Energy Benchmarking

The benchmarking reporting deadline has been extended to July 1, 2019 for submitting 2018 data. 

Seattle's Energy Benchmarking Program (SMC 22.920) requires owners of non-residential and multifamily buildings (20,000 sf or larger) to track energy performance and annually report to the City of Seattle.

Warning Letters Issued

Starting July 2, 2019, warning letters will be sent to all non-compliant buildings noting owners have until October 1, 2019 to submit or correct benchmarking reports to avoid enforcement action with assessed fines. Warning letters are mailed to the owner of record and their registered agent. 

Check Compliance Status

Once you have completed the Annual Update Checklist, you can check your building's compliance status at the new Seattle Energy Benchmarking Compliance Portal.

Verification will be required for buildings with possible errors. The City of Seattle is now identifying annual benchmarking reports with possible errors and requiring further review. This applies to buildings with either extremely low or high energy use (outliers), buildings that could be missing a fuel or meters, and buildings with potential errors in reporting square footage.
