HERS Ratings

A Home Energy Rating is a requirement for many green building and energy efficient building standards, and is the nation's leading "miles-per-gallon" equivalent for homes.

What is a HERS Rating?

A HERS Rating assigns a home a score on a scale from 0-150, with lower numbers representing less energy consumption (a HERS score of 0 represents a "zero energy home," which produces at least as much energy as it consumes), and higher numbers representing greater energy consumption. A standard new home would receive a score of around 100, and most existing homes fall somewhere between 100 and 150.

What are the Benefits of a HERS Rating?

A HERS Rating is a requirement for many green building and energy efficient building standards across the country, including ENERGY STAR for Homes. A HERS Rating is also a requirement for an Energy Efficient Mortgage (EEM) and/or an Energy Improvement Mortgage (EIM). Further, it can be a great way for builders and realtors to set their homes apart in a crowded real estate market -- a good HERS score is an objective, measured representation of a home's energy efficiency. Much as miles-per-gallon fuel efficiency ratings for automobiles play an increasingly important role in car-buyers' decisions, a Home Energy Rating may soon play an equally important role in the homebuying process for homebuyers across the country.

Keep in mind the Rating is not perfect and the size of the house can skew the results.  You need to compare HERS scores to similar sized homes for a true comparison.  It is not exacly like a miles-per-gallon rating.
