Reference is added in R320 for treating of field cuts in compliance with AWPA M4. This is consistent with the requirements in R319. However, in practice almost all preservatively treated wood in the local area is southern pine and Section 6 of M4 says that field treatment of softwood species such as southern pine isn't necessary to provide a good service life. The revisions to R320 are intended to make the section read better and to provide guidance in proper methods of termite protection.) **Section R323.1; change to read as follows: R323.1 General.

Meetinq the requirements of the International Enerqy Conservation Code for residential buildinqs, detached one- and two-familv dwellings. {Remainder of section unchanged} (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 REScheck 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 susceptibilitv to termite damaqe is classified as "verv heavv" accordinq to Table R301.2(1), desiqns ernploving basement or slab exterior insulation capable of harborinq 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.) North Central Texas 2003 IRC amendments 7 March 2004 **Section N1102. I; amend as follows: N1102.1 Thermal performance criteria. The minimum required insulation R-value or the area-weighted average maximum required fenestration U-factor (other than opaque doors which are governed by Section N1102.1.3) for each element in the building thermal envelope (fenestration, rooflceiling, opaque wall, floor, slab edge, crawl space wall and basement wall) shall be in accordance with the criteria in Table N1102.1. Detached one-and-two family dwellings with greater than 44-25-percent glazing area; townhouses with .. . . greater than 25-percent glazing area; p; shall determine compliance using the building envelope requirements of Chapters 4 or 5 of the International Energy conservation Code. (Reason: This amendment is compatible with the amendment to Section N1101.2.1, which increases the allowable glazing area and effectively increases the number of builders who can use the "simplified prescriptive" approach of the IRC.) **Replace Table N1102.1 with: TABLE N1102.1 SIMPLIFIED PRESCRIPTIVE BUILDING ENVELOPE THERMAL COMPONENT CRITERIA MINIMUM REQUIRED THERMAL PERFORMANCE (U-FACTOR AND R-VALUE) a.

MAXIMUM GLAZING U-FACTOR [~tu/(hr.ft~."~)] 0.65 Use of this table is limited to projects where the cathedral ceiling area is limited to one third or less of the total ceiling area. (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 JoisVRoof Rafter Assembly" requirements protect such assemblies from the damage likely to occur if greater amounts of insulation were attempted in such assemblies.) MINIMUM INSULATION R-VALUE [(hr.ftZ."~)/~tu] ***Section N1102.1.6; delete last sentence of exception. (Reason: Slab edge insulation is not recommended in this region.

Anv fenestration with permanently attached screens where the screens have a rated shadinq coefficient of .6 or less. (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 winter; and specifically allows use of solar screens to achieve the shading effect.) ***Table N1103.5; amend as follows: {Remainder of table unchanged.} Cooling Systems Chilled water, refrigerant or brine Amend footnote "b" to read as follows: b.

Piping in solid floors shall be laid in channels in the floor and covered in a manner what will allow access to the piping with a minimum amount of damage to the building. Where such piping is subject to exposure to excessive moisture or corrosive substances, the piping shall be protected in an approved manner. As an alternative to installation in channels, the piping shall be installed in accordance with Section G2415.11 (404.1 1) (Reason: Referencing Section G2415.11 provides CSST piping with outside venting.) **Section 62415.9; change to read as follows: G2415.9 (404.9) Minimum burial depth.
