Its site EUI of 17.1 kBtu/ft² is about half of the average of 34.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.1 kgCO₂e/ft² is about half of the group average of 2.0 kgCO₂e/ft².
At 59,455 sq ft, it is about half of the average floor area of 129,123 sq ft for those buildings. Its 1974 construction date is close to the group's average year built (1976). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
How has San Joaquin Elementary's energy performance changed over time?
BuildingCensus holds 3 California disclosures for San Joaquin Elementary, covering report years 2022–2024. Its ENERGY STAR score went from 91 in 2022 to 86 in 2024 (-5 points); its best year on file was 2022, at 91. Site EUI moved from 14.8 kBtu/ft² (2022) to 17.1 kBtu/ft² (2024), an 16% increase. Reported emissions went from 69 tCO₂e to 64 tCO₂e over the same span (down 6%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. San Joaquin Elementary's 17.1 kBtu/ft² across 59,455 sq ft works out to about 1 billion Btu (298 MWh-equivalent) in 2024. The disclosure also reports 283,496 kWh of electricity for the year.
Which law requires San Joaquin Elementary to report its energy use?
San Joaquin Elementary 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:27495906:2024).
