Examples of Energy-Efficient Homes
- Building America:
- The U.S. Department of Energy's (DOE) Building America Program works with the residential building industry to produce homes on a community scale that use 30% to 50% less energy than standard homes, at little or no increased purchase price. See specific case-study homes.

- The Walnut Creek, California site is a 1578 ft2 single story raised floor foundation home built in 1969 in California's 'transition zone'. Transition zone summer temperatures range from 75-105°F during the day and normally fall to 50-60°F at night; winter temperatures are in the 35-50°F range. The whole-house achieved savings (weather-normalized) for all energy measures was 51% of the energy that was being consumed by the home in the base case year.
- The Stockton, California site is a 2,200 ft2 single story slab-on-grade home built in 1979. The home is located in California's Central Valley, a climate of very hot summers in the 95- 105°F range and winter lows down to freezing. The whole house achieved savings (weather-normalized) for all energy measures was 54.2% of the energy that was being consumed by the home in the base case year.
