How has Islamic School Of Seattle's energy performance changed over time?
BuildingCensus holds 6 Seattle disclosures for Islamic School Of Seattle, covering report years 2020–2025. Its ENERGY STAR score was 100 in both 2020 and 2025. Site EUI moved from 3.3 kBtu/ft² (2020) to 2.1 kBtu/ft² (2025), a 36% decrease. Reported emissions went from 1 tCO₂e to 0 tCO₂e over the same span (down 40%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Islamic School Of Seattle's 2.1 kBtu/ft² across 24,152 sq ft works out to about 0.1 billion Btu (15 MWh-equivalent) in 2025. Its source EUI of 5.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 14,915 kWh of electricity for the year.
Which law requires Islamic School Of Seattle to report its energy use?
Islamic School Of Seattle 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.
