Its site EUI of 3.2 kBtu/ft² is about 90% 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 0.0 kgCO₂e/ft² is about 98% below the group average of 0.9 kgCO₂e/ft².
At 170,632 sq ft, it is about 191% above the average floor area of 58,727 sq ft for those buildings. It was built in 1966, 6 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 Puget Sound -Terminal 7 B's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Puget Sound -Terminal 7 B, covering report years 2015–2025. Its ENERGY STAR score went from 97 in 2015 to 95 in 2024 (-2 points); its best year on file was 2015, at 97. Site EUI moved from 3.9 kBtu/ft² (2015) to 3.2 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 4 tCO₂e to 3 tCO₂e over the same span (down 21%).
What does a site EUI of 3.2 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. Puget Sound -Terminal 7 B's 3.2 kBtu/ft² across 170,632 sq ft works out to about 0.5 billion Btu (160 MWh-equivalent) in 2025. Its source EUI of 8.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 157,040 kWh of electricity for the year.
Which law requires Puget Sound -Terminal 7 B to report its energy use?
Puget Sound -Terminal 7 B 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:813:2025). 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.
