Its site EUI of 4.2 kBtu/ft² is about 88% below the average of 36.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 88% below the group average of 2.0 kgCO₂e/ft².
At 167,500 sq ft, it is roughly in line with the average floor area of 165,572 sq ft for those buildings. It was built in 2021, 55 years later than the group's average year built (1967).
How has 2050-2070 FOLSOM ST's energy performance changed over time?
BuildingCensus holds 3 San Francisco disclosures for 2050-2070 FOLSOM ST, covering report years 2023–2025. Its ENERGY STAR score was 100 in both 2024 and 2025. Site EUI moved from 8.6 kBtu/ft² (2024) to 4.2 kBtu/ft² (2025), a 51% decrease. Reported emissions went from 82 tCO₂e to 41 tCO₂e over the same span (down 51%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 2050-2070 FOLSOM ST's 4.2 kBtu/ft² across 167,500 sq ft works out to about 0.7 billion Btu (206 MWh-equivalent) in 2025. Its source EUI of 11.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 208,190 kWh of electricity for the year.
Which law requires 2050-2070 FOLSOM ST to report its energy use?
2050-2070 FOLSOM 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:3571/031:2025).
