommodate one or two desk spaces/workstations (typically no greater than 10m2). Multiple occupancy offices: Office space that is not cellular in nature i.e. it is open-planned, and designed to accommodate more than two desk spaces/workstations. Occupied space: For the purpose of this BREEAM issue an occupied space is a room or space within the assessed building that is likely to be occupied for 30 minutes or more by a building user (see also description of ‘unoccupied space’ in the Compliance Notes table above). Measurement/calculation procedures The following procedures must be followed by the acoustician when measuring or calculating the levels required to demonstrate compliance with this BREEAM issue (see also compliance note above on measurement procedures): • • • • • • • • Noise from both internal sources (e.g. mechanical ventilation systems, plant noise) and external sources (e.g. traffic noise transmitted via the building façade) should be included, and, where windows are openable as part of the ventilation strategy, these should be assumed to be open for the purposes of calculations and open for measurements. Noise from occupants and office equipment (e.g. computers) should not be included in the measurements. Measurements should be made in at least four rooms in which noise levels can be expected to be greatest either because they are on the noisiest façade or because they are on a naturally ventilated façade. Where different ventilation strategies are used, measurements should be conducted in rooms utilising each strategy. Otherwise, measurements should be made in rooms on the noisiest façade. T in LAeq,T is taken as the duration of the normal working day (typically 8 hours between 09.00 and 17.00). Measurements need not be made over a period of 8 hours if a shorter measurement period can be used. In this case, measurements should be made when external noise levels are representative of normal conditions throughout the day. Measurement periods less than 30 minutes may give representative values for indoor ambient noise levels and may be utilized where this is the case. However measurement periods shorter than 5 minutes should not be used. Measurements should be taken in a minimum of 3 locations in rooms at a height of 1.2 m above the floor level and at least 1 m away from any surface. The above is intended as guidance for undertaking acoustic measurements to demonstrate compliance with the performance requirements in BREEAM. If the acoustician has felt it necessary to deviate from the above procedures, they should provide a justifiable reason for doing so and confirm that the alternative procedures are adequate for demonstrating that the building meets the acoustic performance requirements. NR curves Noise assessments based on NR curves are often used by building services consultants to predict internal noise levels due to mechanical ventilation systems. However, the BREEAM requirement uses the indoor ambient noise level, LAeq,T which includes external noise transmitted via the façade as well as internal noise such as that from mechanical ventilation systems. In the absence of strong low frequency noise, LAeq,T can be estimated from the NR value using the following formula: LAeq,T ≈ NR + 6 dB. Therefore, if the NR value is known, but not the sound pressure levels in the individual frequency bands, an estimate for the indoor ambient noise level LAeq,T can still be determined from the NR value for the building services noise. The LAeq,T for the external noise transmitted via the façade must then be combined with the LAeq,T for the building services. SD5054 issue 4.1 Uncontrolled copy if printed.

Historic Buildings only In addition to the above an additional 2 credits may be awarded (up to a maximum of 15) for carrying out the following: 1. A specialist study has been undertaken by a heritage conservation specialist, who is a full Member of the Institute of Historic Building Conservation, to investigate the implications of improving building fabric performance whilst minimising the potential negative impacts on both the historic character of the building and the condition of the building fabric. 2. The report makes recommendations for potential improvements to the building fabric in accordance with the guidance given in English Heritage’s Balancing the needs for energy conservation with those of building conservation: an Interim Guidance Note on the application of Part L44 and, as a minimum, covers the following issues: a. Each element of the following building elements (as a minimum) must be considered and recommendations for improvements made: i. ii. iii. iv. v. vi. vii. Roof External/Sheltered walls Ground floor Upper floors Windows and external doors Junctions between building elements such as between roof and walls. Junctions between different parts of the building such as between different ages or methods of construction. Where significant improvement cannot be made to an element then the report should state the reason, setting out in detail the conservation and/or building performance issues that have resulted in this recommendation. b. The potential for improvements in ventilation, air tightness and moisture control within the building, ensuring that these are considered in balance with that of the welfare of the historic building fabric. In general, tighter building fabric can be balanced with controlled ventilation improvements (passive and mechanical) and the benefits and disadvantages must be set out together with the recommendations. 3. The study must have been carried out at or prior to concept design stage (equivalent to RIBA stage C or earlier). 4. The building design has implemented and accounted for the study’s recommended improvements and, in particular, demonstrates: • • The design strategy chosen is that which has the greatest impact in terms of potential improvements in energy use, whilst minimising the detrimental impacts on the historic building fabric. That any improvements made to the thermal insulation of the building have been specified in accordance with the recommendations of ‘Thermal Insulation: avoiding risks’’45.

Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Ene 1 Reduction of CO2 Emissions 95 Exemplary level criteria The following outlines the exemplary level criteria to achieve an innovation credit for this BREEAM issue: 1. One additional innovation credit can be awarded where evidence provided demonstrates the building is designed to be a carbon neutral building as defined by the NCM (i.e. in terms of building services energy demand), as follows: a. A new building achieves a CO2 index less than zero on the benchmark scale. b. A refurbished building achieves a CO2 index equal to or less than zero on the benchmark scale. 2. Two additional innovation credits can be awarded where evidence provided demonstrates the building is designed to be a True zero carbon building (in terms of building services and operational energy demand). Compliance Notes New Build New buildings should compare their Energy Rating to the New Build benchmark scale. Refurbishment Existing buildings that have undergone or are undergoing major refurbishment should compare their Energy Rating to the Refurbishment benchmark scale. This separate scale aims to better recognise and encourage the energyefficient refurbishment of existing buildings which results in a significant reduction in the energy demand for that building. Extensions to Where an existing building is being extended (and only the new extension is existing being assessed) and that extension uses existing building services plant, the buildings energy modelling and CO2 Index must be based on the building fabric of the new extension and any existing, common, building services plant and new building services plant installed that will service the new extension. The energy modelling does not have to consider the existing building fabric where this will not form part of the scope of the BREEAM assessment. Nor does it have to consider existing building services where they are not supplying services (heating, cooling and/or ventilation) to the new extension being BREEAM assessed. Part new-build extension part refurbishment For assessments of buildings that are a mixture of new build and existing building refurbishment a weighted benchmark scale is used. The weighted benchmark scale is determined using the area (m2) for new build and area (m2) for refurbishment and the two benchmark scales in Table 9 CO2 index benchmarks and BREEAM credits for new build and refurbishment. If there is a higher proportion of new build to refurbishment then the weighted scale will be biased towards the benchmark scale for new buildings and viceversa if there is a higher proportion of refurbished element. As the benchmarks are influenced by the split in areas between the new build element and major refurbished element of the assessed building, the benchmarks will change if the new build/refurbishment area totals change. To determine the weighted benchmark scale and number of credits achieved, 2 2 the assessor must enter the area (m ) for new build and area (m ) for refurbishment in to the relevant box of the Ene 1 Reduction of CO2 emissions calculator.

Valid on day of printing only © BRE Global Ltd 2012 96 Ene 1 Reduction of CO2 Emissions Renewable and low carbon Installations Accredited external renewables BREEAM Prisons 2008 Where included as part of the project and therefore assessed under this BREEAM issue, the installation of low or zero carbon technologies can be used to off-set the assessed building’s CO2 emissions. The LZC technology can be installed on-site, near-site where a private wire arrangement is in place (see relevant definitions) or off-site via accredited external renewables (see compliance note below). For the purpose of this BREEAM issue accredited external renewables are renewable energy schemes located off-site, but within the UK, which: • • • Are accredited renewables (as defined by the Energy Act 2004). These will be Renewable Energy Guarantee of Origin (REGO) certified Create new installed generation capacity, designed to meet the loads of the building (i.e. not just units of carbon) Are additional to capacity already required under the Renewables Obligation At the time of writing, BRE Global are not aware of a mechanism for accrediting off-site renewables and therefore any renewable energy schemes that meet the above definition; though some ESCOs may achieve these criteria. Energy exported to the grid Any electricity from an onsite LZC energy source that is exported to the grid may be included in the calculations as if it were used within the building. EPC certificates, BREEAM & building use/tenancy arrangement The legislative criteria for an Energy Performance Certificate vary according to building size, use, services and tenancy arrangement. In some instances an EPC will be required for the whole building, in others an EPC will be required for each individual unit or tenanted area within a building. The scope of a BREEAM assessment typically covers the whole building, regardless of whether that building consists of a number of units to be sub let. Where an EPC is required for each unit, for the purposes of determining the number of BREEAM credits, the CO2 index is the total of the area-weighted average of the CO2 index of each individual unit. Where the development contains conditioned common and/or landlord spaces, the area of these spaces, unless otherwise accounted for, should be divided and attributed amongst the separate units. The proportion of common area attributed to each unit must be equivalent to the ratio of each unit’s area as a proportion of the total area of all units. EPC in Scotland All units, heating systems and common areas within the assessed building must be accounted for in the assessment of Ene 1. For further information on the EPC criteria, refer to guidance on the Communities and Local Government Website (see references section). The approach adopted in Scotland for determining an Energy Rating differs from that used in England, Wales and Northern Ireland. Scotland bases its EPC rating on actual CO2 emissions, regardless of building type, whereas an EPC certificate for the other UK countries uses a CO2 Index. Whilst both approaches have their merit, for the purpose of comparing BREEAM-assessed buildings on a ‘level playing field’ a decision has been taken to adopt one approach – the CO2 Index. Using the approved software, buildings located in Scotland can easily determine their CO2 Index by changing the ‘Building Regulations & EPBD parameters’ in the ‘Project details’ tab of the NCM-compliant approved software from ‘EPC Scotland’ to ‘EPC England’ or ‘EPC Wales’ or ‘EPC Northern Ireland’.

The calculation of CO2 emissions can take account of contributions from on-site, near-site and accredited external renewable/low carbon installations. Off-site renewables that are not accredited cannot be used to meet this definition. CO2 Index: The energy performance of a building (for England, Wales and N.I.) is shown on the EPC as a Carbon Dioxide (CO2) based index. It is this index that is used to determine where the building falls on the A+ to G rating scale and the number of BREEAM credits that can be awarded. Dynamic Simulation Model (DSM): A software tool that models energy inputs and outputs for different types of building over time. In certain situations, SBEM will not be sophisticated enough to provide an accurate assessment of a building’s energy efficiency. In these cases Government-approved proprietary dynamic simulation models may be used. Communities and Local Government provide such approval. Historic buildings - For the purpose of assessing this BREEAM issue, historic buildings are defined as: a. Listed buildings b. Existing buildings situated in conservation areas (where the existing building itself has conservation status and contributes to the status of the conservation area) c. Existing buildings which are of architectural and historical interest and which are referred to as a material consideration in a local authority’s development plan d. Existing buildings of architectural and historic interest within national parks, areas of outstanding natural beauty, and world heritage sites. Institute of Historic Building Conservation (IHBC): The Institute of Historic Building Conservation (IHBC) is the professional institute which represents conservation professionals in the public and private sectors in the United Kingdom and Ireland. The IHBC exists to establish the highest standards of conservation practice to support the effective protection and enhancement of the historic environment. Full Membership of the IHBC is open to all whose principal skill, expertise, training and employment is in providing specialist advice for the conservation of the historic environment. Full Members are normally expected to demonstrate skills and experience under all of the IHBC's eight Areas of Competence. Energy Performance Certificate: A certificate that confirms the energy rating of the building from A to G, where A is the most efficient and G is the least efficient. The better the rating, the more energyefficient the building is, and the lower the fuel bills are likely to be. The energy performance of the building is shown as a Carbon Dioxide (CO2) based index. EPCs are generated using approved software by accredited energy assessors. Non-Domestic Energy Performance Certificate Register: A register of accredited energy assessors and Energy Performance Certificates. Using the certificate reference number the validity of the EPC rating for a constructed building can be confirmed. Near-site LZC: renewable energy generated near to the site that is provided for all or part of the community, including the assessed building, e.g. decentralised energy generation linked to a community heat network or renewable connected via private wire. On-site LZC: renewable energy generated on the site of the assessed development. Private wire arrangement: Where used in the context of BREEAM for low or zero carbon technology installations, a private wire arrangement is where any electricity generated on or in the vicinity of the site is fed directly to the building being assessed, by dedicated power supplies. If electricity is generated which is surplus to the instantaneous demand of the building this electricity may be fed back to the National Grid.

In cases where a building is supplied by a communal installation, no carbon benefit can be allocated to buildings which are not connected to the communal installation. Simplified Building Energy Model (SBEM): SBEM is a computer program that provides an analysis of a building’s energy consumption. The SBEM tool is designed to cover buildings that are not dwellings. It has been adopted by government as part of the UK national methodology for calculation of the energy performance of buildings. For more information visit: www.ncm.bre.co.uk/. True zero carbon building: Where net carbon dioxide emissions resulting from energy consumed in the operation of the space heating/cooling, hot-water systems, ventilation, internal lighting AND process related energy consumption is zero or better. The calculation of CO2 emissions can take account of contributions from on-site, near-site and accredited external renewable/low carbon installations. Off-site renewables that are not accredited cannot be used to meet this definition. SD5054 issue 4.1 Uncontrolled copy if printed.

Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to Where an existing building is being extended and it has existing building existing services plant and systems that will be common to both the new extension and buildings existing building, the criteria for energy metering cover the entire building. Lighting & small power Other major energyconsuming items Modular boiler systems Due to traditional distribution methods, it can be difficult to cost-effectively separate lighting and small power. It is acceptable, within a single floor, for lighting and small power to be combined for metering purposes, provided that sub-metering is provided for each floor plate. Other major energy-consuming items, depending on the building type, might include, for example, plant used for swimming or hydrotherapy pools, kitchen plant, cold storage plant, laboratory plant, sterile services equipment, transportation systems (e.g. lifts & escalators) drama studios and theatres with large lighting rigs.

The assessor must ensure that several low watt fittings are not being specified in place of one higher watt but overall more energy-efficient fitting. This compliance note is to allow for the specification of innovative low energy light sources, such as LEDs. Decorative lighting and floodlighting must not be exempt from the assessment criteria although temporary lighting such as theatrical, stage or local display installations, where specified, may be excluded. The criteria are concerned only with general external lighting e.g. way-finding, car parking, decorative, signage, landscape, storage areas etc. Lighting specified for specific prison security purposes does not need to be assessed against the BREEAM criteria.

Assessor’s building/site inspection photographic evidence confirming: • External lighting controls. but ‘as built’ AND and Manufacturers’ literature confirming: • Technical spec for the installed external light fittings. Additional Information Relevant definitions Colour rendering index (Ra): A measure, between 0 and 100, of the ability of a lamp to reproduce the colour of objects in comparison to their aspect under a natural or reference source of light. An incandescent source has a Ra of 100 and a low pressure sodium source a Ra of 0 (see below for further information on colour rendering). Construction zone: For the purpose of this issue the construction zone is defined as the site which is being developed for the BREEAM-assessed building and its external site areas i.e. the scope of the new works. Daylight Sensors: A type of sensor that detects daylight and switches lighting on at dusk and off at dawn. Luminous efficacy in lamp Lumens per circuit Watt: The ratio between the luminous flux produced by a lamp (in Lumens) and the total power consumed by both the lamp and its associated control gear (in Watts). Time switch: A switch with an inbuilt clock which will allow lighting to be switched on and off at programmed times. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Ene 4 External Lighting 105 Colour Rendering At night time, the sensitivity of the eye is shifted towards the blue region of the visual spectrum. As a result, lamps with poor colour rendering index, such as some sodium lamps that emit light between the yellow and red region of the visual spectrum, require more luminous output to light an object with the same level of brightness than a source with better colour rendering index. Sources with a poor colour rendering index also make the differentiation of coloured objects more difficult for individuals. In BS 5489-1:200349 Code of practice for the design of road lighting - Part 1: Lighting of roads and public amenity areas, this is acknowledged by allowing a relaxation of the lighting levels (illuminance levels) required when the source specified has a colour rendering index Ra greater than or equal to 60. The colour rendering index requirement means compliance with this issue using sources of light with a poor colour rendering index is harder to achieve than those with an index greater than or equal to 60. Other benefits of using sources with an index greater than 60 include an increased feeling of safety for individuals, making recognition of spaces and other individuals easier. In areas where CCTV is used, the colour rendering index of lighting sources is critical; an Ra value of at least 80 is recommended (but not required by BREEAM).

