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. Benchmarking data for the 2020 calendar year is due by July 1st, 2021.

The City of Seattle annually publishes building energy performance data from more than 3500 of Seattle's largest commercial and residential buildings representing 375 million square feet at data.seattle.gov and through a data visualization site to facilitate transparency in the market and spur demand for energy efficiency.
