How does Cubberley K-8 compare with other K-12 school buildings in California?

The latest disclosures cover 2,128 K-12 school buildings in California, out of 40,029 buildings citywide. Cubberley K-8's ENERGY STAR score of 54 compares with an average of 74 across the 2,016 that report a score; it scores higher than 19% of them and lower than 81%. Its site EUI of 27.2 kBtu/ft² is about 21% below 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 1.8 kgCO₂e/ft² is about 12% below the group average of 2.0 kgCO₂e/ft².

At 76,128 sq ft, it is about 41% below the average floor area of 129,123 sq ft for those buildings. It was built in 1951, 25 years earlier than 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 Cubberley K-8's energy performance changed over time?

BuildingCensus holds 4 California disclosures for Cubberley K-8, covering report years 2021–2024. Its ENERGY STAR score went from 59 in 2021 to 54 in 2024 (-5 points); its best year on file was 2022, at 61. Site EUI moved from 29.0 kBtu/ft² (2021) to 27.2 kBtu/ft² (2024), a 6% decrease. Reported emissions went from 142 tCO₂e to 135 tCO₂e over the same span (down 5%).

What does an ENERGY STAR score of 54 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 54 means the building performs better than about 54% of its national peers. BuildingCensus bands the score into report-card grades; 54 falls in band D — lowest band (1–54). It sits 21 points below 75, the threshold for ENERGY STAR certification. 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. Cubberley K-8's 27.2 kBtu/ft² across 76,128 sq ft works out to about 2.1 billion Btu (607 MWh-equivalent) in 2024. The disclosure also reports 524,820 kWh of electricity and 3,002 therms of natural gas for the year.

Which law requires Cubberley K-8 to report its energy use?

Cubberley K-8 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:23395094:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
