Hughes Elementary School (Sps-District)'s ENERGY STAR score of 75 compares with an average of 71 across the 152 that report a score; it scores higher than 45% of them and lower than 53%. Its site EUI of 35.5 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 0.9 kgCO₂e/ft² is about 15% below the group average of 1.1 kgCO₂e/ft².
At 44,324 sq ft, it is about 44% below the average floor area of 79,329 sq ft for those buildings. It was built in 1926, 44 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 Hughes Elementary School (Sps-District)'s energy performance changed over time?
BuildingCensus holds 8 Seattle disclosures for Hughes Elementary School (Sps-District), covering report years 2018–2025. Its ENERGY STAR score went from 77 in 2021 to 75 in 2025 (-2 points); its best year on file was 2021, at 77. Site EUI moved from 33.2 kBtu/ft² (2019) to 35.5 kBtu/ft² (2025), an 7% increase. Reported emissions went from 17 tCO₂e to 47 tCO₂e over the same span (up 179%).
What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). 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. Hughes Elementary School (Sps-District)'s 35.5 kBtu/ft² across 44,324 sq ft works out to about 1.6 billion Btu (461 MWh-equivalent) in 2025. Its source EUI of 70.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 280,406 kWh of electricity and 8,439 therms of natural gas for the year.
Which law requires Hughes Elementary School (Sps-District) to report its energy use?
Hughes Elementary School (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:141:2025). 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.
