How has Public Market South Garage's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Public Market South Garage, covering report years 2015–2025. Site EUI moved from 84.4 kBtu/ft² (2015) to 87.9 kBtu/ft² (2025), an 4% increase. Reported emissions went from 67 tCO₂e to 85 tCO₂e over the same span (up 26%).
What does a site EUI of 87.9 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. Public Market South Garage's 87.9 kBtu/ft² across 197,395 sq ft works out to about 17.4 billion Btu (5,085 MWh-equivalent) in 2025. Its source EUI of 192.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 734,229 kWh of electricity and 13,301 therms of natural gas for the year.
Which law requires Public Market South Garage to report its energy use?
Public Market South Garage 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:49945:2025). 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.
