How does Piedmont High School 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. Piedmont High School's ENERGY STAR score of 98 compares with an average of 74 across the 2,016 that report a score; it scores higher than 87% of them and lower than 11%. Its site EUI of 15.9 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 142,900 sq ft, it is about 11% above 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.
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 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. Piedmont High School's 15.9 kBtu/ft² across 142,900 sq ft works out to about 2.3 billion Btu (666 MWh-equivalent) in 2024. The disclosure also reports 665,562 kWh of electricity for the year.
Which law requires Piedmont High School to report its energy use?
Piedmont High School 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:57187795:2024). 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.
