How has Seattle World School At T.t. Minor (Sps-District)'s energy performance changed over time?

BuildingCensus holds 9 Seattle disclosures for Seattle World School At T.t. Minor (Sps-District), covering report years 2017–2025. Its ENERGY STAR score went from 90 in 2017 to 78 in 2025 (-12 points); its best year on file was 2020, at 94. Site EUI moved from 36.5 kBtu/ft² (2017) to 44.3 kBtu/ft² (2025), an 21% increase. Reported emissions went from 51 tCO₂e to 63 tCO₂e over the same span (up 24%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. Seattle World School At T.t. Minor (Sps-District)'s 44.3 kBtu/ft² across 57,048 sq ft works out to about 2.5 billion Btu (741 MWh-equivalent) in 2025. Its source EUI of 90.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 429,489 kWh of electricity and 10,934 therms of natural gas for the year.

Which law requires Seattle World School At T.t. Minor (Sps-District) to report its energy use?

Seattle World School At T.t.
