ASHRAE 90.1

2021 IECC for Lighting Controls

2021 IECC provides the minimum requirements for energy-efficient design of most buildings. IECC standards define the minimum energy efficiency requirements for new construction, as well as new systems installed in existing buildings.

Leviton offers a wide spectrum of lighting and energy control solutions to bring any project up to standard compliance. This reference guide provides examples of common applications, 2021 IECC standard compliance considerations, and Leviton solutions to meet the functionality and standard compliance needs of the space. While 2021 IECC is the latest version of the standard, some states and local municipalities are still using previous versions of IECC, including 2012, 2015, and 2018. Changes that took effect in the 2021 version of IECC are highlighted throughout.
