The HERS Index system measures a home's energy efficiency, much like what a MPG rating does for a car. Outlined on each Certificate (which comes with every condominium), the HERS Index Rating will provide the homeowner with an estimated annual energy cost. These estimates involve analysis of the heating and cooling systems, water heating, lighting, appliances, all exterior walls (both above grade and below), floors over unconditioned spaces (like garages), ceilings, roofs, attics, foundations, crawlspaces, windows, doors, vents, ductwork, and thermostats.
A certified RESNET HERS Rater will evaluate the energy efficiency of the condominiums, and a HERS Index Score will be determined for each unit. Like a MPG score for a car, the lower the number, the more efficient the home.
The U.S. Department of Energy has identified that a typical "resale or existing" home scores 130 on the HERS Index, while a standard new home built to minimum code comes in with a rating of 100.
A HERS Index Rating does several things:
* It provides a homeowner with an estimate of energy costs for their new home, even before purchase.
â€¢ Homeowners have a way to compare the energy efficiency of homes they are considering for purchase (provided competing builders utilize the Rating system).
â€¢ A Rating provides transparency and better defines what the builder is specifically doing to achieve a certain level of energy efficiency, versus just telling a customer that a home is efficient with nothing to back up that statement.
â€¢ It shows a builder's commitment to energy efficiency and sustainability, which is not only good for our generation, but for future generations as well.
â€¢ If a homeowner wants to eventually sell their home, a low HERS Index Score can result in a higher resale price.
