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 Saint Nicholas Building 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. Saint Nicholas Building's ENERGY STAR score of 89 compares with an average of 71 across the 152 that report a score; it scores higher than 79% of them and lower than 20%. Its site EUI of 38.0 kBtu/ft² is roughly in line with the average of 38.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.6 kgCO₂e/ft² is about 50% above the group average of 1.1 kgCO₂e/ft².
At 45,960 sq ft, it is about 42% below the average floor area of 79,329 sq ft for those buildings. It was built in 1930, 40 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 Saint Nicholas Building's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Saint Nicholas Building, covering report years 2015–2025. Its ENERGY STAR score went from 58 in 2015 to 89 in 2025 (+31 points). Site EUI moved from 88.7 kBtu/ft² (2015) to 38.0 kBtu/ft² (2025), a 57% decrease. Reported emissions went from 174 tCO₂e to 76 tCO₂e over the same span (down 56%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. Saint Nicholas Building's 38.0 kBtu/ft² across 45,960 sq ft works out to about 1.7 billion Btu (512 MWh-equivalent) in 2025. Its source EUI of 52.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 94,782 kWh of electricity and 14,234 therms of natural gas for the year.
Which law requires Saint Nicholas Building to report its energy use?
Saint Nicholas Building 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:21521:2025). 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.
