Building America is a private/public partnership that develops energy solutions for new and existing homes. The Building America project combines the knowledge and resources of industry leaders with the U.S. Department of Energy's technical capabilities. Together, they act as a catalyst for change in the home-building industry.
In February of 2008, Building America launched the “Builder Challenge”, a program that enlists builders to work toward the goal of zero energy homes by 2020. They also rolled out the “E-Scale”, an easy to read chart to help homebuyers quickly identify the energy efficiency of a new home. It is being compared to the mpg stickers found on new cars.
