One Montgomery Center Tower's ENERGY STAR score of 86 compares with an average of 78 across the 790 that report a score; it scores higher than 50% of them and lower than 46%. Its site EUI of 28.7 kBtu/ft² is about 42% below the average of 49.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.7 kgCO₂e/ft² is about 37% below the group average of 2.7 kgCO₂e/ft².
At 1,096,276 sq ft, it is about 921% above the average floor area of 107,408 sq ft for those buildings. It was built in 1982, 41 years later than the group's average year built (1941).

How has One Montgomery Center Tower's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for One Montgomery Center Tower, covering report years 2011–2025. Its ENERGY STAR score went from 91 in 2011 to 86 in 2025 (-5 points); its best year on file was 2017, at 93. Site EUI moved from 40.3 kBtu/ft² (2011) to 28.7 kBtu/ft² (2025), a 29% decrease. Reported emissions went from 3,793 tCO₂e to 1,803 tCO₂e over the same span (down 52%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. One Montgomery Center Tower's 28.7 kBtu/ft² across 1,096,276 sq ft works out to about 31.5 billion Btu (9,221 MWh-equivalent) in 2025. Its source EUI of 69.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,734,067 kWh of electricity and 4,500 therms of natural gas for the year.
Which law requires One Montgomery Center Tower to report its energy use?
One Montgomery Center Tower reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:0292/004:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
