Its site EUI of 8.6 kBtu/ft² is about 83% 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 82% below the group average of 2.7 kgCO₂e/ft².
At 15,500 sq ft, it is about 86% below the average floor area of 107,408 sq ft for those buildings. It was built in 1929, 12 years earlier 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 334 BRANNAN ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 334 BRANNAN ST, covering report years 2011–2025. Its ENERGY STAR score was 100 in both 2013 and 2025. Site EUI moved from 26.2 kBtu/ft² (2013) to 8.6 kBtu/ft² (2025), a 67% decrease. Reported emissions went from 26 tCO₂e to 7 tCO₂e over the same span (down 72%).
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. 334 BRANNAN ST's 8.6 kBtu/ft² across 15,500 sq ft works out to about 0.1 billion Btu (39 MWh-equivalent) in 2025. Its source EUI of 22.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 33,563 kWh of electricity and 143 therms of natural gas for the year.
Which law requires 334 BRANNAN ST to report its energy use?
334 BRANNAN ST 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:3775/101:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
