Its ENERGY STAR score went from 3 in 2012 to 100 in 2025 (+97 points); its best year on file was 2023, at 100. Site EUI moved from 25.1 kBtu/ft² (2012) to 0.9 kBtu/ft² (2025), a 96% decrease. Reported emissions went from 45 tCO₂e to 1 tCO₂e over the same span (down 97%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). 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 San Francisco, 73% 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. Fifth Church of Christ, Scientist's 0.9 kBtu/ft² across 26,904 sq ft works out to about 0 billion Btu (7 MWh-equivalent) in 2025. Its source EUI of 1.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,445 kWh of electricity and 135 therms of natural gas for the year.
Which law requires Fifth Church of Christ, Scientist to report its energy use?
Fifth Church of Christ, Scientist reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:0317/007:2025).