Assessment Criteria The following demonstrates compliance: First credit 1. A feasibility study has been carried out by an energy specialist (see Compliance Notes) to establish the most appropriate local (on-site or near-site) LZC energy source for the building/development. This study covers as a minimum: a. b. c. d. e. f. g. h. i. j. Energy generated from LZC energy source per year Payback Land use Local planning criteria Noise Feasibility of exporting heat/electricity from the system Life cycle cost/lifecycle impact of the potential specification in terms of carbon emissions Any available grants All technologies appropriate to the site and energy demand of the development. Reasons for excluding other technologies. 2. A local LZC energy technology has been specified for the building/development in line with the recommendations of the above feasibility study. 3. The feasibility study has been carried out at RIBA stage C (concept design) or equivalent procurement stage. OR 4. The organisation that occupies the building has in place a contract with an energy supplier to provide electricity for the assessed building/development from a 100% renewable energy source. This supply must be delivered by an accredited external renewable source. The contract must be valid for a minimum of 3 years from the date the assessed building becomes occupied. Second credit 1. The first credit for a feasibility study must be achieved. 2. A local LZC energy technology has been installed in line with the recommendations of the above feasibility study and this method of supply results in a 10% reduction in the building’s CO2 emissions. 3. Figures used for calculations of the percentage carbon reduction provided by LZC technology are based on the output from approved energy modelling software.

The first credit for a feasibility study must be achieved. 2. A local LZC energy technology has been installed in line with the recommendations of the above feasibility study and this method of supply results in a 15% reduction in the building’s CO2 emissions. 3. Figures used for calculations of the percentage carbon reduction provided by LZC technology are based on the output from approved energy modelling software. Exemplary level criteria The following outlines the exemplary level criteria to achieve an innovation credit for this BREEAM issue. 1. The first credit for a feasibility study must be achieved. 2. A local LZC energy technology has been installed in line with the recommendations of the above feasibility study and this method of supply results in a 20% reduction in the building’s CO2 emissions. 3. Figures used for calculations of the percentage carbon production provided by LZC technology are based on the output from approved energy modelling software. Buildings complying with the exemplary level criteria would therefore achieve four credits for this issue.

Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to There are no additional or different criteria to those outlined above specific to existing the assessment of extensions to existing buildings. buildings Feasibility study When undertaking a feasibility study at a later stage than outline proposals, an additional element will need to be included in the report to highlight the local LZC energy sources which have been discounted due to the constraints placed on the project by the late consideration, and the reason for their omission. If the feasibility study discounts all local LZC as unfeasible due to the late stage in the project that the study was commissioned, then the credit for the feasibility study must be withheld. If the feasibility was commissioned at the outline proposals stage or earlier and in the unlikely event the study concludes that the specification of any local LZC technology is unfeasible, the first credit can still be awarded. Subsequent credits for installing LZC technology that meets a percentage of building energy demand will not be achievable. SD5054 issue 4.1 Uncontrolled copy if printed.

The following list details the technologies recognised by the BERR, LCBP at the time of going to print: Solar • Solar hot water • Photovoltaics Water • Small scale hydro power • Tidal power • Wave power Wind • Wind turbines Biomass • Biomass single room heaters/stoves • Biomass boilers • Biomass community heating schemes Combined Heat and Power (CHP) for use with the following fuels: • Biomass • Natural gas • Sewerage gas and other biogases CHP systems must meet the threshold criteria for good quality CHP as set by DEFRA’s CHPQA programme50 Community heating, including utilising waste heat from processes such as large scale power generation where the majority of heating comes from waste heat (see also Compliance Notes below). Heat Pumps • Ground source heat pumps • Water source heat pumps • Geothermal heating systems • Air source heat pumps For heat pumps to comply, the heat source (ground or water) must be from a renewable source, for example soil, outside air, ground water, or a river. Other • Fuel cells using hydrogen generated from any of the above ’renewable’ sources The list above is not a definitive list of technologies compliant with BREEAM, but a list of those technologies that may be considered to comply. If the assessor has a justified reason to doubt the low or zero carbon credentials/feasibility of the above technologies, where specified for a development they are assessing, they can justifiably withhold the available BREEAM credits.

Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Ene 5 Low or zero carbon technologies LZC technology not listed Other systems may be acceptable as part of a LZC strategy under this issue but are not inherently considered as LZC technologies. Acceptability will be dependent on the nature of the system proposed. The BREEAM Assessor must confirm acceptability with BRE if in doubt. Waste heat from a building related operational process Waste heat from a process that takes place within the assessed building (or on the assessed site), for the purpose of this BREEAM issue, can be considered as ‘Low carbon’. This is on the condition that the generation of the heat from the process is integral to the assessed building. Waste incineration Waste heat from an incineration plant can only be considered as a low carbon for the purpose of this BREEAM issue under the following circumstances: 1. All other LZC technologies have been considered and discounted in the feasibility study. And either 2. The Local Authority or region in which the incineration plant is located is demonstrably meeting its annual waste reuse/recycling targets and waste management policies. Or 3. A near- or onsite facility connected to the building, via a private wire arrangement, which demonstrably removes re-usable and recyclable waste material prior to incineration. Given the current uncertainty over their impact on biodiversity, global food production and green house gas savings, plus the ease of inter-changeability between fossil fuels, BREEAM does not recognise or reward building systems fuelled by first generation biofuels manufactured from feedstock’s e.g. biofuels manufactured from sugars, seeds, grain, animal fats etc. BREEAM will recognise systems using second generation biofuels (see relevant definitions) or biofuels manufactured from biodegradable waste materials e.g. biogas, or locally and sustainably sourced solid biofuels e.g. woodchip, wood pellets. Biofuels Community and off-site schemes Export to the grid More than one technology Building assessed part of a larger development LZC technology already available on site Calculation of the CO2 emissions saved 109 ‘Local’ does not have to mean on-site and community schemes (near site) can be used as means of demonstrating compliance. As this BREEAM issue seeks to encourage the installation of on-site and near-site LZC technologies, accredited external renewables (accept where stated to achieve one credit) cannot be used to demonstrate compliance with the criteria of this BREEAM issue. Any electricity from an onsite LZC energy source that is exported to the grid may be included in the calculations as if it were used within the building. The percentage can be made up from more than one of the above technologies. Where the building under assessment forms part of a larger development and either a new or existing LZC installation is provided for the whole site, then the amount of LZC energy generation counted for in this issue, and subsequent CO2 emissions saved, should be proportional to the building’s energy demand compared to the total energy demand for the site (see also note below on existing LZC technology). For developments where there is an existing LZC energy source that can supply a compliant percentage of energy to the assessed building, a feasibility study will still have to be carried out to demonstrate that the existing technology is the most appropriate for the assessed building/development. The study should seek to identify any other options to supply a higher proportion of the building's energy demand in addition to that supplied by the existing source. When calculating the energy contribution and CO2 emissions saved from the LZC installation the following rules should be applied: • The net yield of the LZC installation(s) must be used (i.e. subtract any CO2 related to the energy used by the LZC technology itself such as pumps, inverters, controllers, etc).

Valid on day of printing only © BRE Global Ltd 2012 110 Ene 5 Low or zero carbon technologies • BREEAM Prisons 2008 The percentage CO2 savings should be calculated using the following assumptions: o Renewable heat energy is displacing gas where the location for the building would practically have access to a gas connection. Where there is no access to a gas connection assume oil is being displaced.* o Renewable electrical energy is displacing grid electricity at the national CO2 conversion rate. * The design team is required to provide the assessor with sufficient justification that gas is not available.

In such instances the design team must provide the assessor with an adequate statement of justification as to why this is the case. The assessor must use their discretion in determining the validity of the case and reference any justification and design team statement in the formal BREEAM report. No heated or air conditioned areas Where the scope of the building specification covers fitted-out elements and the building is designed to be untreated then the requirement to comply with the ‘as built’ performance measures can be omitted. The design measures are still applicable for future-proofing i.e. in the event that the building at some point has heating and/or air conditioning plant installed. Scope of the issue This issue is applicable only for assessments of buildings that have a warehouse storage/operational area and/or dedicated vehicle delivery bays/access. Where this is not the case the issue will be filtered from the list of applicable issues by the BREEAM assessor’s spreadsheet tool. Where the issue is applicable, the ‘as built’ performance measures i.e. the requirement for a thermographic survey applies to the whole building, not just the warehouse/delivery area (to ensure completeness of the measures).

Valid on day of printing only © BRE Global Ltd 2012 130 Tra 1 Provision of public transport Operating hours BREEAM Prisons 2008 BREEAM seeks to define the building’s accessibility to the public transport network for the period during which the majority of building users will travel to and from the building. In most cases the normal operating hours of the building can be used; however, some buildings will operate for 24 hours a day and on a shift work basis. As a result, during what typically would be deemed unsociable hours and therefore periods where a) there is little if any public transport operating and b) the number of total building users travelling to the building during this time is a minority; such periods are not required to be accounted for in the assessment of this issue. Where the assessed building operates on a 24-hour basis, or the operating hours are unknown at the time of assessment, then refer to and use the table of default operating hours, which can be found in the Additional Information section of this issue. Compliant public transport node Average number of services A compliant node includes any bus stop within 650m and any railway station within 1000m of the assessed building’s main entrance, measured via a safe pedestrian route (not ‘as the crow flies’). The service stopping at each node must provide transport from, or onward travel to, either an urban centre, major transport node or a community focal point e.g. doctor’s surgery, library, school or village centre. Only local services should be assessed and any national public transport services should be excluded from the analysis, unless such a service can be said to provide a local commuter service. There is no limit on the number of nodes that can be considered when calculating the AI, provided they all meet the above criteria. For the purpose of the calculation, the frequency of public transport is the average number of services per hour. This is calculated by determining the number of stopping services at the node during the operating hours, divided by the number of hours within the operating period. For example: the average number of services for an assessment of a building that operates between 8am - 7pm (11 hours) and is within proximity of a bus stop with 35 stopping services during this period is 3 (equivalent to an average service frequency of 20 minutes). Typical day The typical day is that which represents the period when travel to and from the building by staff/users and visitors will be at its highest. For most buildings this should be taken as a mid-week day. In choosing a typical day the assessor should check that the timetabled information for that day is, within reason, representative of the public transport provision for the entire operating week (excluding Sundays). Multiple services Services that operate from more than one node within proximity of the building, i.e. two separate bus stops served by the same bus, must be considered only once - at the node in closest proximity to the building. Different services at the same node, however, should be considered as separate entities. Bi-directional routes Routes will be bi-directional; however for the purpose of calculating the index, consider only the direction with the highest frequency (in accordance with the PTAL methodology). Where a dedicated company bus service is provided for building users during, or before or after, operating hours (as defined in above), the building entrance can be substituted for the drop-off/pick-up destination point of this service and therefore public transport accessibility measured from that point.

And the shortest of the following periods - Either • The transport facilities will be available for use by the time 25% of all phases have been completed and are ready for occupation. Or • The transport facilities will be available for use within 25% of the total build time for the phase in which the assessed building forms a part, measured from the completion date of that phase. The most appropriate rule for the development in question must be used, ensuring that the time building users have to wait before having use of the transport facilities is as short as possible. Where the transport facilities will not be available for use within a period of five years from occupation of the building, they cannot be considered for determining compliance with the BREEAM criteria.

Alternatively, the same node with one service every 15 minutes, but 300m from the building entrance will achieve an AI of 2.26.

This map can be found at: http://www.london.gov.uk/thelondonplan/maps-diagrams/map2a-03.jsp The map shows the Public Transport Accessibility Levels throughout London (PTALs range from 1-6); the PTAL is determined using the AI as follows: PTAL AI 1 0.00 – 5.00 2 5.01 – 10.00 3 10.01 – 15.00 4 15.01 – 20.00 5 20.01 – 25.00 6 25.01 + As an example, if the building is located in an area of London that has a PTAL of 2 this could have an AI at any point in the 5-10 range. As such, for the purpose of BREEAM, the lower AI of 5 must be assumed and the credit awarded accordingly, or alternatively the specific AI for the assessed building can be determined using the TRA 1 Provision of Public Transport calculator and, potentially, a higher number of credits awarded.

Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to Refer to the compliance note below on existing compliant facilities. existing buildings Building users Where the term building users is referenced this refers to the staff, therefore the number of staff that will work within the building must be used to determine the number of compliant facilities that must be provided to achieve the credit. Whilst staff numbers are the means by which compliance with the assessment criteria is determined, the percentage requirements account for visitors and patients (if applicable to scheme) that will travel to and use or work within the building. As such the compliant cycle facilities must be accessible to all these types of building users. Compliant cycle storage space Compliant cycle storage facilities are those that meet the following: • • The space is covered overhead and protected from the rain The covered area and the cycle racks are set in or fixed to a permanent structure (building or hardstanding) and allow both the wheel and frame to be locked securely (e.g. Sheffield type). Or racks are located in a locked structure fixed to or part of a permanent structure with CCTV surveillance. SD5054 issue 4.1 Uncontrolled copy if printed.

Vertical racks, which allow direct access (without the need to get alongside the locked bike) and permit one bike per vertical stack can comply with the criteria (provided all other criteria are met). For this type of rack, the distance between each rack can be less than 1.0m but not less than 600mm (the typical width of a bike across the handlebars). Where a proprietary (manufactured) bicycle storage system is specified BREEAM allows an element of flexibility with respect to the requirements and dimensions outlined in the compliance note above. The degree of flexibility is at the discretion of the BREEAM Assessor, but the system must allow ease of access for the user and each cycle to be removed independently of other stored bikes, must protect the bikes from rain, and allow cyclists to lock at least one wheel and the frame of their bikes adequately. If the assessor believes that a system does not meet these basic objectives then they should not award the credit. Where awarding the credit for a proprietary system that does not meet the space/access/weatherproofing/security dimensions and requirements (outlined above) the Assessor must fully justify their decision to award the credit in these circumstances. Non compliant cycle racks These types of cycle storage devices do not comply with BREEAM: • Hooks and wall attachments • Single wheel (butterfly) bike rack holders (these racks provide less security and can cause damage to bike wheels). Compliant showers One shower must be provided for every 10 cycle storage spaces and both male and female users catered for i.e. either separate showers within shared gender-specific facilities or single shower cubicles and changing space for mixed use. The showers can be available for others to use in addition to cyclists. Changing facilities and locker criteria; • The assessor can use their judgement to determine whether the changing area is appropriate given the number of cycle storage spaces/showers provided. As guidance to aid the assessor, where a shower/changing cubicle is provided there should be a minimum of one square metre of changing space adjacent to the shower(s) with a bench seat and hooks for hanging clothes.

Waterless urinals Due to overriding health and safety concerns in some healthcare facilities, the specification of waterless urinals may not be feasible. In such cases, compliance can be sought by one of the other available means, e.g. ultra low flush volume or infra-red proximity. In some cases, the use of water-efficient fittings and appliances may not be appropriate to the needs of the patient, and inappropriate specification may adversely affect the incidence and propagation of infections. In such instances, the assessor will need to confirm with the BREEAM office the approach for assessing this issue in these building areas. Furthermore, the design team should consult NHS guidelines concerning appropriate selection of sanitary fittings and fixtures and the control of legionella.

