How has Seattle Art Museum's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seattle Art Museum, covering report years 2015–2025. Site EUI moved from 221.1 kBtu/ft² (2015) to 71.9 kBtu/ft² (2025), a 67% decrease. Reported emissions went from 1,906 tCO₂e to 1,277 tCO₂e over the same span (down 33%).
What does a site EUI of 71.9 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Seattle Art Museum's 71.9 kBtu/ft² across 280,230 sq ft works out to about 20.1 billion Btu (5,905 MWh-equivalent) in 2025. Its source EUI of 158.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 7,194,523 kWh of electricity and 6,898 therms of natural gas for the year.
Which law requires Seattle Art Museum to report its energy use?
Seattle Art Museum reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record seattle:525:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
