1600 15TH ST

How does 1600 15TH ST compare with other multifamily buildings in San Francisco?

The latest disclosures cover 192 multifamily buildings in San Francisco, out of 2,509 buildings citywide. 1600 15TH ST's ENERGY STAR score of 97 compares with an average of 86 across the 129 that report a score; it scores higher than 58% of them and lower than 36%. Its site EUI of 30.3 kBtu/ft² is about 13% below the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.7 kgCO₂e/ft² is about 13% below the group average of 1.9 kgCO₂e/ft².

At 261,974 sq ft, it is about 37% above the average floor area of 191,699 sq ft for those buildings. It was built in 2013, 27 years later than the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 238 multifamily buildings average an ENERGY STAR score of 86 and a site EUI of 34.8 kBtu/ft².

How has 1600 15TH ST's energy performance changed over time?

BuildingCensus holds 8 San Francisco disclosures for 1600 15TH ST, covering report years 2018–2025. Its ENERGY STAR score went from 93 in 2018 to 97 in 2025 (+4 points); its best year on file was 2024, at 99. Site EUI moved from 33.2 kBtu/ft² (2018) to 30.3 kBtu/ft² (2025), a 9% decrease. Reported emissions went from 456 tCO₂e to 376 tCO₂e over the same span (down 17%).

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. 1600 15TH ST's 30.3 kBtu/ft² across 261,974 sq ft works out to about 7.9 billion Btu (2,326 MWh-equivalent) in 2025. Its source EUI of 55.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 892,613 kWh of electricity and 38,008 therms of natural gas for the year.

Which law requires 1600 15TH ST to report its energy use?

1600 15TH 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:3547/054:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
