How has Seattle University (Main Campus)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seattle University (Main Campus), covering report years 2015–2025. Site EUI moved from 66.9 kBtu/ft² (2015) to 61.7 kBtu/ft² (2025), a 8% decrease. Reported emissions went from 3,153 tCO₂e to 3,213 tCO₂e over the same span (up 2%).
What does a site EUI of 61.7 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 University (Main Campus)'s 61.7 kBtu/ft² across 2,099,379 sq ft works out to about 129.5 billion Btu (37,962 MWh-equivalent) in 2025. Its source EUI of 117.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 15,952,680 kWh of electricity and 574,233 therms of natural gas for the year.
Which law requires Seattle University (Main Campus) to report its energy use?
Seattle University (Main Campus) 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:22062:2025). 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.
