How has Public Storage (Store 8501)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Public Storage (Store 8501), covering report years 2015–2025. Its ENERGY STAR score went from 85 in 2015 to 82 in 2017 (-3 points); its best year on file was 2015, at 85. Site EUI moved from 7.8 kBtu/ft² (2015) to 7.0 kBtu/ft² (2025), a 10% decrease. Reported emissions went from 6 tCO₂e to 5 tCO₂e over the same span (down 21%).
What does a site EUI of 7.0 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 Storage (Store 8501)'s 7.0 kBtu/ft² across 132,828 sq ft works out to about 0.9 billion Btu (272 MWh-equivalent) in 2025. Its source EUI of 19.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 243,009 kWh of electricity for the year.
Which law requires Public Storage (Store 8501) to report its energy use?
Public Storage (Store 8501) 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:845:2025). 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.
