City of Portland Requires Home Energy Scores

2.22.18 by the Green Hammer Team
  • Hale Remodel

Starting January 1, 2018, the city of Portland started requiring sellers of single-family homes to disclose a Home Energy Report and Score at the time of listing. This is great news for Green Hammer clients who have invested in energy efficiency measures for their homes. The requirement could mean that sellers will be more likely to recoup the costs of energy-efficiency measures. For buyers, a Home Energy Score (HES) helps them understand the true costs of operating a home, compare energy costs between homes, understand the impact of potential home improvements before investing in the home, and potentially make them eligible for specific energy improvement loans. 

The HES is an energy rating that scores the house on a scale from 1 to 10, and also provides the consumer with a yearly estimated cost of energy and a set of recommended upgrades. A 10 is the most energy efficient score on the HES scale, while a home with a score of 1 is least energy efficient. Earth Advantage contracts with the City of Portland as the Quality Assurance Provider and train Home Energy Assessors.

If you have an Earth Advantage certified home, you do not automatically fulfill the city's new requirement. For homeowners who fail to get a Home Energy Score prior to listing their house, the ordinance allows for fines of up to $500. If you're a former Green Hammer client and have any questions, feel free to reach out to us. 

We are fully supportive of the city's requirement and believe it will help increase demand for the high-performance homes that we're committed to building. 

Between January 1, 2018 – February 12, 2018, Earth Advantage reported:

  • There were 873 City of Portland Home Energy Scores created.
  • The average Portland home received a score of 4.4
  • The average Portland home could achieve a score of 7.1 if all cost-effective improvements were made.
  • The average Portland homeowner could save $305 per year through greater energy efficiency.
