Mission Viejo High's ENERGY STAR score of 80 compares with an average of 74 across the 2,016 that report a score; it scores higher than 48% of them and lower than 50%. Its site EUI of 24.0 kBtu/ft² is about 31% below the average of 34.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.6 kgCO₂e/ft² is about 20% below the group average of 2.0 kgCO₂e/ft².
At 238,220 sq ft, it is about 84% above the average floor area of 129,123 sq ft for those buildings. It was built in 1965, 11 years earlier than 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 Mission Viejo High's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Mission Viejo High, covering report years 2022–2024. Its ENERGY STAR score went from 66 in 2022 to 80 in 2024 (+14 points). Site EUI moved from 25.5 kBtu/ft² (2022) to 24.0 kBtu/ft² (2024), a 6% decrease. Reported emissions went from 464 tCO₂e to 379 tCO₂e over the same span (down 18%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. Mission Viejo High's 24.0 kBtu/ft² across 238,220 sq ft works out to about 5.7 billion Btu (1,676 MWh-equivalent) in 2024. The disclosure also reports 1,674,538 kWh of electricity for the year.
Which law requires Mission Viejo High to report its energy use?
Mission Viejo High reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:27498042:2024).
