The new International Energy Conservation Code (IECC), expected to be ready for adoption later this year, provides both residential and commercial builders more flexibility in making their projects more energy efficient and for the first time includes provisions related to electric vehicles, as well as optional paths to reach net zero energy consumption.
IECC is the model code that local governments use to develop their own building requirements and is updated every three years. Members of the International Code Council, primarily local and state government and building officials, voted on the 2021 update in November, and preliminary results were posted in December.
