The Home Energy Score rates a home’s general energy efficiency on a scale from 1 to 10. The scoring system was developed by the U.S. Department of Energy. Portland, Milwaukie and Hillsboro require home sellers to obtain a Home Energy Score by an Oregon licensed Home Energy Assessor. The score must be disclosed when listing a home publicly for sale. The score is meant to give potential home buyers an estimate of the annual costs to operate a home, and recommendations on how to improve the efficiency.
The assessment required to generate a Home Energy Score is basic. The Home Energy Score only considers the home’s fixed attributes (walls, windows, heating, cooling, and water heating systems), and applies standard assumptions about occupant behavior. This is different than a home energy audit, which is more extensive and includes additional variables. A full energy audit is not required before listing a home for sale in Portland or Milwaukie.
Collecting data for a Home Energy Score takes 30-60 minutes at the home, depending on the size. If there is an attic or a crawl space, access to those areas is required. Many times the access is located in a closet, so some items may need to be moved. After all of the data has been entered into the U.S. Department of Energy’s calculating software, a report and score is generated. A score of 1 indicates that the home needs extensive energy improvements, while a score of 10 indicates that the home has excellent energy performance. A score of 5 represents the average home in the United States.
