How has Monte Vista Middle School's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Monte Vista Middle School, covering report years 2023–2024. Its ENERGY STAR score went from 98 in 2023 to 96 in 2024 (-2 points); its best year on file was 2023, at 98. Site EUI moved from 15.7 kBtu/ft² (2023) to 19.6 kBtu/ft² (2024), an 25% increase. Reported emissions went from 112 tCO₂e to 119 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Monte Vista Middle School's 19.6 kBtu/ft² across 94,610 sq ft works out to about 1.9 billion Btu (543 MWh-equivalent) in 2024. The disclosure also reports 351,803 kWh of electricity and 7,446 therms of natural gas for the year.
