How has 850 MONTGOMERY ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 850 MONTGOMERY ST, covering report years 2011–2025. Its ENERGY STAR score went from 58 in 2013 to 57 in 2025 (-1 points); its best year on file was 2022, at 77. Site EUI moved from 55.4 kBtu/ft² (2013) to 59.9 kBtu/ft² (2025), an 8% increase. Reported emissions went from 104 tCO₂e to 82 tCO₂e over the same span (down 21%).
What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. 850 MONTGOMERY ST's 59.9 kBtu/ft² across 25,000 sq ft works out to about 1.5 billion Btu (439 MWh-equivalent) in 2025. Its source EUI of 108.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 190,299 kWh of electricity and 8,489 therms of natural gas for the year.
Which law requires 850 MONTGOMERY ST to report its energy use?
850 MONTGOMERY 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:0175/033:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
