Reported emissions went from 360 tCO₂e to 143 tCO₂e over the same span (down 60%).

What does an ENERGY STAR score of 14 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 14 means the building performs better than about 14% of its national peers. BuildingCensus bands the score into report-card grades; 14 falls in band D — lowest band (1–54). It sits 61 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. Plymouth Congregational Church's 87.1 kBtu/ft² across 75,058 sq ft works out to about 6.5 billion Btu (1,916 MWh-equivalent) in 2025. Its source EUI of 130.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 265,245 kWh of electricity and 26,255 therms of natural gas for the year.

Which law requires Plymouth Congregational Church to report its energy use?

Plymouth Congregational Church 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:21313:2025). 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.
