Energy Codes

LB 405, which updates the Nebraska Energy Code from the 2009 IECC to the 2018 IECC and ASHRAE 90.1-2016, was passed by the state's Unicameral Legislature on May 2, 2019 and signed by the Governor on May 8, 2019.

The 2018 IECC code goes into effect July 1, 2020.

If your town or county has not adopted an energy code or does not wish to adopt an energy code, the Nebraska Department of Environment & Energy, Planning & Aid Division will enforce the code in your jurisdiction.
