Its site EUI of 57.8 kBtu/ft² is about 51% 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 2.2 kgCO₂e/ft² is about twice the group average of 1.1 kgCO₂e/ft².
At 41,526 sq ft, it is about half of the average floor area of 79,329 sq ft for those buildings. Its 1970 construction date is close to 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 Sanislo Elementary School (Sps-District)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Sanislo Elementary School (Sps-District), covering report years 2015–2025. Its ENERGY STAR score went from 73 in 2015 to 46 in 2025 (-27 points); its best year on file was 2016, at 79. Site EUI moved from 49.1 kBtu/ft² (2015) to 57.8 kBtu/ft² (2025), an 18% increase. Reported emissions went from 67 tCO₂e to 93 tCO₂e over the same span (up 39%).
What does an ENERGY STAR score of 46 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 46 means the building performs better than about 46% of its national peers. BuildingCensus bands the score into report-card grades; 46 falls in band D — lowest band (1–54). It sits 29 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. Sanislo Elementary School (Sps-District)'s 57.8 kBtu/ft² across 41,526 sq ft works out to about 2.4 billion Btu (703 MWh-equivalent) in 2025. Its source EUI of 91.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 221,849 kWh of electricity and 17,092 therms of natural gas for the year.
Which law requires Sanislo Elementary School (Sps-District) to report its energy use?
Sanislo 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:24164:2025). 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.
