How does Grass Valley Charter 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. Grass Valley Charter School's ENERGY STAR score of 89 compares with an average of 74 across the 2,016 that report a score; it scores higher than 64% of them and lower than 33%. Its site EUI of 44.1 kBtu/ft² is about 27% above 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 2.4 kgCO₂e/ft² is about 20% above the group average of 2.0 kgCO₂e/ft².
At 52,772 sq ft, it is about 59% below the average floor area of 129,123 sq ft for those buildings. It was built in 1938, 38 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.
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. Grass Valley Charter School's 44.1 kBtu/ft² across 52,772 sq ft works out to about 2.3 billion Btu (682 MWh-equivalent) in 2022. The disclosure also reports 185,960 kWh of electricity and 15,679 therms of natural gas for the year.
Which law requires Grass Valley Charter School to report its energy use?
Grass Valley Charter 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:27577206:2022).
