Q: What is a home energy rating?

A: The home energy rating is a standard measurement of the home's energy efficiency similar in concept to gas mileage ratings for cars. An energy rating allows a home buyer to easily compare the energy costs for the homes being considered.

Q: What is involved in a home energy rating?

A: Home energy ratings involve an on-site inspection by a residential energy efficiency professional - a home energy rater (aka HERS Rater). Home energy raters are trained by Everblue and certified by RESNET.

The home energy rater inspects the home and measures its energy characteristics, such as insulation levels, window efficiency, wall-to-window ratios, heating and cooling system efficiency, and the solar orientation of the home. Performance testing, such as a blower door test measuring door and duct leakage may be used.

All of the data is input into an energy model that provides the home with a rating, or score, which quantifies the efficiency of the home with a single and easy to understand number. The home receives a point score between 1 and 100, depending on its relative efficiency. The rating also provides an estimate of annual utility costs. A homeowner who wants to upgrade their home’s efficiency can then use the model to predict the savings from different energy saving improvements.

Q: Can I trust the results of a home energy rating?

A: Home energy ratings must meet the stringent standards developed by RESNET. Raters must abide by a code of ethics, rating standards of practice, and most disclose all financial interests to the client. The mortgage industry recognizes the rating to qualify for an energy efficient mortgage.

Q: What can I do with an energy rating?

A: The energy rating provides the following benefits:

  • When buying a home a rating allows you to compare homes according to their energy efficiency.
  • A rating allows you to know the energy performance of your home and identifies cost effective improvements that you can make to increase your comfort and home's performance..
  • A rating is required to qualify the home for an energy efficient mortgage.
  • A rating is required for a home to be labeled as ENERGY STAR.
