SF American ACE Supply's ENERGY STAR score of 82 compares with an average of 78 across the 790 that report a score; it scores higher than 42% of them and lower than 56%. Its site EUI of 7.8 kBtu/ft² is about 84% below the average of 49.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.5 kgCO₂e/ft² is about 83% below the group average of 2.7 kgCO₂e/ft².

At 18,634 sq ft, it is about 83% below the average floor area of 107,408 sq ft for those buildings. It was built in 1948, 7 years later than the group's average year built (1941). Across all 24 jurisdictions BuildingCensus covers, the 2,307 commercial buildings average an ENERGY STAR score of 76 and a site EUI of 51.3 kBtu/ft².

How has SF American ACE Supply's energy performance changed over time?

BuildingCensus holds 4 San Francisco disclosures for SF American ACE Supply, covering report years 2022–2025. Its ENERGY STAR score went from 80 in 2022 to 82 in 2025 (+2 points); its best year on file was 2024, at 82. Site EUI moved from 8.3 kBtu/ft² (2022) to 7.8 kBtu/ft² (2025), a 6% decrease. Reported emissions went from 11 tCO₂e to 8 tCO₂e over the same span (down 21%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 falls in band B — above median (70–84). 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. SF American ACE Supply's 7.8 kBtu/ft² across 18,634 sq ft works out to about 0.1 billion Btu (43 MWh-equivalent) in 2025. Its source EUI of 21.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 42,705 kWh of electricity for the year.

Which law requires SF American ACE Supply to report its energy use?

SF American ACE Supply 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:5590A/009:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
