49:'s Building America program. Building America research "is expected to achieve cost-neutral Net-Zero Energy Homes by 2020. "Cost-neutral" means that the added first costs of system enhancements (when amortized over a 30-year period) are equal to the monthly energy cost savings that result from these enhancements. While the Building America program develops and field-tests the technologies needed to cost-effectively move to higher levels of efficiency, the Builders Challenge will promote the implementation of proven strategies that builders can implement in any climate region."

The E-Scale allows for an easy comparison between homes, very similar to a MPG sticker for a car but for a home. Homes meeting the Challenge will receive an E-Scale with a Sunburst displaying the E-Scale rating of the home, enabling home buyers to easily compare the energy performance of homes.
