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.
