How has 555 Montgomery St's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 555 Montgomery St, covering report years 2018–2024. Its ENERGY STAR score went from 84 in 2018 to 90 in 2024 (+6 points); its best year on file was 2021, at 94. Site EUI moved from 36.0 kBtu/ft² (2018) to 28.3 kBtu/ft² (2024), a 21% decrease. Reported emissions went from 552 tCO₂e to 466 tCO₂e over the same span (down 15%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 555 Montgomery St's 28.3 kBtu/ft² across 261,583 sq ft works out to about 7.4 billion Btu (2,170 MWh-equivalent) in 2024. The disclosure also reports 1,408,223 kWh of electricity and 27,773 therms of natural gas for the year.
