33 TURK ST

How does 33 TURK 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. 33 TURK ST's ENERGY STAR score of 100 compares with an average of 85 across the 340 that report a score; it scores higher than 69% of them. Its site EUI of 33.4 kBtu/ft² is roughly in line with 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 1.9 kgCO₂e/ft² is roughly in line with the group average of 2.0 kgCO₂e/ft².

At 403,485 sq ft, it is about 144% above the average floor area of 165,572 sq ft for those buildings. It was built in 2022, 56 years later than the group's average year built (1967).

How has 33 TURK ST's energy performance changed over time?

BuildingCensus holds 3 San Francisco disclosures for 33 TURK ST, covering report years 2023–2025. Its ENERGY STAR score went from 49 in 2023 to 100 in 2025 (+51 points). Site EUI moved from 73.8 kBtu/ft² (2023) to 33.4 kBtu/ft² (2025), a 55% decrease. Reported emissions went from 655 tCO₂e to 736 tCO₂e over the same span (up 12%).

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. 33 TURK ST's 33.4 kBtu/ft² across 403,485 sq ft works out to about 13.5 billion Btu (3,950 MWh-equivalent) in 2025. Its source EUI of 72.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,299,863 kWh of electricity and 26,695 therms of natural gas for the year.

Which law requires 33 TURK ST to report its energy use?

33 TURK 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:0342/045:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
