What is the HERS Index©?
The Home Energy Rating System or HERS Index is a nationally recognized industry standard of measuring a home’s energy use. The score is created by an energy model that inputs u-values for major envelope components as well as mechanical systems. A home with a rating of 100 met the IECC 2004 energy code. Many older homes have ratings in the 130s and even higher. Current energy code requires at least a HERS of 85, or 15% reduction in energy use than a new home built in 2004. A net-energy zero home would have a HERS index of 0.
A HERS home energy rating, conducted by a certified RESNET Home Energy Rater, is an energy performance assessment of a home. It provides a computerized simulation analysis utilizing RESNET Accredited Rating Software to calculate a rating score on the HERS Index. The report will also contain a cost/benefit analysis for the recommended improvements and expected return on investment.
Who is RESNET©?
The Residential Energy Services Network (RESNET©) is an independent, non-profit organization founded in 1995 to help homeowners reduce the cost of their utility bills by making their homes more energy efficient. This organization developed the Home Energy Rating System (HERS©) Index, a standard of home efficiency recognized by the U.S. Department of Energy, the U.S. Environmental Protection Agency, and the American mortgage industry. RESNET© also trains and certifies HERS© home raters.
How is the HERS Index© measured?
A home’s HERS Index© is determined by a RESNET© certified rater, using standardized procedures developed by RESNET© in collaboration with the U.S. Department of Energy, the U.S. EPA, and the American mortgage industry for inspecting, testing, and conducting a computer analysis of the energy performance of a homes.
Why should I be interested in HERS Index© score for a home?
The HERS Index© score can be used to compare the energy efficiency of homes. The lower the HERS Index© score, the more energy efficient the home. When comparing similar sized homes, a home with a HERS Index© of 80 is 33%* more efficient than a home with a HERS Index© of 120 and would expect to spend 33% less in energy costs.
Many appliances are now labeled “Energy Star,” isn’t that enough to lower my energy costs?
Like your car, the more efficient the home, the lower your utility costs will be every year. Just because a home or appliance has an “Energy Star” label doesn’t mean you are going to get the most for your money. The real test for a new home in 21st Century efficiency is the HERS Index©.
What if other homebuilders offer a big list of “efficiency features,” but no HERS© rating?
A big list of features may look good, but will they really save you money? Don’t get lost in the hype. Check the HERS Index© first to really see how efficient the home really is. Don’t put your faith in a list of “efficiency features” without knowing how much you could really end up paying!
*A HERS Index© of 120, less a HERS Index© of 80, equals 40 points. 40/120=33.3%
