DOE Issues Final Determination On Standard 90.1-2007
The U.S. Department of Energy has issued its final determination that ASHRAE Standard 90.1-2007 achieves greater energy efficiency than its predecessor edition. DOE estimates that Standard 90.1-2007 achieves national source energy savings of approximately 3.9% of commercial building energy consumption compared to Standard 90.1-2004. Additionally, DOE has determined site energy savings are estimated to be approximately 4.6% compared to Standard 90.1-2004.
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 commercial building code regarding energy efficiency and made a determination as to whether to update their code to meet or exceed the Standard 90.1-2007. States must provide these certification statements by July 20, 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 has also published a final determination on the 2009 IECC and a preliminary determination on ASHRAE Standard 90.1-2010.
