What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. San Francisco-Canterbury's 75.2 kBtu/ft² across 92,968 sq ft works out to about 7 billion Btu (2,049 MWh-equivalent) in 2025. Its source EUI of 120.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 639,127 kWh of electricity and 48,137 therms of natural gas for the year.

Which law requires San Francisco-Canterbury to report its energy use?

San Francisco-Canterbury 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:0282/022:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
