Its site EUI of 21.4 kBtu/ft² is about 30% below the average of 30.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.3 kgCO₂e/ft² is about 70% below the group average of 0.9 kgCO₂e/ft².
At 99,931 sq ft, it is about 70% above the average floor area of 58,727 sq ft for those buildings. It was built in 1963, 3 years later than the group's average year built (1960). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².
How has Spear Building's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Spear Building, covering report years 2015–2025. Site EUI moved from 39.1 kBtu/ft² (2015) to 21.4 kBtu/ft² (2025), a 45% decrease. Reported emissions went from 93 tCO₂e to 27 tCO₂e over the same span (down 71%).
What does a site EUI of 21.4 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. Spear Building's 21.4 kBtu/ft² across 99,931 sq ft works out to about 2.1 billion Btu (627 MWh-equivalent) in 2025. Its source EUI of 54.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 536,181 kWh of electricity and 3,068 therms of natural gas for the year.
Which law requires Spear Building to report its energy use?
Spear Building 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:24108:2025). 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.
