The U.S. Department of Energy (DOE) has established
regulations that require new Federal buildings to achieve at least 30%
greater energy efficiency over prevailing building codes. z
Mandated by the Energy Policy Act of 2005 (EPAct), these standards apply to new federal commercial and multi-family high-rise residential buildings, as well as new federal low-rise residential buildings designed for construction that began on or after January 3, 2007.
Over the course of the next 10 years, the standards are estimated to
save taxpayer’s $776 million dollars (in 2004 dollars) and more than 40
trillion British thermal units of energy, while reducing emissions by an
estimated 2 million metric tons of carbon dioxide.
The standards are based on the American National Standards Institute
(ANSI)/ American Society of Heating, Refrigerating, and Air-Conditioning
Engineers (ASHRAE)/ Illuminating Engineering Society of North America
(IESNA) Standard 90.1-2004 for commercial and high-rise multi-family
residential buildings and the 2004 version of the International Code
Council (ICC) International Energy Conservation Code (IECC) for low-rise residential buildings.
Achieving this level of savings will require Federal agencies and their
design teams to use an integrated design approach for new buildings.
