Georgia’s Energy Standards Are Getting Smarter
In recent years, Georgia has made significant strides toward improving home energy efficiency. The state’s adoption of the 2015 International Energy Conservation Code (IECC)—enforced by the Georgia Department of Community Affairs (DCA)—sets higher standards for how homes are built and how HVAC systems are tested.
These updates ensure that homes are more efficient, comfortable, and affordable to operate, but they also place new responsibility on builders and homeowners to verify performance through duct leakage testing.
What the Code Requires
Under the 2015 IECC, any ductwork located outside the conditioned space—such as in attics, crawlspaces, or garages—must be tested for total leakage.
The test measures air escaping from the duct system when it’s pressurized to 25 Pascals, and the results are expressed in CFM25, or cubic feet per minute of air leakage.
To meet Georgia’s standard:
âž¡ï¸ Total duct leakage must not exceed 6 CFM per 100 square feet of conditioned floor area.
In simple terms, this means your home’s duct system must be extremely tight to prevent energy loss, improve comfort, and ensure your HVAC system operates at peak efficiency.
Rebates, Comfort, and Compliance
Beyond code compliance, duct testing offers tangible benefits:
-
Lower Energy Bills: Sealed ducts reduce wasted air and energy loss.
-
Improved Comfort: Balanced airflow keeps every room at the right temperature.
-
Cleaner Air: Fewer leaks mean less dust, humidity, and allergens entering your home.
-
Rebates & Incentives: Many utility companies offer rebates for homes that pass duct testing and efficiency upgrades.