Effective flush volume: The volume of water needed to clear the toilet pan and transport any content far enough to avoid blocking the drain. Dual Flush Cisterns: Devices that have the facility to provide lower flush volume for liquids and higher flush volume for solids and paper. Calculating the effective flushing volume of dual flush toilets: For dual flush WCs the ratio full flush:reduced flush is taken to be 1:3 for non-domestic buildings. The effective flush volume can therefore be calculated as follows, using a 6/4 litre dual flush volume WC: ((6 Litre*1) + (4 Litre*3))/4 = 4.5 Litre effective flushing volume Product Certification of Low Flush WCs Product certification schemes provide specifiers and clients with greater assurance of manufacturers’ claim regarding the performance of the actual flush volume of their products and therefore the potential water savings of different products. At present BREEAM does not require that the flushing volume of WCs (or any other water-consuming device) meet an approved standard to gain BREEAM credits.

Assessment Criteria The following demonstrates compliance: 1. The specification of a water meter on the mains water supply to each building; this includes instances where water is supplied via a borehole or other private source. 2. The water meter has a pulsed output to enable connection to a Building Management System (BMS) for the monitoring of water consumption. 3. If there is a swimming pool on site within the scope of the assessment, the building housing it must be covered by a separate meter in accordance with the above criteria. The changing facilities (including showers, toilets etc) housed in this building should also be covered by this meter. Exemplary level criteria The following outlines the exemplary level criteria to achieve an innovation credit for this BREEAM issue: 1. Where sub meters are fitted to allow the metering of individual water-consuming plant or building areas, where demand in such areas will be equal to or greater than of 10% of the total water demand of the building (see also compliance note). 2. Each sub meter has a pulsed output to enable connection to a Building Management System (BMS) for the monitoring of water consumption.

Refurbishment There are no additional or different criteria to those outlined above specific to refurbishment projects. Extensions to If no new water supply is being installed because occupants of the extended existing building will use the facilities in, and therefore water supply to the existing buildings building, then the issue should be assessed on the basis of whether a compliant water meter is installed on the existing supply. No water supply to the building/unit If there is no water supply to the building during operation because there will be no installed water-consuming fittings in the building, then the issue must be assessed on the basis of the water supply to the nearest accessible building with such facilities, likely to be used by the future occupants of the assessed building.

Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Exemplary criteria level Wat 2 Water Meter 151 It is widely accepted that water usage can be decreased by how water is consumed by building users. If there are only small water consuming units used within the building such as singular toilets, small kitchen etc. It is unlikely there will be an opportunity to reduce water consumption by increased water management. And therefore there will be no benefit to installing a sub-meter; in such instances the exemplary credit is not available. Compliance with the criteria can also be demonstrated where the water metering/monitoring equipment is integral to the water consuming plant, as oppose to a sub meter on the water supply to the plant. Schedule of Evidence Required Req. Design Stage All A copy of the specification clause confirming: • The specification and type of water meter(s).

If connected to a BMS, the assessor’s site inspection confirming live meter readings can be used in lieu of manufacturer’s details confirming specification of a pulsed output. Additional Information Relevant definitions None. The requirement for a pulsed output has been included to encourage the use of meters capable of transmitting (by wire or wirelessly) a continuous or pulsed signal with water management information such as total water consumed or flow rate to a Building Management System. This allows demand patterns on water systems to be monitored and evaluated over time.

Pre-set flow rates and time periods will vary depending on the building type and usage. System criteria It is anticipated that this credit will usually be achieved by installing a system which detects higher than normal flow rates at meters and/or sub-meters. It does not require a system that would directly detect water leakage along part or the whole length of the water supply system.

Shut-off systems Shut-off systems may control combined toilet areas, such as male and female toilets within a core. Proximity detection criteria Single WCs Proximity detection shut-off is not required for each individual sanitary appliance to achieve the credit. The requirement is for the water supply to be isolated for each toilet block on a floor when not being used by the occupants. The criteria for this issue apply to facilities with a single WC (potentially within smaller or low occupancy buildings). In these instances shut-off can be provided via the same switch that controls the lighting (whether proximity detection or a manual switch).

Assessor’s building/site inspection and photographic evidence confirming: • The location and installation of proximity detection controls. A design plan showing: • The location of the toilet facilities. AND ‘As built’ drawings showing: • The specification of shut-off valves Additional Information Relevant definitions Solenoid valve: An electrically operated shut-off device that controls the flow of water in pipes. Volume controller: An automatic control device to turn off the water supply once a maximum preset volume is reached. Programmed time controller: An automatic time switch device to switch the water supply on and/or off at predetermined times. Light fittings in toilets are often controlled by proximity detection by IR movement detectors or sensors placed at entry doors (the latter can be less accurate as more than one person can enter or depart in the opening of one door). The sensors used to control the lighting can also be linked to a solenoid valve in the cold water supply. This will then act as a proximity detection system. Small water leaks can result in significant losses over time, increasing costs as well as causing damage. There is a significant risk of leaks going undetected, particularly as toilet accommodation is often unoccupied for long periods. A proximity detection shut-off system prevents waste water from minor leaks by shutting off the water supply when toilet accommodation is not occupied. Valves in cisterns supplying urinals and WCs are especially prone to failure, leading to wastage of water via the overflow. Whilst leakage from any valve is variable, a typical value for a leaking valve toilet might be 4 litres/day. SD5054 issue 4.1 Uncontrolled copy if printed.

If the assessment is of the new build extension and existing building i.e. whole building, then the roof catchment area is taken as the whole roof area of the building. Rainwater collection tank size Of the two options available for demonstrating compliance, it is the option with the lesser of the two figures (litres) that should be specified and therefore used to demonstrate compliance. For example it would not be expected to size a system that collected significantly more rainwater over the defined period than was required to meet flushing demand in the building over the same period, unless the collection system is being used to meet landscape irrigation demand or forms part of a storm water management strategy.

Total predicted flushing demand can be estimated by the design team on the basis of the following variables: • Number of building users (staff and visitors/students/users as applicable) • Effective flush volume of WCs/urinals • Estimated number* of WC/urinal uses per person per day (multiplied by the defined period of collection) * For staff use, unless other data is available, assume 1.3 WC uses per person per day and 2 urinal uses per person per day (assume that only 50% of the building occupants will use urinals). Schedule of Evidence Required Req. Design Stage Post Construction Stage All A copy of the specification clause confirming: • Type of collection system specified. • WC, urinal, taps and shower specification (where appropriate). Assessor’s building/site inspection and photographic evidence confirming: • The installation of the collection system. Design team calculations for the defined period of collection demonstrating (where appropriate): • Rainwater yield for the catchment area (mm) • Predicted WC/urinal flushing demand • Estimated potential for waste water collection from taps/showers/other process (where applicable). • Size (litres) of the rainwater/greywater collection tank specified. Where changes have occurred since design stage assessment, a revised copy of the technical specification and sizing calculations for the installed system. Additional Information Relevant definitions Defined period of collection: For the purpose of assessing this Issue the defined period of collection is 18 days. This is equivalent to approximately 5% of annual rainfall yield. Potable water: Defined as drinkable and/or mains supplied water. This definition includes water obtained by borehole abstraction and water sourced from rivers, mountain streams, lakes etc. Catchment area: An area that catches rainfall and delivers it to a collection tank for re-use.

Calculating compliance The following formula can be used to calculate the volume of collectable rainwater for the assessed building’s catchment area for the defined period of collection: ∑ (ARF x C x Rco-ef x Fco-ef x Dcol) Where: ARF = Annual rainfall for the site location (mm) C = Rainwater catchment area (m2) Rco-ef = Run-off co-efficient Fco-ef = Filter co-efficient. Dcol = Defined period of collection: 18 days/365 days = 0.05 Annual rainfall: The local EA, SEPA, EHS office or the Met Office should be able to supply rainfall data. Run-off co-efficient: A coefficient is used to adjust the tank size calculation to allow for the fact that not every drop of rain that falls within the catchment area will be collected by the tank. Drainage coefficient is dependent on the type of roof specified for the building, flat roofs having a lower co-efficient. Below are some typical co-efficient factors: Roof type Run-off co-efficient Pitched roof tiles 0.75 - 0.9 Flat roof smooth tiles Flat roof with gravel layer 0.5 0.4 – 0.5 Filter co-efficient: Not all the water that drains from the roof down the gutters will reach the holding tank; the filter co-efficient accounts for this. Most manufacturers/installers of systems will recommend a filter co-efficient of 90% i.e. 0.9. Drainage and filter co-efficiencies can be found in CIRIA guidance57, though these should be in the design team’s sizing calculations. Example calculation: Average annual rainfall for the site location (mm) 757mm Roof catchment area (m2) 3,500m2 Drainage co-efficient (tiled pitched roof) 0.8 Filter co-efficient. 0.9 Defined period of collection 0.05 Volume of rainwater for the defined period of collection 95,382 Litres An installed rainwater collection tank with a capacity of 50,000 litres would therefore collect 52.4% of the total predicted rainwater run-off from the roof catchment area for the defined period of collection.

Exemplary level criteria The following outlines the exemplary level criteria to achieve an innovation credit for this BREEAM issue. 1. One exemplary BREEAM credit can be awarded as follows: a. Where assessing four or more applicable building elements, the building achieves at least two points additional to the total points required to achieve maximum credits under the standard BREEAM criteria. b. Where assessing fewer than four applicable building elements, the building achieves at least one point additional to the total points required to achieve maximum credits under the standard BREEAM criteria. Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new-build projects. Refurbishment For each element that is reused in situ, BREEAM allocates an ‘A+’ rating and these elements should also be included in the ‘A+’ rated area in the MW1 calculator. New elements specified as part of a refurbishment project, e.g. windows, must be assessed as outlined above. Extensions to Any applicable new-build elements, forming part of the new extension, must be existing assessed as outlined above. If the existing building forms part of the scope of buildings the assessment, then any existing applicable element that is reused in situ achieves an ‘A+’ rating, as outlined above for refurbishments. Green Guide Online Refer to the Additional Information section below for guidance on using the online Green Guide to Specification and accessing the appropriate ratings for the assessed elements. Element consisting of more than one specification Where more than one specification is present for a given element, the rating and area for each specification should be entered into the tool and an average points score is calculated (by area). Finding exact Green Guide Ratings No Green Guide rating match Whilst exact matches in specifications are not always found, it should be possible to identify a similar specification and use its rating for the purposes of assessment (also see note below ‘No Green Guide rating match’). Where a Green Guide rating cannot be found for a specification BREEAM Assessors can use the online Green Guide calculator to determine a bespoke Green Guide rating for the specification. Licensed BREEAM Assessors can access the calculator via www.thegreenguide.org.uk. If a required component is not present via the online calculator, The BREEAM Assessor will need to submit a standard Bespoke Green Guide Query proforma, from which BRE Global will calculate the rating and confirm the result to the Assessor.

Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 New elements containing reused materials Mixed use developments Single storey buildings and upper floors Exemplary level criteria requirements where building contains no upper floor Mat 1 Materials Specification (major building elements) 163 If a new element is specified e.g. external wall, and part of that element includes a reused material e.g. reclaimed bricks, assessors should seek guidance from BRE on the appropriate rating. Where the assessment covers only some of the floors in the building, the roof must still be assessed as it is protecting the assessed building below. If the roof is directly above domestic accommodation (e.g. flats), the equivalent domestic Green Guide rating for the roof must be used as opposed to the ratings for non-domestic roofs. Roof areas not protecting parts of the assessed building/space can be omitted from the assessment. Where the assessed building is a single storey building and therefore has no upper floors, the upper floor element does not need to be assessed. In such instances the BREEAM assessor’s Mat 1 Calculator will re-calculate the requirement and award the available credits in accordance with the Green Guide ratings for the remaining applicable elements. Where there is no upper floor slab in the building the Mat 1 calculator tool adjusts the points to credit benchmark scale. As such, to achieve three credits 4 points must be achieved. In accordance with requirement 1b of the Exemplary level criteria 5 points must be achieved to award the additional credit for compliance with the Exemplary Level Criteria. The maximum number of points that can be achieved where there is no upper floor slab, i.e. where all remaining elements achieve an A+ Green Guide rating, is 6 points. Schedule of Evidence Required Req. 1& Exemp. level req. Design Stage Specification confirming: • A detailed description of each applicable element and its constituent materials. Post Construction Stage Assessor’s building/site inspection and photographic evidence confirming: • Element in-situ (where possible) AND Design drawings or specification detailing: • Location and area (m2) of each applicable element.

Additional Information Relevant definitions Ecopoint: The Ecopoint used in the Green Guide online is single score that measures the total environmental impact of a product or process as a proportion of overall impact occurring in Europe 100 Ecopoints is equivalent to the impact of a European Citizen. Green Guide ratings are derived by sub-dividing the range of Ecopoints/m2 achieved by all specifications considered within a building element. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 164 Mat 1 Materials Specification (major building elements) BREEAM Prisons 2008 Green Guide to Specification: The Green Guide to Specification is an easy-to-use comprehensive reference website and electronic tool, providing guidance for specifiers, designers and their clients on the relative environmental impacts for a range of different building elemental specifications. The ratings within the Guide are based on Life Cycle Assessment, using the Environmental Profile Methodology. www.thegreenguide.org.uk Green Guide element number: A unique BRE Global reference number given to a Green Guide rating for any particular building element type specification. Both standard Green Guide ratings and those calculated using the Online Green Guide calculator will have an element number. Reused materials: are materials that can be extracted from the waste stream and used again without further processing, or with only minor processing, that does not alter the nature of the material (e.g. cleaning, cutting, fixing to other materials). The Mat 1 Calculator: A spreadsheet-based calculator required to determine the number of credits achieved for this BREEAM issue based on each applicable element’s Green Guide rating. The Mat 1 Calculator makes four adjustments to the points achieved for each specification/element assessed, as follows: 1. The first is the scoring based on the Green Guide rating; A+ =3, A=2, B=1, C=0.5, D=0.25 and E=0. 2. The second, where an element consists of several different specifications, is to weight the points achieved according to the relative area and Green Guide rating of each of the individual specifications. So if 50% of an element was A+ and 50% was C, the score would be (50%*3) + (50%*0.5) = 1.75. 3. The third is to weight based on the overall area of different elements - this is done by multiplying the area of each element by the weighted Green Guide score, adding the total for all elements and then dividing by the total area of the assessed elements. As a 20 storey office block will have a smaller roof area than floor area, so the area weighting will take this into account by giving a smaller weighting to the score for the roof than the external walls. 4. The final adjustment relates to the Ecopoints range for each assessed element. This adjustment ensures the environmental impact of the element in relation to the impacts of other assessed elements within the building is considered. For example; the external walls have a larger Ecopoints range than the internal walls, therefore, if both elements achieve the same Green Guide rating the rating of the external walls achieves a higher proportion of the overall points than the rating for the internal walls, thus recognising the relatively higher reduction possible in the environmental impact of the external walls, due to the larger Ecopoints range for that element. Online Green Guide calculator: BRE Global have created the Green Guide Calculator to enable BREEAM and CSH assessors to quickly and efficiently generate Green Guide ratings for a significant proportion of specifications not listed in the Green Guide Online. The Green Guide Calculator database is based on the components currently used to create specifications within the Green Guide Online. These components can be selected and combined to generate instant Green Guide ratings for a multitude of different specifications. To access the Green Guide Calculator, you must be a licensed BREEAM/EcoHomes/Code for Sustainable Homes Assessor. Please note that, at the time of writing, the Green Guide Calculator is not yet available for public use. Using the Green Guide to Specification The Green Guide categorises ratings by building type and element. When using the Green Guide online, (www.thegreenguide.org.uk), the main page asks the user to select a building type. Where assessing common elements (see below) any building type can be selected. To obtain appropriate ratings for elements that are not common (upper-floors and roofs), select the ‘healthcare’ category. For prison building types that are more akin to commercial buildings in their construction e.g. visitors centres, catering buildings, sports halls select the ‘offices’ (commercial) category. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Mat 1 Materials Specification (major building elements) 165 These categories include ratings that are most appropriate to the elemental specifications used for these types of prison buildings.

