The Home Energy Rating System (HERS) Index is the INDUSTRY STANDARD by which a home's energy efficiency score is measured. It’s also the NATIONALLY RECOGNIZED system for inspecting and testing a home's energy performance. Please call for a quote. Our cost for the service includes provisional rating to confirmed rating including insulation inspections, blower door, and duct blasting.
Discover what a HERS rating is, why get it and how the index works by using this handy lookup calculator from RESNET:
Use a RESNET HERS rating to see how energy efficient your new home's score can be after completing your energy retrofit. The rating system uses software provided by Architectural Energy Corporation, called REM Rate. The rater is required to enter detailed data on the home being rated, whether the home is new construction or an older home. It is divided into numerous sections including the foundation, basement, walls, roof, windows, mechanical, hot water, insulation, appliances, lighting, renewable energy, and several more. The software calculates the heating and cooling loads, duct tightness, home airtightness, and HVAC efficiency of the home based on testing the input data and issues an index score above 0. A new home built to the International Energy Conservation Code (IECC) 2006 standard has an index score of 100. It is important to note that the lower the score the better. An index of zero means the home is net-zero. Each one-point reduction in the HERS Index corresponds to a 1% in energy consumption as compared to the imaginary reference home. A home with a HERS Index of 60 uses 40% less energy than the code minimum home of the same shape and size. It is important to note that a large home will most likely use more energy than a small home assuming both homes are the same HERS index.
The software system also issues reports to the homeowner that include IECC and ENERGY STAR compliance. These reports are important as they are required by municipalities that have adopted the latest IECC codes to obtain a building permit.
We also provide insulation inspections, and compliance checks for home renovations requiring energy code compliance. Many municipalities now require the HERS rater to sign off on insulation inspections, blower door, and duct blasting to ensure quality work by the contractor and compliance with the relevant energy codes.
