Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.
Legislation signed in 2009 changed the process of adopting building codes in the state. Previously, the statewide code would only apply to local governments that had not already adopted a code, including less stringent codes. The code now applies to all jurisdictions, but local governments may adopt more stringent codes provided they notify the Office of Energy.
The most recent code references 2012 IECC and ASHRAE 90.1-2007. The new code became effective on July 1, 2015. Under state law, the Nevada State Energy Office must promulgate the most recent version of the IECC every three years.
