How has 1621 MARKET ST's energy performance changed over time?
BuildingCensus holds 3 San Francisco disclosures for 1621 MARKET ST, covering report years 2023–2025. Its ENERGY STAR score went from 64 in 2024 to 75 in 2025 (+11 points).

What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). 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. 1621 MARKET ST's 19.8 kBtu/ft² across 31,000 sq ft works out to about 0.6 billion Btu (180 MWh-equivalent) in 2025. Its source EUI of 49.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 150,067 kWh of electricity for the year.
Which law requires 1621 MARKET ST to report its energy use?
1621 MARKET 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.
