A HERS (Home Energy Rating System) rating is a standard measurement of a home’s energy efficiency.  HERS ratings are regulated and certified under the administration of the Residential Energy Services Network (RESNET).  HERS ratings involve an on-site inspection of a home by a certified residential energy efficiency professional, a home energy rater.   BLUEGILL Energy Management has certified HERS raters on staff.   Our HERS raters are trained and certified by RESNET.

The data gathered during a HERS rating is input into a computer program and translated into points. The home receives a point score between 1 to 100, depending on its relative efficiency. An estimate of the home’s energy costs is also provided. The home’s energy rating is then equated to a Star rating ranging from a 1 Star for a very inefficient home to a 5 Star for a highly efficient home. Along with the rating sheet, a home owner receives a report listing cost-effective options for improving the home’s energy rating.

One of the major differences between a home energy rating and an energy audit or weatherization assessment is that the rating is a recognized tool in the mortgage process. Home energy ratings are valuable to the housing industry and can be utilized in a variety of ways.
