Amendments to the 2018 International Energy Conservation Code
The following sections, paragraphs, and sentences of the 2018 International Energy Conservation Code
(IECC) are hereby amended as follows: Standard type is text from the IECC. Underlined type is text
inserted. Lined through type is deleted text from IECC. A double (**) asterisk at the beginning of a section
identifies an amendment carried over from the 2015 edition of the code and a triple (***) asterisk identifies
a new or revised amendment with the 2018 code. Section numbers in parenthesis represent the
corresponding numbers of the energy provisions of the 2018 International Residen tial Code for parallel
amendments.
**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 certifica tion 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
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 R402.4.1.2 (N1102.4.1.2) and R403.3.3 (N1103.3.3) 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 R202; add the following definition:
DYNAMIC GLAZING. Any fenestration product that has the fully reversible ability to change its
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.)
**Section R202 Definitions; 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 2015 IECC. This added definition is
necessary as part of that amendment. The amendment will provide additional options for SHGC
selection.)
***Table 402.1.2 INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENT; the
Fenestration U-factor for Climate Zone 3 is amended as follows:

CLIMATE
ZONE
FENESTRATION
U-FACTOR
3 0.32 0.35
(Reason: Carries forward the value in the 2015 IECC.)
***Table 402.1.4 EQUIVALENT U-FACTORS; the Fenestration U-factor for Climate Zone 3 is
amended as follows:
CLIMATE

FENESTRATION
U-FACTOR
3 0.32 0.35
(Reason: Carries forward the value in the 2015 IECC.)
***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.

