Potrero Launch

How does Potrero Launch 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. Potrero Launch's ENERGY STAR score of 98 compares with an average of 85 across the 340 that report a score; it scores higher than 57% of them and lower than 38%. Its site EUI of 26.3 kBtu/ft² is about 27% below 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 1.5 kgCO₂e/ft² is about 27% below the group average of 2.0 kgCO₂e/ft².

At 211,905 sq ft, it is about 28% above the average floor area of 165,572 sq ft for those buildings. It was built in 2013, 47 years later than the group's average year built (1967).

How has Potrero Launch's energy performance changed over time?

BuildingCensus holds 8 San Francisco disclosures for Potrero Launch, covering report years 2018–2025. Its ENERGY STAR score went from 100 in 2018 to 98 in 2025 (-2 points); its best year on file was 2018, at 100. Site EUI moved from 32.1 kBtu/ft² (2018) to 26.3 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 287 tCO₂e to 285 tCO₂e over the same span (down 1%).

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Potrero Launch's 26.3 kBtu/ft² across 211,905 sq ft works out to about 5.6 billion Btu (1,633 MWh-equivalent) in 2025. Its source EUI of 54.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 880,496 kWh of electricity and 21,395 therms of natural gas for the year.

Which law requires Potrero Launch to report its energy use?

Potrero Launch 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:4058/010:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
