How has One Market Plaza's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for One Market Plaza, covering report years 2011–2025. Its ENERGY STAR score went from 79 in 2011 to 80 in 2025 (+1 points); its best year on file was 2015, at 91. Site EUI moved from 82.7 kBtu/ft² (2011) to 43.4 kBtu/ft² (2025), a 48% decrease. Reported emissions went from 11,760 tCO₂e to 4,406 tCO₂e over the same span (down 63%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). 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 Market Plaza's 43.4 kBtu/ft² across 1,870,178 sq ft works out to about 81.2 billion Btu (23,787 MWh-equivalent) in 2025. Its source EUI of 89.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 13,570,822 kWh of electricity and 331,200 therms of natural gas for the year.
Which law requires One Market Plaza to report its energy use?
One Market Plaza 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:3713/007:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
