How has 2 TOWNSEND ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 2 TOWNSEND ST, covering report years 2018–2025. Its ENERGY STAR score was 100 in both 2022 and 2025. Site EUI moved from 9.5 kBtu/ft² (2022) to 9.3 kBtu/ft² (2025), a 2% decrease. Reported emissions went from 253 tCO₂e to 225 tCO₂e over the same span (down 11%).
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. 2 TOWNSEND ST's 9.3 kBtu/ft² across 433,191 sq ft works out to about 4 billion Btu (1,181 MWh-equivalent) in 2025. Its source EUI of 19.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 720,223 kWh of electricity and 15,913 therms of natural gas for the year.
Which law requires 2 TOWNSEND ST to report its energy use?
