Standard 90.1-2007 Established as National Reference Standard for Federal, Commercial Buildings by DOE

Commercial and high-rise residential buildings, including federal buildings, must now meet requirements in the ASHRAE/IES 2007 energy standard after rulings issued by the Department of Energy.

Prior to the new rules, federal and commercial buildings had to meet requirements in the 2004 standard.

ANSI/ASHRAE/IES 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.

The DOE also has issued a rule that requires new federal buildings, for which the design for construction begins on or after Oct. 11, 2012, to meet the requirements of 90.1-2007.
