The Alliance the Save Energy estimates the following annual savings in the residential and commercial sectors as a theoretical potential, if all states adopted the 2012 IECC in 2012 and achieved full compliance by 2013:
- More than 3.5 quadrillion Btu of annual source energy savings by 2030;
- About $40 billion (real 2008 dollars) annual energy cost savings for consumers and businesses by 2030;
- About 200 million metric tons of carbon dioxide emissions avoided annually by 2030.
These estimates assume savings from all buildings covered by code, including new construction, major renovations and additions among single-family and multifamily homes as well as commercial buildings.
