Status of State Energy Code Adoption
ATTENTION: DOE has updated the way it tracks adoption, resulting in a more advanced characterization of state energy codes. As of September 2016, adoption is tracked based on a quantitative analysis of energy savings impacts within a given state. This provides a greater level of accuracy and replaces the previous approach, which was comprised of a simpler qualitative review of state code titles and provisions. Learn more.
Building energy codes will save U.S. home and business owners an estimated $330 billion and 6.2 billion metric tons of avoided carbon dioxide emissions through 2040. Learn more.
This map reflects state commercial codes in effect as of 4/1/16, with the exception of MA, NY, and TX whose recently updated codes are already reflected in the map. Updates to CT will be reflected in the next update.
DOE tracks the adoption of energy codes across the U.S. for commercial and residential buildings. More information is available, including additional background on the methodology, as well as state-specific analysis and characterizations. Learn more.
