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 by April 1st of each year.

Check Compliance Status Online 

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.

Upcoming Training in July!

The The City of Seattle is offering a free Energy Benchmarking 101 training for participants that are new to the energy benchmarking process or want a refresher. Participants will learn how to benchmark their building's energy performance using the free online tool ENERGY STAR Portfolio Manager to support compliance with the City of Seattle's annual benchmarking and reporting requirement. Participants will also learn about the benchmarking process and local utility services available to auto-upload energy consumption data from Seattle City Light, Puget Sound Energy and Enwave. Participants are encouraged to bring data from their own building to the session. A data collection sheet will be emailed to you prior to the workshop. Sample building data will be available for participants who do not bring their own data.

Benchmarking Analysis Summary Report for 2014-2016 Data

The Office of Sustainability and Environment released a summary report that highlights key building energy and emissions metrics for buildings that benchmark their buildings. The report shows that benchmarked buildings have reduced emissions and saved energy from 2014 to 2016, but that the City's building boom means more savings are needed to meet our ambitious climate goals.

Updated 1-100 ENERGY STAR Scores

The U.S. EPA updated performance metrics in Portfolio Manager in August 2018. Refreshing the ENERGY STAR scale and other related performance metrics is part of EPA's procedure to keep pace with current U.S. building performance. The August 2018 update reflects market performance per the latest U.S. Energy Information Administration (EIA) Commercial Buildings Energy Consumption Survey (CBECS) survey.  ENERGY STAR scores, on average, decreased as most building types in the United States over the last ten plus years have become more energy efficient.
