How has 1 Montgomery St's energy performance changed over time?
BuildingCensus holds 4 California disclosures for 1 Montgomery St, covering report years 2018–2021. Its ENERGY STAR score went from 85 in 2018 to 100 in 2021 (+15 points).

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 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. 1 Montgomery St's 9.0 kBtu/ft² across 75,880 sq ft works out to about 0.7 billion Btu (200 MWh-equivalent) in 2021. The disclosure also reports 199,803 kWh of electricity for the year.
