How does 30955 San Antonio St compare with other non-refrigerated warehouse buildings in California?

The latest disclosures cover 2,867 non-refrigerated warehouse buildings in California, out of 40,029 buildings citywide. 30955 San Antonio St's ENERGY STAR score of 90 compares with an average of 68 across the 2,227 that report a score; it scores higher than 66% of them and lower than 32%. Its site EUI of 8.5 kBtu/ft² is about 61% below the average of 21.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.5 kgCO₂e/ft² is about 65% below the group average of 1.4 kgCO₂e/ft².

At 100,050 sq ft, it is about 42% below the average floor area of 173,929 sq ft for those buildings. It was built in 1973, 15 years earlier than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 30955 San Antonio St's 8.5 kBtu/ft² across 100,050 sq ft works out to about 0.9 billion Btu (249 MWh-equivalent) in 2024. The disclosure also reports 121,547 kWh of electricity and 4,095 therms of natural gas for the year.

Which law requires 30955 San Antonio St to report its energy use?

30955 San Antonio St 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.
