Puget Sound Freight Lines-Terminal 7a's ENERGY STAR score of 86 compares with an average of 58 across the 117 that report a score; it scores higher than 86% of them and lower than 11%. Its site EUI of 5.2 kBtu/ft² is about 83% 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 88% below the group average of 0.9 kgCO₂e/ft².
At 152,365 sq ft, it is about 159% above the average floor area of 58,727 sq ft for those buildings. It was built in 1965, 5 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 Freight Lines-Terminal 7a's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Puget Sound Freight Lines-Terminal 7a, covering report years 2015–2025. Its ENERGY STAR score was 86 in both 2015 and 2025. Site EUI moved from 7.9 kBtu/ft² (2015) to 5.2 kBtu/ft² (2025), a 34% decrease. Reported emissions went from 19 tCO₂e to 18 tCO₂e over the same span (down 5%).
What does an ENERGY STAR score of 86 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Seattle, 69% of scored buildings are at 75 or above.
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 Freight Lines-Terminal 7a's 5.2 kBtu/ft² across 152,365 sq ft works out to about 0.8 billion Btu (232 MWh-equivalent) in 2025. Its source EUI of 11.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 157,877 kWh of electricity and 2,814 therms of natural gas for the year.
Which law requires Puget Sound Freight Lines-Terminal 7a to report its energy use?
Puget Sound Freight Lines-Terminal 7a 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:857:2025). 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.
