TheHome Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s the nationally recognized system for inspecting and calculating a home’s energy performance. A home’s HERS score tell you how that home operates. The lower the number, the more energy efficient the home.

Tests include verification of density of insulation, vapor and air barriers, blower door tests (to check for house leakage), duct system performance testing, and many others. The U.S. Department of Energy has determined that a typical standard new home is awarded a rating of 100 and a one point drop in the HERS score means 1% less use of energy in the home. A lower HERS score can save you BIG in your annual utility costs.

So, when buying a new home, how important is that home's HERS rating to you? Does it influence your decision to buy? Thanks for the feedback!
