How has 50 California Street's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 50 California Street, covering report years 2011–2025. Its ENERGY STAR score went from 94 in 2011 to 97 in 2025 (+3 points); its best year on file was 2017, at 97. Site EUI moved from 45.7 kBtu/ft² (2011) to 21.1 kBtu/ft² (2025), a 54% decrease. Reported emissions went from 2,968 tCO₂e to 868 tCO₂e over the same span (down 71%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. 50 California Street's 21.1 kBtu/ft² across 785,149 sq ft works out to about 16.6 billion Btu (4,855 MWh-equivalent) in 2025. Its source EUI of 42.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,571,177 kWh of electricity and 68,957 therms of natural gas for the year.
Which law requires 50 California Street to report its energy use?
