Ratings and Audits

Energy ratings and energy audits are similar to each other, but have distinct differences. Each deals with a home, but each is designed for different purposes.

Energy Ratings

Energy Ratings are technically called HERS (Home Energy Ratings System) Ratings. Most often, HERS Ratings are conducted on new homes that haven’t been occupied yet. A HERS Rating establishes a HERS Index or score for a home. Though an imperfect analogy, the HERS index is most often described as a “Miles-per-gallon” sticker for a new home. The HERS ratings gives us an estimate of the energy use that an average homeowner should expect for that home. It also allows us to compare the scores of similar homes. HERS Ratings are governed by RESNET (Residential Energy Services Network) Standards and include quality assurance as well as certification for the HERS Rater, the professional performing the HERS Rating.

HERS Ratings can be performed on older homes as well, though this is far less common. The primary reason for doing so is to establish a baseline energy use to compare to when exploring energy retrofit options. This typically is done in connection with an energy efficient mortgage product that incentives a homebuyer to make energy improvements.

Energy audits

Energy audits are far less strictly defined. An energy audit may be quite rigorous or may be quite simple. The purpose for conducting an energy audit is also wide-ranging; from consumers seeking information to utility companies complying with regulatory mandates. Ultimately, an energy audit should deliver some information to a homeowner that enables them to make informed decisions about improving the energy performance of their home.

EnergyLogic performs energy audits only under contract with utility providers.
