HERs Report

What it is, and why your Home Should have one

What is a HERs report?

When you’re searching for your next home, you’ll probably encounter a HERS score more than once. At least, you should, if your search includes homes built or renovated after 2006.

HERS stands for Home Energy Rating System. It’s the industry standard by which a home’s energy efficiency is measured and is the nationally recognized system for both inspecting and calculating that home’s energy performance.

Launched in 2006 by the Residential Energy Services Network, or RESNET, HERS scores are meant to be applied to newly built homes and older homes that have been completely renovated since 2006. A RESNET rater will perform an inspection and assessment of the home before calculating the score. The better the score, the more energy (and cost!) efficient that home is.

What is Inspected?

The RESNET raters test every Paul Allen Home and come prepared with an array of equipment to measure and test different areas for energy efficiency. No stone goes unturned. The RESNET rater will thoroughly inspect:


  • All exterior walls, including those below and above grade
  • Floors over unconditioned spaces, such as garages, cellars or basements
  • The roof and all ceilings
  • Infrequently used spaces, such as attics, foundations and crawlspaces
  • Installations that require seals, including windows, doors, vents and ductwork
  • All parts of the HVAC system, including thermostats
  • The water heating system, both tank and tankless
  • Insulation within the walls and ceilings

How to read a HERs report?

A HERS report might seem confusing at first glance, but the easiest way to determine whether a score is good or not is remembering “the lower the better.” Essentially, the lower the rating, the better your score, and the better the home is at using energy efficiently.

The average rating for new homes is 100, and the average rating for lived-in homes is 130. Scores at or around those average ratings indicate that the home was built to code. Higher-than-average scores indicate that the home could use a few upgrades or repairs, while lower-than-average scores indicate the home was built or renovated with high energy efficiency in mind.

Will you ever see a home with a HERS score of 0? In theory, these homes conserve as much energy as they use. While a score of 0 might be the ultimate goal, it’s rare and far from typical. Overall, aiming for any score below the average is a great place to start.

At Paul Allen Green Homes, we build all of our homes with a low HERS score in mind. Not only is energy efficiency good for the environment, but it’s good for your pockets, as well.
