Sept. 2, 2011: ASHRAE Standard 90.1 Established as National Reference Standard
ATLANTA — 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 U.S. 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. DOE also 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.