Assessment Criteria The following demonstrates compliance: 1. Where at least 80% of all external hard landscaping and boundary protection (by area) achieves an A or A+ rating, as defined in the Green Guide to Specification. Green Guide ratings for the specification(s) of each element can be found at: www.thegreenguide.org.uk Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new-build projects. Refurbishment For each element that is reused in situ, BREEAM allocates an ‘A+’ rating. New & existing elements specified as part of a refurbishment must be assessed as outlined elements above. Extensions to existing buildings Green Guide Online There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. Finding exact Green Guide Ratings Whilst exact matches in specifications are not always found, it should be possible to identify a similar specification and use its rating for the purposes of assessment. Where no similar specification can be found, seek guidance from BRE for the appropriate rating. Where less than 20% of the total area of existing hard landscaping and boundary protection elements are subject to minor alterations or maintenance, these elements are awarded an A+ rating for the purposes of this analysis. If one of the elements is not present, e.g. boundary protection, then the credit must be assessed on the basis of the specification of the single element e.g. hard landscaping. Where the development has neither element, the credit can be awarded. Minor alteration of existing elements No hard landscaping or boundary protection Building façade forming boundary Existing natural features When using the Green Guide for the purpose of assessing this BREEAM issue, ratings for landscaping elements are common across all building types. The rating will therefore be the same irrespective of the building type selected via the Green Guide online. Any part of an external building façade (of either the assessed building or any other neighbouring building) that forms a part of the site boundary should be excluded from the assessment of this credit. Any existing or specified natural boundary protection (such as hedging or other living barrier) should be awarded with an A+ rating for the purposes of this analysis.

Where an existing building is being reused and/or extended and the function/purpose of the new building will be the same as that which the existing building was used for, i.e. there is no change of use, the credit can be awarded where: a. At least 25% of the façade by area of the total building is to be reused; b. At least 80% of the façade by mass of the existing building is made up from in-situ reused material. The criteria in this instance are reduced as the existing building is likely to require less remedial work as it is not subject to a change of use.

For any other materials that form a part of an applicable building element, but do not fit into the applicable materials list or the exclusions list, please refer to BRE who will identify the relevant Key Process and Supply Chain Process or Processes. 2. Each applicable material is assigned to a responsible sourcing tier level based on the level and scope of certification achieved by the material supplier(s)/manufacturer(s) (see SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Mat 5 Responsible sourcing of materials 173 Table 13 Responsible Sourcing Tier Levels and Criteria in the additional guidance section). 3. Follow the Calculation Procedure outlined in the additional guidance section, and use the Mat 5 Responsible Sourcing Calculator to determine the number of credits to be awarded. 4. Any non-certified timber used in the development comes from a legal source and is not included on the CITES list (see definition for legally sourced timber). Exemplary level criteria The following outlines the exemplary level criteria to achieve an innovation credit for this BREEAM issue: 1. Where, in addition to the above criteria, 95% of the applicable materials, comprised within the applicable building elements, have been responsibly sourced. Compliance Notes New Build Refurbishment Extensions to existing buildings Building element not present Reused in-situ materials Specified reused Materials Insulating materials CITES list A Government licence Pre or post consumer waste There are no additional or different criteria to those outlined above specific to new-build projects. In the case of a refurbishment assess the newly specified applicable and reused materials (reused as defined below). There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. Where an element is not present in a project (e.g. an assessment of a ground floor of a building only and therefore no roof in the scope of the assessment), the points for this/these element(s) will be redistributed by the BREEAM Assessor’s responsible sourcing calculator to reward only the elements being assessed. Materials reused in-situ can be excluded from the assessment. The aim of this issue is to focus on the responsible sourcing of new specified materials. Reused materials specified for the development e.g. recycled aggregates are considered equivalent to materials covered by certification schemes that fall within tier 1 of Table 13 Responsible Sourcing Tier Levels and CriteriaTable 13 Responsible Sourcing Tier Levels and Criteria. The responsible souring of materials used for insulating the building fabric and services is assessed as part of BREEAM Materials section issue Mat 6 Insulation (see below). Therefore insulating materials are not assessed as part of this assessment issue, but they are still subject to BREEAM’s responsible sourcing requirements. CITES (Convention on International Trade in Endangered Species) Appendices I and II of the CITES list58 illustrate species of timber that are protected outright. Appendix III of the CITES list illustrates species that are protected in at least one country. If a timber species used in the development is on Appendix III it can be included as part of the assessment as long as the timber is not obtained from the country(ies) seeking to protect this species (see Additional Information for further details). A Government licence e.g. UK Forestry Commission felling licence certificate, does not comply as a third party timber certification scheme for this credit, but can be used as evidence of legally sourced timber. Where materials being assessed (including timber) are part of a pre- or postconsumer waste stream, the EMS sections of the credit can be applied for; however, using an EMS scheme (ISO, EMAS etc.) for new timber does not demonstrate timber certification and therefore does not qualify for any of these BREEAM credits.

For each element, select from the drop down menu the number of different types/specifications of that element you wish to enter and press the select button. If the element is not present select ‘0’. Note: selecting zero will adjust the points required benchmarks accordingly (see below). 3. For each element, select the ‘data type’ from the relevant drop down menu. There are two options depending on the element type, ‘Volume’ or ‘Percentage’. Volume a. For all present elements and element type/specifications, enter the names of the material types comprising each individual type/specification in the relevant cell of the column material types. b. Enter the volume of each individual material type in the relevant cell of the column titled percentage/volume of relevant materials present. c. Enter the total combined volume of the material types in the cell total volume of element present. d. Enter the volume of each material that complies with either tier 1, 2a or b, 3 or 4, as appropriate. At least 80% of the total volume of each type must comply with one or more of the tiers to achieve any points for that element type. Percentage a. For all present elements and element type/specifications, enter the names of the material types comprising each individual type/specification in the relevant cell of the column material types. b. Enter the percentage of each individual material type (as a percentage of the whole element type) in the relevant cell of the column titled percentage/volume of relevant materials present. c. Enter the percentage of each material (as a percentage of the whole element type) that complies with either tier 1, 2a or b, 3 or 4, as appropriate. At least 80% of the materials that make up an element type must comply with one or more of the tiers to achieve any points for that element type. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 176 Mat 5 Responsible sourcing of materials BREEAM Prisons 2008 Combination a. For each type/specification of an element data must be entered by volume or percentage. However, it is not necessary to enter all the data using only one of either volume or percentage, for example one type of an element can be entered using volume and another type using percentage (according to how the relevant building information is sourced/provided). Percentage material breakdown for Green Guide specifications available via the online responsible sourcing calculator BRE Global can, via the online Responsible Sourcing Calculator, provide Licensed BREEAM Assessors with a percentage breakdown of materials for any elemental specification with a Green Guide rating. Assessors can use the online tool to determine the percentage breakdown in two ways; either by entering an individual Green Guide element number for the required specification (if known) or doing a search by building and element type using the relevant drop down menus and elemental specification details provided by the design team. The Assessor must then take the returned data and enter it in to the Mat 5 & 8 calculator tool in accordance with the procedure described above for percentage data entry. The BREEAM Assessor must reference in their Certification report the Green Guide element number for any data sourced from the online Responsible Sourcing Calculator. The online Responsible Sourcing Calculator can be accessed by Licensed BREEAM Assessors via the BREEAM Assessor’s Extranet (there is also a link to the online calculator in the Assessor’s Mat 5&8 calculator tool). 4. Once all data has been entered correctly and in compliance with the criteria, the tool will calculate the total number of points achieved and translate this into the number of credits awarded, as follows: The following scale is used to award credits for new builds and major refurbishment projects: a. ≥15 points 3 credits awarded b. ≥10 points 2 credits awarded c. ≥5 points 1 credit awarded Assessors Calculation procedure: Post Construction/Post Fit Out stage The procedure for calculating the number of credits achieved at the interim and final stages of assessment is the same; however at the final stage of assessment Assessors will need to: 1. Check that the As Built construction matches that proposed at design stage (see Schedule of Evidence). Where there are any differences in the specification, obtain the relevant volumes and/ or percentages of materials for each element that differs. 2. Obtain the relevant confirmation of tier level achieved (see Schedule of Evidence) for all materials, from all sources/suppliers. 3. Confirm and/or re-assign tier levels to each material based on the level of certification provided (see Table 13 Responsible Sourcing Tier Levels and Criteria and Information Required to Demonstrate Compliance). 4. Adjust the Mat 5 & 8 Responsible Sourcing Calculator accordingly to include any revised information/data, following the calculation procedures described above.

Although only 80% of the materials in an element have to be assessed, it may be beneficial to include even small percentages of materials that are in tiers higher than those for the 80% compliant materials, as this will contribute to the total amount of points achieved. A maximum of three points is achievable for each element; therefore for example, where there are two types/specifications for an individual element, each individual type can contribute up to a maximum of 1.5 points. Likewise, if there are four types, each can contribute up to a maximum of 0.75 points (the maximum points achievable is based on 80% of the applicable materials achieving tier 1 certification status).

Where evidence cannot be provided to demonstrate legal sourcing for any element, no points can be awarded for the Responsible Sourcing Issue. 4 Where cement and aggregate, or dry mix concrete are mixed on site, (i.e. not concrete previously certified as pre–cast concrete products or wet ready mix concrete), certification must cover the manufacture of the cement as the primary process, and the extraction of the aggregate and limestone used to make the cement as the supply chain process. * Performance ratings for schemes compliant with BES6001:2008 (or similar) can only be used to demonstrate compliance with the assessment criteria for this issue where certification covers the key process and supply chain processes for the material being assessed. ** In BES6001:2008 to achieve a ‘Pass’, level ‘a’ must, as a minimum, be achieved for clauses 3.3.1, 3.3.2 and 3.3.3. Under clause 3.3.2 level ‘a’ requires a documented EMS system following the principles of ISO14001, but not formal certification. To achieve higher ratings such as ‘Good’, ‘Very Good’ and Excellent a minimum number of points from a combination of clauses 3.3.1, 3.3.2 and 3.3.3 must be achieved. It is possible therefore to get a ‘Good’ or ‘Very good’ rating by only complying with level ‘a’ for clause 3.3.2 and levels ‘c’ and ‘d’ for the other two clauses without necessarily having in place a formal independently certified EMS (as required above). In conducting BES6001 assessment, if the assessor confirms full compliance with clause 3.3.2 level ‘a’ the requirement for an independently certified EMS has been met.

The PEFC endorsement only covers certificates issued against the latest MTCC scheme documents, it must be stressed therefore that any holders of certifications against the previous MTCC scheme documents, including the forest management standard MC&I 2001 or any parts thereof, are NOT PEFC endorsed and this timber must still be classified as Tier 3. When seeking the higher tier level for MTCC certified timber the assessor will need to verify the above via the scope of the supplier’s certificate.

A timber product with 50% recycled timber and 50% legally sourced timber will not comply with the criteria and will not be awarded any points. Using an EMS for new timber does not demonstrate timber certification and therefore does not qualify for points. Chain of Custody This is a process used to maintain and document the chronological history of the evidence/path for products from forests to consumers. Wood must be tracked from the certified forest to the finished product. All the steps, from transporting wood from the forest to a sawmill, until it reaches the customer, must maintain adequate inventory control systems that allow for separation and identification of the certified product. Chain-of-custody certification ensures that a facility has procedures in place to track wood from certified forests and avoid confusing it with non-certified wood. Chain-of-custody is established and audited according to relevant forest certification systems rules.

Each Party to the Convention must designate one or more Management Authorities in charge of administering that licensing system and one or more Scientific Authorities to advise them on the effects of trade on the status of the species. The species covered by CITES are listed in three Appendices, according to the degree of protection they need. 1. Appendix I includes species threatened with extinction. Trade in specimens of these species is permitted only in exceptional circumstances. 2. Appendix II includes species not necessarily threatened with extinction, but in which trade must be controlled in order to avoid utilization incompatible with their survival. 3. Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling the trade.’’ Calculation of Timber Volumes a. Most of the information on areas, lengths and volumes of timber will be available from the component manufacturers or estimator, who should provide a detailed breakdown of quantities of materials.

In order to calculate the volume of wood in timber frame windows, the total length of frame must be obtained. This can then be converted to a volume by multiplying the length of frame on fixed windows by 0.00653 and the length of frame on opening windows by 0.01089. c. In order to calculate the volume of timber in composite timber doors such as a flush door, calculate the total area of all doors summed over the whole building and multiply this by 0.02187 (this factor gives the total volume of timber in the doors and frames). BES 6001:2008 Framework Standard for Responsible Sourcing of Construction Products BES 6001:2008 is a BRE Global standard that provides a framework for the assessment of responsible sourcing schemes and provides a route to certification of construction products. The framework comprises a number of criteria setting out the criteria of an organisation in managing the supply of construction products in accordance with a set of agreed principles of sustainability. To comply with the standard a product must meet a number of mandatory criteria, where a product demonstrates compliance beyond the mandatory levels, higher levels of performance can be achieved. The standard's performance ratings range from Pass to Good, Very Good and Excellent. The development of this standard and subsequent certification schemes will, it is envisaged, provide construction products, not wholly covered under current recognised standards, a means for demonstrating their responsibly sourced credentials. In turn this will allow clients, developers and design teams to specify responsibly sourced construction products with greater assurance and provide a means of demonstrating compliance with the assessment criteria for this BREEAM issue.

Resin based composites such as GRP and polymeric render and timber composites such as Chipboard/Particleboard, MDF, OSB, plywood, hardboard, laminated veneered lumber, glulam and cement bonded particleboard are all required to be assessed for responsible sourcing. Frame: The frame is any of the main structural elements that are not included in the roof, external walls and floors. For example, timber or metal studwork within a plasterboard partition would be included within the internal walls, and timber joists would be included within the floor construction. Where a concrete or steel frame is used, this would be treated as the Frame as it would not be integral to the internal walls for example. Green Dragon Environmental Standard ® (Safon Amgylcheddol Y Ddraig Werdd ®): A stepped standard used to accredit compliance with the Green Dragon Environmental Management Scheme. Dependant on the content of the EMS being assessed, a Level of 1, 2, 3, 4 or 5 may be achieved. At level 4 and above, the Green Dragon Environmental Standard ® can be used as evidence of a compliant EMS for small companies being considered under the assessment of this BREEAM issue. www.greendragonems.com Green Guide Element Number: See Mat 1. Key Processes: the final major aspects of processing that are carried out. There may be a single process or multiple processes requiring assessment, depending on the end product.

Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Mat 5 Responsible sourcing of materials 183 Legally Sourced Timber: BREEAM follows the UK Government's definition of legally sourced timber, as outlined in the CPET 2nd Edition report on UK Government Timber Procurement Policy60, which states that legal timber and wood derived products are those which originate from a forest where the following criteria are met: 1. The forest owner/manager holds legal use rights to the forest. 2. There is compliance by both the forest management organisation and any contractors with local and national legal criteria including those relevant to: a. b. c. d. e. Forest management Environment Labour and welfare Health & safety Other parties’ tenure and use rights 3. All relevant royalties and taxes are paid. 4. There is compliance with the criteria of CITES. Relevant documentation demonstrating the above must be provided or made available on request subject to the availability of such materials in the country concerned. Certification from any of the timber certification schemes identified in tiers 1, 2 and 4 for this credit demonstrate legally sourced timber. Mat 5 & 8 Responsible Sourcing Calculator: The spreadsheet based calculator tool used by the BREEAM Assessor to determine the number of BREEAM credits achieved for the Mat 5 assessment issue (and in the case of the BREEAM Multi-Residential scheme, the Mat 8 assessment issue). Online Responsible Sourcing Calculator: A web based calculator tool for determining the percentage breakdown of materials that comprise a specific building elemental specification e.g. an external wall. Data is available for all elemental specifications that have a Green Guide rating. The calculator is available to Licensed BREEAM Assessors via the Assessor’s online Extranet. Pre-consumer waste stream: Waste material generated during manufacturing processes. Excluded is reutilisation of materials such as rework, regrind or scrap generated in a process and capable of being reclaimed within the same process that generated it. Post-consumer waste stream: Waste material generated by households or by commercial, industrial and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose. This includes returns of material from the distribution chain. Responsible Sourcing: Demonstrated through auditable third party certification schemes. Reused materials: Materials that can be extracted from the waste stream and used again without further processing, or with only minor processing, that does not alter the nature of the material (e.g. cleaning, cutting, fixing to other materials). Recycled Material: Materials diverted from the pre-consumer and/or post-consumer waste streams that require significant processing before they can be used again. For further information please see Calculating and declaring recycled content in construction products, “Rules of Thumb” Guide (WRAP, 2008) www.wrap.org.uk/wrap_corporate/news/wraps_rules_of.html. Supply Chain EMS: covers all of the major aspects of processing and extraction involved in the supply chain for the end product. Note that recycled materials are not required to demonstrate a Supply Chain EMS. If EMS certification is provided for the Key Processes for recycled materials, this is assumed by default. Small Company: A company is defined as ‘small’ if it satisfies at least two of the following criteria: a. A turnover of not more than £5.6 million; b. 50 employees or fewer.

