Seattle Pottery's ENERGY STAR score of 41 compares with an average of 58 across the 117 that report a score; it scores higher than 27% of them and lower than 71%. Its site EUI of 32.6 kBtu/ft² is roughly in line with the average of 30.5 kBtu/ft². Its emissions intensity of 0.8 kgCO₂e/ft² is about 10% below the group average of 0.9 kgCO₂e/ft².

At 65,288 sq ft, it is about 11% above the average floor area of 58,727 sq ft for those buildings. It was built in 1917, 43 years earlier 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 Seattle Pottery's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Seattle Pottery, covering report years 2015–2025. Its ENERGY STAR score went from 51 in 2021 to 41 in 2025 (-10 points); its best year on file was 2021, at 51. Site EUI moved from 9.0 kBtu/ft² (2015) to 32.6 kBtu/ft² (2025), an 262% increase. Reported emissions went from 4 tCO₂e to 53 tCO₂e over the same span (up 1372%).

What does an ENERGY STAR score of 41 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 41 means the building performs better than about 41% of its national peers. BuildingCensus bands the score into report-card grades; 41 falls in band D — lowest band (1–54). It sits 34 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. Seattle Pottery's 32.6 kBtu/ft² across 65,288 sq ft works out to about 2.1 billion Btu (624 MWh-equivalent) in 2025. Its source EUI of 67.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 360,116 kWh of electricity and 8,987 therms of natural gas for the year.

Which law requires Seattle Pottery to report its energy use?

Seattle Pottery 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:812:2025). 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.
