North Central Texas Council of Governments'
Recommended Amendments to the
2000 International Energy Conservation Code
As Amended by the City of North Richland Hills
Section 101.3; amend as follows:
101.3 Compliance. Compliance with this code shall be determined in accordance
with Sections 101.3.1~-and-101.3.2. or 101.3.3.
Add the following item:
101.3.3. Alternative compliance. A building certified through a voluntary
energy performance testing program approved as meeting or exceeding the
provisions ofthis code may be deemed to comply with the requirements ofthis
code.
(Reason: This amendment would encourage participation in above-code programs
and provide an attractive alternative path for unconventional builders who are
committed to quality and efficiency, but concerned about mechanics of code
compliance. NCTCQG will arrange advisory review of such programs.)
Section 302.1; Replace blank Table 302.1 Exterior Design Conditions with the
following:
CONDITION
Winter a, design dry-bulb (OF)
Summera, design dry-bulb COF)
Summer a, design wet-bulb (OF)

Delete note "a" and replace with thefollowing:
a. These values are from ASHRAE Handbook of Fundamentals for Dallas/Ft.
Worth International Airport 99.6% Winter DB, 0.4% Summer DB, and 0.4%
Summer WB: and from Local Climatological Data for Dallas-Ft. Worth published
by the National Climatic Data Center, National Oceanic and Atmospheric
Administration. These values are for the purpose of providing a uniform basis of
requirements for North Central Texas. This will not preclude licensed
professionals from submitting design analyses based on site measurements or
published data more specific to the building site. Adjustments shall be permitted
to reflect local climates which differ from the tabulated values, or local weather
experience determined by the code official.
(Reason: One of the references in note "a" is in error. The 1997 ASHRAE
Handbook of Fundamentals no longer publishes the design temperature tables in
the format assumed by this reference. The main purpose of this change, however,
is to provide typical design data for the NCTCOG region for ease of reference
within this code.)
Delete Figures 302.1 (1-43, 45-51).
(Reason: There is no need to reference the maps of other states.)
Section 502.1.1; delete exception #2 and substitute thefollowing:
2. Buildings located in Climate Zones 1 through 9 as indicated in Table 302.1. If
a vapor retarder is installed, it is recommended that it be installed on the warm-in-
summer side ofthe thermal insulation.
(Reason: This would eliminate the requirement of a vapor retarder throughout the
NCTCOG region. Eliminating vapor retarders in hot and humid climate zones is
consistent with the recommendation of most building scientists. Although the
omission of a vapor barrier is recommended, it is not the intent ofthe amendment
to prohibit the installation.)
Section 502.1.3; delete item #2:
(Reason: The use of fabricated assemblies to provide air seals creates an
enforcement difficulty in preventing fire hazards due to clearance requirements of
the light fixtures.)
2
------.-----.·--·-_·_____~____.._.__c_~______.__.._____
Section 502.1.5; modify and add exceptions:
502.1.5 Fenestration solar heat gain coefficient. In locations with heating
degree days (HDD) less than 3,500, he combined solar heat gain coefficient (the
area-weighed average) of all glazing fenestration products (illduding thG dfc.cts of
any peÙllall'llt extGl~Or solar shading deviGes) in the building shall not exceed 0.4.
Exceptions:
1. Any glazing facing within 45 degrees of true north:
2. Any glazing facing within 45 degrees of true south which is shaded along its full
width by a permanent overhang with a projection factor of 0.3 or greater.
(Reason: This will allow north facing windows, which do not receive direct solar
radiation, to be exempt from the minimum SHGC requirement; provides a simple
way for south facing windows to effectively achieve summer shade and still
receive some solar heat benefit in. Solar shades are not intended to be utilized to
obtain SHGC requirements due to being non-permanent assemblies.)
Section 502.2; Replace blank Table 502.2 Heating & Cooling Criteria with the
following:
Table 502.2a,g

