Its site EUI of 37.4 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 1.4 kgCO₂e/ft² is roughly in line with the group average of 1.4 kgCO₂e/ft².

At 26,033 sq ft, it is about 21% below the average floor area of 32,782 sq ft for those buildings. Its 1949 construction date is close to 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 Latter Day Saints Church's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Latter Day Saints Church, covering report years 2015–2025. Its ENERGY STAR score went from 88 in 2015 to 37 in 2025 (-51 points); its best year on file was 2015, at 88. Site EUI moved from 34.0 kBtu/ft² (2015) to 37.4 kBtu/ft² (2025), an 10% increase. Reported emissions went from 40 tCO₂e to 42 tCO₂e over the same span (up 6%).

What does an ENERGY STAR score of 37 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 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 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. Latter Day Saints Church's 37.4 kBtu/ft² across 26,033 sq ft works out to about 1 billion Btu (285 MWh-equivalent) in 2025. Its source EUI of 56.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 88,062 kWh of electricity and 8,221 therms of natural gas for the year.

Which law requires Latter Day Saints Church to report its energy use?

Latter Day Saints 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:21239:2025). 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.
