Denny/ Sealth Campus (Sps-District)'s ENERGY STAR score of 86 compares with an average of 71 across the 152 that report a score; it scores higher than 70% of them and lower than 27%. Its site EUI of 31.2 kBtu/ft² is about 19% below 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 0.8 kgCO₂e/ft² is about 30% below the group average of 1.1 kgCO₂e/ft².

At 367,884 sq ft, it is about 364% above the average floor area of 79,329 sq ft for those buildings. It was built in 2010, 40 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 Denny/ Sealth Campus (Sps-District)'s energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Denny/ Sealth Campus (Sps-District), covering report years 2015–2025. Its ENERGY STAR score went from 97 in 2015 to 86 in 2025 (-11 points); its best year on file was 2015, at 97. Site EUI moved from 33.8 kBtu/ft² (2015) to 31.2 kBtu/ft² (2025), a 8% decrease. Reported emissions went from 273 tCO₂e to 285 tCO₂e over the same span (up 4%).

What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Denny/ Sealth Campus (Sps-District)'s 31.2 kBtu/ft² across 367,884 sq ft works out to about 11.5 billion Btu (3,364 MWh-equivalent) in 2025. Its source EUI of 64.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,969,177 kWh of electricity and 49,280 therms of natural gas for the year.

Which law requires Denny/ Sealth Campus (Sps-District) to report its energy use?

Denny/ Sealth Campus (Sps-District) 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:225:2025). 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.
