How does 650 CHESTNUT ST compare with other mixed residential buildings in San Francisco?
The latest disclosures cover 610 mixed residential buildings in San Francisco, out of 2,509 buildings citywide. 650 CHESTNUT ST's ENERGY STAR score of 97 compares with an average of 85 across the 340 that report a score; it scores higher than 53% of them and lower than 43%. Its site EUI of 18.9 kBtu/ft² is about half of 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 1.1 kgCO₂e/ft² is about half of the group average of 2.0 kgCO₂e/ft².
At 54,396 sq ft, it is about 67% below the average floor area of 165,572 sq ft for those buildings. It was built in 1995, 29 years later than the group's average year built (1967).
How has 650 CHESTNUT ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 650 CHESTNUT ST, covering report years 2018–2025. Its ENERGY STAR score went from 96 in 2022 to 97 in 2025 (+1 points); its best year on file was 2024, at 97. Site EUI moved from 21.3 kBtu/ft² (2019) to 18.9 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 67 tCO₂e to 57 tCO₂e over the same span (down 15%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. 650 CHESTNUT ST's 18.9 kBtu/ft² across 54,396 sq ft works out to about 1 billion Btu (301 MWh-equivalent) in 2025. Its source EUI of 41.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 195,085 kWh of electricity and 3,603 therms of natural gas for the year.
Which law requires 650 CHESTNUT ST to report its energy use?
650 CHESTNUT 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:0051/081:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
