More on HERS Ratings
What is HERS?
The Home Energy Rating System (HERS) Index is the industry standard by which a home's energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home's energy performance.
What does a HERS rating say about a house?
The HERS Index measures a home's energy efficiency and there are a lot of great reasons to have a home energy rating performed on your house.
It can tell you so much about the home you live in, like how efficiently it’s operating and where you can make modifications for greater energy savings. When you're selling your home, a low HERS Index Score can command a higher resale price. And when you’re buying a home you can anticipate the costs of energy bills and efficiency upgrades.
How does the HERS Index work?
A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home.
The U.S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index while a standard new home is awarded a rating of 100.
A home with a HERS Index Score of 70 is 30% more energy efficient than a standard new home
A home with a HERS Index Score of 130 is 30% less energy efficient than a standard new home
