Chapter 9 of the Local Government Code; and
WHEREAS, beginning in the spring of 2012, NCTCOG's Regional Codes
Coordinating Committee (RCCC) and its four advisory boards conducted open review
meetings over a 1 -year period to review the 2012 editions of the International Codes and to
develop regional amendments. Their review and recommendations were completed and
endorsed by NCTCOG's Executive Board in March 2013. Now NCTCOG encourages
jurisdictions in North Central Texas to adopt the 2012 International Energy Conservation
Code along with its respective regional amendments with an effective date of April 1, 2014:
•
NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF
SOUTHLAKE, TEXAS:
SECTION 1
That the International Energy Conservation Code, 2012 Edition, published by the
International Code Council, including the standards referenced therein, is hereby adopted
as the Energy Conservation Code of the City of Southlake regulating the design of building
envelopes for adequate thermal resistance and low air leakage and the design and
selection of mechanical, electrical, service water - heating and illumination systems and
equipment in the City of Southlake, except for facilities otherwise regulated under the
International Residential Code for One- and Two- Family Dwellings as adopted. A true and
correct copy of this document is attached as Exhibit "A."
SECTION 2
That the 2012 International Energy Conservation Code, as adopted herein, is
hereby amended as_provided in Exhibit "B" incorporated herein and attached hereto for all
purposes of this ordinance. The City of Southlake, Texas may from time to time determine
that additional local modifications to the Energy Conservation Code are necessary and
appropriate to meet the unique needs of the City of Southlake, Texas. To effectuate these
local modifications, the City Council shall enact individual ordinances amending this
Ordinance, fully setting forth the change to be made in the Energy Conservation Code.
These amendments shall be consolidated as Exhibit "B" to this Ordinance.
SECTION 3
The material contained in Exhibits "A" and "B" to this ordinance shall not be
included in the formal municipal codification of ordinances, but shall be maintained as a

Southlake, Texas, except where the provisions of this ordinance are in direct conflict with
the provisions of such ordinances, in which event the conflicting provisions of such
ordinances are hereby repealed.
SECTION 5
It is hereby declared to be the intention of the City council that the phrases, clauses,
sentences, paragraphs, and sections of this ordinance are severable, and if any phrase,
clause sentence, paragraph or section of this ordinance shall be declared unconstitutional
by the valid judgment or decree of any court of competent jurisdiction, such
unconstitutionality shall not affect any of the remaining phrases, clauses, sentences,

EXHIBIT "B"
Amendments to the 2012 International Energy Conservation Code
The following sections, paragraphs, and sentences of the 2012 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 2009 edition of the code and a triple ( * * *) asterisk identifies a new or revised
amendment with the 2009 code.
The 2012 IECC contains separate provisions for commercial buildings (preceded by "C" for Commercial) and for
residential buildings (preceded by "R" for residential buildings) 3 stories or less. 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 2012 International Residential Code (IRC) are noted to be extracted from
the 2012 IECC. The Building and Residential Advisory Board (BRAB) recommends amending Chapter 11 [RE]
ENERGY EFFICIENCY of the 2012 IRC to refer to the residential provisions of the 2012 IECC.
As of the date of the recommendations the State Energy Conservation Office (SECO) has not adopted the 2012
IECC. Consequently the recommended amendments to the 2012 IECC have been analyzed 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 IRC. Some amendments below are noted that if /when SECO does by rule adopt the
2012 IECC as the TBEPS, the proposed amendment would be deemed less stringent and therefore would not be
considered a recommended amendment.
**Section C101.4.2 and R101.4.2; change to read as follows:
C101.4.2/R101.4.2 Historic Buildings. Any building or structure that is listed in the State or National Register of
Historic Places; designated as a historic property under local or state designation law or survey; certified as a
contributing resource with a National Register listed or locally designated historic district; or with an opinion or
certification that the property is eligible to be listed on the National or State Registers of
Historic Places either individually or as a contributing building to a historic district by the State Historic
Preservation Officer of the Keeper of the National Register of Historic Places, are-exempt-from shall comply with
all of the provisions of this code.
Exception: Whenever a provision or provisions shall invalidate or jeopardize the historical designation or
listing, that provision or provisions may be exempted.
(Reason: This is less restrictive than the legislative mandates. It is reasonable to expect compliance with duct
sealing, replacement lighting and the installation of insulation, for example, when possible.)
**Section C102/R102; add Section C102.1.2 and R102.1.2 to read as follows:
C102.1.2/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.
