HERS (Home Energy Rating System) is a scoring system set by the Residential Energy Services Network to measure a home’s energy efficiency and determine if it meets ENERGY STAR guidelines. The lower the HERS index, the more energy efficient the home. A leading third-party Arizona energy consultant and certifier conducted HERS Certification for Dorn Homes.
On average, a Dorn Home scores between 60 and 75 on the HERS scale. Compare this against the older pre-existing home with a HERS score of 130 and it is easy to see how the savings can start adding up. To put this into financial terms, a Dorn Home could save you $10,000 to $20,000 over an ownership period of 10 years when compared to a typical pre-existing home.
