The Home Energy Score is a uniform rating system for predicting home energy use based on the “envelope”, energy systems, and square footage of your home. The one-hour assessment is conducted by a Home Energy Score Certified Assessor who collects data about the home and then uses software to estimate annual house energy use.
There are a variety of factors that a Home Energy Score Certified Assessor looks at within and without your home. The assessment takes about an hour and, in Portland, is a requirement before the sale of the home. The assessment takes into consideration heating, cooling, and water heating systems, fuel types, occupant behavior, weather, and the home envelope.

Average Portland Home Energy Scores
A home energy score (HES) is rated on a scale of 1 to 10 with 1 being a home with high energy use and 10 being a home with low energy use. Once the score is calculated recommendations are made that give details on the types of home improvements that can lower energy costs.
Portland was one of the first cities in the U.S. to require home energy score assessments before a home is listed. On average, homes in Portland rank about 4.7 HES.
One of the benefits of getting a HES before a homeowner sells is that it offers an opportunity for the seller to improve the property before the sale, which can increase the home’s market value.
Top Recommendations for Low-Scoring Homes
The most common recommended improvements for homes in Portland include:
- sealing gaps and cracks that allow air leakage into the home
- sealing ducts to reduce airflow leakage
- upgrading HVAC to energy-efficient heat pumps
- insulating exterior walls, attic, basement, and crawl spaces
