The DOE is seeking applications to further building science research under the Building America Program, a partnership sponsored by the U.S. Department of Energy that conducts research to find energy efficient solutions for new and existing housing that can be implemented on a production basis, with the goal of developing cost effective Net Zero Energy Homes by 2020. Zero Energy Homes combine state of the art, energy efficient construction and appliances with commercially available renewable energy systems such as solar water heating and solar electricity, and can be designed and constructed to produce as much energy as they consume annually. The primary goal is to enable industry to adopt systems engineering approaches to the design and construction of a large portion of all new housing.
