How does Calabasas 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. Calabasas High School's ENERGY STAR score of 58 compares with an average of 74 across the 2,016 that report a score; it scores higher than 22% of them and lower than 77%. Its site EUI of 70.3 kBtu/ft² is about twice the average of 34.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 3.7 kgCO₂e/ft² is about 85% above the group average of 2.0 kgCO₂e/ft².
At 160,000 sq ft, it is about 24% 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 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. Calabasas High School's 70.3 kBtu/ft² across 160,000 sq ft works out to about 11.2 billion Btu (3,296 MWh-equivalent) in 2022. The disclosure also reports 1,321,078 kWh of electricity and 53,757 therms of natural gas for the year.
Which law requires Calabasas High School to report its energy use?
Calabasas 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 2022 disclosure (source record california:3965783:2022). 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.
