The latest disclosures cover 610 mixed residential buildings in San Francisco, out of 2,509 buildings citywide. 2133 STOCKTON ST's ENERGY STAR score of 91 compares with an average of 85 across the 340 that report a score; it scores higher than 37% of them and lower than 59%. Its site EUI of 40.2 kBtu/ft² is about 12% above the average of 36.0 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.2 kgCO₂e/ft² is roughly in line with the group average of 2.0 kgCO₂e/ft².

At 76,576 sq ft, it is about half of the average floor area of 165,572 sq ft for those buildings. Its 1964 construction date is close to the group's average year built (1967).

How has 2133 STOCKTON ST's energy performance changed over time?

BuildingCensus holds 8 San Francisco disclosures for 2133 STOCKTON ST, covering report years 2018–2025. Its ENERGY STAR score was 91 in both 2022 and 2025. Site EUI moved from 24.8 kBtu/ft² (2020) to 40.2 kBtu/ft² (2025), an 62% increase. Reported emissions went from 116 tCO₂e to 166 tCO₂e over the same span (up 43%).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 2133 STOCKTON ST's 40.2 kBtu/ft² across 76,576 sq ft works out to about 3.1 billion Btu (902 MWh-equivalent) in 2025. Its source EUI of 56.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 179,560 kWh of electricity and 24,630 therms of natural gas for the year.

Which law requires 2133 STOCKTON ST to report its energy use?

2133 STOCKTON 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:0040/001:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
