First Church Seattle's ENERGY STAR score of 29 compares with an average of 50 across the 52 that report a score; it scores higher than 19% of them and lower than 77%. Its site EUI of 37.9 kBtu/ft² is roughly in line with the average of 38.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.3 kgCO₂e/ft² is about 11% below the group average of 1.4 kgCO₂e/ft².

At 23,241 sq ft, it is about 29% below the average floor area of 32,782 sq ft for those buildings. It was built in 2009, 61 years later than the group's average year built (1948). Across all 24 jurisdictions BuildingCensus covers, the 1,035 worship facility buildings average an ENERGY STAR score of 50 and a site EUI of 47.8 kBtu/ft².

How has First Church Seattle's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for First Church Seattle, covering report years 2015–2025. Its ENERGY STAR score went from 60 in 2015 to 29 in 2025 (-31 points); its best year on file was 2017, at 100. Site EUI moved from 33.5 kBtu/ft² (2015) to 37.9 kBtu/ft² (2025), an 13% increase. Reported emissions went from 20 tCO₂e to 29 tCO₂e over the same span (up 43%).

What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 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. First Church Seattle's 37.9 kBtu/ft² across 23,241 sq ft works out to about 0.9 billion Btu (258 MWh-equivalent) in 2025. Its source EUI of 66.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 103,317 kWh of electricity and 5,272 therms of natural gas for the year.

Which law requires First Church Seattle to report its energy use?

First Church 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. The record shown here is the report-year 2025 disclosure (source record seattle:21424:2025). 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.