Assessment Criteria The following demonstrates compliance: 1. Any new insulation specified for use within the following building elements must be assessed: • • • • External walls Ground floor Roof Building services First credit - Embodied Impact 2. The Green Guide rating for the thermal insulation materials must be determined. Green Guide ratings for thermal insulation can be found at: www.thegreenguide.org.uk (please refer to the Compliance Notes for guidance where specific insulation has been assessed within an element for the Mat 1 BREEAM issues). 3. Where the Insulation Index for the building insulation is the same as or greater than 2. 4. The Insulation Index is calculated using the Mat 6 Insulation Index Calculator Tool in the BREEAM assessor’s spreadsheet tool. For each type of thermal insulation used in the relevant building elements, the volume weighted thermal resistance provided by each type of insulation is calculated as follows: a. (Area of insulation (m2) * thickness(m)) / Thermal Conductivity (W/ m.K) OR b. Total volume of insulation used (m3) / Thermal conductivity (W/m.K) The volume weighted thermal resistance for each insulation material is then multiplied by the relevant Green Guide point(s) from the following table: Table 15 Green Guide rating points/element Green Guide Rating Points/element A+ 3 A 2 B 1 C 0.5 D 0.25 E 0 SD5054 issue 4.1 Uncontrolled copy if printed.

Extensions to existing buildings If the building is part refurbishment part new-build extension then the whole building must be used to determine compliance with this issue. For assessments of extensions to existing buildings, where only the extension is being assessed, it is the extension only that must comply. Predemolition/prerefurbishment audit A pre-demolition/pre-refurbishment audit should be carried out using an appropriate methodology. At the time of writing BRE are currently developing a tool as part of the SMARTWaste system for carrying out such audits, and the ICE has produced guidance on pre-demolition audits, including ‘A report on the Demolition Protocol’62. Since April 2008 any construction project in England costing over £300k requires a Site Waste Management Plan. To achieve any of the construction site waste management credits the assessed development, regardless of value or locality, must have a SWMP compliant with best practice (see relevant definitions in additional guidance section). Where space on site is too limited to allow waste materials to be segregated, a waste contractor may be used to separate and process recyclable materials off site. Similarly, manufacturers’ take-back schemes could also be used. Where this is the case, sufficient documentary evidence must be produced which demonstrates that segregation of materials is carried out to the agreed levels and that materials are reused/recycled as appropriate.

In some circumstances, depending on the size of the building, site restrictions or tenancy arrangements, it may not be possible to meet a 20m requirement. If it is the opinion of the assessor that it is not feasible to meet this 20m requirement then they can use their judgement to determine if the facility is in an easily accessible location for building occupants and vehicle collection and to state their reasons in the assessment report. Individual recycling bins located at convenient locations throughout the building are necessary to maximise recycling rates. On their own, however, these are not sufficient to obtain this credit. Where the facilities are situated internally, vehicular gate heights/widths and manoeuvring and loading space must be sized correctly to ensure ease of access for vehicles collecting recyclable materials. The area for recyclable materials storage must be provided in addition to areas and facilities provided for dealing with general waste and other waste management facilities, e.g. compactors and balers.

Additional Information Relevant Definitions Clinical Waste: Waste derived from medical practices and defined as bodily fluids and wastes, drugs and medical equipment; and other waste which, unless rendered safe, may prove hazardous or infectious to persons coming into contact with it. The following footprint dimensions can act as a guide when determining size and accessibility criteria for the recyclable storage space: • • • • • Compactor dimensions: about the size of one car parking bay; 4.8 x 2.4m Skip: The footprint of an 8 and 12 cubic yard skip measures 3.4m x 1.8m, therefore allow a minimum of 2.0m width and 4.0m length or 8m2 area for the storage and access of such containers Wheeled bins: 360 litre = 0.86m x 0.62 / 660L= 1.2m x 0.7m / 1100L = 1.28m x 0.98m Roll-on-roll-off containers: allow a minimum of 6.1m x 2.4m. Vehicle access: The following are dimensions for lorry types that are typically used to collect waste. Therefore gate height/widths should not be smaller than these measurements: o Dustcart: medium capacity; length = 7.4m Height = 4m width 3.1m o Skip lorry: length = 7m Height = 3.35m width 3.1m Consideration must also be given to any other types of vehicle requiring access to this area, e.g. lorries for roll on/off containers.

The requirement to achieve the credit for storage of recyclable materials is set in order to encourage the minimisation of the assessed development’s waste streams by encouraging a more integrated approach to the issue of waste management, recycling and disposal. The provision of adequate recycling and waste management facilities helps to ensure that this objective can be achieved. Compacting dry waste can significantly reduce the volume of waste sent to landfill. Furthermore, whether for recycling or landfill, compacting waste at source will reduce the number of trips required for the collection and delivery of the waste and therefore result in reduced fuel consumption and vehicle emissions. Reduced vehicle movements will also provided social and health & wellbeing benefits to the surrounding community and economic benefits to the building occupier.

The definition includes: a. Defence buildings The definition excludes: a. Land that is or has been occupied by agricultural or forestry buildings. b. Land that has been developed for minerals extraction or waste disposal by landfill purposes where provision for restoration has been made through development control procedures. c. Land in built-up areas such as parks, recreation grounds and allotments which, although may feature paths, pavilions and other buildings, have not been previously developed. d.

Extensions to existing buildings There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. Prior Decontamination The credit can only be awarded where remediation has taken place to enable current development of the site for the assessed building, or part of a larger phased development that includes the assessed building (see below). The credit is not achievable for instances where historical remediation and development of the site has occurred outside the scope of the current development proposals. Where a large site has been decontaminated and is then packaged up into smaller plots of land for individual buildings (possibly as part of a phased development strategy), the credit can be awarded regardless of the plot location of the assessed building. This is on the condition that the whole site could not have been developed without remediation work taking place. Contaminated land that has been decontaminated solely for health and safety reasons (rather than for the specific purpose of re-development) does not comply. Large sites split into smaller plots Health and Safetyrelated decontamination Asbestos Where the only decontamination required is for the removal of asbestos within an existing building fabric, this cannot be classified as contaminated land.

Additional Information Relevant definitions Contaminant: Is defined as any solid, liquid or gaseous material in, or on the ground to be covered by the building, which is classed as a hazard and therefore presents an unacceptable risk to human health and the environment. The definition also includes land significantly infested by non-native invasive plant species (see below). Significant contamination: For the purposes of this issue, significant contamination is contamination compliant with the above and that, without remediation, development of the site is not possible. Remediation: Activity undertaken to prevent, minimise, remedy or mitigate the risk caused by contaminated land to human health or the environment. Non-native invasive plant species: Are non-indigenous species that adversely affect the habitats they invade economically, environmentally or ecologically. For the purposes of BREEAM this currently includes Japanese Knotweed and Giant Hogweed only.

Assessment Criteria The following demonstrates compliance: 1. Land within the construction zone is defined as ‘land of low ecological value’ using either: a. BREEAM checklist A4 OR b. A suitably qualified ecologist who has identified the land as being of ‘low ecological value’ within an ecological assessment report, based on a site survey. 2. All existing features of ecological value surrounding the construction zone and site boundary area are adequately protected from damage during clearance, site preparation and construction activities as listed below: • • • • Trees of over 100 mm trunk diameter, and/or of significant ecological value, are protected by barriers. Barriers must prohibit construction works in the area between itself and the tree trunk. Minimum distance between tree trunk and barriers must be either the distance of branch spread or half tree height, whichever is the greater. In all cases trees must be protected from direct impact and from severance or asphyxiation of the roots. Hedges and natural areas requiring protection must either have barriers erected and be protected, or, when remote from site works or storage areas, be protected with a prohibition of construction activity in their vicinity. Watercourses and wetland areas are to be protected by cut-off ditches and site drainage to prevent run-off to natural watercourses (as this may cause pollution, silting or erosion). 3. In all cases, the contractor is required to construct ecological protection prior to any preliminary site construction or preparation works (e.g. clearing of the site or erection of temporary site facilities). Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new build projects. Refurbishment A refurbishment of a building (with no new construction), must protect any existing ecological features of value. Protection includes clear exclusion procedures for construction traffic/personnel and material storage, as well as physical barriers. Extensions to Where a refurbishment includes new building work or infrastructure, the land existing on which the new build area and its associated infrastructure (e.g. roads, buildings pavements, car parks etc) will be situated, must comply with the criteria.

Valid on day of printing only © BRE Global Ltd 2012 210 LE3 Ecological value of site and protection of ecological features No features of ecological value Use of a suitably qualified ecologist Features of little or no ecological value Removal of features of ecological value Site clearance prior to purchase of the site BREEAM Prisons 2008 Where the construction zone is defined as ‘land of low ecological value’ and where the surrounding site contains no features of ecological value, this credit can be awarded. Where a suitably qualified ecologist is employed and has, using their professional judgement, defined the site as land of low ecological value, this assessment/judgement overrides any assessment determined using checklist A4. The suitably qualified ecologist must base their findings on data collected from a site visit conducted at appropriate time(s) of the year, when different plant and animal species are evident. The content of the Ecology Report is to be representative of the existing site’s ecology prior to the commencement of initial site preparation works (i.e. before RIBA stage K, construction to practical completion). Where the ecologist has made no on-site visit, the credit cannot be awarded. See additional guidance for definition of a suitably qualified ecologist. If a suitably qualified ecologist has confirmed that a feature has little or no ecological value, or where a tree is deemed to create a significant danger to the public or occupants by a statutory body or qualified arboriculturalist, then that feature may be exempt from the protection of ecological features requirement of this issue. If features of ecological value have been removed as part of site clearance then the development cannot achieve this credit, even if they are to be replaced as part of a new landscaping strategy. For sites that have been cleared more than five years ago, the ecological value of the site would be its present ecological value, on the basis that in the intervening five years, ecological features would have started to re-establish themselves and therefore act as an indicator of the site’s ecological value. For sites that have been cleared less than five years before assessment, a suitably qualified ecologist should make an estimation of the site’s ecological value immediately prior to clearance on the basis of available desktop information (including aerial photography) and the landscape type/area surrounding the site. Where it is not possible for the ecologists to determine that the site was of low ecological value prior to the site clearance then the credit must be withheld. Schedule of Evidence Required Req.

Additional Information Relevant definitions Construction zone: For the purpose of this BREEAM issue the construction zone is defined as any land on the site which is being developed (and therefore disturbed) for buildings, hard standing, landscaping, site access, plus a 3m boundary in either direction around these areas. It also includes any areas used for temporary site storage and buildings. If it is not known exactly where buildings, hard standing, site access and temporary storage will be located it must be assumed that the construction zone is the entire site. Suitably qualified ecologist (SQE): An individual achieving all the following items can be considered to be “suitably qualified” for the purposes of a BREEAM assessment: 1. Holds a degree or equivalent qualification (e.g. N/SVQ level 5) in ecology or a related subject. 2. Is a practising ecologist, with a minimum of three years relevant experience (within the last five years). Such experience must clearly demonstrate a practical understanding of factors affecting ecology in relation to construction and the built environment; including, acting in an advisory capacity to provide recommendations for ecological protection, enhancement and mitigation measures. Examples of relevant experience are: ecological impact assessments; Phase 1 and 2 habitat surveys and habitat restoration. 3. Is covered by a professional code of conduct and subject to peer review. Peer review: Is defined as the process employed by a professional body to demonstrate that potential or current full members maintain a standard of knowledge and experience required to ensure compliance with a code of conduct and professional ethics.

Assessment Criteria The following demonstrates compliance: 1. One credit where the change in ecological value of the site is less than zero and equal to or greater than minus nine plant species i.e. a minimal change. 2. Two credits where the change in ecological value of the site is equal to or greater than zero plant species i.e. no negative change. The change in ecological value of the site is calculated using EITHER of the following: 3. Determine the following information and input this data in to Ecology calculator 1 within the spreadsheet tool: a. Plot type(s) that define the landscape of the assessed site, in its existing pre-developed state and proposed state (see additional guidance) b. Areas (m2) of the defined existing and proposed plot types. OR 4. Where a suitably qualified ecologist has been appointed and, based on a site survey, they confirm the following and the assessor or ecologist inputs this data in to the Ecology calculator 2: a. Actual plot/habitat types that define the landscape of the assessed site in its existing predeveloped state and proposed state b. Area (m2) of each plot/habitat type c. Number of different plant species found within each plot type. Compliance Notes New Build Refurbishment Extensions to existing buildings There are no additional or different criteria to those outlined above specific to new build projects. There are no additional or different criteria to those outlined above specific to refurbishment projects. There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. Refer also to the note below on infill developments. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 214 LE4 Mitigating ecological impact Completing Ecology Calculator 1 BREEAM Prisons 2008 First, define the landscape type (based on the typology of the surrounding sites, Table 18 General Landscape Types). This category is unlikely to change through the development, although it may in some cases, e.g. when a disused site is developed as part of a master plan for a large multi-use or multi-building development/regeneration project. Then, define and calculate the area (m2) of each vegetation-plot type ( Table 19 Vegetation Plot Types) and building or hard landscaped area, both before and after development, for the site. Once the data is entered, the Ecology Calculator 1 will indicate the indicative change in ecological value. The result must be used to award the credits. Number of plant species BREEAM measures ecological value using number of plant species. The plant species figures for each land type are programmed into the Ecology Calculator tool 1. These figures are based on national figures from the Countryside Survey prepared for the Digest of Environmental Statistics64 (see Table 20 Number of plant species by plot for different landscape types). Where an ecologist has been appointed actual number of plant species (before and after construction), based on the ecologists site survey should be used to determine the change in ecological value. Wildlife garden planting In the ‘change of ecological value’ table, ‘garden planting (typical)’ and ‘wildlife garden planting’ will always record a score of zero, unless a suitably qualified ecologist has been appointed: whereby they will make the distinction between ‘typical’ and ‘wildlife’ garden planting species and record ‘actual’ species numbers. Derelict Sites The ecological value of derelict sites is time dependent (Table 20 Number of plant species by plot for different landscape types); a linear scale has been used to determine intermediate values between zero ecological value at 1 year from dereliction/demolition to a value at 30 years based on marginal upland figures. This presents a worst case figure which can be amended on the advice of a suitably qualified ecologist. Assessment of a single development on a larger site Where the assessment is of a single building that forms part of a larger site development and the landscaping and ecological features form a common part of the whole site, for the purpose of assessing this issue the plot types and areas for the entire site must be used. Infill developments on existing occupied site Site clearance prior to purchase of the site Green Roofs Where a development is an infill (or new building) on an existing occupied site, then the construction zone for the new building would be the area of site assessed for the purposes of this issue. Refer to the compliance note in LE3 on this issue. The contribution of species from a Green roof can only be incorporated where a suitably qualified ecologist has been appointed.

