Utah became the latest state to update its commercial building energy efficiency code from the 2015 International Energy Conservation Code (IECC) to the 2018 IECC in July.
The new code permits the use of the ASHRAE/IES 90.1-2016 standard, giving building owners and design teams an alternative compliance path. Any plans submitted for permitting on or after July 1 are required to follow 2018 IECC new energy code requirements.
The new code provides for improved building envelope performance and reduced air infiltration. Another change is a requirement for occupancy sensor controls for lighting shut off within open plan offices.
The occupancy sensor control shut off time delay was reduced to 20 minutes from 30 minutes. Open plan offices must limit the size of the occupancy sensor-controlled area to separate 600 square-foot zones. When occupancy is not detected in these zones, general lighting must automatically shut off or be reduced by at least 80%.
