DOE Issues Preliminary Determination On Standard 90.1-2010
The U.S. Department of Energy has issued a preliminary determination that ASHRAE Standard 90.1-2010 achieves greater energy efficiency than its predecessor edition. DOE estimates that Standard 90.1-2010 achieves national source energy savings of approximately 18.2% of commercial building energy consumption compared to Standard 90.1-2007. Additionally, DOE has determined site energy savings are estimated to be approximately 18.5% compared to Standard 90.1-2007.
As required by federal law under the Energy Policy Act of 1992 (EPAct), within two years of the publication of the final determination, 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 90.1-2010. Check OCEAN in the coming days to see states’ progress on complying with current EPAct requirements for the most recent commercial and residential energy code determinations published by DOE.
Comments on the preliminary determination must be provided by August 19, 2011. DOE has also published a final determination on the 2009 IECC and a final determination on ASHRAE Standard 90.1-2007.
