The Home Energy Score is a measurement of the energy efficiency of a home based on an onsite evaluation of the physical characteristics of the house. this evaluation includes the building's envelope (foundation, windows, insulation, etc.), its heating & Cooling systems (including water heating), and any renewable energy systems, such as solar PV. The Score is based on a 1-to-10 scale, with a 1 being the least efficient and 10 being the most efficient.
A Home Energy Score is not a measurement of the household's actual energy usage, which is influenced by occupant behavior (i.e. appliances, lighting, & thermostat settings).
Do I need a home energy score?
The policy only applies to home sellers that are listing or advertising a home for sale publicly in any manner starting on or after January 1, 2018 and within Portland’s jurisdictional city boundary.
Will i need to make improvements based on my score?
Nope. Not unless you feel like improving your score. The report will list potential improvements that can help increase your home's score, comfort, and overall energy efficiency
