What does a site EUI of 96.4 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. Washington Athletic Club's 96.4 kBtu/ft² across 305,548 sq ft works out to about 29.5 billion Btu (8,632 MWh-equivalent) in 2025. Its source EUI of 174.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,368,998 kWh of electricity and 25,344 therms of natural gas for the year.
Which law requires Washington Athletic Club to report its energy use?
Washington Athletic Club 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:401:2025). 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.
