Georgia Energy Code 2020
Applied Commercial Lighting Control

Stay up to date with Georgia Energy Code 2020 application solutions for commercial lighting. Support for a basis of design is provided by SESCO Lighting Georgia and Legrand WattStopper.

Georgia Energy Code 2020 was adopted January 1, 2020. The energy code commercial lighting control sections follow IECC2015 without additional Georgia amendments.

See application basis of design references below. For any Georgia application questions, reach out to Adam Rixey, PE at SESCO Lighting Georgia.
