Its site EUI of 5.7 kBtu/ft² is about 63% below the average of 15.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 67% below the group average of 0.3 kgCO₂e/ft².
At 104,022 sq ft, it is about 18% above the average floor area of 88,206 sq ft for those buildings. It was built in 2019, 43 years later than the group's average year built (1976). Across all 24 jurisdictions BuildingCensus covers, the 3,050 self-storage facility buildings average an ENERGY STAR score of 75 and a site EUI of 9.4 kBtu/ft².
How has West Coast Self-Storage's energy performance changed over time?
BuildingCensus holds 5 Seattle disclosures for West Coast Self-Storage, covering report years 2021–2025. Site EUI moved from 5.3 kBtu/ft² (2021) to 5.7 kBtu/ft² (2025), an 8% increase. Reported emissions went from 2 tCO₂e to 8 tCO₂e over the same span (up 391%).
What does a site EUI of 5.7 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. West Coast Self-Storage's 5.7 kBtu/ft² across 104,022 sq ft works out to about 0.6 billion Btu (174 MWh-equivalent) in 2025. Its source EUI of 12.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 91,889 kWh of electricity and 1,475 therms of natural gas for the year.
Which law requires West Coast Self-Storage to report its energy use?
West Coast Self-Storage 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:23549:2025). 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.
