Compliance context
Seattle Energy Benchmarking Ordinance (SMC 22.920)
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.

How does Holy Names Academy 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. Holy Names Academy's ENERGY STAR score of 96 compares with an average of 71 across the 152 that report a score; it scores higher than 95% of them and lower than 3%. Its site EUI of 38.4 kBtu/ft² is roughly in line with the average of 38.3 kBtu/ft². Its emissions intensity of 1.3 kgCO₂e/ft² is about 15% above the group average of 1.1 kgCO₂e/ft².
At 168,239 sq ft, it is about twice the average floor area of 79,329 sq ft for those buildings. It was built in 1908, 62 years earlier 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 Holy Names Academy's energy performance changed over time?
BuildingCensus holds 6 Seattle disclosures for Holy Names Academy, covering report years 2020–2025. Its ENERGY STAR score went from 79 in 2020 to 96 in 2025 (+17 points); its best year on file was 2024, at 97. Site EUI moved from 44.0 kBtu/ft² (2020) to 38.4 kBtu/ft² (2025), a 13% decrease. Reported emissions went from 232 tCO₂e to 204 tCO₂e over the same span (down 12%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Holy Names Academy's 38.4 kBtu/ft² across 168,239 sq ft works out to about 6.5 billion Btu (1,893 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 738,476 kWh of electricity and 36,748 therms of natural gas for the year.
Which law requires Holy Names Academy to report its energy use?
Holy Names Academy 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:120:2025). 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.
