How has 3185 WASHINGTON ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 3185 WASHINGTON ST, covering report years 2011–2025. Its ENERGY STAR score went from 33 in 2013 to 70 in 2025 (+37 points); its best year on file was 2020, at 92. Site EUI moved from 37.4 kBtu/ft² (2013) to 39.2 kBtu/ft² (2025), an 5% increase. Reported emissions went from 74 tCO₂e to 27 tCO₂e over the same span (down 64%).
What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. 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. 3185 WASHINGTON ST's 39.2 kBtu/ft² across 12,000 sq ft works out to about 0.5 billion Btu (138 MWh-equivalent) in 2025. Its source EUI of 109.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 137,830 kWh of electricity and 1 therms of natural gas for the year.
Which law requires 3185 WASHINGTON ST to report its energy use?
3185 WASHINGTON 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:0999/026:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
