*'Section N1101.2; amend as follows:
N1101.2.1 Residential Buildings, Type A-1. Compliance shall be demonstrated by--44ef one of the
following:
1. Meeting the requirements of this chapter for buildings with a glazing area that does not exceed 15
percent of the gross area of exterior walls; er
2. Meeting the requirements of this chapter for buildings with a glazing area that is greater than 15
percent but not exceeding 20 percent of the gross area of exterior walls and air conditioning
equipment rated 14 SEER or higher; or
4. Meeting the requirements of the International Energy Conservation Code for residential buildings,
Type A-1.
(Reason: This amendment would increase the number of builders who could use this "simplified
prescriptive" approach of the IRC. It accommodates particularly the move -up and luxury homes with
large glazing areas. The trade-off with air-conditioning is an option under the IECC systems analysis or
MECcheck approach, and is brought into this format for convenience only. Other IECC trade-offs would
also remain available. The intent is to maintain compatibility with the IECC. The intent would include
adjustment of this provision at such future date that the minimum federal equipment standards are raised
to achieve equivalent increases in energy savings.)
Add Section N1101.3.4 to read as follows:
N1101.3.4 Exterior basement or slab insulation. When susceptibility to termite damage is classified as
"very heavy' according to Table R301.211. designs employing basement or slab exterior insulation
capable of harboring termites shall not be utilized.
(Reason: Usage of exterior insulation provides access for termites. This amendment does not preclude
the use of insulating coatings that do not provide termite access or shelter.)
"*Section N1102.1 amend as follows:
N1102.1 Thermal performance criteria. The minimum required insulation R -value or maximum required
U -factor for each element in the building thermal envelope (fenestration, roof/ceiling, opaque wall, floor,
slab edge, crawl space wall and basement wall) shall be in accordance with the criteria in Table

Residential building, Type A-1, with greater than 425 -percent glazing area; residential buildings, Type
A-2, with greater than 25 -percent glazing area; and any building in climates with HDD equal to or greater
than 13,000; shall determine compliance using the building envelope requirements of the International
Energy Conservation Code.
(Reason: This amendment corrects an error in the section and is compatible with the previous
amendment increasing allowable glazing area, effectively increasing the number of builders who could
use the "simplified prescriptive" approach of the IRC.)

(Reason: This amendment is compatible with the previous amendments increasing the number of
builders who could use the "simplified prescriptive" approach of the IRC and incorporates the Home
Builder Association prescriptive package proposal. The addition of "Ceiling Joist/Roof Rafter Assembly"
requirements protect such assemblies from the damage likely to occur if greater amounts of insulation
were attempted in such assemblies.)
