Get Georgia Residential Energy Code Compliance Certificate

As of January 1, 2020, Georgia's new energy code is the 2015 IECC + 2020 GA Supplements and Amendments, which supersedes the 2009 IECC (with 2011 GA Supplements and Amendments). Georgia's 2020 energy code brings forward several current amendments and introduces a few new ones.

CFM below 1250 indicates reasonably airtight home. CFM between 1300 to 3000 indicates a moderately leaky home. CFM over 3000 indicates a leaky home that would definitely benefit from sealing the leaks.

Georgia building code requires a blower door test for all new homes as well as renovations where more than 50% of square footage was added. The guidelines put in place 2021 dictate that the building envelope be extremely tight and not to exceed more than 5 air changes per hour at 50 Pascals.

Current code restrictions force builders to put a minimum of R-38 insulation in the attic before the house is qualified to be sold, or inhabited.

Adoption Info The 2020 NFPA 70 (NEC 2020) is the current Georgia State Minimum Standard Electrical Code effective January 1, 2021. It was preceded by the 2017 NFPA 70 (NEC 2017) which became effective on January 1, 2018. GA R&R - GAC - Rule 111-8-40-. 40.

The ACH50 Calculation The formula is the rate of airflow in cfm x 60 minutes in an hour / volume of the home = number of air changes per hour. As an example, a home had a blower door test of 750 cfm and a calculated volume of 12,000 cubic feet. Using the formula, 750 cfm x 60 minutes / 12,000 cu. ft.

The average blower door test result depends largely upon the age of the home, the insulation levels, and the age of the windows and doors. Generally, a new home should test less than 3.5 ACH50, as the insulation levels and efficiency of the windows/doors would make for a fairly airtight home.

The built-in fan blows air into or out of a home or building to create either a positive or negative pressure difference between the inside and the outside of the structure. This pressure difference is typically 50Pa or 1.57 psi for a standard blower door test.

As noted above, the building, one and two family dwelling residential, fire, plumbing, mechanical, gas, electrical, energy, and swimming pool codes are mandatory codes, meaning that under Georgia law, any structure built in Georgia must comply with these codes, whether or not the local government chooses to locally ...

For Georgia homeowners, R-50 is the ideal amount of attic insulation when installing stabilized cellulose insulation.

The 2022 Energy Code encourages efficient electric heat pumps, establishes electric-ready requirements for new homes, expands solar photovoltaic and battery storage standards, strengthens ventilation standards, and more.
