Building Energy Standards Program: Preliminary Determination Regarding Energy Efficiency Improvements in the Energy Standard for Buildings, Except Low-Rise Residential Buildings, ANSI/ASHRAE/IESNA Standard 90.1-2007

The Department of Energy (DOE) has preliminarily determined that the 2007 edition of the Energy Standard for Buildings, Except Low- Rise Residential Buildings, American National Standards Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Illuminating Engineering Society of North America (IESNA) Standard 90.1-2007, (Standard 90.1-2007) would achieve greater energy efficiency in buildings subject to the code, than the 2004 edition (Standard 90.1-2004 or the 2004 edition). Also, DOE has preliminarily determined that the quantitative analysis of the energy consumption of buildings built to Standard 90.1-2007, as compared with buildings built to Standard 90.1-2004, indicates national source energy savings of approximately 3.7 percent of commercial building energy consumption. Additionally, DOE has preliminarily determined site energy savings are estimated to be approximately 4.4 percent. If these determinations are finalized, States would be required to certify that they have reviewed the provisions of their commercial building code regarding energy efficiency, and as necessary, updated their code to meet or exceed Standard 90.1-2007.
