At EDGE Energy, we’re proud to provide home energy rating services to qualify new and existing homes for the ENERGY STAR label, using the Home Energy Rating System (HERS) Index. The HERS Index is a scoring system established by the Residential Energy Services Network (RESNET), and is used to tell homeowners what to expect in annual energy costs, including heating and cooling, hot water, and much more.
A HERS rating will tell you what to expect in annual energy costs with specific information about your heating and cooling costs, hot water costs, and much more. Additionally, you may qualify for an Energy Efficient Mortgage (EEM) which will give you more buying power and potentially better terms.

A home energy rating involves an analysis of your construction plans for a home and onsite inspections. Based on your construction plans, our own Home Energy Rater will use an energy efficiency software package to perform an energy analysis of the design of your home. This analysis yields a projected, pre-construction HERS Index.
Upon completion of the construction plan review, we’ll work with you to identify the energy efficiency improvements needed to ensure your house will meet ENERGY STAR performance guidelines. Our rater will then conduct onsite inspections, typically including 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 home.
A home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net-zero energy home scores a HERS Index of zero. The lower a home scores on the HERS Index, the more energy efficient it is compared to the HERS Reference Home. Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. Thus, a home with a HERS Index of 85 is 15% more energy efficient than the HERS Reference Home, and a home with a HERS Index of 80 is 20% more energy efficient.
Look For the ENERGY STAR label. ENERGY STAR qualified homes are at least 30% more energy-efficient than homes built to the national energy code. Even in states with rigorous energy codes, the U.S. Environmental Protection Agency (EPA) ensures that ENERGY STAR remains the symbol for truly energy-efficient performance. EDGE Energy works with ENERGY STAR Builders to verify and test construction of new homes from start to finish.
An ENERGY STAR Builder will be able to provide you with a certified HERS Rating and to help you obtain an Energy Efficient Mortgage.
All of our energy raters are certified by HERS (Home Energy Rating System) and RESNET® (Residential Energy Services Network), affiliates of the United States Department of Energy (DOE) and Energy Star programs.

Edge Energy responded quickly to my inquiries and provided clear answers. The technicians who oversaw the installation process were professional and I learned a great deal while interacting with them.
I was completely satisfied by Edge Energy. They have consistently designed and reliably installed strong performance energy innovations for my home. Indeed the only reason that I installed SunPower panels was due to their recommendation.
Edge Energy was excellent all around. Knowledgeable, friendly, willing to troubleshoot and correct issues that arose during the installation process.
Edge Energy clearly prefers installing SunPower systems. They were professional and technically informed. They were reasonable and accommodating with contractural matters. The installation crews were polite and courteous. They did neat work and were very competent. They were extremely responsive to address problems that arose. I would recommend them without reservation. They put a good face on SunPower.
A friend recommended SunPower and Edge Energy and my expectations were exceeded. I have and will recommend both companies.
