Exhibit A
Recommended Amendments to the
2015 International Energy Conservation Code
North Central Texas Council of Governments Region
(Climate Zone 3 of the IECC)
The following sections, paragraphs, and sentences of the 2015 International Energy Conservation Code
(IECC) are hereby amended as follows: Standard type is text from the IECC. Underlined type is text
inserted. A double (**) asterisk at the beginning of a section identifies an amendment carried over from
the 2012 edition of the code and a triple (***) asterisk identifies a new or revised amendment with the
2015 code.
Note: Historically NCTCOG has limited Chapter 1 amendments in order to allow each city to insert their
local policies and procedures. We now have suggested certain items to be brought to the attention of
cities considering adoption of the code that may be of concern to several jurisdictions. It is still intended
to be discretionary to each city to determine which Chapter 1 amendments to include.
The 2015 IECC contains separate provisions for commercial buildings and for residential buildings 3
stories or less. The provisions of the commercial buildings are preceded by "C" for Commercial. The
provisions for residential buildings 3 stories or less are preceded by "R" for residential buildings. Each set
of provisions are separately applied to buildings within their respective scope. Each set of provisions also
contains a Scope and Administration chapter, a Definitions chapter, a General Requirements chapter and
a chapter containing energy efficiency requirements applicable to building within their respective scope.
Recommended amendments that match sections in each of the respective provisions ("C" and "R") are
written to represent both sections rather than duplicating the recommended amendment in this document.
Sections N1101.2 through N1105 of the 2015 International Residential Code (IRC) are noted to be
extracted from the 2015 IECC. The Building and Residential Advisory Board (BRAB) recommends
amending Chapter 11 [RE] ENERGY EFFICIENCY of the 2015 IRC to refer to the residential provisions of
the 2015 IECC.
The Governor signed HB1736 into law on June 16, 2015. HB1736 adopts energy efficiency chapter of
the International Residential Code as it existing on May 1, 2015, as the energy code for single-family
construction (as defined in Section 388.002 of the Health and Safety Code) effective September 1, 2016.
The recommended amendments to the 2015 IECC have been analyzed by the Energy Systems
Laboratory of the Texas A&M University for stringency with the current Texas Building Energy
Performance Standards (TBEPS) which is the 2009 Edition of the IECC and the energy provisions of the
2009 IRC. Some amendments below are noted that effective September 1, 2016, the proposed
amendment would be deemed less stringent than the provisions of the 2015 IECC and therefore would no
longer be considered a recommended amendment.
**Section C102/R102; add Section C102.1.2 and R102.1.2 to read as follows:
C102.1.2 Alternative compliance. A building certified by a national, state, or local accredited energy
efficiency program and determined by the Energy Systems Laboratory to be in compliance with the
energy efficiency requirements of this section may, at the option of the Code Official, be considered in
compliance. The United States Environmental Protection Agency's Energy Star Program certification of
energy code equivalency shall be considered in compliance.
R102.1.2 Alternative compliance. A building certified by a national, state, or local accredited energy
efficiency program and determined by the Energy Systems Laboratory to be in compliance with the
energy efficiency requirements of this section may, at the option of the Code Official, be considered in
Ordinance No. 2017-34
Repealing Ordinance No. 2012-32; Adopting the 2015 Edition of the International Energy Conservation Code
Page 3
compliance. The United States Environmental Protection Agency's Energy Star Program certification of
energy code equivalency shall be considered in compliance. Regardless of the program or the path to
compliance, each 1- and 2 -family dwelling shall be tested for air and duct leakage as prescribed in
Section R402.4 and R403.3.3 respectively.
(Reason: This amendment is added to allow alternative compliance in accordance with Texas HB 1365,
78th Legislature. Codified in Chapter 388 Texas Building Energy Performance Standards: §388.003(i).
The last sentence to Section R102.1.2 was added to insure that every house is tested in accordance with
the mandatory provisions of the code.)
Section C202 and R202; add the following definition:
***PROJECTION FACTOR. The ratio of the horizontal depth of the overhang, eave or permanently
attached shading device, divided by the distance measured vertically from the bottom of the fenestration
glazing to the underside of the overhang, eave or permanently attached shading device.
(Reason: The amendment to Section 402.3.2 Glazed fenestration SHGC was proposed by the TAB
and ESL determined the proposal to be not less restrictive than the 2009, 2012 and 2015 IECC. This
added definition is necessary as part of that amendment. The amendment will provide additional options
for SHGC selection.)
Section R202; add the following definition:
***DYNAMIC GLAZING. Any fenestration product that has the fully reversible ability to change it
performance properties, including U -factor, solar heat gain coefficient (SHGC), or visible transmittance
(VT)
(Reason: This term is referenced in Section R402.3.2. This definition of DYMANIC GLAZING is also
found in the Commercial provisions of the code.)
** Table R402.1.2 INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENT; Amend
by changing the WOOD FRAME WALL R -VALUE for CLIMATE ZONE 3 to read as follows:
13
(Reason: Retain the values in the 2009 code.)
NOTE: Effective September 1, 2016 this proposed amendment is deemed Tess stringent than the
residential provisions of the 2015 IECC and therefore would not be considered a recommended
amendment.
** Table R402.1.4 EQUIVALENT U -FACTORS; Amend by changing the WOOD FRAME WALL U -
FACTOR for CLIMATE ZONE 3 to read as follows:
0.082
(Reason: Retain the values in the 2009 code.)
NOTE: Effective September 1, 2016 this proposed amendment is deemed less stringent than the
residential provisions of the 2015 IECC and therefore would not be considered a recommended
amendment.

