How does Mini Warehouse/Warehouse compare with other self-storage facility buildings in Seattle?
The latest disclosures cover 48 self-storage facility buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 17.8 kBtu/ft² is about 14% above the average of 15.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 37% below the group average of 0.3 kgCO₂e/ft².
At 48,179 sq ft, it is about half of the average floor area of 88,206 sq ft for those buildings. It was built in 2006, 30 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 Mini Warehouse/Warehouse's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Mini Warehouse/Warehouse, covering report years 2015–2025. Site EUI moved from 14.4 kBtu/ft² (2015) to 17.8 kBtu/ft² (2025), an 24% increase. Reported emissions went from 10 tCO₂e to 9 tCO₂e over the same span (down 7%).
What does a site EUI of 17.8 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. Mini Warehouse/Warehouse's 17.8 kBtu/ft² across 48,179 sq ft works out to about 0.9 billion Btu (251 MWh-equivalent) in 2025. Its source EUI of 46.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 222,664 kWh of electricity and 980 therms of natural gas for the year.
Which law requires Mini Warehouse/Warehouse to report its energy use?
Mini Warehouse/Warehouse 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:24070:2025). 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.
