DOE Issues Final Determination on 2009 IECC
The U.S. Department of Energy has issued its final determination that the 2009 IECC achieves greater energy efficiency than its predecessor editions. DOE previously published preliminary determinations of these findings in September 2010. DOE estimates that the 2009 IECC achieves 14% greater site energy savings in low-rise residential buildings than the 2006 IECC. The Department also estimated that the 2006 IECC achieves 1% greater site energy savings than the 2003 IECC. The determination concluded that 2003 IECC does not achieve greater energy efficiency than the 2000 IECC.
As required by federal law under the Energy Policy Act of 1992 (EPAct), states are required to file certification statements to DOE that they have reviewed the provisions of their residential building code regarding energy efficiency and made a determination as to whether to update their code to meet or exceed the 2009 IECC. States must provide these certification statements by July 19, 2013. Check OCEAN in the coming days to see states’ progress on complying with this requirement for the most recent commercial and residential energy code determinations published by DOE.
DOE will begin assessing whether or not the 2012 edition of the IECC saves energy over the 2009 IECC in November 2011. DOE has also published a final determination on ASHRAE Standard 90.1-2007 and a preliminary determination on ASHRAE Standard 90.1-2010.
