Some residential builders in Alabama are already exceeding some of the state’s new energy-efficiency code requirements in their projects.
The Alabama Energy and Residential Codes Board recently adopted new codes aimed at making energy efficiency requirements 30% more efficient than the 2006 International Energy Conservation Code.
The new code promotes the use of Low E glass, mass wall exterior insulation, duct sealing for air handlers, no building cavities as supply ducts, a blower door test to assess air infiltration, and other air-seal-related provisions.
