INTRODUCTION
General
The Design Guidelines and Technical Criteria included in this manual identify the standards and
preferences of Northwestern University (NU) Facilities Management Department. The Design
Guidelines are organized by subject matter while the Technical Criteria generally follow the
numbering system suggested by the Construction Specification Institute (CSI).
It is intended that these General Guidelines and Technical Criteria serve as a reference for
consultants providing architectural and engineering services for NU design and construction
projects. The Guidelines do not include “standard” or “master” specifications for any
construction material or system.
The translation of these General Guidelines and Technical Criteria into contract documents is
left to the individual consultant. In no instance shall a direct referral to these Design Guidelines
and Technical Criteria be included in contract documents prepared by design consultants, nor
shall any portion of the Technical Criteria be reproduced in project specifications without being
specifically tailored to the individual project.
Since requirements of applicable ordinances, codes, statutes, and regulations are subject to
change, it is the responsibility of the design professional to determine independently that the
project fully complies with all applicable ordinances, codes, statutes, and regulations at the time
of design. If, in the opinion of a design professional working on a specific matter, a requirement
of these guidelines is inconsistent with a requirement of an applicable ordinance, code, statute,
or regulation that compliance with this manual would violate the applicable provision, the design
professional should comply with the applicable ordinance, code, statute, or regulation and
should also advise the NU Project Representative in writing of the apparent inconsistency and
the reasons that the guideline may not be followed.
Modification and Waiver
Users of this guideline, including Facilities Management staff who have suggestions for
modifying or expanding the subject matter covered in these guidelines are encouraged to
submit their suggestions in writing to the Facilities Management representative coordinating
these standards. A form for providing such input is provided in the Appendix to the manual,
although any form of written communication or email is welcome.
Application for waivers to any section of these guidelines shall be made, in writing, by the
Architect/Engineer of Record to the Director of Design and Construction, copying the NU Project
Manager.
The origination date of these standards is January 1, 2014. This guideline is to be reviewed
annually for modification or expansion as determined during the course of the year by Facilities
Management. The period of review of this guideline will be the last quarter of the calendar year.
All modification requests received by October 1 will be reviewed by the Guidelines Review
Committee within 30 to 90 days, with recommendations to be incorporated into this guideline by
the annual date following the origination date.

