City Light provides energy consumption data for non-residential and multifamily buildings. Data for your building can be set up for automated transfer to the EPA ENERGY STAR(R) Portfolio Manager to support customer compliance with state and local energy benchmarking requirements. Consumption reports are also available on a limited basis to support energy conservation efforts.

Washington State requires public, non-residential and multifamily buildings to meet minimum state energy code. Track your building's energy consumption by requesting whole building energy usage data from City Light. This information can be used for your compliance with state law, Seattle Municipal Code 22.920 - Energy Use Benchmarking, and managing energy consumption.

Washington State Clean Buildings Energy Performance Standard

The Washington State legislature enacted the Clean Buildings law on May 7, 2019. It originally required owners of non-residential buildings over 50,000 square feet to benchmark energy consumption, meet an energy performance target, establish an energy management plan, and implement an Operations & Maintenance program. The law was updated with the Clean Buildings Expansion Bill in 2022 to include a second tier of non-residential buildings over 20,000 square feet and multifamily buildings over 50,000 square feet. Compliance with the standard begins in 2026 and is phased in based on building size.