a North oriented means within 45 degrees of true north.
(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 and 2015 IECC. This added
definition is necessary as part of that amendment. The amendment will provide additional options for
SHGC selection.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.4 Testing options for R2 multifamily dwelling units. As an option to the air leakage rate set
out in Section R402.4.1.2, multifamily dwelling units will be considered compliant when tested and verified
as having an air leakage rate to the air leakage rate set out in either Section R402.4.1.4.1 or Section
R402.4.1.4.2 when tested and reported in accordance with the testing standards and reporting criteria
listed in Section R402.4.1.2
R402.4.1.4.1 Total air leakage rate for interior multifamily dwelling units. Interior
multifamily dwelling units with a measured, “unguarded” total air leakage result of 5.3 ACH50 or
less shall be considered compliant.
8
R402.4.1.4.2 Total air leakage rate for corner multifamily dwelling units. Corner
multifamily units with a measured, “unguarded” total leakage result of less than 5.0 ACH50 shall
be considered compliant.
(Reason: The Mandatory Section R402.4 Air Leakage of the 2015 IECC requires that the building
thermal envelope be tested and verified in accordance with R402.4.1.2. Measuring air leakage for
multifamily buildings or dwelling units using an air leakage to outside test (i.e. guarded) can be costly and
time prohibitive. This is because in order to isolate leakage only through the building thermal envelope,
all leakage to adjacent units through adiabatic surfaces must be pressure neutralized. The methodology
below therefore allows for the use of total air leakage testing for multifamily dwelling units that includes air
leakage to the exterior and to adjacent units (i.e. unguarded) to show compliance with R402.4.1.2. This
increases the flexibility of the code without affecting stringency. This methodology has been approved for
use by ESL, and the methodology applies only to jurisdictions in the NCTCOG area.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.5 Sampling options for R2 multifamily dwelling units. For buildings having three or more
dwelling units, a minimum of 15% of the dwelling units in each building must be tested as required by
Section R402.4.1.2. Prior to beginning sampling for testing, “Initial Testing” is required for each
multifamily property. “Initial Testing” shall consist of the 3 rd party testing contractor performing the
required tests on at least t hree consecutive dwelling units. Test results from the “Initial Testing” must
satisfy minimum code requirements before sampling is permitted. Dwelling units selected for the “Initial
Testing” must be within the same building. Dwelling units selected for “Initial Testing” shall not be
included in a “sample group” or counted toward the minimum 15% of dwelling units tested. The
building official shall randomly select the three dwelling units for “Initial Testing.” The building official
may delegate the rand om selection to the designated 3 rd party testing contractor.
R402.4.1.5.1 Sample group Identification and Sampling. The builder shall identify a "sample
group" which may be a building, floor, fire area or portion thereof. All of the dwelling units
within the “sample group” must be at the same stage of construction and must be ready for
testing. The building official shall randomly select at least 15% of dwelling units from each
“sample group” for testing. The building official may delegate the random se lection to the
designated 3rd party testing contractor.
If each tested dwelling unit within a “sample group” meets the minimum code requirements,
then all dwelling units in the “sample group” are considered to meet the minimum code
requirements.
Before a building may be deemed compliant with the testing as required, each “sample group”
must be deemed compliant with the minimum code requirements. The sum total of all of the
tested dwelling units across all “sample groups” shall not be less than a minimum of 15% of the
dwelling units in a building.
R402.4.1.5.2 Failure to Meet Code Requirement(s). If any dwelling units within the identified
“sample group” fail to meet a code requirement as determined by testing, the builder will be
directed to correct the cause(s) of failure, and 30% of the remaining dwelling units in the
“sample group” will be randomly selected for testing by the building official, or third -party testing
contractor, regarding the specific cause(s) of failure.
If any failures occur in the additional dwelling units, all remaining dwelling units in the sample
group must be individually tested for code compliance.
A multifamily property with three failures within a 90-day period is no longer eligible to use
the sampling protocol in that commu nity or project until successfully repeating "Initial
Testing." Sampling may be reinstated after at least three consecutive dwelling units are
individually verified to meet all code requirements.
9
A Certificate of Occupancy may not may be issued for any building until testing has been
performed and deemed to satisfy the minimum code requirements on the dwelling unit(s)
identified for testing.
(Reason: For many multifamily (R2 classifications) projects, it is very costly and time consuming to test
each dwelling unit for projects where there may be dozens of dwelling units in each building. Considering
that the same tradesman generally constructs a building, it is reasonable to deem that construction
practices are consistent and that if a reasonable sampling of units tested pass then all units would pass.
These amendments are very similar to other ordinances/policies from Austin and San Antonio.)
**Section C402.2.8/R402.2.14; Add Section C402.2.7 and R402.2.14 to read as follows:
Section C402.2.8/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 equivalen t material approved by the building
official.
(Reason: This will increase the performance of the insulation by ensuring that the insulation stays in
place.)
**R402.4.1.2 Testing; Add a last paragraph to read as follows:
R402.4.1.2 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 duc t 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).
**R403.3.3 Duct Testing (Mandatory). Add a last paragraph to read as follows:
R403.3.3 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 th at the testing requires specialized
credentials and establishes a conflict of interest baseline).
*** Section R403.3 Ducts; add a new section to read as follows:
R403.3.4.1 Sampling options for R2 multifamily dwelling units. For buildings having three or more
dwelling units, a minimum of 15% of the dwelling units in each building must b e tested as required by
Section R403.3.3. Prior to beginning sampling for testing, “Initial Testing” is required for each
multifamily property. “Initial Testing” shall consist of the 3rd party testing contractor performing the
required tests on at least three consecutive dwelling units. Test results from the “Initial Testing” must
10
satisfy minimum code requirements before sampling is permitted. Dwelling units selected f or the “Initial
Testing” must be within the same building. Dwelling units selected for “Initial Testing” shall not be
included in a “sample group” or counted toward the minimum 15% of dwelling units tested. The
building official shall randomly select the three dwelling units for “Initial Testing.” The building official
may delegate the random selection to the designated 3 rd party testing contractor.
R403.3.4.1.1 Sample group Identification and Sampling. The builder shall identify a "sample
group" which may be a building, floor, fire area or portion thereof. All of the dwelling units
within the “sample group” must be at the same stage of construction and must be ready for
testing. The building official shall randomly select at least 15% of dwelling unit s from each