Sustainability
1. Introduction:
a. This portion of the Design Guidelines and Technical Standards includes the
sustainability guidelines to be followed by the Project Managers, Consultants,
Architects, and/or Engineers in the course of a project at Northwestern
University.
b. Northwestern University recognizes that the environmental impact of our facilities
and infrastructure is significant and that it has implications for the local
community and the world beyond our borders. We are committed to reducing
this impact by reducing materials and waste during construction, designing
buildings that conserve energy and water use, planning and designing
infrastructure that encourages walking and alternative forms of commuting like
cycling and public transit, and creating built environments that provide
opportunities to enhance the performance of the occupants.
c. These guidelines are designed to support Northwestern University’s commitment
to sustainability as stated in the Strategic Plan and to fulfill the President’s
commitment to position Northwestern University as a national leader in
sustainability. These guidelines will help Northwestern University to place clear
parameters and identify measureable results around what it means to be truly
sustainable. The goal is to incorporate sustainable principles, materials, and
actions into building design, construction, and maintenance.
DESIGN GUIDELINES
Page - 13
NORTHWESTERN UNIVERSITY
Design Guidelines
Issuance Date: 01.01.2014
d. These guidelines should be considered at every decision point and economic
and environmental assessments done when necessary to make the right
decisions for the stewardship of Northwestern University campuses.
e. For questions, please contact the Office of Sustainability at
sustainability@northwestern.edu.
2. Sustainability and Integrated Design:
a. The optimal way to ensure that sustainability occurs is by focusing on the
environmental, economic, and social impacts of planning, design, construction,
operations and maintenance to improve resource conservation and create
healthy work and living spaces in a way that is meaningful for the people who
study, teach, work, or live in our buildings.
b. Application of whole-systems design approach is crucial for sustainability. The
sustainability categories and strategies are interdependent; none stand in
isolation. Decisions made in one area may affect the performance in another. A
single design improvement might simultaneously improve several building
systems’ performance.
c. It is essential that all members of the project team work together and consider all
sustainability categories in order to be aware of the influence of their decisions
on the overall sustainability performance of the building in each category. In
addition, not all strategies suggested here are relevant for every project and
certainly not all strategies will be implemented in every project.
d. These decisions are not made in isolation but rather they should recognize the
interactions and tradeoffs of a particular project. Northwestern University’s
sustainability guidelines outline an integrated design approach. The process
steps are identified to establish performance goals and to ensure that decisions
are made in a collaborative and informed manner. The maximum benefits to the
programmatic mission can be achieved when sustainability is incorporated at
every point along the project delivery process.
3. Planning and Project Initiation:
a. Translate academic or departmental initiatives into potential facility needs to
determine if a capital construction project is necessary. As part of that effort,
sustainable features should be discussed in a preliminary sustainability working
session and document by the Northwestern University Project Manager and
stakeholders so that they can be incorporated as the project is developed.
b. Incorporate the sustainability initiatives discussed into the Request for Proposal
(RFP) and Owner’s Project Requirements (OPR) outlined in the Design
Guidelines and Technical Standards. Understand any costs or savings that may
be incurred in order to create an more sustainable building.
4. Programming:
DESIGN GUIDELINES
Page - 14
NORTHWESTERN UNIVERSITY
Design Guidelines
Issuance Date: 01.01.2014
a. During the programming phase, the programming requirements should be further
developed to incorporate sustainability goals as they pertain to the user needs
and design parameters.
b. As the project team develops or verifies the project program, summary schedule,
and preliminary budget, the FM Project Manager should arrange a Sustainability
Working Session (SWS) to review the options and the underlying principles of
sustainability as they relate to the building design, construction, and operation.
c. Programming Consultant is to begin development of the Basis of Design (BOD)
and LEED Checklist in response to the Owner’s Project Requirements (OPR)
and results of the sustainability working session.
5. Schematic Design:
a. The largest resources impacts of the project should be identified, prioritized, and
discussed at design meetings and should include energy, water, materials, and
people. The consultant should be prepared to discuss major mechanical
systems and alternatives like geothermal.
b. Modeling tools such as DOE-2, eQUEST, or ENERGY-10 should be used to
evaluate energy efficient design alternatives and refine the project’s sustainability
goals for energy usage. The results are to be incorporated into the BOD
document and LEED Checklist.
6. Design Development:
a. During the Design Development (DD) phase, the approved schematic design
begins to include a level of detail necessary to work out a clear, coordinated
description of all aspects of the project. Because the DD Phase is one of the last
opportunities for the User Group to become fully involved in the design, it is
crucial that sustainability principles from each of the LEED categories be fully
discussed and implications be understood and integrated as appropriate.
b. Design and construction costs associated with the sustainable attributes of the
project should be clarified. Sustainable component cost metrics (capital and life
cycle) should be developed and cost and/or savings decisions evaluated against
performance and life cycle cost considerations. The results are to be refined
within the BOD document and LEED Checklist.
c. The project team should ensure that the project schedule allows adequate time
for implementing the activities that may lead to a more sustainable project, such
as commissioning, demolition waste diversion, and training.
7. Construction Documents:
a. During the Construction Documents (CD) phase, a comprehensive, fully
coordinated set of construction documents and technical specifications are
issued to obtain the necessary permits and construct the project. A review of
sustainability elements should be included in the preliminary CD review (such as
DESIGN GUIDELINES
Page - 15
NORTHWESTERN UNIVERSITY
Design Guidelines
Issuance Date: 01.01.2014
50% CD review) along with any update of the BOD document and LEED
Checklist. This review should specifically address materials selection.
8. Construction:
a. At the start of the construction phase, a representative from the Construction
Manager (CM) and/or General Contractor (GC), each subcontractor, and
Sustainability Team (FM, FMO, FM OoS), and the Architect/Engineer should
attend the pre-construction meeting. The sustainability goals and design
features of the project should be discussed at this meeting and a review of the
project LEED requirements should occur if applicable.
b. Contractor ideas and opinions should be encouraged during these discussions to
allow for innovations and efficiencies during construction.
Sustainability Guidelines
1. These guidelines are for use by NU Project Managers and consultants on projects of all
scales. Although Northwestern sets LEED Gold as a target for larger projects, each
project should follow these guidelines when applicable.
2. These guidelines are organized into the following categories:
a. Sustainable Sites.
b. Energy.
c. Water.
d. Materials and Resources.
e. Indoor Environmental Quality.
f.
Human Centric.
3. In view of the environmental concerns associated with buildings, sustainable design
embodies certain goals within each category. The discussion of each sustainable
category begins with a set of goals, followed by a list of suggested strategies to be used
in achieving those goals.
4. The sustainability strategies included here are not comprehensive; these guidelines are
intended to provide ideas and not exclude any from consideration. The project team is
encouraged to develop additional strategies and refer to current documents published by
the United States Green Building Council (USGBC) at www.usgbc.org.