Arable Land dominated by cereals and other arable crops, as well as intensively managed grasslands. Marginal Upland Areas which are on the periphery of the uplands, and which are dominated by mixtures of low intensity agriculture, forestry and seminatural vegetation. Upland Land generally above a height suitable for mechanised farming and frequently dominated by semi-natural vegetation. Building & Derelict Land Land currently or previously occupied by buildings. Urban Mosaic A complex mix of habitats located within cities, towns, or villages, which will include; buildings, hard standing, pockets of disused land and scrub, and areas of managed green spaces, such as gardens, allotments, and parkland. Parklands can be characterised as being accessible to the public and will usually be fairly intensively managed spaces, consisting of a matrix of grassland (grazed or mown) with scattered trees at various densities and areas of dense planting. This landscape type is to be used only when no other landscape type in the table is more appropriate / predominates. Table 19 Vegetation Plot Types Crops/weeds Mostly highly disturbed vegetation of arable fields and their boundaries; includes cereal and vegetable crops. Tall grassland/herb Typical vegetation of overgrown lowland field boundaries, ditches and roadside verges. Fertile grass The bulk of agriculturally improved grasslands, intensive pasture and silage crops; but also includes mown areas of improved grasslands for recreational and amenity purposes, as well as re-sown roadside verges. Infertile grass A diverse group of semi-improved and semi-natural grasslands; includes acidic to basic, wet to dry grasslands, and tall-herb vegetation mainly present in the lowlands; often found on stream sides and roadside verges. Lowland wooded Includes wooded vegetation of hedges and broadleaved woods in the lowlands. Upland wooded A varied group of acidic vegetation types usually associated with upland woods, including: semi-natural woodland; conifer plantations; bracken and wooded streamsides. Moorland grass/mosaic Typically grazed moorland vegetation, including extensive upland acidic and peaty grassland, and species-rich but very localised flushes. Heath/bog Mostly heather moorland, blanket bog and montane heath, but also lowland heath and raised bog. Wildlife garden planting Garden planting that uses native species and/or those that have a known attraction or benefit to local fauna, based on the advice of a suitably qualified ecologist.

Valid on day of printing only © BRE Global Ltd 2012 218 LE4 Mitigating ecological impact BREEAM Prisons 2008 Calculating the change and increase in ecological value BREEAM calculates the change in ecological value by comparing the diversity (number and area) of plant species on the site pre and post construction. The ecological value of the site is expressed as an area-weighted average of plant species for the site’s landscape type. This enables BREEAM to use this as an indicator of the proposed development’s impact on the site’s existing ecological value. A simple example of the calculation is outlined below. 1. Calculate the ecological value of a previously developed existing site: A 2065m2 existing site consists of the following types of land: a. 1865 m2 hard landscaping = 0 species b. 200m2 urban mosaic - infertile grassland = 17.6 species (Table 20 Number of plant species by plot for different landscape types). The ecological value of the existing site is calculated as follows, for each plot type; • Number of species on plot type x plot type area as % of total area. Therefore, for our example site: a. Hard landscaping: {(0 species x (1865m2/2065m2)} = 0 species b. urban mosaic-infertile grassland: {(17.6 species x (200m2/2065m2)} = 1.70 species c. Ecological value of the existing site = 0 + 1.70 = 1.70 species 2. Calculate the ecological value of the proposed site: The 2065m2 post-construction site consists of the following types of land: a. 1375m2 of building = 0 species. b. 550m2 of hard landscaping = 0 species c. 140 m2 has remained as urban mosaic-infertile grassland = 17.6 species The ecological value of the proposed site is as follows: a. b. c. d. Building: {(0 species x (1375m2/2065m2)} = 0 species Hard landscaping: {(0 species x (550m2/2065m2)} = 0 species Urban mosaic-infertile grassland: {(17.6 species x (140m2/2065m2)} = 1.19 species Ecological value of the proposed site = 0 + 0 + 1.19 = 1.19 species The ecological impact is the difference between the two ecological values: Change in ecological value: 1.19 – 1.70 = - 0.51 species Therefore, for this example 1 credit is achieved.

Compliance Notes New Build & Refurbishment on existing prison sites Extensions to existing buildings Timing of Ecologist Report General recommendations Guidance for ecologists and assessors For assessments of new buildings on existing prison sites, where it is not possible to implement ecological enhancements within the construction zone due to security concerns, ecological enhancement to other areas of the site can be taken into account. There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. It is recommended that the suitably qualified ecologist is appointed to carry out site surveys of existing site ecology, on which their report is based, or to provide verification where the report is prepared by others, at the design brief stage (RIBA Stage B or equivalent) in order to facilitate and maximise potential ecological enhancement. ‘General’ recommendations for enhancing and protecting the ecological value of the site are to include, and go beyond, compliance criteria for all current EU and UK legislation relating to protected species and habitats. These ‘general’ recommendations may include ecological recommendations as detailed in the definitions.

Assessment Criteria The following demonstrates compliance: One credit can be awarded where there is a commitment to achieve the mandatory criteria and at least two of the additional criteria (listed below). Two credits can be awarded where there is a commitment to achieve the mandatory criteria and at least three of the additional criteria (listed below). Three credits can be awarded where there is a commitment to achieve the mandatory criteria and at least four of the additional criteria (listed below). Mandatory Criteria 1. A suitably qualified ecologist (SQE) has been appointed prior to commencement of activities on site. 2. The suitably qualified ecologist confirms that all relevant UK and EU legislation relating to protection and enhancement of ecology has been complied with during the design and construction process. 3. A landscape and habitat management plan, appropriate to the site, is produced covering at least the first five years after project completion. This is to be handed over to the building occupants and includes: • Management of any protected features on site • Management of any new, existing or enhanced habitats • A reference to the current or future site level or local Biodiversity Action Plan. Additional Criteria 1. The contractor nominates a ‘Biodiversity Champion’ with the authority to influence site activities and ensure that detrimental impacts on site biodiversity are minimised in line with the recommendations of a suitably qualified ecologist. 2. The contractor trains the site workforce on how to protect site ecology during the project. Specific training should be carried out for the entire site workforce to ensure they are aware of how to avoid damaging site ecology. Training should be based on the findings and recommendations for protection of ecological features highlighted within a report prepared by a suitably qualified ecologist. 3. The contractor records actions taken to protect biodiversity and monitor their effectiveness throughout key stages of construction. The requirement commits the contractor to make such records available where publicly requested. SD5054 issue 4.1 Uncontrolled copy if printed.

Where a new ecologically valuable habitat, appropriate to the local area, is created. This includes habitat that supports nationally, regionally or locally important biodiversity, and/or which is nationally, regionally or locally important itself; including any habitat listed in the UK Biodiversity Action Plan (UK BAP)65, Local Biodiversity Action Plan (LBAP), those protected within statutory sites (e.g. SSSIs), or those within non-statutory sites identified in local plans. 5. Where flora and/or fauna habitats exist on site, the contractor programmes site works to minimise disturbance to wildlife. For example, site preparation, ground works, and landscaping have been, or will be, scheduled at an appropriate time of year to minimise disturbance to wildlife. Timing of works may have a significant impact on, for example, breeding birds, flowering plants, seed germination, amphibians etc. Actions such as phased clearance of vegetation may help to mitigate ecological impacts. This additional requirement will be achieved where a clear plan has been produced detailing how activities will be timed to avoid any impact on site biodiversity in line with the recommendations of a suitably qualified ecologist. Compliance Notes New Build Refurbishment Extensions to existing buildings Refurbishment of listed buildings Biodiversity Champion Local biodiversity expertise The site and surrounding areas Sites of no ecological value There are no additional or different criteria to those outlined above specific to new build projects. There are no additional or different criteria to those outlined above specific to the assessment of refurbished buildings (unless the building is listed – see below). There are no additional or different criteria to those outlined above specific to the assessment of extensions to existing buildings. The refurbishment of a listed building may be exempt from the assessment criteria if they conflict with the need to maintain the building’s listed features, or are counter to the conservation criteria. Confirmation is required from a suitably qualified ecologist that all possible criteria/enhancements have been achieved before the credit can be awarded (i.e. if no suitably qualified ecologist has been appointed then this credit cannot be awarded). A Biodiversity Champion does not have to be an ecologist or ecological expert but must have sufficient authority and time on site to influence activities and ensure that they have minimal detrimental impact on biodiversity. Local biodiversity expertise should be sought at, or before, the design stage to help identify species of local biodiversity importance on site. It is likely that their recommendations will draw on the Local Biodiversity Action Plan (LBAP) where one exists. The steps taken in the above criteria will depend on the nature of the site, e.g. urban sites, and the surrounding areas. It is likely that either all, or none, of the optional items will apply. Where the optional items and the mandatory item 3, the management plan, are deemed, in writing, by the appointed suitably qualified ecologist not to be applicable, all credits can be awarded. Mandatory items 1 and 2 must be met in all instances. This is likely to be the case in the majority of assessments in central town/city areas which have a high proportion of surrounding and existing development and no existing external landscaped areas within the boundary of the assessed site. Where a site is deemed to have no ecological value, it is still necessary to employ a suitably qualified ecologist to achieve this credit. The ecologist must confirm that all the mandatory items (1), (2) and (3) have been achieved and provide guidance on how to achieve optional item (4). Note that in such cases, mandatory item (1) and additional requirement (4) is likely to be applicable in relation to any ecological enhancements (e.g. green roofs, bird boxes, etc.) adopted in order to achieve the Enhancing Site Ecology issue (LE5).

In this instance the credit cannot be awarded by default as there are alternatives for designers to consider. These alternatives include revisiting the design and the room conditions specification to see if the cooling equipment is necessary. In addition, whilst a manufacturer or supplier may specify a narrow temperature band for server equipment, acceptable limits detailed in ASHRAE guidance67 may allow a greater temperature range without adverse effect and thus the cooling equipment may not be necessary.

Because they do not use a chlorine atom (which is used in most refrigerants) they are known to be one of the least damaging to our ozone. Hydrogenated Chlorofluorocarbon Refrigerants (HCFCs) are made up of hydrogen, chlorine, fluorine, and carbon. These refrigerants contain minimal amounts of chlorine; they are not as detrimental to the environment as some other refrigerants. Chlorofluorocarbon Refrigerants (CFCs) contain chlorine, fluorine and carbon. These refrigerants carry high amounts of chlorine so they are known for being the most hazardous to the ozone layer.

Other published data may be based on different time horizons. • All CFC/HCFC refrigerants (marked *) have an ODP > 0 and as such are illegal for new installations. Existing equipment may continue to use them at present. The use of CFCs and HCFCs as refrigerants has been addressed under the Montreal protocols. Phase out programmes have been agreed resulting in these substances no longer being used as refrigerants in all new build and most existing situations. The industry’s favoured replacements are currently HFCs which are often potent global warming contributors. • Whilst it is currently still legal to have an existing system that uses refrigerants with an ozone depleting potential, it is now illegal to top up with CFCs (either new or recycled refrigerant). It will be illegal to top up with new HCFCs from 2010, and it will be illegal to top up with recycled/recovered HCFCs from 2015. • Hydrocarbons and ammonia-based refrigerants have low or zero GWP and are therefore preferred long-term options. These are now widely available and are valid alternatives to HFCs in all buildings, provided health and safety issues are fully addressed. SD5054 issue 4.1 Uncontrolled copy if printed.

Refrigerant Recovery: The process of removing refrigerant from a system and storing it in an airtight container. Leak detection systems/devices • • • • • • • Handheld detectors (which include semi-conductor and corona discharge types) do not comply with BREEAM criteria. Corona discharge detectors are not suitable where flammable refrigerants are used, or in potentially explosive atmospheres. Indicator dyes: these consist of fluorescent or coloured dyes added to the refrigerant to show leakage sites. The use of the dye should be approved by the compressor manufacturer. Some compressor manufacturers do not approve the use of indicator dyes, in which case either an alternative type of equipment should be used, or an alternative type of leak detection specified. Halide torch detectors: this type of detection is only appropriate for chlorine-based substances such as CFCs and HCFCs, and should not be used in areas where naked flames are prohibited. Compounds which do not contain chlorine, e.g. HFCs, cannot be detected by this method. When awarding this credit in instances where these detectors are in use, the assessor should confirm that the refrigerant is chlorine based. Electronic leak detectors: these must be designed to detect a certain type of, or multiple types of, refrigerant, i.e. CFC, HFC, HCFC, etc. Standing hold test: systems based on monitoring pressure drops within the pipe work are not necessarily compliant with the BREEAM criteria. There are natural fluctuations to the pressure of the refrigerant due to changes in volume and temperature of the system, and to the ambient temperature of the surroundings. Low pressure and high pressure switches, which are standard equipment on refrigerant plant, are therefore not sufficient to award the credit. Other methods exist, such as pressurising the system with a high pressure, dry nitrogen gas for a period of time and then identify whether or not the pressure drops during this time. However, this requires systems to be shut down for a period of time (usually overnight or longer). Systems NOT based on the principle of detecting or measuring the concentration of refrigerant in air: Such systems (for example based on sensing the presence of refrigerant vapour in liquidcarrying pipes) are now commercially available. Refrigerant pump down The specification of automatic refrigerant pump down can further limit potential losses and damage to the environment and have subsequent economic benefits to the building owner. Under the United Kingdom 1990 Environmental Protection Act unwanted refrigerant and refrigerating system oil are classified as either controlled or hazardous waste. Not only is it an offence to discharge them to the environment, but there are procedures regarding transport, storage, transfer of ownership and ultimate disposal. Article 16 of EC regulation 2037/2000 specifies that used CFCs and HCFCs must be recovered for destruction or recycling/reclamation. SD5054 issue 4.1 Uncontrolled copy if printed.

Assessment Criteria The following demonstrates compliance: 1. Where manufacturer’s details demonstrate that the plant installed to meet the building’s space heating demand has dry NOx emission levels as follows: a. One credit where the dry NOx emissions from delivered space heating energy are ≤100 mg/kWh (at 0% excess O2). b.

Three credits where the dry NOx emissions from delivered space heating energy are ≤40 mg/kWh (at 0% excess O2). And emissions from delivered water heating energy are 100 mg/kWh or less (at 0% excess O2). The emissions should be estimated under normal operating conditions (not standby). Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new build projects. Refurbishment If the heating demand for the refurbished building is being met by an existing system, then the NOx emission level for the existing system must be assessed against the criteria of this issue.

This figure is a UK average and therefore also applies to areas/countries with a higher proportion of renewable sources, such as Scotland. Where electricity used by the heating system is sourced from a zero emission renewable source such as PVs, wind etc, there are no resulting emissions. This source of heating can therefore be counted as having zero NOx emissions. Heat pumps powered by grid electricity are likely to indirectly produce emission rates higher than those required by BREEAM and are therefore typically unable to achieve any credits under issue Pol 4. However, there is a formula for determining NOx emissions from heat pumps in the Additional Information section below. Please note, the energy saved by using certain types of heat pumps is recognised in BREEAM issue Ene 1 and the reduced emissions are recognised under BREEAM issue Ene 5. District heating systems that incinerate waste usually have NOx emission rates higher than the levels set to achieve any BREEAM credits. Heat recovery can be considered as having zero NOx emissions for the purpose of this issue. Refer to the additional guidance section for guidance on calculating NOx emission levels from CHP. Whilst Biomass systems are recognised as low carbon systems, they can produce a significant amount of NOX and so may not achieve this credit; however they can score highly in the Energy section of BREEAM. Biomass systems are also recognised as reducing the impact of fossil fuel depletion by employing a renewable combustion fuel source. Refer to the additional guidance section for guidance on calculating NOx emission levels where heat is provided by more than one system. Commitments to use a Green tariff to supply electricity to heat the building or power heat pumps are not recognised in this issue due to the uncertainty that this electricity will be zero emission.

