New Energy Department Rule Boosts Efficiency on Federal Buildings

July 10, 2013

The Energy Department on July 9 published a new rule requiring new federal buildings to meet higher energy efficiency standards. The rule applies to buildings for which design begins on or after one year after publication in the Federal Register. It updates the baseline federal commercial standards to the 2010 version of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 90.1, which the Energy Department determined would save 18.2% more energy in commercial buildings than the 2007 version of Standard 90.1.

The ASHRAE Standard 90.1 is developed through an American National Standards Institute consensus process that involves industry, building owners, designers, and government. The process includes extensive public review and comment on each change to Standard 90.1. See the rule in the Federal Register.
