Frequently Asked Questions
What is the HERS Index?
The HERS Index is a national rating system used to measure energy efficiency. In a nutshell, the lower the home’s HERS score, the higher its energy efficiency. In many areas, HERS-rated homes are becoming a consumer expectation as more consumers become aware of the benefits of energy efficient homes – including lower utility bills, increased comfort and safety, improved indoor air quality, greater energy security, diminished environmental impact and increased resale value. Homebuyers are beginning to demand these homes in the same way they expect certain features, such as efficient appliances and “smart” technology.
The U.S. Department of Energy estimates that houses built in line with today’s energy code use 30 percent less energy than older homes. Many builders today are building homes that use 70 percent less energy than existing homes. HERS raters, hired by builders to assess a home’s energy efficiency, are a valuable resource to builders. But HERS raters are not one-size-fits-all, and builders need tools and guidance to help them select the right rater for their ongoing needs.
How does a builder that hires an EnergyPro Exchange member benefit?
Large construction firms with multiple divisions in disparate locations tend to hire local providers to achieve cost efficiencies. At the same time, they must constantly seek ways to maintain consistency of quality, meet building codes and standards, and mitigate risk and liability – all with an eye toward maintaining their company brand and reputation for building solidly built, beautiful homes. Of course, all of this takes place in the context of running a business and paying close attention to the bottom line.
A builder with multiple divisions may hire 25 different HERS raters – and will unfortunately get 25 different results. When this happens, quality assurance as a company standard quickly gets compromised. There are many examples illustrating the frustration builders experience with the state of consistency and quality among their HERS raters. The need to gain consistency, elevate quality and ensure integrity is a pressing issue for quality-conscious builders
