repair, demolition, removal, moving, and change of occupancy of any existing building, structure or utility
heretofore erected within the City.
103.5.1 Alterations Additions, or Repairs. Additions, alterations or repairs may be made to any building
or structure without requiring the existing building or structure to comply with all the requirements of this
Code, provided that the addition, alteration or repair conforms to that required for a new building or
structure, and the existing building or structure complies with the Code under which it was permitted and
constructed, except as otherwise provided for in this Code.
103.5.2 When Additions, Alterations or Repairs are Not Allowed. Additions, alterations or repairs

AIRCRAFT NOISE REDUCTION
143.1. Scope
1. This section shall apply to any new or remodeled multi-unit dwelling or school/educational use (which
shall mean those uses permitted under the Denver Zoning Code under the Education Use Category or
uses permitted under the Former Chapter 59 under school, elementary or secondary; school, vocational,

the area shown in Exhibit A as the DIA Influence Area.
2. The intent of this language is to mitigate interior noise levels associated with current and future noise due
to the proximity to Denver International Airport.
67
ADMINISTRATION OF THE 2016 DENVER BUILDING CODE
3. These design/construction methods apply only to the exterior façade elements of a building, not
to any interior walls.
4. Design requirements and methods:
a. Design method I. Is a prescriptive method which defines minimum construction requirements
in terms of exterior wall and roof construction, exterior wall and attic insulation, and STC and
OITC ratings of windows and doors, and the configuration of vents for gas appliances and other
venting appliances. No design calculations are required in this method. See Section 143.3. This
design method is allowable for multi-unit dwellings.
b. Design method II. Building design by analysis using the OITL Rating Method. See Section
143.4. This design method is allowable for multi-unit dwellings or school/educational uses.
c. HVAC requirements. Regardless of which design method is used, the HVAC
requirements of Section 143.6 must be met.
5. Current adopted IBC, IRC and IECC Codes—Compliance of a structure to the current
adopted IBC, IRC and IECC does not ensure compliance with requirements set forth in this article.
Conversely compliance with the requirements in this article does not ensure compliance with the
exterior wall and attic insulation and window R-values required in the current adopted IBC, IRC and
IECC.
6. The OITL rating method as outlined in ASTM E 1332 uses a reference sound spectrum that accounts for
the spectral content of noise from aircraft. Therefore, method II inherently takes into account the low
frequency spectral content of jet aircraft noise.
143.2 Definitions. The following words, terms and phrases, when used in this section, shall have the
meanings ascribed to them in this section, except where the context clearly indicates a different
meaning:
1. Acoustical professional is a professional engineer, an Institute of Noise Control Engineering (INCE)
Member or Board Certified INCE member.
2. A-weighted decibels, dB(A) means ten times the logarithm (to the base 10) of a power or intensity
ratio with A-weighting which correlates with the human response to the loudness of sounds.
3. Composite transmission loss means the combined TL rating of all the exterior façade elements for a
room or group of rooms, weighted based on the area and STC rating of each individual element.
4. Facade elements means construction elements of the residence that comprise the building envelope from
the outside surface of the element to the interior surface of the element. Typical façade elements are
doors, windows, wall assemblies, roof assemblies, vents, fireplaces, etc.
5. Noise level reduction (NLR) means a reduction in A-weighted sound levels.
6. Sound transmission class (STC), is the most common rating used in North America to for determining
airborne sound transmission loss between 125 and 4,000 Hz. It was created to provide a single number
rating for interior building partitions that are subjected to noises from speech, television, radio, office
equipment and other mid to high frequency noise sources. The STC rating is calculated in accordance
with ASTM E413 (originally published in 1970). The rating is calculated by comparing the measured
sound transmission loss to a reference contour curve. The STC rating must only be assigned to specimens
tested in a laboratory. If specific materials are not laboratory tested, an acoustic professional can submit a
report to be reviewed and approved by the Building Official.
68
ADMINISTRATION OF THE 2016 DENVER BUILDING CODE
7. Outside inside transmission class (OITC) is calculated in accordance with ASTM E1332 (originally
published in 1990). It was created to provide a single number rating for facades (exterior walls) and
façade elements (windows and doors) that are subject to transportation noises (aircraft, trains,
automobiles, and other low to mid frequency noise sources). The OITC is calculated over the frequency
range of 80 to 4,000 Hz. An apparent OITC rating can be assigned to specimens tested in the field and
in the laboratory.
8. Outside to inside transmission loss (OITL), of a building facade, means in a specified frequency band
ten times the common logarithm of the ratio of the airborne sound power incident on the exterior of the
facade to the sound power transmitted by the facade and radiated to the interior. The quantity so
obtained is expressed in decibels (dB).
