Herrera Elementary

How does Herrera Elementary 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. Herrera Elementary's ENERGY STAR score of 82 compares with an average of 74 across the 2,016 that report a score; it scores higher than 52% of them and lower than 46%. Its site EUI of 19.5 kBtu/ft² is about 44% 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 1.3 kgCO₂e/ft² is about 37% below the group average of 2.0 kgCO₂e/ft².

At 61,245 sq ft, it is about half of the average floor area of 129,123 sq ft for those buildings. It was built in 1935, 41 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 Herrera Elementary's energy performance changed over time?

BuildingCensus holds 4 California disclosures for Herrera Elementary, covering report years 2021–2024. Its ENERGY STAR score went from 77 in 2021 to 82 in 2024 (+5 points); its best year on file was 2023, at 85. Site EUI moved from 24.9 kBtu/ft² (2021) to 19.5 kBtu/ft² (2024), a 22% decrease. Reported emissions went from 96 tCO₂e to 77 tCO₂e over the same span (down 19%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. Herrera Elementary's 19.5 kBtu/ft² across 61,245 sq ft works out to about 1.2 billion Btu (350 MWh-equivalent) in 2024. The disclosure also reports 292,173 kWh of electricity and 2,091 therms of natural gas for the year.

Which law requires Herrera Elementary to report its energy use?

Herrera 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:23395119:2024). 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.
