What does an ENERGY STAR score of 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 500 Montgomery Street's 31.4 kBtu/ft² across 17,795 sq ft works out to about 0.6 billion Btu (164 MWh-equivalent) in 2025. Its source EUI of 56.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 70,795 kWh of electricity and 3,174 therms of natural gas for the year.
Which law requires 500 Montgomery Street to report its energy use?
500 Montgomery 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:0228/013:2025).
