The National Association of Homebuilders talks the talk of caring about home energy efficiency, then fights bitterly to prevent any helpful green legislation. Will the real NAHB please stand up?

Back on March 30, a fluff piece from the National Association of Home Builders (NAHB) appeared in my inbox under the heading “New Homes Increasingly Offer Efficiency, Sustainable Features.” It was a retread message generated by the public affairs department, giving lip service to the Association’s claim of support for sustainable building practices and energy efficiency.

Energy Code Information: The state’s Construction Code Advisory Council approved a draft energy code based on the 2012 IECC. It then moved to a review by the state’s Department of Labor and Industry. A public comment period was held earlier this year, though the state first has to work through the issue of residential sprinklers. Once they finally get to the energy code discussion, they will review the following amendments proposed to both the commercial and residential codes:

Commercial: The IECC commissioning requirements were incorporated into ASHRAE 90.1-2010, so there is consistency between the code and standard.

Residential: Wall insulation R-value is R-21 for the prescriptive table, while the U-value table remains the same as it was. Ventilation requirements have been increased to balanced ventilation (cannot use exhaust or supply).Two options for basement wall insulation: R-15 continuous or R-10 exterior insulation; however, 2.5 ACH50 must be proven.Elements to ensure basement walls are waterproofed, which helps mitigate moisture damage.
