The U.S. Department of Energy says that in a typical residential or commercial building, about 42 percent of energy is lost through doors, roofs, attics, walls, floors, and foundations.

To address these energy losses, the Energy Department is investing $9 million in building envelope technologies, including high-efficiency windows, roofs, and heating and cooling equipment.
