The adoption of model energy codes presents a significant opportunity to save energy in residential and commercial buildings.

On July 25, 2017, the U.S. Department of Energy (DOE) issued a preliminary determination that ASHRAE 90.1-2016 would achieve greater energy efficiency in buildings subject to it. The DOE estimates national savings in commercial buildings of approximately 8.2 percent for energy cost, 7.9 percent for source energy, and 6.7 percent for site energy.

In 2015, the DOE issued a determination that the 2015 International Energy Conservation Code (IECC) would achieve greater energy efficiency in buildings subject to it. It estimated savings in residential buildings of approximately 0.73 percent for energy cost, 0.87 percent for source energy, and 0.98 percent for site energy.

The DOE tracks these benchmarks to determine overall effectiveness.

Nearly every state in the South has adopted, or is in the process of adopting, an updated state energy code. Florida, Georgia, North Carolina, and Virginia are currently in the energy code update process.
