The 1992 Energy Policy Act ("EPAct") mandated that all states must review and consider adopting the national model energy standard. The Energy Policy Act of 2005 specifies the most current model energy codes (IECC 2009, ASHRAE 90.1 -2007). Energy codes can vary greatly from state to state, and even from edition to edition of codes developed by the same authority. For information on the status of codes in a given state, please select a state from the list below:

The Energy Policy Act requires states to certify that their commercial building energy codes meet or exceed the stringency of Standard 90.1-2007 within two years of the July 20, 2011 determination issued by the Department of Energy - meaning action must be taken by July 20, 2013.

NOTE: This map reflects only mandatory statewide commercial codes currently in effect. States that have adopted new codes that are not yet effective are noted with an asterisk (*).
