How has 365 MAIN ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 365 MAIN ST, covering report years 2011–2025. Its ENERGY STAR score went from 100 in 2014 to 15 in 2025 (-85 points); its best year on file was 2014, at 100. Site EUI moved from 951.1 kBtu/ft² (2016) to 431.9 kBtu/ft² (2025), a 55% decrease. Reported emissions went from 16,371 tCO₂e to 5,613 tCO₂e over the same span (down 66%).
What does an ENERGY STAR score of 15 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 15 means the building performs better than about 15% of its national peers. BuildingCensus bands the score into report-card grades; 15 falls in band D — lowest band (1–54). It sits 60 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. 365 MAIN ST's 431.9 kBtu/ft² across 240,291 sq ft works out to about 103.8 billion Btu (30,415 MWh-equivalent) in 2025. Its source EUI of 1205.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 28,572,600 kWh of electricity for the year.
Which law requires 365 MAIN ST to report its energy use?
365 MAIN ST 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:3745/008:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