9. Remodeling or Remodeled means any construction activity in a structure that includes but is not
limited to:
a. Any addition to the principle structure, or;
b. Any alterations to an exterior façade, including window and door replacement projects. Only
the areas being renovated or replaced require compliance with this section.
10. Sound insulation means the capacity of a structure to prevent sound from reaching a receiving
location.
11. Sound level, of airborne sound means a sound pressure level obtained using a signal to which a
standard frequency weighting has been applied such as A-weighting.
12. Transmission loss (TL) of an exterior façade element means, for a specific frequency band,
the difference between the average sound pressure levels from the source side of the façade
element to the receiving side of the façade element (expressed in decibels) plus ten times the
logarithm to the base 10 of the ratio of the area of the façade element to the total acoustical
(sabine) absorption in the receiving room.
143.3 Design method I. This method requires the registered design professional to follow the
construction requirements for all exterior façade elements as listed in the tables below (Table 143.3).

roofs by pipes, ducts or conduits shall be sealed airtight as required for joints. Door and window
openings in exterior walls shall be flashed all around with an approved vapor barrier and sealed to
prevent air infiltration. All voids at doors and windows caused by shims shall be filled solid with
insulation and sealant. Sill sealant shall be used to prevent air infiltration at all base plates of exterior
walls. Attic and crawl space vents shall not exceed minimums specified by ordinance. Crawl space vents
shall be baffled as shown in figure 143.6.3.2. See section 143.6 for building mechanical systems.
143.4 Design method II. Generally, this requirement is for schools/educational uses, but may also be
utilized for multi-unit dwelling construction. Design method II requires an acoustical professional to follow
the design specifications and construction techniques described in this Section 143.4. An acceptable OITL
rating derived as prescribed in this section will be required prior to approval of building plans. The
acoustical professional is responsible for providing OITL ratings for all façade elements, that were
determined in accordance with either ASIM E 90 (current revision at time of plans submittal N) or ASIM E
966 (current revision at time of plans submittal).
Noise level reduction requirements. All structures shall be designed and constructed so that the exterior
shell of the structure (windows closed) provides an OITL rating of 25 decibels or higher.
2. Design calculations. The OITL rating shall be calculated for each room having an exterior façade
element (basements are explicitly excluded from rooms requiring calculation), using the
composite TL calculation procedure outlined below. The room having the lowest numerical OITL
rating will determine if the building meets the minimum requirements. The construction required
for this room shall then be applied to the entire building structure; that is the window and door TL
ratings shall be applied to all windows in the building, the wall construction shall be applied to all
1.
70
ADMINISTRATION OF THE 2016 DENVER BUILDING CODE
exterior walls in the building, and the roof/ceiling construction shall be applied to all ceiling areas
with exterior areas.
3. In some instances rooms may not have distinct separation lines; i.e., a kitchen adjacent to a family room.
For these cases, when the opening between the rooms is at least 50 percent of the area of the separation
between the rooms (opening plus wall area) then the rooms may be combined into one room.
4. The calculations to determine the OITL rating must be performed by an acoustical professional.
5. Composite transmission loss values used in the OITL rating calculation are determined as
follows. The transmission coefficient (T) of a façade element is the ratio of the sound power
transmitted through the façade element per unit area to the sound power incident on the façade
element per unit area. Transmission loss (TL) is the expression of the transmission coefficient
on a decibel scale. The two quantities are related by
TL = 10 Log10 (1 / τ)
T = 10-TL/10
A transmission coefficient of zero, T = 0, means that none of the incident sound energy passed through
the partition; i.e. the transmission loss is infinity great. A transmission coefficient of one, T = 1, means
that all of the incident sound energy passed through the partition; i.e. the transmission loss is zero. A
TL of zero applied to an open window or door.
The sound energy passing through each component (façade element) of a multi-element partition
depends on the area and transmission loss of each element. The equation governing this process is
Atotal Ttotal = A1T1 + A2T2 + A3T3 + A4T4 + ····
Where, A1 and T1 represent the area and transmission coefficient of the first element (for example
a wall), A2 and T2 represent the area and transmission coefficient of the second element (for
example a window), A3 and T3 represent the area and transmission coefficient of the third element
(for example a door), A4 and T4 represent the area and transmission coefficient of the fourth
element (for example a ceiling/roof assembly) and so on. The quantities ATOTAL and TTOTAL
are for the composite multi-element partition. The transmission coefficient for the composite multielement partition is then represented as Ttotal = A1T1 + A2T2 + A3T3 + ···/ Atotal
The TL for the combined multi-element partition calculated TLtotal = 10 Log10 (1 / Ttotal)
In order to calculate the OITL rating the TLtotal must be determined for each 1/3-octaveband from
80 to 4000 HZ as described in ASTM E 1332.
6.
