How has Hidden Hills Elementary's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Hidden Hills Elementary, covering report years 2022–2023. Its ENERGY STAR score was 100 in both 2022 and 2023. Site EUI moved from 26.5 kBtu/ft² (2022) to 26.1 kBtu/ft² (2023), a 2% decrease. Reported emissions went from 25 tCO₂e to 29 tCO₂e over the same span (up 14%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Hidden Hills Elementary's 26.1 kBtu/ft² across 67,252 sq ft works out to about 1.8 billion Btu (514 MWh-equivalent) in 2023. The disclosure also reports -7,470 kWh of electricity and 5,786 therms of natural gas for the year.
