The U.S. Department of Energy (DOE) has issued a determination that ANSI/ASHRAE/IES Standard 90.1-2016 will improve energy efficiency in commercial buildings.
The department’s analysis found that buildings meeting 90.1-2016 would result in national energy cost savings of about 8.2% compared to the 2013 edition of the standard. DOE’s Building Energy Codes Program provides technical support for Standard 90.1 in order to increase energy efficiency and reduce waste in commercial buildings.
DOE is required by federal statute to review each newly published edition of the model code, and issue a determination as to whether the updated code will increase energy efficiency in commercial buildings. States are required to review their commercial building energy codes within two yearsfollowing an affirmative DOE determination, and certify that their codes meet or exceed the updated edition of Standard 90.1.
DOE also provides technical assistance to states submitting energy code certifications and requests for deadline extensions.
