Seattle Academy Campus

How does Seattle Academy Campus compare with other K-12 school buildings in Seattle?

The latest disclosures cover 153 K-12 school buildings in Seattle, out of 3,871 buildings citywide. Seattle Academy Campus's ENERGY STAR score of 17 compares with an average of 71 across the 152 that report a score; it scores higher than 4% of them and lower than 95%. Its site EUI of 67.4 kBtu/ft² is about 76% above the average of 38.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 1.4 kgCO₂e/ft² is about 30% above the group average of 1.1 kgCO₂e/ft².

At 164,074 sq ft, it is about twice the average floor area of 79,329 sq ft for those buildings. It was built in 2018, 48 years later than the group's average year built (1970). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

How has Seattle Academy Campus's energy performance changed over time?

BuildingCensus holds 7 Seattle disclosures for Seattle Academy Campus, covering report years 2019–2025. Its ENERGY STAR score went from 43 in 2019 to 17 in 2025 (-26 points); its best year on file was 2020, at 55. Site EUI moved from 56.8 kBtu/ft² (2019) to 67.4 kBtu/ft² (2025), an 19% increase. Reported emissions went from 259 tCO₂e to 235 tCO₂e over the same span (down 9%).

What does an ENERGY STAR score of 17 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 17 means the building performs better than about 17% of its national peers. BuildingCensus bands the score into report-card grades; 17 falls in band D — lowest band (1–54). It sits 58 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 Academy Campus's 67.4 kBtu/ft² across 164,074 sq ft works out to about 11.1 billion Btu (3,241 MWh-equivalent) in 2025. Its source EUI of 146.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,096,845 kWh of electricity and 38,979 therms of natural gas for the year.

Which law requires Seattle Academy Campus to report its energy use?

Seattle Academy Campus 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:50652:2025). 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.
