What is the Georgia State Energy Code, and does my remodel trigger it?

Answered by AskBaily Editorial · Updated

Short answer

Georgia adopts the 2021 International Energy Conservation Code (IECC) with Georgia amendments for Climate Zone 3A (warm humid). Envelope R-values, window U-factor/SHGC, duct leakage, HVAC efficiency, and mandatory whole-house mechanical ventilation all apply. Residential scope that disturbs envelope or mechanical systems triggers compliance audit; substantial renovation often forces whole-system upgrade rather than like-for-like replacement.
