This map reflects only mandatory statewide residential energy codes currently in effect.
In instances where a state has developed its own code, the maps approximate its energy efficiency in terms of the national model codes. Every effort is made to ensure that they are accurate and up-to-date. If you have any questions or comments about the maps, please contact us.
