Its ENERGY STAR score went from 97 in 2011 to 98 in 2025 (+1 points); its best year on file was 2023, at 99. Site EUI moved from 29.4 kBtu/ft² (2011) to 16.8 kBtu/ft² (2025), a 43% decrease. Reported emissions went from 992 tCO₂e to 374 tCO₂e over the same span (down 62%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 123 MISSION STREET's 16.8 kBtu/ft² across 418,566 sq ft works out to about 7 billion Btu (2,061 MWh-equivalent) in 2025. Its source EUI of 33.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,090,169 kWh of electricity and 30,311 therms of natural gas for the year.
Which law requires 123 MISSION STREET to report its energy use?
123 MISSION STREET 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:3717/022:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