Delete Note "a" and replace with thefollowing:
a. The above values have been determined for all counties in the North Central
Texas Council of Governments region.
Add Note "g":
g. These requirements apply only to the boundaries of conditioned space. Air
conditioning equipment is recommended, but not required. to be located within
the conditioned space in North Central Texas zones.
Delete Figures 502.2(1-6)
(Reason: This change unifies the requirements for all counties within the North
Central Texas COG. Reference to the graphs is no longer needed when the values
have been specified.)
Section 502.2; Add note to Fig 502.2(7):
All counties within the North Central Texas Council of Governments region are
designated as within the area of very heavy termite infestation probability for
purpose of uniform interpretation of this requirement.
(Reason: This allows for uniform interpretation of the map throughout the area of
the COG.)
Section 502.2.4; Delete prescriptive Tables 502.2.4(1-9) and substitute the
following:
Replace Tables 502.2.4 (1-6) with:
Table 502.2.4(1)

(Reason: This change a) reduces the number oftables to be referenced; b) unifies
envelope prescriptive requirements across all areas within the COG, requiring the
more restrictive values of zones 5b or 6b; and c) eliminates slab edge insulation
requirement. )
Section 503.3.3.3; amend as follows:
All supply and return-air ducts and plenums installed as part of an HV AC air-
distribution system shall be thermally insulated in accordance with Table 503.3.3.3 or
where such ducts or plenums operate at static pressures greater than 2 in. w.g. (500
Pa) in accordance with Section 503.3.3.4.1. Duct insulation products that are
required to meet increased insulation values found in Table 503.3.3.3 ofthe 2001
Supplement to the International Energy Conservation Code are not yet readily
available in the NTCOG region. Until such time as the materials become reasonably
available, the Building Official may authorize alternate materials that substantially
meet these requirements.
(Reason: This change clarifies that requirements for higher pressure ducts are given
elsewhere. These duct systems are typically associated with commercially sized
equipment. This change will be included in the IECC 2001 Supplement.)
5
Section 503.3.3.4; amend subsections as follows:
503.3.3.4.1 High- and medium-pressure duct systems. All ducts and plenums
operating at static pressures greater than 2 in. W.g. (500 Pa) shall be insulated and
sealed in accordance with Section 803.2.8. Iligh µressurG and mediwll pressure
dDucts operating at static pressures in excess of3 in. w.g. (750 Pa) shall be leak
tested in accordance with SMACNA IlV AC Air Duct LcakagG Test Manual with a
rate of air leakage 110t to GXGGGd the maximum rate spcÚfied in that standard. Section
803.3.6. Pressure classifications specific to the duct system shall be clearly indicated
on the construction documents in accordance with the International Mechanical
Code.
503.3.3.4.2 Low pressure duct systems. All longitudinal and transverse joints,
seams and connections of low-pressure supply and return ducts operating at static
pressures less than or equal to 2 in. W.g. (500 Pa) shall be securely fastened and sealed
with welds gaskets, mastics (adhesives), mastic-pIus-embedded fabric systems or
tapes installed in accordance with the manufacturer's installation instructions.
Pressure classifications specific to the duct system shall be clearly indicated on the
construction documents in accordance with the International Mechanical Code.
(Exception is unchanged)
(Reason: These changes, which will be included in the 2001 Supplement to the IECC,
are necessary because the term "low" and "high" have been discontinued by
SMACNA. The modification more clearly delineates the static pressure classification
of duct systems in question.)
Section 802.2; Replace blank tables 802.2 (1-4) with the completed tables provided
as follows. Delete tables 802.2 (5-37).
(Reason: This change provides a unified set of prescriptive requirements for all areas
within the NCTCOG area based upon the most restrictive zone's requirements (5b or
6b). The deleted tables are not necessary after tables 1-4 are completed, and
eliminates data irrelevant to the NCTCOG region.)

public review ASHRAE 90.1 - 1999, Space Control. This "zoning" is especially
relevant for after-hours employees in office spaces.)

reference standard for commercial construction.)
