351 Turk

How does 351 Turk compare with other multifamily housing buildings in California?

The latest disclosures cover 10,630 multifamily housing buildings in California, out of 40,029 buildings citywide. 351 Turk's ENERGY STAR score of 96 compares with an average of 82 across the 9,612 that report a score; it scores higher than 60% of them and lower than 37%. Its site EUI of 55.1 kBtu/ft² is about 60% above the average of 34.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 3.2 kgCO₂e/ft² is about 52% above the group average of 2.1 kgCO₂e/ft².

At 89,630 sq ft, it is about 41% below the average floor area of 150,919 sq ft for those buildings. It was built in 1928, 60 years earlier than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has 351 Turk's energy performance changed over time?

BuildingCensus holds 6 California disclosures for 351 Turk, covering report years 2019–2024. Its ENERGY STAR score went from 99 in 2019 to 96 in 2024 (-3 points); its best year on file was 2020, at 100. Site EUI moved from 42.5 kBtu/ft² (2019) to 55.1 kBtu/ft² (2024), an 30% increase. Reported emissions went from 233 tCO₂e to 287 tCO₂e over the same span (up 23%).

What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 California, 65% 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. 351 Turk's 55.1 kBtu/ft² across 89,630 sq ft works out to about 4.9 billion Btu (1,447 MWh-equivalent) in 2024. The disclosure also reports 523,743 kWh of electricity and 31,615 therms of natural gas for the year.

Which law requires 351 Turk to report its energy use?

351 Turk reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:10173371:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