Valid on day of printing only © BRE Global Ltd 2012 and BREEAM Prisons 2008 Pol 4 NO x emissions from heating source 237 NOx emissions: are pollutant gases produced by the combustion of fossil fuels. NOx reacts with heat and sunlight to produce ozone that can cause serious respiratory problems. It also reacts with water to produce acid rain which has a detrimental effect on ecosystems. Dry NOx Levels: the NOx emissions (mg/kWh) resulting from the combustion of a fuel at 0% excess oxygen levels. Calculating NOx emission levels from Combined Heat & Power (CHP) systems Where CHP systems are present or specified, only the heat-related emissions are considered for the assessment of this issue. The NOx emissions are allocated to heat and electricity in line with the respective power outputs. This is done using a NOx emission rate for the electrical output equivalent to the current rate for grid electricity, and allocating the remaining NOx to the heat output. Only the heatrelated component is then compared with the credit scale. The following formula should be used to determine this: X = (A - B) / C Where: X = NOx emissions per unit of heat supplied (mg/kWh heat) A = NOx emissions per unit of electricity generated (mg/kWhelec) i.e. the NOx emitted by the CHP system per unit of electricity generated. This figure should be obtained from the installer/supplier of the system. B = NOx emissions per unit of electricity supplied from the grid (mg/kWhelec) this should be assumed to be 1200mg/kWh C = Heat to Electricity Ratio of the CHP scheme. The above methodology determines the net NOx emissions from CHP-generated electricity compared with central generation of electricity and allocates this amount to the heat production. Where X is calculated to be negative, it should be assumed to be zero. Where heat is provided by more than one system, an average NOx emission rate should be used based on the ratio of power outputs from each source, i.e. multiply the emissions of each boiler by the percentage of heat demand it supplies and total these values. This is likely to be the case where a CHP system has been sized on the base power demand rather than the heat demand and therefore a secondary heating system is required. The following formula can be used: Average NOx Emission Rate = (N1 x (H1/HT)) + (N2 x (H2/HT)) …… + (Nn x (Hn/HT)) Where: N1 = NOx emissions rate for source 1 N2 = NOx emissions rate for source 2 Nn = NOx emissions rate for source n HT = Total heat output from all sources H1 = Heat output from source 1 H2 = Heat output from source 2 Hn = Heat output from source n SD5054 issue 4.1 Uncontrolled copy if printed.

EER Where: MHeat = NOx emission per unit of heat generated in mg/kWhHeat MElec = NOx emissions from UK grid electricity mg/kWh, this should be assumed to be 1200mg/kWhelec W Elect = Total quantity of electricity consumed by heat pump kWhElec W Heat = Total quantity of heat produced by heat pump kWhHeat EER = Energy Efficiency Ratio (also referred to as Co-efficient of Performance) Conversion factors Manufacturers should be asked to supply dry NOx emissions data in mg/kWh. Where this is not possible the assessor may use the following conversion factors to convert figures in ppm, mg/MJ, mg/m3 or wet NOx. It should be noted that these conversion factors assume worst case efficiencies and are likely to give conservative answers. This could have the effect of lowering the number of credits achieved. • Figures in mg/m3 should be multiplied by 0.857 in order to gain emissions in mg/kWh. A conversion may also be necessary for data not calculated at 0% excess oxygen (see below). • Figures in parts per million (ppm) should be multiplied by 1.76 in order to obtain mg/kWh. A conversion may also be necessary for data not calculated at 0% excess oxygen. (see below) • Figures in mg/MJ should be multiplied by 3.6 in order to show emissions in mg/kWh (1 kWh = 3.6 MJ). A conversion may also be necessary for data not calculated at 0% excess oxygen (below). • This Issue’s criteria are based on dry NOx values – almost all manufacturers will quote emissions in dry NOx. However if wet NOX figures are supplied, these should be converted to dry NOx. This can be done by multiplying the wet NOX figure by 1.75. Excess Oxygen Correction: If a NOx emission rate is quoted by the manufacturer in mg/m3 or ppm, then it should be established at what % excess oxygen this emission was measured. The greater the amount of excess oxygen in the flue gases at the time of measurement, the more “diluted” the NOx. It is therefore important to convert any emission rate back to 0% excess oxygen. For the purpose of BREEAM, the following conversion factors can be used for the most frequently used rates supplied by manufacturers: % Excess O2 3% 6% 15% Conversion factor Conversion (c) x 1.17 x 1.40 x 3.54 c = 20.9/(20.9 – x) Where x = % excess O2 (NOT excess air) and 20.9 is the percentage of O2 in the air.

Refurbishment Refurbishment projects, where no new building or hard landscaping areas are developed, are likely to achieve the credit for attenuation of surface water runoff.

Functional flood The BREEAM credit for locating in a flood zone of ‘medium or high annual plain probability’ cannot be awarded where the building is located in the functional flood plain. PPS2573 defines the functional flood plain as a ‘zone [that] comprises land where water has to flow or be stored in times of flood’. If the building assessed is or has been defined as ‘water-compatible development’, please refer to the BREEAM office for guidance on assessing this BREEAM issue. Environment The Environment Agency flood map and associated information is intended for Agency flood guidance, and cannot provide details for individual properties. In addition the maps EA map only covers the likelihood of flooding from the rivers or sea and not all sources of flooding (listed above). EA flood maps cannot therefore be used as evidence to demonstrate compliance with the assessment criteria. Pre-existing flood In an area protected by existing flood defences (designed to withstand a defences certain magnitude of flooding) the appropriate number of credits can be awarded where the defences reduce the risk to ‘low’ or ‘medium’ and the following conditions are met: 1. The development is not located in an area where new flood defences have to be, or have been, constructed to minimise the risk of flooding to the site and its locality purely for the purpose of the development and/or its wider master plan 2. The development is located on a previously developed land (as defined by the criteria in BREEAM issue LE1 Re-use of land) and the appropriate statutory body confirm that, as a result of the existing defences, the risk of a flood event occurring is reduced to low or medium (as appropriate to the credit levels set in BREEAM). If firm confirmation is not provided then the credit cannot be awarded 3. The relevant agency confirms that, as a result of such defences, the risk of a flood event occurring is reduced to low or medium risk. A statutory body’s local/regional office may be able to provide more information on existing defences in the area in which the assessed development is located.

In such cases the credit is still achievable provided safe access to the site and the ground floor of the building can be maintained (i.e. they are 600mm above the design flood level) to ensure the building/site does not become an ‘island’ in the event of a flood. Where the development has been permitted and the ground levels of the topography/infrastructure immediately adjacent to the site fall below the 600mm threshold, the credit can still be awarded, provided there are no other practical solutions for access to the site above this level and the assessed building, and access to it, meets the assessment criteria. As much of the external site area as possible (or as required by an appropriate statutory body) should be designed at or above the threshold. There are many defences, owned by third parties, which due to their location act as a flood defence by default e.g. motorway, railway embankments, walls etc. It can be assumed that embankments will remain in place for the lifetime of the development, unless the assessor or project team have reason to believe otherwise. For walls, assurance must be sought that the wall is likely to remain for the design life of the building. To ensure effective operation of the water run-off attenuation measures, the facilities must discharge half their volume within 24-48 hours (unless advised otherwise by a statutory body) of the storm event in readiness for any subsequent storm inflow. There are British Standards74 & 75 that contain guidance on calculating the peak flow rate and determining the design flooding frequency. The assessor is not required to perform any calculation as this should be provided by the design team to demonstrate that they have sized the attenuation facilities to store the relevant volume of storm water necessary to achieve the credit. If all run-off is discharged directly from the site to either the sea, the foreshore, estuaries covered by a shoreline management plan or designated wildlife/SSSI areas (as part of habitat management) then the credit can be awarded without the need to specify additional attenuation measures. Where the local authority (or other statutory body) requires a greater attenuation than the percentages above, and/or a more onerous design flooding frequency than that recommended in BS EN752-4, then the higher criteria must be met in order to achieve the credit. None of the credits can be awarded where the assessed development has proceeded against the recommendation of the statutory body on the basis that the flooding implications are too great.

Additional Information Relevant definitions Appropriate Consultant: a consultant with qualifications and experience relevant to the calculation of surface water run-off and design SUDS and flood prevention measures. Where complex flooding calculations and prevention measures are required, this must be a specialist hydrological engineer. Appropriate statutory body: this refers to either the Environment Agency in England and Wales, the Rivers Agency in Northern Ireland, the Scottish Environment Protection Agency in Scotland or the local authorities and internal drainage boards. Catchment: the area contributing surface water flow to a point on a drainage or water course. It can be divided into sub-catchments. Design flood level: the maximum estimated water level during the design storm event. The design flood level for a site can be determined through either known historical data or modelled for the specific site. Design flood event: an historic or notional flood event of a given annual flood probability, against which the suitability of a proposed development is assessed and mitigation measures, if any, are designed. Design storm event: historic or notional weather conditions of a given annual probability, against which the suitability of a proposed development is assessed and mitigation measures, if any, are designed. Flood event: A flooding incident characterised by its peak level or flow, or by its level or flow hydrograph. SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Pol 5 Flood risk 243 Flood probability: The estimated probability of a flood of given magnitude occurring or being exceeded in any specified time period. For example, a 100-year flood has a 1% chance of occurring in any given year. Flood risk: the combination of the flood probability and the magnitude of the potential consequences of the flood event. Flood risk assessment: a study to assess the risk of a site flooding, and to assess the impact that any changes or development on the site will have on flood risk on the site and elsewhere. A Flood Risk Assessment should be prepared according to good practice guidance as outlined in Development and Flood Risk: A practice guide companion to PPS 25, available from www.communities.gov.uk. Flood storage: The temporary storage of excess run-off or river flow in ponds, basins, reservoirs or on the flood plain during a flood event. Flood zone: see table below for definition of flood zones. Greenfield: a site which has either never been built on, or one which has remained undisturbed for five years or more. Greenfield run-off rate: the rate of run-off that would occur from the site in its undeveloped and therefore undisturbed state. Hard surfaces: these include roofs, car parks, access roads, pavements, delivery/service yards and external hard landscaping. Footpaths less than 1.5m wide which have free drainage to soft landscaped areas on both sides may be excluded. ICoP (SUDS): the Interim Code of Practice for Sustainable Drainage Systems (SUDS) aims to facilitate the implementation of sustainable drainage in developments in England and Wales by providing model maintenance agreements and advice on their use. It provides a set of agreements between those public organisations with statutory or regulatory responsibilities relating to SUDS. Available to download from www.ciria.org.uk/suds/icop.htm Infiltration: the passage of water into a permeable surface, such as soil, permeable paving, soakaways and so on. Natural watercourses: any natural channel that conveys surface water. Peak run-off rate (referred to as Qp [m³/sec]): this is the highest rate of flow from a defined catchment area assuming that rainfall is uniformly distributed over the drainage area, considering the entire drainage area as a single unit and estimation of flow at the most downstream point only. Pre-development: the state of the site under assessment immediately prior to purchase of the site by the client/developer (or, where the client has owned/occupied the site for a number of years, its current state). Run-off: this is usually rainwater, but can also be groundwater or overspill from sewers and other sources. Run-off rate: the rate of discharge of water from a surface. Run-off attenuation measures: this covers the range of construction and equipment which can be employed to attenuate run-off from hard surfaces and roofs. Measures include: underground storage, oversized pipes, holding ponds, swales, reed beds, permeable paving, green roofs, local or centralised soakaways etc. Peak flow rate: the peak rate of discharge of water from hard surfaces. For the purpose of calculating the peak flow rate volume, a 60 min duration of the design storm event should be used (unless a different duration is required by a statutory body).

Shoreline Management Plan: SMPs provide a large-scale assessment of the risks associated with coastal processes and present a policy framework to reduce these risks to people and the developed, historic and natural environment in a sustainable manner. SUDS - sustainable drainage systems or sustainable (urban) drainage systems: a sequence of management practices and control structures designed to drain surface water in a more sustainable fashion than some conventional techniques. SUDS devices include: • • • • • • • • Holding ponds Swales Reed beds Permeable paving - in areas where local geological and hydrological conditions allow this to function, e.g. block paved surface on permeable sub-base over gravel bed to store the water and allow it to seep into the soil. For less permeable soils, the gravel layer might be deeper and the water taken to a soakaway although this is not an option in some areas. Local or centralised soakaways either as full systems or as ‘overflow’ or ‘holding’ systems, in areas where local geological and hydrological conditions allow them to function. Run-off from roofs collected as a part of a rainwater harvesting system. Run-off from roofs directed to a local soakaway or other holding facility such as tanks, ponds, swales etc. Green roofs. Surface Water Run-off: water flow over the ground surface to a drainage system. This occurs if the ground is impermeable, is saturated or if the rainfall is particularly intense. Flood zones Flood zones are defined in the relevant planning, policy and technical guidance documents for each country in the UK: PPS25 (England), TAN15 (Wales), SPP7 (Scotland), PPS15 (N. Ireland). Please note, PPS15 does not categorise flood risk zones and there are no similar publicly available flood maps covering Northern Ireland. Assessments in NI will therefore need to rely on site-specific flood risk assessments, or other relevant date/surveys, to determine the extent of flood risk for a specific development, and use the same definitions as those outlined for England (table below). The Northern Ireland Department of Environment or Rivers Agency may offer further advice or recommendations in this respect www.doeni.gov.uk/ and www.riversagencyni.gov.uk/ Whilst the definitions of flood zones and probabilities of flooding are generally the same throughout the UK, there are some differences. The definitions are outlined in the table below. SD5054 issue 4.1 Uncontrolled copy if printed.

Low to medium risk area Watercourse, tidal or coastal flooding in the range 0.1% – 0.5% (1:1000 – 1:200). High annual probability of flooding Zone 3a High Probability 1 in 100 or greater chance of river flooding(>1%) and a 1 in 200 or greater chance of flooding from the sea (>0.5%). * For the purposes of BREEAM assume upper probability of flooding no greater than that specified for England. Zone C1 & C2 * For the purposes of BREEAM assume the same lower and upper probability of flooding as that specified for England. 245 Medium to high risk areas Annual probability of watercourse, tidal or coastal flooding: greater than 0.5% (1:200) Zone 3b The Functional Floodplain Land where water has to flow or be stored in times of flood. Flood defences Flood defences do not completely remove the risk of flooding, but they do reduce it. Building in areas where flood defences are present (and appropriately designed to withstand a certain magnitude of flooding) is therefore preferable to those built in medium/high risk areas without defences. However, for the purpose of this issue, it is still preferable to build in areas of low risk than encourage development of new flood defences in areas with a higher risk of flooding purely for the sake of new development.

Refer to PPG3 for additional guidance. Where the assessment is of an individual building on an existing site, i.e. infill development, the criteria apply to areas within the construction zone that present a risk of pollution, as well as any areas external to the construction zone that are affected by the new works i.e. drainage onto or from the proposed development. Suitable level of treatment In all cases the assessor should determine the operational use of the site in order to determine if the proposed surface water run-off strategy is suitable. Rainwater run-off This issue is not intended to cover the treatment of rainwater run-off except where there is a risk of significant pollution arising. Where it can be demonstrated that there will be no drainage or wash down facilities that may lead water from inside the underground or covered area to natural watercourses, then such areas comply with the assessment criteria by default. Underground/ covered areas Roof plant Roof top plant space must be considered where there is a risk from substances such as petrol or oil. Refrigerants are not assessed under this issue, as the only risk of pollution is to air and not the watercourse. No areas at risk from pollution Where it can be demonstrated that there are no external areas that present a pollution risk, e.g. parking, delivery, manoeuvring or servicing facilities (including individual parking spaces), external waste storage space or other hard standing areas AND there is no plant supported on the roof, then this credit can be awarded by default. Permeable paving system Where it can be demonstrated that a permeable paving system designed to retain silts and degrade oils has been used, then this will meet the assessment criteria of this issue for car parks and access roads.

