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 went 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.

REScheck & COMcheck

REScheck is a computer software that makes it easy for designers, builders, and contractors to determine whether a new residential (which includes groups R-2, R-3, & R-4 three stories or less) building meets the building thermal envelope requirements of the 2018 IECC or other selected code. It is a simple UA tradeoff calculation that allows individual components of a building to be customized to the builders’ needs while keeping the entire building at or above the code requirements. The REScheck software can be found on the Energy Codes REScheck webpage.

COMcheck is a computer software for commercial energy code compliance that makes it easy to ensure energy code compliance with the 2018 IECC or ASHRAE 90.1. The COMcheck software can be found on the Energy Codes COMcheck webpage.

 

ACCA Manual J

ACCA Manual J is listed in the 2018 IECC for heating and cooling load calculations for residential structures. A load calculation should be performed for all new buildings. Rule-of-thumb sizing and other less scrupulous methods should not be used, as heating and cooling loads have changed dramatically over time with improved energy codes and these methods commonly lead to oversized equipment.
