The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. 100 Potrero's ENERGY STAR score of 92 compares with an average of 75 across the 4,912 that report a score; it scores higher than 69% of them and lower than 28%. Its site EUI of 31.1 kBtu/ft² is about 45% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.0 kgCO₂e/ft² is about 44% below the group average of 3.6 kgCO₂e/ft².
At 70,000 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 1910, 75 years earlier than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 100 Potrero's energy performance changed over time?
BuildingCensus holds 4 California disclosures for 100 Potrero, covering report years 2019–2022. Its ENERGY STAR score went from 88 in 2021 to 92 in 2022 (+4 points). Site EUI moved from 3.4 kBtu/ft² (2019) to 31.1 kBtu/ft² (2022), an 815% increase. Reported emissions went from 16 tCO₂e to 138 tCO₂e over the same span (up 768%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. 100 Potrero's 31.1 kBtu/ft² across 70,000 sq ft works out to about 2.2 billion Btu (638 MWh-equivalent) in 2022. The disclosure also reports 367,954 kWh of electricity and 9,774 therms of natural gas for the year.
