How does Pacific Plumbing compare with other non-refrigerated warehouse buildings in Seattle?
The latest disclosures cover 164 non-refrigerated warehouse buildings in Seattle, out of 3,871 buildings citywide. Pacific Plumbing's ENERGY STAR score of 59 compares with an average of 58 across the 117 that report a score; it scores higher than 44% of them and lower than 54%. Its site EUI of 28.6 kBtu/ft² is roughly in line with 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 0.7 kgCO₂e/ft² is about 21% below the group average of 0.9 kgCO₂e/ft².
At 26,150 sq ft, it is about 55% below the average floor area of 58,727 sq ft for those buildings. Its 1962 construction date is close to 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 Pacific Plumbing's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Pacific Plumbing, covering report years 2015–2025. Its ENERGY STAR score went from 6 in 2016 to 59 in 2025 (+53 points); its best year on file was 2024, at 59. Site EUI moved from 46.2 kBtu/ft² (2016) to 28.6 kBtu/ft² (2025), a 38% decrease. Reported emissions went from 16 tCO₂e to 19 tCO₂e over the same span (up 15%).
What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 points below 75, the threshold for ENERGY STAR certification. 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. Pacific Plumbing's 28.6 kBtu/ft² across 26,150 sq ft works out to about 0.7 billion Btu (219 MWh-equivalent) in 2025. Its source EUI of 58.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 126,802 kWh of electricity and 3,142 therms of natural gas for the year.
Which law requires Pacific Plumbing to report its energy use?
Pacific Plumbing 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:21792:2025). 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.
