Its site EUI of 43.7 kBtu/ft² is about 26% 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 2.6 kgCO₂e/ft² is about 31% above the group average of 2.0 kgCO₂e/ft².
At 129,775 sq ft, it is roughly in line with the average floor area of 129,123 sq ft for those buildings. Its 1976 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.
How has Standley Middle's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Standley Middle, covering report years 2022–2024. Its ENERGY STAR score went from 32 in 2022 to 27 in 2024 (-5 points); its best year on file was 2022, at 32. Site EUI moved from 39.4 kBtu/ft² (2022) to 43.7 kBtu/ft² (2024), an 11% increase. Reported emissions went from 327 tCO₂e to 342 tCO₂e over the same span (up 5%).
What does an ENERGY STAR score of 27 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 27 means the building performs better than about 27% of its national peers. BuildingCensus bands the score into report-card grades; 27 falls in band D — lowest band (1–54). It sits 48 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. Standley Middle's 43.7 kBtu/ft² across 129,775 sq ft works out to about 5.7 billion Btu (1,662 MWh-equivalent) in 2024. The disclosure also reports 791,070 kWh of electricity and 30,615 therms of natural gas for the year.
Which law requires Standley Middle to report its energy use?
