The U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Agriculture (USDA) determined last week that the adoption of the 2009 International Energy Conservation Code (IECC) for single family homes and the 2007 edition of ASHRAE 90.1 for multifamily buildings will have zero negative impact on the affordability and availability of certain HUD- and USDA-assisted housing, specified in section 481 of the Energy Independence and Security Act of 2007 (EISA). 2009 IECC and ASHRAE 90.1-2007 requirements will be applied to all covered programs upon completion of this determination by HUD and USDA, and the previously published energy efficiency determinations by DOE.

To learn how adoption of the 2009 IECC or ASHRAE 90.1-2007 new construction standards described in the determination will take effect, read Final Affordability Determination-Energy Efficiency Standards, which is in the current issue of the Federal Register.
