How has Hidden Hills Elementary's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Hidden Hills Elementary, covering report years 2020–2021. Its ENERGY STAR score went from 95 in 2020 to 84 in 2021 (-11 points); its best year on file was 2020, at 95. Site EUI moved from 17.7 kBtu/ft² (2020) to 23.9 kBtu/ft² (2021), an 35% increase. Reported emissions went from 69 tCO₂e to 93 tCO₂e over the same span (up 35%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. Hidden Hills Elementary's 23.9 kBtu/ft² across 67,252 sq ft works out to about 1.6 billion Btu (471 MWh-equivalent) in 2021. The disclosure also reports 335,927 kWh of electricity and 4,497 therms of natural gas for the year.
Which law requires Hidden Hills Elementary to report its energy use?