Repealing Ordinance No. 2012-32; Adopting the 2015 Edition of the International Energy Conservation Code

***Section R402.3.2 Glazed fenestration SHGC; amend by adding a paragraph and table following
the exception to read as follows:
Where vertical fenestration is shaded by an overhang, eave, or permanently attached shading
device, the SHGC required in Table R402.1.2 shall be reduced by using the multipliers in Table R402.3.2
SHGC Multipliers for Permanent Projections.

definition is necessary as part of that amendment. The amendment will provide additional options for
SHGC selection.)
**Section R402.4.1.2 Testing; modify the first paragraph to read as follows:
R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage
rate of not exceeding 5 air changes per hour in Climate Zone 3. {Remainder of text unchanged)
(Reason: The 2015 IECC requires mandatory door blower testing on each dwelling unit. The visual
inspection is no longer an option to performance testing. This change will give some additional time for
those builders not currently using a performance approach to adapt construction practices.)
NOTE: Effective September 1, 2016 this proposed amendment is deemed less stringent than the
residential provisions of the 2015 IECC and therefore would not be considered a recommended
amendment.
***R402.4.1.2 Testing; Add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform air infiltration testing
certified by national or state organizations as approved by the building official. The certified individuals
must be an independent third -party entity, and may not be employed; or have any financial interest in the
company that constructs the structure.
(Reason: The 2012/15 International Residential Code (IRC) and International Energy Conservation Code
(IECC) includes enhanced emphasis on envelope infiltration and duct leakage. Significant changes in the
residential energy requirements include more frequent requirement of performance testing for leakage.
Residential Duct systems must be tested unless all ducts and equipment are located within the
Ordinance No. 2017-34
Repealing Ordinance No. 2012-32; Adopting the 2015 Edition of the International Energy Conservation Code
Page 5
conditioned space. Envelope testing is required to demonstrate compliance with maximum allowable
leakage rate. This language puts the regulatory authority on notice that the testing requires specialized
credentials and establishes a conflict of interest baseline).
*** R403.3.3 Duct Testing (Mandatory) Add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform duct testing leakage
testing certified by national or state organizations as approved by the building official. The certified
individuals must be an independent third -party entity, and may not be employed; or have any financial
interest in the company that constructs the structure.
(Reason: The 2015 International Residential Code (IRC) and International Energy Conservation Code
(IECC) includes enhanced emphasis on envelope infiltration and duct leakage. Significant changes in the
residential energy requirements include more frequent requirement of performance testing for leakage.
Residential Duct systems must be tested unless all ducts and equipment are located within the
conditioned space. Envelope testing is required to demonstrate compliance with maximum allowable
leakage rate. This language puts the regulatory authority on notice that the testing requires specialized
credentials and establishes a conflict of interest baseline).
**Section C402.2.7/R402.2; Add Section C402.2.9 and R402.2.14 to read as follows:
Section C402.2.7/R402.2.14 Insulation installed in walls. To insure that insulation remains in place,
insulation installed in walls shall be totally enclosed on all sides consisting of framing lumber, gypsum,
sheathing, wood structural panel sheathing, netting or other equivalent material approved by the building
official.
(Reason: This will increase the performance of the insulation by ensuring that the insulation stays in
place.)
***Section R405.6.2; add the following sentence to the end of paragraph:
Acceptable performance software simulation tools may include, but are not limited to, REM
Rate Im, Energy Gauge and IC3. Other performance software programs accredited by RESNET
BESTEST and having the ability to provide a report as outlined in R405.4.2 may also be
deemed acceptable performance simulation programs and may be considered by the building
official.
(Reason: These performance software tools are accredited by RESNET at the time of recommendation.)
***TABLE R406.4 MAXIMUM ENERGY RATING INDEX; amend to read as follows:
TABLE R406.41
