What does a site EUI of 97.8 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. Womens University Club's 97.8 kBtu/ft² across 39,320 sq ft works out to about 3.8 billion Btu (1,127 MWh-equivalent) in 2025. Its source EUI of 148.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 250,364 kWh of electricity and 8,573 therms of natural gas for the year.
Which law requires Womens University Club to report its energy use?
Womens University 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:20398:2025). 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.
