RESNET EnergySmart Builder

RESNET Energy Smart Builders are committed to increasing the energy performance of the homes they build. These energy efficient homes are more affordable to maintain, more comfortable and have a higher value compared to regular homes. The efforts of these leading builders benefit consumers, the environment, the local economy and our national security.

Energy Smart Builders are committed to having all of their homes energy rated following RESNET's stringent standards, and marketing their homes' HERS Index Score. The RESNET HERS Index is the industry standard by which a home's energy efficiency is measured (learn more about the HERS Index). The use of the HERS Index differentiates homes built by RESNET EnergySmart Builders from other homes for sale in the market. Over 1.5 million homes have been rated on the HERS Index since 1995.
