Application of ANSI/ASHRAE/IES standard 90.1-2010 could slash energy use

Use of ANSI/ASHRAE/IES Standard 90.1-2010, published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Atlanta, can result in buildings that use more than 30 percentless energy than those designed to the 2004 standard, according to the Pacific Northwest National Laboratory. The laboratory performed an energy modeling analysis under contract with the U.S. Department of Energy’s Building Energy Codes Program.

“The 30 percentgoal, set by DOE, was very challenging to reach,” said Bing Liu, senior research engineer at the Richland, Wash.-based PNNL and the one credited with the idea of the progress indicators. “It’s a huge change that has changed the expectation of other building energy efficiency codes,” added Liu, who served on 90.1’s mechanical subcommittee, according to a Feb. 18 GreenSource report.