iii. Sheen:
1. Level A: Hard-shell, satin finish (400 grit).
2. Level B: Hard-shell, medium sheen finish (800 grit).
3. Level C: Light reflective, mirror finish (1800 grit).
b. The depth of the grind to achieve the desired results is dependent on the
techniques used for finishing, the concrete mix, and the amount of time between
concrete pouring and grinding. To avoid disputes later, however, it is necessary
to specify a minimum required depth of the grind of at least 1/4-inch. That gives
the contractor a starting point to achieve the desired finish results.
c. Utilize a mock-up to determine the final technique.
d. Do not grind and polish lightweight concrete. Shale aggregates will be pulled
from the surface resulting in pits.
19. Field Quality Control – Testing Agency: Typically, Northwestern will engage a qualified
independent testing and inspecting agency to sample materials, perform tests, and

SECTION 26 0000 – ELECTRICAL DESIGN CRITERIA
General Design Criteria
1. General: The Electrical systems within Northwestern’s facilities need to be designed
and maintained to meet the goals of safe, reliable and efficient operation.
2. Safety: Electrical safety is paramount in any facility and that begins with a design that is
safe to operate and maintain. Electrical equipment should be specified and located with
emphasis placed on reduced maintenance exposure, manageable short circuit and
ground fault current, and arc-flash safety.
3. Reliability: Reliability in the electrical system is also critical to meeting the goals of the
University to provide world class technical and health research capabilities. Electrical
systems that are reliable also require less maintenance, have lower operating costs, and
produce less waste.
4. Redundancy: The design must identify and address points of failure for systems serving
critical spaces, which are to be identified with the owner. Redundancy and/or back-up
systems should be identified.
5. Sustainability: Electrical system design should address sustainable design concepts,
energy use reduction, and occupant comfort to meet the goals of NU and the community
it serves.
Sustainability Overview
1. Sustainability is not just about energy efficiency and energy savings. From the
Advanced Lighting Guidelines: “Lighting is primarily provided for people, not for the
buildings or roadways or objects illuminated. Peoples’ needs should determine what
kind of lighting is provided. Meeting those needs is important because a good visual
environment is critical to health, productivity, comfort, aesthetics, safety, communication
and mood. Lighting designers have an opportunity and responsibility to support and
improve the quality of life for everyone. Recently, lighting has become a subject of much
greater interest than for many years. This is for three reasons:
a. The ageing of the population in many developed countries. As the human visual
system ages, its capabilities deteriorate. Lighting can be used to help older
people to see well and hence to live active lives for longer.
b. The need to reduce carbon emissions to minimize climate change. Lighting is a
major user of electricity and the generation of electricity is a major source of
carbon emissions. This means that lighting is under pressure to do more with
less.
c. The recognition that exposure to light can have significant non-visual effects on
human health. The potential for exposure to light to cause tissue damage has
been known for many years, but now its influence on the human circadian

