How has Orosi High School's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Orosi High School, covering report years 2022–2024. Its ENERGY STAR score went from 90 in 2022 to 99 in 2024 (+9 points). Site EUI moved from 49.7 kBtu/ft² (2022) to 25.6 kBtu/ft² (2024), a 48% decrease. Reported emissions went from 183 tCO₂e to 123 tCO₂e over the same span (down 32%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Orosi High School's 25.6 kBtu/ft² across 109,649 sq ft works out to about 2.8 billion Btu (823 MWh-equivalent) in 2024. The disclosure also reports 354,219 kWh of electricity and 10,239 therms of natural gas for the year.
Which law requires Orosi High School to report its energy use?
