According to the latest figures from the U.S. Department of Energy, residential buildings account for 21 percent of primary energy use in the United States and 35 percent of the nation's electricity use. A significant portion of this energy could be saved by increasing the energy efficiency of new and existing homes.
The Alliance has several programs providing energy-efficiency resources to builders. Among them are the Building Codes Assistance Project and the Efficient Windows Collaborative. The links below provide more information about energy efficiency and home building.
