The International Energy Conservation Code (IECC), originally developed in 2000, is a model code adopted throughout the country to establish minimum standards for the energy efficient construction and renovation of residential and commercial buildings. 

Pursuant to NRS 701.220, the Governor's Office of Energy (GOE) is required to adopt the most recently published version of the IECC on a triennial basis. Upon adoption by GOE, local governments shall follow suit and are authorized to adopt amendments and/or provisions which are more stringent then the standards published and adopted.
