DOE Officially Determines ASHRAE Standard 90.1-2010 Saves More Energy than 2007 Version
DOE Officially Determines ASHRAE Standard 90.1-2010 Saves More Energy than 2007 Version; States Required to Certify Compliance by October 18, 2013
This week the U.S. Department of Energy (DOE) issued its final determination that ANSI/ASHRAE/IES Standard 90.1-2010 Energy Standard for Buildings Except Low-Rise Residential Buildings saves more energy than Standard 90.1-2007. Specifically, DOE found national source energy savings of approximately 18.2 percent, and site energy savings of approximately 18.5 percent, when comparing the 2010 and 2007 versions of Standard 90.1.
Please note: When comparing Standard 90.1-2010 with the 2004 version, site energy savings for Standard 90.1-2010 are 32.6 percent and energy cost savings are 30.1 percent (without plug loads). With plug loads, site energy savings are estimated at 25.5 percent, and energy cost savings are 24 percent.
This week’s DOE determination compared Standard 90.1-2010 with the 2007 version.
As a result of this week’s DOE final determination, states are required to certify by October 18, 2013 that that have reviewed the provisions of their commercial building code regarding energy efficiency and updated their code to meet or exceed Standard 90.1-2010. States may request extensions of this deadline from DOE if a state can demonstrate that it has made a good faith effort to comply with this code update.
