Its ENERGY STAR score went from 90 in 2018 to 98 in 2022 (+8 points); its best year on file was 2020, at 98. Site EUI moved from 47.4 kBtu/ft² (2018) to 27.6 kBtu/ft² (2022), a 42% decrease. Reported emissions went from 1,288 tCO₂e to 729 tCO₂e over the same span (down 43%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 600 California Street's 27.6 kBtu/ft² across 398,740 sq ft works out to about 11 billion Btu (3,225 MWh-equivalent) in 2022. The disclosure also reports 2,627,152 kWh of electricity and 21,539 therms of natural gas for the year.
