‘Home Energy Score’ Comes to N.C.

Do you live in a “1” or a “10”? Existing homes in North Carolina can now be assigned a score measuring energy efficiency.

Some building assessment organizations and affiliated contractors across the state are adopting the U.S. Department of Energy’s Home Energy Score (HES) rating system for existing homes. More than 45,000 homes have received a score nationwide.

“For homeowners, it’s a clear and easy way to understand how they can ultimately save money by making their home more energy efficient,” said Ryan Miller, the N.C. Building Performance Association’s founder and executive director. “Likewise, contractors can use this tool as a guide to help homeowners in their renovation decisions and expand their available services. It’s a win-win for everyone involved.”

Through HES, existing homes can receive a score of 1–10, with 10 being very efficient. A score of five is seen as comparable to an average U.S. home. The rating quantifies current energy use and identifies simple ways to reduce utility costs at an average of 15 percent. The HES assessment also provides homeowners with recommendations for energy upgrades and an estimate of how these improvements would reduce utility bills and improve the home’s overall score.

The Western North Carolina Green Building Council is the official provider of HES in the state (through its Green Gauge program) and can provide more information.
