The U.S. Department of Energy (DOE) has issued a final determination that ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings, will improve energy efficiency in commercial buildings compared to the previous version of the standard. DOE analysis concluded that buildings meeting 90.1-2016 would result in energy cost savings of approximately 8.3% compared to the 2013 edition. In addition, the latest version provides 7.9% source energy savings and 6.8% site energy savings compared to the 2013 version.
