Seattle’s Energy Benchmarking Law (Seattle Municipal Code 22.920) requires owners of non-residential and multifamily buildings (greater than 20,000 square feet) to track energy performance and annually report to the City of Seattle. See the Seattle Energy Benchmarking Fact Sheet for more information.
The City of Seattle annually publishes building energy and emissions performance data from more than 3,600 of Seattle’s largest nonresidential and multifamily buildings representing 375 million square feet at data.seattle.gov and through the Seattle Energy Benchmarking Map to facilitate transparency in the market and spur demand for energy efficiency.
Beginning in 2024, the annual compliance deadline for the prior reporting year (RY) will be June 1st. The City is implementing a new penalty structure for RY2023 and fines for non-compliance will be issued 90 days after the compliance deadline. Not currently in compliance? Review our Benchmarking Instructions page and complete the benchmarking process.
Please be advised that communications from soliciting third-party service providers may contain inaccurate information regarding compliance status, deadlines, and Seattle benchmarking program requirements. Official email communications from the City of Seattle regarding benchmarking compliance will be sent via a seattle.gov email address. Notification letters, warning letters, and Notices of Violation sent through the postal service will prominently feature City of Seattle branding.
