How has Bank of Orient's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Bank of Orient, covering report years 2011–2025. Its ENERGY STAR score went from 74 in 2012 to 69 in 2025 (-5 points); its best year on file was 2016, at 89. Site EUI moved from 67.4 kBtu/ft² (2012) to 49.8 kBtu/ft² (2025), a 26% decrease. Reported emissions went from 219 tCO₂e to 145 tCO₂e over the same span (down 34%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 points below 75, the threshold for ENERGY STAR certification. 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. Bank of Orient's 49.8 kBtu/ft² across 53,743 sq ft works out to about 2.7 billion Btu (784 MWh-equivalent) in 2025. Its source EUI of 75.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 206,808 kWh of electricity and 19,713 therms of natural gas for the year.
Which law requires Bank of Orient to report its energy use?
Bank of Orient 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:0260/002:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
