The adoption of model codes presents a significant opportunity to save energy in residential and commercial buildings. The U.S. does not have a national energy code or standard, so energy codes are adopted at the state and local levels of government. Through the Building Energy Codes Program (BECP), DOE provides technical assistance  to state and local governments to help facilitate the adoption process . This support also includes tracking state adoption status , coordinating activities among stakeholders, and technical analysis.
For more information on the DOE role in the adoption of building energy codes, visit the About  section of this website.
Energy code adoption processes vary, depending upon how the code is adopted and implemented at statewide or local levels.