Construction. All exterior walls, roofs and exposed floors shall be of airtight construction. All nonlap joints shall be grouted or caulked airtight with a non-hardening, non-shrinking sealant installed
in accordance with manufacturer's specifications. Any penetrations of exterior walls or roofs by
pipes, ducts or conduits shall be sealed airtight as required for non-lap joints. Door and window
openings in exterior walls shall be flashed all around with an approved vapor barrier and sealed to
prevent air infiltration. All voids at doors and windows caused by shims shall be filled solid with
insulation and sealant. Sill sealant shall be used to prevent air infiltration at all base plates of
exterior walls. Attic and crawl space vents shall meet specifications given in sections 143.6.2 and
143.6.3.2.

Appendix Q Access control is added:
APPENDIX Q
ACCESS CONTROL
SECTION Q 101
INTRODUCTION
Q101.1 Background. Since 1990 various written policies have been implemented and applied to establish
requirements and guidelines for the assessment and permitting of access control systems. Initially, policies were
written to address the needs that had developed for securing the elevator lobby and stair enclosures in high rise
buildings. As the use of these systems increased, and as they became more complex, it was necessary to
develop a more comprehensive policy to address these systems that were being used in ever increasing
applications. The development of an expanded policy was also driven by the failure of the model building code
to respond to the increasing security needs in buildings. The model building code did not provide a reasonable
balance between life safety concerns and security needs. Further, these systems were found to have a detrimental
effect on exiting, fire department access and accessibility as well as reducing the effectiveness of other lifesafety features in buildings. In order to address this need for a more comprehensive policy, an Access Control
Committee was established to develop the required document. The committee was composed of both private
and public sector members. On April 18, 1995 the Building Inspection Division began to apply the initial policy
developed by this committee. The policy was published as Policy Number 32-B068. Since being
implemented, the original policy was continuously applied and used as the basis for the review and acceptance
of access control systems. In the year 2000, the Access Control Committee was re-established and began to meet
to develop an updated and expanded version of the 1995 policy. This committee developed an updated policy
but that new version was not implemented pending the adoption of the IBC (International Building Code) as
the Building Code for the City & County of Denver.
The DBC includes a number of provisions that relate to access control systems that are similar to some of the
systems and requirements of the new version of the access control policy. However, these provisions are not as
comprehensive as those contained in this policy. In order to codify the policy and to provide a more consolidated
and organized approach to access control it was decided to develop a separate appendix in the building code for
access control systems. The newest version of the access control policy was used as the basis for this appendix.
The provisions of the International Building Code that address issues related to access control systems are deleted
in the Denver Amendments to the IBC and reference is made to this appendix for the appropriate corresponding
requirements.
Q 101.2 Purpose and intent. The purpose of this appendix is to combine all of the various DBC
requirements and previous policy requirements for access control systems into one document. The appendix
is intended to provide consistency in the design, review, installation and inspection of access control systems
and components by providing standards and guidelines for these systems. It is anticipated that redundant design
efforts and administrative modification requests can be avoided by providing safe alternative solutions to some
commonly reoccurring security applications where the use of access control systems would create conflicts
with other requirements of the DBC. Although the appendix contains specific solutions for a number of
common applications it is not intended to limit the use of this policy to only those situations. This appendix
can be used to help devise appropriate solutions to other unique situations that require the use of access control
systems that may also be incompatible with requirements of the DBC. The provisions of the DBC in the
Administration Section relating to modifications under special circumstances can be used when other
solutions provide an equivalent alternative to the provisions of the DBC. The standards and guidelines of this
appendix are designed to assist in the development of specialized access control systems that are necessary to
149
2016 DENVER AMENDMENTS TO THE 2015 INTERNATIONAL BUILDING CODE
respond to unique security needs.
Q 101.3 Prevailing policy. All access control policies and appendices previously applied by Community
Planning and Development are null and void and superseded by this appendix. These policies include but are not
limited to the following policies:
Policy P-25
Securing of Stair Doors into Exit Enclosures – Dated 09/04/1999 Policy P-26
Policy P-47
Interim Policy – Electric Door Hardware Applications for Exit Doors - Dated 09/21/1992
Policy 32-B068
Access Control – Dated 04/18/1995
Appendix L
Access Control – 2011 Amendments to the 2009 IBC - Dated September 2012
Securing of Elevator Lobbies - Dated 02/05/1993
The provisions of this policy are not intended to be applied to existing access control systems that were
permitted and legally installed in accordance with the provisions of the DBC and any Access Control Policy in
effect at the time the permit was issued.
Q 101.4 Modified IBC provisions. The following IBC sections have been modified and are superseded by the
provisions of this appendix:
Section 403.5.3 Stairway door operation.
Section 1010.1.9.7 Delayed egress locks.
Section 1010.1.9.8 Sensor release of electrically locked egress doors.
Section 1010.1.9.9 Electromagnetically locked egress doors.