system, which operates at a very basic level of human physiology, is also
appreciated.
d. Taken together, these developments mean that the number of factors that should
be considered when determining if a lighting installation is fit for purpose has
increased. However, one factor that will almost always need to be considered is
how well the lighting enables people to see.”
2. Lighting energy efficiency shall be a significant consideration for all lighting designs. The
following shall be taken into consideration:
a. Efficiency based on ASHRAE 90.1 guidelines – strive to improve efficiency
relative to the guidelines while maintaining lighting quality
b. IESNA guidelines based on the latest IESNA Lighting Handbook
3. Site lighting shall be designed to reduce night sky light pollution.
4. Motor efficiency – motors shall be premium efficiency.

of Group 9, Chapter 15-16 of the City of Chicago Building Code. In
addition, careful research in other chapters pertaining to occupancy is
required to identify special fire alarm needs.
1. For example, dormitory smoke detectors are covered in Group 3,
Chapter 13-64.
ii. On a general basis, two distinct types of fire alarm system requirements
exist: Class I and Class II and equipment must be City of Chicago
approved for use in the alarm system class being installed. Review and
approval of fire alarm plans usually includes both the Fire Prevention
Bureau and Electrical Inspection Bureau.
iii. In the Building Code, references to NFPA fire alarm and detection
standards covers a range of years from 1984 to 1993 requiring careful
coordination in the specifications. (Note: the example specification needs
considerable revision for use on a City of Chicago project.)

Design and Shop Drawing Review Process
1. All projects will be reviewed with the Building Department and the Fire Prevention
Bureau at the schematic design stage.
2. Large projects will be reviewed by the University insurance carrier at the
Schematic, Design Development and Construction Document levels.
3. Temporary FA system layout for renovations during the construction period will
be designed or sketched by the existing FA manufacturer or general contractor. It
is best if this sketch can be included in the renovation design drawings for permit.
If it is not in the bid package, the sketch will be reviewed and approved by both
the NU Electrical Shop and Risk Management. Upon approval, the sketch will be
forwarded to EFD for approval. The temporary system will be tested by the
Electrical Shop and witnessed by Risk Management. Once the temporary system
layout which may include fire extinguishers, mast mounted pull stations,
audio/visual devices and heat detectors (may be similar to the air wired “safety
station” below) is tested the existing FA and FS systems can be taken out of
service. The temporary system must be active until the final FA and FS systems
have been tested and approved. The Electrical Shop will confirm the removal of
the temporary system with a copy to EFD.
4. FA and FS shop drawings will be reviewed by NU Electrical Shop and Risk
management prior to submission to EFD.
5. Submit FA and FS drawings to EFD. Allow 2 weeks for review.
6. Submit FA and FS drawings to the University insurance carrier for information.

Testing Requirements
(Review sections 01-1000 and 01-5000 of the specification)
Fire Alarm installation testing is comprised of three steps. The installing contractor
shall test all equipment and the entire operation of the system. The contractor
then shall certify to the Office of Risk Management and the Facilities
Management Chief Electrician that the system performs as designed and that it is
in full compliance with the permitted work and relevant codes. The Contractor
shall then make an appointment with the Office of Risk Management to test the
entire system with University electricians and Office of Risk Management
personnel. After completion, Risk Management will then advise the Fire Marshal
that the system is approved for Fire Department testing. The contractor shall then
make an appointment with the Fire Prevention Bureau (through the Evanston
“311 request system” or by calling 847-448-4311 outside of Evanston) for
acceptance testing. When the appointment is made the contractor shall notify
the electric shop and Risk Management of the date and time. The contractor
shall provide a minimum of 2 alarm personnel with radio communications and all
necessary equipment to provide complete testing of each alarm system device at
each test. In addition, the contractor shall provide 3 copies of a list of initiating
devices, with device nomenclature for each test.
Special noise limiting testing precautions must be taken in and around residential
spaces, CCM areas, classroom schedules and clinic schedules.

