Its site EUI of 52.4 kBtu/ft² is about 24% below the average of 69.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.1 kgCO₂e/ft² is about half of the group average of 2.1 kgCO₂e/ft².
At 25,406 sq ft, it is about half of the average floor area of 52,695 sq ft for those buildings. It was built in 1960, 13 years earlier than the group's average year built (1973). Across all 24 jurisdictions BuildingCensus covers, the 399 fitness center/health club/gym buildings average an ENERGY STAR score of 89 and a site EUI of 112.4 kBtu/ft².
How has Health Club's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Health Club, covering report years 2015–2025. Site EUI moved from 89.6 kBtu/ft² (2015) to 52.4 kBtu/ft² (2025), a 42% decrease. Reported emissions went from 37 tCO₂e to 28 tCO₂e over the same span (down 23%).
What does a site EUI of 52.4 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. Health Club's 52.4 kBtu/ft² across 25,406 sq ft works out to about 1.3 billion Btu (390 MWh-equivalent) in 2025. Its source EUI of 115.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 258,208 kWh of electricity and 4,512 therms of natural gas for the year.
Which law requires Health Club to report its energy use?
Health 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:25124:2025). 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.