Additional Information Relevant definitions Appropriate statutory body: This refers to either the Environment Agency in England & Wales, the Environment and Heritage Service (EHS) in Northern Ireland or the Scottish Environment Protection Agency in Scotland. Low risk areas: Low risk areas can be defined as areas where the risk of contamination or spillage of substances such as petrol and oil is reduced. For the purpose of this credit, roofs and small car parks may be considered as low risk areas. Soakaways: A sub-surface structure designed to promote the infiltration of surface water in to the ground. As a general point, soakaways may be shallow and broad – as in a blanket under permeable paving, or deeper structures. Deeper, point source soakaways should be avoided for road and car-park drainage, but shallow structures providing infiltration in an extensive way (infiltration trenches and permeable paving) do not need oil separators. See Pollution Prevention Guideline (PPG) 3 “Use and design of oil separators in surface water drainage systems”, Environment Agency/SEPA/Environment & Heritage Service, 2006 for further guidance. Types of Oil Separator • Class 1 Separators: These are designed to achieve a concentration of less than 5mg/l oil under standard test conditions. They should be used when the separator is required to remove very small oil droplets, such as those arising from car park run-off. • Class 2 Separators: These are designed to achieve a concentration of less than 100mg/l oil under standard test conditions. They are suitable for dealing with discharges where a lower quality requirement applies and/or for trapping large spillages. Both classes can be produced as ‘full retention’ or ‘by pass’ separators: • Full retention separators treat the flow that can be delivered by the drainage system, which is normally equivalent to the flow generated by a rainfall intensity of 50mm/hr. • Bypass separators fully treat all flows generated by rainfall rates of up to 5mm/hr. Flows above this rate are allowed to bypass the separator. These separators are used when it is an acceptable risk not to provide full treatment for high flows. Pollution Prevention Guideline 3 contains more detailed guidance on the selection and sizing of an appropriate type of separator. SD5054 issue 4.1 Uncontrolled copy if printed.

Assessment Criteria The following demonstrates compliance: 1. The external lighting strategy has been designed in compliance with Table 1 (and its accompanying notes) of the ILE Guidance notes for the reduction of obtrusive light, 200578, (see Additional Information below - Buildings located in Scotland must also refer to the Compliance Notes below for additional criteria). 2. All external lighting (except for safety and security lighting) can be automatically switched off between 2300hrs and 0700hrs. This can be achieved by providing a timer for all external lighting set to the appropriate hours. 3. If safety or security lighting is provided and will be used between 2300hrs and 0700hrs, this part of the lighting system complies with the lower levels of lighting recommended during these hours in Table 1 of the ILE’s Guidance notes, for example by using an automatic switch to reduce the lighting levels at 2300 or earlier. 4. Illuminated advertisements, where specified, must be designed in compliance with ILE Technical Report 5 – The Brightness of Illuminated Advertisements79. Compliance Notes New Build There are no additional or different criteria to those outlined above specific to new build projects. Refurbishment For refurbishment projects, in addition to any new external lighting specified, any existing lighting that will remain post development must be assessed against the criteria of this issue. Extensions to existing buildings If the scope of the assessment covers the new extension only, then it is only new lighting specified as part of that extended works that must be assessed against the criteria for this issue. If the new and existing building is being assessed as one, then the rule for refurbishments (above) applies to the existing building. Entire new development Where the assessment is of an entire new development, the criteria apply sitewide. Individual building on existing site Where the assessment is of an individual building on an existing site then only those areas affected by the works i.e. within the construction zone, must be assessed.

This can be demonstrated via completion of the checklists in Annexes B and C of this document by a relevant member of the design team. Flush stud lights used for safety purposes in vehicle manoeuvring areas may be excluded from the assessment. Safety lights Floodlighting, signage lighting Essential lighting between 2300 and 0700 Specific security criteria The guidance notes recommend the setting of a curfew, during which all nonessential external lighting is switched off. This will normally include floodlighting, signage and all lighting that is not required for safety or security. Where essential lighting is provided between 2300 and 0700, i.e. for 24-hour operating buildings, the system is able to automatically switch to the lower levels of lighting recommended in the ILE Guidance notes for lighting during these hours (or provide these lower levels at all times). Any light fittings in the areas outlined above that are specified to comply with specific security criteria/standards, and where those criteria and the BREEAM assessment criteria are not complementary, can be excluded from the assessment of this issue. In these circumstances the assessor must obtain evidence confirming that such criteria are applicable to the assessed development. Schedule of Evidence Required Req.

The ILE Guidance notes for the Reduction of Obtrusive Light, 2005 are available free of charge from the ILE website www.ile.org.uk. Table 1 of ILE guidance Table 1 of the ILE guidance and its accompanying notes outlines four sets of recommendations: 1. Limits to the average upward light ratio of the luminaires, to restrict sky glow. 2. Limiting illuminance at the windows of nearby properties for which light trespass might be an issue. 3. Limiting the intensity of each light source in potentially obtrusive directions beyond the site boundaries. 4. Limiting the average luminance of the building, if it is floodlit. In each case the limiting values depend on the location of the site of the building (for example rural, urban or city centre). A calculation of illuminance (b) or intensity (c) is not required if all luminaires are cut-off types and angled so that light in potentially obtrusive directions is blocked.

For a list and contact details of BREEAM Accredited Professionals visit www.greenbooklive.com Approved Innovation: Any technology, method or process that can be shown to improve the sustainability performance of a building’s design, construction, operation, maintenance or demolition, and which is approved as innovative by BRE Global. See Innovation Application Form (available from the Assessor Extranet) or scoring and weighting section (section 3) of this technical guide. Procedure for reviewing applications for BREEAM Innovations and awarding BREEAM credits for approved Innovations Applications for approval of Innovations can only be made by Licensed BREEAM Assessors with reference to a specific registered assessment. Applications will only be accepted when submitted on the formal Innovation Application Form (downloaded from the Assessor Extranet). A flat rate charge will be levied to cover the costs of administering and reviewing the application. Details of this charge are set out in the BREEAM Certification and Licence Fee Sheet and are non refundable. A separate application will be required for each proposed innovation credit. The process for approving Innovations is as follows: 1. On receipt of an application form, the BREEAM office will carry out an administrative review to ensure completeness. An acknowledgement will be sent by email giving a credit application reference number which should be used in all correspondence. This acknowledgement will be sent within 3 working days. 2. The application will be forwarded for peer review by one or more experts from the BRE Group of companies and where/if appropriate individual(s) from a relevant external organisation. All expert reviewers will be asked to declare any interest that they may have in the project SD5054 issue 4.1 Uncontrolled copy if printed. Valid on day of printing only © BRE Global Ltd 2012 BREEAM Prisons 2008 Inn 1 Innovation 259 concerned and no confidential information concerning the applicant or application will be communicated to an external organisation. 3. The expert will independently review the submission against the criteria outlined in the Eligibility criteria in the Scoring and Weightings section. The review will result in a recommendation for or against approval, together with a justification for that decision. The expert will review the application based on the descriptions and commitments made in the Innovation Application Form and their knowledge/expertise of the subject matter. 4. The BREEAM office will prepare a report setting out a clear recommendation based on the expert review. 5. BREEAM’s Technical Director will review the report and make a final decision on whether to approve or not approve the Innovation. 6. The final decision will typically be communicated to the Assessor by email within 20 working days from receipt of the initial application. 7. Finally, to achieve the credit for the approved Innovation the design team must demonstrate to the BREEAM Assessor that the building meets the criteria defined in the application form. If the design/project team are unable to provide the BREEAM Assessor with auditable evidence of compliance, then the additional credit for the approved Innovation must be withheld. Appeals against any decision can be made in accordance with BRE Global’s published appeals procedures which are available on request. The decision made on any appeal is final. Appeals will be subject to a flat rate charge per application; in the instance of a successful appeal, the appeal fee will be refunded. At final certification of the project, BRE Global will publish basic information on all approved Innovations included within the Post Construction stage assessment. This will be done in a way that is sensitive to applicant’s intellectual property and commercial rights, who will be given a chance to comment on, and if necessary amend, entries before they are made public. BREEAM Assessors and Accredited Professionals will have access to a list of previously approved or not approved Innovations published on the Assessor Extranet. This list will be updated regularly. Innovations are considered to be so until information on the Approved Innovation is published. In the instance of similar Innovation being submitted concurrently by independent projects BREEAM Assessors and clients can expect BRE Global to make a reasonable assessment of whether the later submission can still be held as Innovative as described in credit criterion. BRE Global will not review, or charge a BREEAM Assessor for an identical application that has previously been applied for and not approved. SD5054 issue 4.1 Uncontrolled copy if printed.

All new schemes claiming to meet the criteria listed below will be evaluated by BRE, and will be included in the list of compliant schemes where appropriate. Table 30 Features of a top tier (1) comparable certification scheme: Standard setting When setting standards for a materials certification scheme the following should be addressed in order to be considered comparable to Tier 1/2 of this issue. • The scheme must include a third party chain of custody certification scheme covering all stages of the product throughout the supply chain • The scheme must verify that all local and national legislative criteria are met. • The process for policy and standards development is transparent, clear and accessible. • The scheme is independent and standards are developed in a way which balances the interests of all stakeholders. This should be done through a rigorous consultation process which makes best use of the stakeholder knowledge, methodically and comprehensively considering all feedback and after such consideration, aims to implement all feasible stakeholder suggestions • The scheme is inclusive, striving to involve all interested people and groups in the development of the scheme’s policies and standards. • Monitoring and assessment must be integral to the scheme and conducted appropriate to the scale and intensity of the industry/ materials assessed by the scheme. This requirement is likely to be fulfilled by the incorporation of an EMS such as ISO14001 or BS8555 for SME’s. • The scheme should contain principles by which the scheme should be governed. These should be specific to industry/materials but should also be composed of the fundamental issues related to the environment. These issues should focus on specific practices associated with sourcing virgin and other materials. • The scheme should assess that initiatives are in place to ensure continuous performance and environmental improvement. • The scheme should provide for small to medium sized business as well as larger businesses. SME’s grouping together to achieve group certification should be an option. This could, for example, take place on a regional or other relevant basis. • The scheme should include a mechanism to revise the standard within a defined, suitable time frame to ensure that the current knowledge or upcoming robust scientific or other professional evidence can be incorporated (in good time) into the standard as an update. It should ensure that all updates are well adapted to the local/regional and/or global conditions. • The scheme should also aim to consider social and economic aspects widening the scope to sustainability under the umbrella of a Corporate Social Responsibility (CSR). This is in line with the future aims of BREEAM and could be assessed within this issue in the future. NOTE: The scheme may be generic for the materials industries or specific for individual materials sectors. SD5054 issue 4.1 Uncontrolled copy if printed.

These are outlined below: 1. The top tier category schemes comprehensively address a consultation process with local community. This is done at source via a management company, as the focus is on sustainable project management at source. 2. The top tier category must have no reservations/uncertainty/pending charge or indictment identified by any professional bodies in the relevant materials sectors.

This guidance document is to be used for BREEAM 2008 assessments, where an ecologist has been appointed and produced an ecology report as part of a proposed development. 2. As an ecologist may have been appointed to carry out ecological site surveys and produced an ecology report without being aware that a BREEAM assessment has been, or is to be conducted, the purpose of this document is to help assist assessors relate the contents of such a report to the land use and ecology criteria of BREEAM. 3. The assessor is to request that the appointed ecologist complete all sections of this guidance and return it to the BREEAM assessor along with all relevant documentation required to demonstrate compliance with the BREEAM criteria. 4.

The definition of major and minor refurbishment has been amended to provide additional guidance on the appropriate use of BREEAM for these types of project. Guidance has been added to section 3.3 (minimum standards) concerning the application and exemption of the minimum standards to refurbishment and fit out projects. This is in accordance with the communication in the March 2010 BREEAM Assessors process note. A compliance note has been added on the issue of which CCS monitors report to use for the purpose of determining the number of BREEAM credits, where there have been multiple CCS monitor visits and reports. The term "non discounted" has been removed from requirement 3 of the first credit. Essentially there is no difference between the term real and non discounted cash flow. A definition from ISO15686 for real and discounted cash flow has been added to the additional information section. The reference to the definition of occupied space in the relevant definitions section has been removed as ‘occupied space’ is not referred to in the criteria. The following paragraph has been removed from the Additional Information section: "Wood products that contain phenolformaldehyde (PF) generally emit formaldehyde at considerably lower rates than those containing urea-formaldehyde (UF). Although formaldehyde is present in both types of resins, pressed woods that contain PF would be preferable to those containing UF resin." A compliance note has been added concerning floor finishes and compliance with BS EN 14041 in relation to Formaldehyde emissions and the reference to BS EN 13986 has been updated. Reference added to CIBSE TM39 Building Energy Metering. The header title in the BREEAM Prisons scheme document states that two credits are available for this issue. There is only one credit available for this issue in the Prisons scheme. The header has therefore been updated accordingly. A compliance note has been added outlining exemptions to this issue i.e. simple platform/wheelchair lifts and ramps. A compliance note has been added concerning compliance with the requirement for optimising the counterbalance ratio. Additional text added to the compliance note concerning "Compliant public transport node" to clarify that national public transport services should not be included in the calculation of AI. A compliance note has been added giving guidance for projects where a proprietary (manufactured) cycle system has been specified. This note is in accordance with the guidance published in the June 2009 Assessors Process note Criteria requirement 2b stated "….a flow rate above a pre-set minimum for a pre-set period of time", the word "minimum" has been changed to "maximum" in accordance with the objective of the requirement.

A definition of element number has been added to the Additional Information section. Tier 2 in the responsible sourcing table has been split in to tier 2a and 2b. This is in accordance with the guidance in December 2009 BREEAM Assessor’s process note, to differentiate certification schemes that achieve a Good rating from those that achieve a Pass rating under BES:6001 Responsible Sourcing Standard. The calculation procedure for the Mat 5 calculator tool in the additional guidance section of issue Mat 5 has been updated in accordance with the communication in the December 2009 BREEAM Assessor's process note and the introduction of an online responsible sourcing tool. A definition added for the online Responsible Sourcing Calculator A note has been added alongside the Responsible Sourcing Criteria and Tier Levels table regarding PEFC International's endorsement of the MTCC scheme and therefore the circumstances in which MTCC certified timber can be considered as a tier 1 compliant scheme. This change is in accordance with the guidance communicated to assessors in the July 2009 edition of the Assessors Process note. The note concerning in-situ concrete in the table of responsible sourcing tier levels and criteria has been updated to clarify the requirement for concrete mixed on site. Also, a note has been added at the bottom of the responsible sourcing table containing guidance on the need for a certified EMS for products/manufacturers certified against BES6001:2008. This is in accordance with the communication to BREEAM Assessors in the September 2009 process note. A compliance note has been added concerning the responsible sourcing of insulation materials, specifically making the reader aware that this is covered in BREEAM issue Mat 6 Insulation. In the compliance note: "Not all additional items are applicable" where there are only four items applicable, the requirements to achieve one credit has been amended from "three additional items" to "two additional items" to bring in line with the standard requirement for achieving the first credit available for this issue. A compliance note has been added concerning appropriate action for refrigeration systems that use ammonia as a refrigerant. The compliance note concerning awarding the credit by default where Carbon Dioxide has been used as the refrigeration has been updated to include a requirement that the system must comply with the BS EN 378 and Institute of Refrigeration code of practice for Carbon Dioxide. The factor given for converting figures in mg/MJ to mg/kWh is subject to a formatting error. Previous issue stated that figures in mg/MJ should be divided by 3.6, when in fact they should be multiplied. This has been amended. A formula has been added to the additional information section for determining NOx emissions from heat pumps. SD5054 issue 4.1 Uncontrolled copy if printed.
