Energy Benchmarking Reports Due July 1, 2020

Seattle has again extended the Annual Benchmarking Deadline from April 1st to July 1st this year to allow building owners and managers additional time to complete the benchmarking process. Please note that if enrolled in Seattle City Light's automated data exchange, December 2019 data will be uploaded to your Portfolio Manager account on March 3rd.  The Seattle Energy Benchmarking Compliance Portal will be available in Mid-March to start checking compliance status for 2019 reporting.

Seattle's Energy Benchmarking Ordinance directs the City to annually share building-specific data with the public beginning with 2015 data. Building data is now available online for 2015, 2016, 2017, and 2018
