Portland City Council unanimously passed the Home Energy Score Ordinance in 2016, requiring the disclosure of a Home Energy Score and Report when a home is publicly advertised for sale in Portland, and Home Energy Score requirements went into effect January 1, 2018. Since then, Portlanders have recorded over 50,000 Home Energy Scores.
A Home Energy Report provides a simple indicator of energy efficiency. For low scoring homes, it also provides a road map of improvements that can improve comfort, save energy and cut costs. The Home Energy Score rates the home on a 10-point scale, where 10 represents a highly efficient home; provides an estimate of annual energy costs assuming average occupant behavior; and includes customized recommendations to homeowners and potential home buyers for how to make the home more energy efficient.
The Home Energy Score and Report provides transparency, insight and data about residential energy performance and carbon emissions. For homeowners, this report is your roadmap to a more comfortable and affordable living space. For homebuyers, it can help you compare the full costs of owning and operating each home you consider on an apples-to-apples basis.
The Home Energy Score program provides a solid foundation to scale residential energy upgrades. These upgrades are a critical next step in improving the health, comfort, affordability and safety of Portland homes, while reducing carbon emissions necessary to meet our collective climate action goals.
All homes publicly advertised for sale within the city of Portland should include a Home Energy Score, and it should appear in all listings, public advertisements, and during on-site showings and open houses. The Home Energy Score is valid for eight years, provided that no changes to mechanical systems, energy efficiency or square footage in the home have occurred.
As we mark 50,000 reports, this year also marks the expiration for those Home Energy Scores recorded in 2018. This means many homes that were scored then will need a new Home Energy Score and Report when they are listed for sale. If you plan to sell your home, follow these simple steps to ensure your home has a valid score.