5
(Reason: this amendment is added to allow alternative compliance in accordance with Texas HB 1365, 76th
Legislature.)
* *Section C202 and R202; add the following definition:
GLAZING AREA. Total area of the glazed fenestration measured using the rough opening and including sash,
curbing or other framing elements that enclose conditioned space. Glazing area includes the area
of glazed fenestration assemblies in walls bounding conditioned basements. For doors where the daylight
opening area is less that 50 percent of the door area, the glazing area is the daylight opening area. For all other
doors, the glazing area is the rough opening area for the door including the door and the frame.
(Reason: Since the window to floor area ratios have been added to the prescriptive tables, it is necessary to
define glazing area.)
** *Section R402.2.2; amend the section to read as follows:
R402.2.2 Ceilings without attic spaces. Where Section R402.1.1 would require insulation levels above R -30
and the design of the roof /ceiling assembly does not allow sufficient space for the required insulation, the
minimum required insulation for such roof /ceiling assemblies shall be R -30. This reduction of insulation from the
requirements of Section R402.1.1 shall be limited to 500 square feet (46 m or 20 percent of the total insulated
- - - - - - , • - • - - - - -. This reduction shall not apply to the U - factor alternative approach in Section
R402.1.3 and the total UA alternative in Section R402.1.4.
(Reason: Retains the current 2009 language to eliminate confusion and limit the area to 500 square feet
maximum)
*** Table R402.1.1 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.)
If /when SECO does by rule adopt the 2012 IECC, this proposed amendment would be deemed less stringent and
therefore would not be considered a recommended amendment.
*** Table R402.1.3 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.)
If /when SECO does by rule adopt the 2012 IECC, this proposed amendment would be deemed less stringent and
therefore would not be considered a recommended amendment.
6
* * *R402.4.1.2 Testing; Add a last paragraph to read as follows:
Testing may only be performed by individuals that are certified HERS Raters or Rating Field Inspectors by
RESNET or Performance Verification Technicians certified by Texas HERO, or other certifications as may be
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 International Residential Code (IRC) and International Energy Conservation Code (IECC)
include 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 unless a detailed air barrier
and insulation inspection has been performed to field verify component criteria. This language puts the regulatory
authority on notice that the testing requires specialized credentials and establishes a conflict of interest baseline).
** *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 Zones 1 and 2, and 3 air changes per hour in Climate Zones 3
through -8. {Remainder of text unchanged)
(Reason: The 2012 IECC will require mandatory door blower testing on each dwelling unit. The visual inspection
is no longer an option to performance testing. This change will give some time for those builders not currently
using a performance approach to adapt construction practices.)
If /when SECO does by rule adopt the 2012 IECC, this proposed amendment would be deemed less stringent and
therefore would not be considered a recommended amendment.
** *R403.2.2 Sealing (Mandatory); Add a last paragraph to read as follows:
Testing may only be performed by individuals that are certified HERS Raters or Rating Field Inspectors by
RESNET or Performance Verification Technicians certified by Texas HERO, or other certifications as may be
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 installed the duct system.
(Reason: The 2012 International Residential Code (IRC) and International Energy Conservation Code (IECC)
include 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 unless a detailed air barrier
and insulation inspection has been performed to field verify component criteria. This language puts the regulatory
authority on notice that the testing requires specialized credentials and establishes a conflict of interest baseline).
*** Section R403.2.2; Amend to read as follows:
R403.2.3 Building cavities (Mandatory). Building framing cavities shall not be used as supply ducts and-- pleas.
Building framing wall cavities in the exterior thermal envelope shall not be used as return ducts
(Reason: Continue the practice in the regions and to insure that the building thermal envelope is not
compromised.)
7
**Section C402.2.9/R402.2; Add Section C402.2.9 and R402.2.13 to read as follows:
Section C402.2.9/R402.2 Insulation installed in walls. To insure that insulation remains in place, insulation
batts installed in walls shall be totally secured by an enclosure 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 batt 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
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 C101.4.3 Additions, alterations, renovations or repairs; add exception #9 to read as follows:
9. Replacement of existing fenestration, provided, however, that the area of the replacement fenestration does
not exceed 25% of the total fenestration area of an existing building and that the U- factor and SHGC will be equal
to or lower than before the fenestration replacement.
(Reason: Provide some level of consideration for existing buildings, matches ASHRAE 90.1 -2010 Exception "g"
to Section 5.1.3.)
If /when SECO does by rule adopt the 2012 IECC, this proposed amendment would be deemed less stringent and
therefore would not be considered a recommended amendment.