“sample group” for testing. The building official may delegate the random selection to the
designated 3rd party testing contractor.
If each tested dwelling unit within a “sample group” meets the minimum code requirements,
then all dwelling units in the “sample group” are considered to meet the minimum code
requirements.
Before a building may be deemed compliant with the testing as required, each “sample group”
must be deemed compliant with the minimum code requirements. The sum total of all of the
tested dwelling units across all “sample groups” shall not be less than a minimum of 15% of the
dwelling units in a building.
R403.3.4.1.2 Failure to Meet Code Requirement(s). If any dwelling units within the identified
“sample group” fail to meet a code requirement as determined by testing, the builder will be
directed to correct the cause(s) of failure, and 30% of the remaining dwelling units in the
“sample group” will be randomly selected for testing by the building official, or third -party testing
contractor, regarding the specific cause(s) of failure.
If any failures occur in the additional dwelling units, all remaining dwelling units in the sample
group must be individually tested for code compliance.
A multifamily property with three failures within a 90-day period is no longer eligible to use
the sampling protocol in that community or project until successfully repeating "Initial
Testing." Sampling may be reinstated after at least three consecutive dwelling units are
individually verified to meet all code requirements.
A Certificate of Occupancy may not may be issued for any building until testing has been
performed and deemed to satisfy the minimum code requirements on the dwelling unit(s)
identified for testing.
(Reason: For many multifamily (R2 classifications) projects, it is very costly and time consuming to test
each dwelling unit for projects where there may be dozens of dwelling units in each building. Considering
that the same tradesman generally constructs a building, it is reasonable to deem that construction
practices are consistent and that if a reasonable sampling of units tested pass then all units would pass.
These amendments are very similar to other ordinances/policies from Austin and San Antonio.)
***Section C403.7.4 Energy recovery ventilation systems (Mandatory); add exception #12 to read
as follows:
12. Individual ventilation systems that serve an individual dwelling unit or sleeping unit.
(Reason: This will clarify the intent of the section without requiring the u ser or the code official to analyze
the numbers in the table. So a ventilation system that serves only an individual dwelling unit or sleeping
unit does not require an energy recovery system.)
11
***Section C403.11.1 Duct and Plenum Insulation and Sealing (Mandatory); is amended by adding
a second paragraph to read as follows:
C403.11.1 Environmental ducts and plenums installed in vertical chases, both supply and exhaust, where
the ducts or plenums will not be accessible after construction completion, shall be leak tested in
accordance with the SMACNA HVAC Air Leakage Test Manual to the installed ductwork class and
pressure requirements.
Documentation shall be furnished demonstrating that representative sections totaling not less than 25
percent of the duct area have been tested and that all tested sections comply with the requirements of
this section.
(Reason: Ductwork installed in chases is not accessible after construction completion. Leakage in these
ducts will increase the energy use of the buildings and systems for the life of the building and reduce the
system performance. Since the leakage in the chase enclosed ductwork would be difficult if not
impossible to locate and correct, testing at the time of installation would assure that the ducts are pro perly
installed and efficient.)
***Section R404.1; revised in its entirety to read as follows:
Section R404.1 Lighting equipment (Mandatory). Not less than 75 percent of the lamps in
permanently installed lighting fixtures or not less than 90 75 percent of the permanently installed lighting
fixtures shall contain only high-efficacy lamps.
(Reason: This retains the 2015 language will allow for more flexibility.)
***Section R405.2 ; add the exception to read as follows:
Section R405.2 Mandatory requirements. Compliance with the section requires that the mandatory
provisions identified in Section R401.2 be met. Supply and return ducts not completely inside the building
thermal envelope shall be insulated to an R-value of not less than R-6.
Exceptions:
1. For one and two family dwellings the maximum envelope leakage of 4 ACH50 is permitted
provided the envelope leakage in the Standard Reference Design is 3 ACH50 and all other
requirements of Section R405 are met, including all other mandatory measures. The annual
energy cost or source energy usage of the Proposed Design must be equal to or less than
that of the Standard Reference Design.
2. For multifamily or townhomes and buildings classified as Group R2 and Group R4 of three
stories or less the maximum envelope leakage of less than 5 ACH50 is permitted provided
the envelope leakage in the Standard Reference Design is 3 ACH50 and all other
requirements of Section R405 are met, including all other mandatory measures. The annual
energy cost or source energy usage of the Proposed Design must be equal to or less than
that of the Standard Reference Design.
(Reason: This ACH tradeoff is approved by ESL and will require additional energy efficiencies to be
implemented. This tradeoff is incorporated in ESL’s IC3 Code Compliance Calculator as the 2015
NCTCOG path in the code drop down menu. Builders using IC3 will receive a code compliant notification
if their designs meet the requirements of this tradeoff and all other energy code requirements.
Other compliance software products have not incorporated this tradeoff into their compliance reports.
Building Officials receiving Section R405 submittals from software other than IC3 may approve a R405
compliance report that designates the building as not in compliance due to noncompliance with the 3
ACH50 envelope leakage mandatory measure, provided the report also states that the envelope leakage
is no greater than 4 ACH50 for single family homes . REScheck™ does not have the flexibility to
accommodate this tradeoff.)
**Section R405.6.2; Specific approval. Add the following sentence to the end of paragraph:
12
R405.6.2 Acceptable performance software simulation tools may include, but are not limited to,
REM RateTM, 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.)
***Section C405.9. Voltage drop in feeders; deleted in its entirety.
(Reason: There are similar provisions in the NEC where this type of requirement is best managed.)
**TABLE R406.4 MAXIMUM ENERGY RATING INDEX; amend to read as follows:
TABLE R406.41

CLIMATE ZONE ENERGY RATING INDEX
3 65
1 This table is effective until August 31, 2019.
TABLE R406.42

TABLE R406.43
MAXIMUM ENERGY RATING INDEX
CLIMATE ZONE ENERGY RATING INDEX
3 59
3 This table is effective on or after September 1, 2022.
(Reason: The tables reflect the values and time table set forth in HB1736.)
***Section C408.3.1 Functional Testing; amend to read as follows:
C408.3.1 Functional Testing. Prior to passing final inspection, the registered design professional or
approved agency shall provide evidence that the lighting control systems have been tested to ensure that
control hardware and software are calibrated, adjusted, programmed, and in proper working condition in
accordance with the construction documents and manufacturer’s instructions. Functional testing shall be
in accordance with Sections C408.3.1.1 through C408.3.1.3 for the applicable control type.
(Reason: The addition of ‘or approved agency’ will make the lighting systems requirements match the
mechanical system requirements in C 408.2.1. This will facilitat e and add flexibility to the enforcement of
the commissioning requirements.)
END
