The Oregon Dept. of Energy(ODOE) established a new Home Energy Score initiative in early 2019 to offer a standardized approach to home energy scoring in Portland. The official website can be viewed here. Home Energy Scores in Portland are meant to help homeowners and homebuyers identify improvements that can be made in order to make a difference in energy savings, comfort, health, and durability of a property. It is my opinion that the system is flawed, but it is one that we must adhere to. In my experience, buyers are not choosing to buy homes or not based on these reports however in new homes, they certainly do speak to the standards of the build. In older homes, it is a bit skewed.
An older home, even if modernized, is generally going to perform poorly on the HES test. This does not mean the home is poorly designed or inefficient. Old homes are simply old homes! In addition, larger homes will also normally perform poorly simply because of their size. Nonetheless, the HES is a required test in the listing and selling process in Multnomah County.
A Home Energy Score (HES) report is comprised of three parts: the Score itself, facts about the home and its estimated energy use, and recommendations to improve a home’s score.
This report is an energy efficiency score based on the home’s building envelope, heating, cooling, and hot water systems. A total energy use evaluation, as well as operating estimates by fuel type, assuming standard operating conditions. Recommendations for cost-effective improvements and associated annual cost savings estimates are included. These can be found in a section called; “Score with Improvements” which reflects the home’s expected score if the cost-effective improvements are made.
Home Energy Scores are only required in Portland/Multnomah County detached and attached properties. The seller does not have to provide this to a buyer but they are subject to fines if they do not.
