How does Stuart Mesa 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. Stuart Mesa School's ENERGY STAR score of 76 compares with an average of 74 across the 2,016 that report a score; it scores higher than 43% of them and lower than 56%. Its site EUI of 28.8 kBtu/ft² is about 17% 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 1.9 kgCO₂e/ft² is roughly in line with the group average of 2.0 kgCO₂e/ft².
At 52,459 sq ft, it is about 59% below the average floor area of 129,123 sq ft for those buildings. It was built in 1994, 18 years later 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.
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. Stuart Mesa School's 28.8 kBtu/ft² across 52,459 sq ft works out to about 1.5 billion Btu (443 MWh-equivalent) in 2024. The disclosure also reports 374,015 kWh of electricity and 2,351 therms of natural gas for the year.
Which law requires Stuart Mesa School to report its energy use?
Stuart Mesa 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:38380892:2024).
