Energy Benchmarking
Seattle's Energy Benchmarking Law (Seattle Municipal Code 22.920) requires owners of non-residential and multifamily buildings (20,000 square feet or larger) 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 3600 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.
Check Compliance for Benchmarking Reports
Note: Warning letters have been issued to building owners who have not reported 2022 benchmarking data to the City of Seattle. Owners have until January 1, 2024, to bring their building into compliance to avoid penalties.
