Its ENERGY STAR score went from 84 in 2015 to 57 in 2025 (-27 points); its best year on file was 2016, at 86. Site EUI moved from 44.4 kBtu/ft² (2015) to 45.6 kBtu/ft² (2025), an 3% increase. Reported emissions went from 41 tCO₂e to 44 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. Lutheran Church/Tilden School's 45.6 kBtu/ft² across 21,364 sq ft works out to about 1 billion Btu (286 MWh-equivalent) in 2025. Its source EUI of 58.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 38,914 kWh of electricity and 8,411 therms of natural gas for the year.
Which law requires Lutheran Church/Tilden School to report its energy use?
Lutheran Church/Tilden School 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:19787:2025). 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.
