At 700,079 sq ft, it is about 552% above the average floor area of 107,408 sq ft for those buildings. It was built in 2000, 59 years later than the group's average year built (1941). Across all 24 jurisdictions BuildingCensus covers, the 2,307 commercial buildings average an ENERGY STAR score of 76 and a site EUI of 51.3 kBtu/ft².
How has 2 Folsom's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 2 Folsom, covering report years 2011–2025. Its ENERGY STAR score went from 83 in 2011 to 70 in 2025 (-13 points); its best year on file was 2012, at 95. Site EUI moved from 58.5 kBtu/ft² (2011) to 48.3 kBtu/ft² (2025), a 17% decrease. Reported emissions went from 2,717 tCO₂e to 1,516 tCO₂e over the same span (down 44%).
What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 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. 2 Folsom's 48.3 kBtu/ft² across 700,079 sq ft works out to about 33.8 billion Btu (9,910 MWh-equivalent) in 2025. Its source EUI of 111.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,663,500 kWh of electricity and 77,505 therms of natural gas for the year.
Which law requires 2 Folsom to report its energy use?
2 Folsom 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:3741/046:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
