How has 850 POWELL ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 850 POWELL ST, covering report years 2018–2025. Its ENERGY STAR score was 100 in both 2022 and 2025. Site EUI moved from 35.3 kBtu/ft² (2019) to 36.0 kBtu/ft² (2025), an 2% increase. Reported emissions went from 212 tCO₂e to 230 tCO₂e over the same span (up 9%).
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. 850 POWELL ST's 36.0 kBtu/ft² across 130,109 sq ft works out to about 4.7 billion Btu (1,373 MWh-equivalent) in 2025. Its source EUI of 50.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 250,829 kWh of electricity and 34,119 therms of natural gas for the year.
Which law requires 850 POWELL ST to report its energy use?
850 POWELL 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:0243/059:2025).
