The U.S. Department of Energy (DOE) supports and participates in the model building energy code development processes administered by the ASHRAE and the International Code Council (ICC). DOE activities include developing and submitting code change proposals, conducting analysis of building energy efficiency and cost savings, and formulating underlying evaluation methodologies. Through participation in model energy code development for both commercial and residential buildings, DOE strives to make cost-effective, energy efficient upgrades to current model codes. DOE is currently developing its proposed changes for the 2018 International Energy Conservation Code (IECC).
DOE activities to improve the energy efficiency of commercial buildings primarily target the International Energy Conservation Code (IECC) and Standard 90.1.
DOE is required by law (the Energy Conservation and Production Act, as amended (ECPA)) to issue a determination as to whether the latest edition of ASHRAE Standard 90.1 (for commercial and multi-family high-rise residential buildings) or the latest version of the International Energy Conservation Code (for low-rise residential buildings) will improve energy efficiency compared to the previous edition of the corresponding standard or code. DOE has one year to publish a determination in the Federal Register after each new edition of the standard/code is published.
