How has Fillmore Marketplace Apartments's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Fillmore Marketplace Apartments, covering report years 2018–2025. Its ENERGY STAR score was 100 in both 2022 and 2025. Site EUI moved from 19.9 kBtu/ft² (2021) to 19.0 kBtu/ft² (2025), a 5% decrease. Reported emissions went from 143 tCO₂e to 134 tCO₂e over the same span (down 6%).
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. Fillmore Marketplace Apartments's 19.0 kBtu/ft² across 129,606 sq ft works out to about 2.5 billion Btu (722 MWh-equivalent) in 2025. Its source EUI of 29.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 210,759 kWh of electricity and 17,475 therms of natural gas for the year.
