The U.S. Department of Energy (DOE) has issued a ruling establishing the American National Standard ANSI/ASHRAE/IESNA 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, as the commercial building reference standard for state building energy codes under the federal Energy Conservation and Production Act.
Issued in an October 19 Federal Register notice, the ruling was taken after preliminary analysis indicated that the 2010 edition bears significant energy savings over the 2007 standard. The energy consumption of buildings built to Standard 90.1-2010, as compared with those built to the 2007 edition, indicates national source energy savings of approximately 18.2 percent of commercial building energy consumption. Additionally, site energy savings are estimated to be approximately 18.5 percent. As a result of the ruling, states are required to certify by October 18, 2013, that they have updated the provisions of their commercial building code regarding energy efficiency to meet or exceed 90.1-2010.
