Its site EUI of 50.0 kBtu/ft² is about 11% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.0 kgCO₂e/ft² is about 17% below the group average of 3.6 kgCO₂e/ft².
At 562,370 sq ft, it is about 270% above the average floor area of 151,937 sq ft for those buildings. It was built in 1969, 16 years earlier than the group's average year built (1985).

How has One California Street's energy performance changed over time?
BuildingCensus holds 5 California disclosures for One California Street, covering report years 2018–2022. Its ENERGY STAR score went from 88 in 2018 to 89 in 2022 (+1 points); its best year on file was 2020, at 93. Site EUI moved from 55.3 kBtu/ft² (2018) to 50.0 kBtu/ft² (2022), a 10% decrease. Reported emissions went from 1,967 tCO₂e to 1,711 tCO₂e over the same span (down 13%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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 California, 65% 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. One California Street's 50.0 kBtu/ft² across 562,370 sq ft works out to about 28.1 billion Btu (8,241 MWh-equivalent) in 2022. The disclosure also reports 3,975,020 kWh of electricity and 147,159 therms of natural gas for the year.
