HERS..

What is a HERS Rating?

 

A Home Energy Rating involves an analysis of your home’s construction plans and on-site inspections. Based on your home’s design, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design. This analysis yields a projected, pre-construction HERS Index. Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet ENERGY STAR performance guidelines. The rater then conducts onsite inspections, ie: a blower door test to test the leakiness of the house and a duct test to test the leakiness of the ducts. Results of these tests, along with inputs derived from the plan review, are used to generate the HERS Index score for your new home.  One of the qualified members of America’s Network Realty Group will be able to explain these ratings for you.  Visit our website: www.kstrealty.com, to find an abundance of information and homes to meet your criteria.

 

RESNET ratings provides a relative energy use index called the HERS to help you buy a better home. A HERS Index of 100 represents the energy use of the American Standard Building and an Index of 0 (zero) indicates that the home you’re buying uses no net purchased energy. Most homes in the Dunwoody, Chamblee and Norcross areas, meet this criteria.

There are 2 types of ratings to look for in your new home:

  • Projected ratings - Ratings performed prior to the construction of a home or prior to the installation of energy improvements to an existing home.
  • Confirmed ratings - Ratings completed using data gathered from an on-site inspection, which could include performance testing of the home.

Confirmed ratings involve an on-site inspection of a home by a residential energy efficiency professional, a home energy rater. Home energy raters are trained and certified by a RESNET accredited home energy rater training provider. Check our website:  www.kstrealty.com to allow us to assist you in finding that rater.

The home energy rater reviews the home to identify its energy characteristics, like:  insulation levels, window efficiency, wall-to-window ratios, the heating and cooling system efficiency, the solar orientation of the home, and the water heating system. Performance testing is usually part of the rating.  Most of our homes for sale, specifically in the Dunwoody area, are rated very energy efficient.

The data gathered by the home energy rater is entered into a RESNET accredited computer program and translated into rating score. Your new will receive a score between 1 and 100, depending on its relative efficiency. An estimate of your  home's energy costs is also provided in the report. The home's energy rating is then equated to a Star rating ranging from one star for a very inefficient home to five stars for a highly efficient home. See our website: www.kstrealty.com to get more helpful information on how this can help you in buying and selling your property.
