How has Hilltop Middle School's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Hilltop Middle School, covering report years 2019–2023. Its ENERGY STAR score went from 97 in 2019 to 93 in 2023 (-4 points); its best year on file was 2020, at 100. Site EUI moved from 17.6 kBtu/ft² (2019) to 24.6 kBtu/ft² (2023), an 40% increase. Reported emissions went from 44 tCO₂e to 89 tCO₂e over the same span (up 103%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Hilltop Middle School's 24.6 kBtu/ft² across 89,221 sq ft works out to about 2.2 billion Btu (643 MWh-equivalent) in 2023. The disclosure also reports 214,979 kWh of electricity and 6,955 therms of natural gas for the year.
Which law requires Hilltop Middle School to report its energy use?
