DOE establishes ASHRAE/IESNA Standard 90.1-2007 as national reference for federal, commercial buildings
Commercial and high-rise residential buildings, including federal buildings, must now meet requirements in ASHRAE/IESNA’s 2007 energy efficiency standard under recent rulings issued by the United States Department of Energy (DOE) that finds the standard saves more energy than the 2004 version.
ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, has been established by the DOE as the commercial building reference standard for state building energy codes under the federal Energy Conservation and Production Act. As a result, states are required to certify by July 20, 2013, that they have reviewed and updated the provisions of their commercial building code regarding energy efficiency, including a demonstration that the provisions of their commercial building codes regarding energy efficiency meet or exceed 90.1-2007.
