Energy Benchmarking

EPA's ENERGY STAR Portfolio Manager is offline due to the government shutdown. Please inquire with our help desk as some benchmarking steps can be accomplished outside of Portfolio Manager. At this time, we are maintaining the April 1st reporting deadline. 

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.

New Benchmarking Analysis Summary Report for 2014-2016 Data

The Office of Sustainability and Environment released a new 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 in August 2018

The U.S. EPA is updating 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 will be reflective of market performance per the latest U.S. Energy Information Administration (EIA) Commercial Buildings Energy Consumption Survey (CBECS) survey.  When the performance metrics are updated, ENERGY STAR scores, on average, are expected to go down as most building types in the United States over the last ten plus years have become more energy efficient.

If you currently have a building with an ENERGY STAR score of 75 or higher, you may still apply for ENERGY STAR certification now-EPA will continue to assess applications on the pre-updated scores if submitted by July 26, 2018.
