Energy Benchmarking

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. Owners must report each calendar year of benchmarking data by June 1st of the following year. 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.

Please note that the appeals window for Reporting Year 2023 violations has now closed. As of 11/4/2024, the Compliance Portal is no longer being updated.
