Its site EUI of 19.9 kBtu/ft² is about 35% 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 0.1 kgCO₂e/ft² is about 86% below the group average of 0.9 kgCO₂e/ft².
At 166,014 sq ft, it is about 183% above the average floor area of 58,727 sq ft for those buildings. It was built in 1972, 12 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 Prologis Park 15's energy performance changed over time?
BuildingCensus holds 8 Seattle disclosures for Prologis Park 15, covering report years 2018–2025. Its ENERGY STAR score went from 34 in 2018 to 39 in 2021 (+5 points). Site EUI moved from 36.8 kBtu/ft² (2018) to 19.9 kBtu/ft² (2025), a 46% decrease. Reported emissions went from 63 tCO₂e to 19 tCO₂e over the same span (down 70%).
What does a site EUI of 19.9 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. Prologis Park 15's 19.9 kBtu/ft² across 166,014 sq ft works out to about 3.3 billion Btu (968 MWh-equivalent) in 2025. Its source EUI of 55.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 832,022 kWh of electricity and 466 therms of natural gas for the year.
Which law requires Prologis Park 15 to report its energy use?
Prologis Park 15 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:865:2025). 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.