Point Naming Conventions
Point names shall be the combination of several identifying elements that are represented by a
list of standard abbreviations. Within a point name, the following attributes shall be identified:




Chicago campus,Evanton campus, or off-campus building (denoted by “C”, “E”, “O”) ,
“F” for Fraternity, “S” for Sorority, “H” for Housing
Building (four letter abbreviation)
Equipment tag (if applicable)
Point identifier (setpoint, command, alarm, etc)
Attributes shall be separated by “_” and will go from the building name (four letter
abbreviation) down to point type (ending in _STP, _CMD, etc where applicable). Equipment tags
shall not contain “-“or “/”, and shall be double-digits (i.e. AHU-1 is AHU01 in point name).
The naming convention shall be slightly modified depending on if the point is for a piece of
equipment, virtual point, meter, etc
Examples:
CAMPUS_BUILDING_EQUIPMENTTAG_POINTIDENTIFIER_POINTTYPE
E_COOK_AHU01_DA_TMP_STPT
E_COOK_AHU01_VAV020100:XXX
VAV Box point names shall include AHU tag serving the VAV box (or EF tag for exhaust VAV
boxes)
FOR VAV’S THE FIRST TWO DIGITS AFTER “VAV” WILL REPRESENT THE FLR NUMBER,
FOLLOWED BY A FOUR DIGIT ROOM NUMBER. WHERE MORE THAN ONE VAV BOX SERVE A
SINGLE ROOM THE VAV TAG SHALL END IN “A”, “B”, “C”, ETC FOR EACH BOX. WHERE A VAV
BOX SERVES MULTIPLE ROOMS, THE ROOM NUMBER SHALL BE THE LOCATION OF THE
THERMOSTAT.
Will all equipment tags other than VAVs be two digit number (i.e. AHU01, CHLR02, etc)?

Standard Units, Significant Digits, and Change of Value
The below units, significant digits, and change of value standards shall be used for displaying
values in graphics. For example, a static pressure reading displayed on the graphic shall change
whenever the sensor reading changes by a value of 0.1, but it shall display two decimal
significant digits (i.e. 0.01 significant digits). If a sensor is reading 1.642” w.c., the display shall
show 1.64” w.c., and the value on the screen shall not change until the reading changes by
0.1”w.c. (i.e. when the sensor reading changes to a value that can be rounded to 1.54” w.c. or
1.74” w.c.).

Northwestern University
Scope of BAS Contractor
The purpose of this document is to describe the Enterprise Level Server at Northwestern
University, and the separation of roles between the System Integrator and the Building
Automation System Contractor.
The Enterprise Server consists of the Honeywell Tridium WebsAX running on three Marathon
redundant servers. Two servers are located on the Evanston Campus, and one server is located
on the Chicago Campus. Both the JCI and Siemens head end servers currently reside on this
Marathon redundant server. The long term plan is these two software packages are used for
high level programming only, and will not be used for day to day operations of the JCI or
Siemens BAS.
All new DDC system controllers, terminal device controllers, VFDs, and any other intelligent
control device shall be BTL Certified and shall communicate using BACNET MS/TP. All network
controllers shall communicate to lower level controllers using BACNET MS/TP. Network
controllers shall communicate to each other, and BAS Servers, using BACNET/IP.
The control contractor shall provide a complete DDC system, which interfaces with both the
control vendors "head end" server, and the Northwestern University Tridium Enterprise Server.
The Owners' normal day to day interface will be with the Tridium Enterprise Server. The
configuration of graphics for the Tridium Enterprise Server will be done by the Owner's System
Integrator. The BAS contractor is responsible for coordinating with the System Integrator to
verify all points are properly transmitted to the Enterprise Server including alarm values and
links to trend files. Provide sufficient manpower to work with the System Integrator to do a
point to point test of alarms, trending, setpoint overrides, etc.
Figure 1 shows a simple schematic of the Enterprise Network.
