Eastlake Middle School's ENERGY STAR score of 78 compares with an average of 74 across the 2,016 that report a score; it scores higher than 45% of them and lower than 53%. Its site EUI of 30.1 kBtu/ft² is about 13% 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 1.3 kgCO₂e/ft² is about 35% below the group average of 2.0 kgCO₂e/ft².
At 123,245 sq ft, it is roughly in line with the average floor area of 129,123 sq ft for those buildings. It was built in 1970, 6 years earlier than the group's average year built (1976).

How has Eastlake Middle School's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Eastlake Middle School, covering report years 2019–2023. Its ENERGY STAR score went from 89 in 2019 to 78 in 2023 (-11 points); its best year on file was 2020, at 100. Site EUI moved from 23.0 kBtu/ft² (2019) to 30.1 kBtu/ft² (2023), an 31% increase. Reported emissions went from 86 tCO₂e to 165 tCO₂e over the same span (up 92%).
What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. Eastlake Middle School's 30.1 kBtu/ft² across 123,245 sq ft works out to about 3.7 billion Btu (1,087 MWh-equivalent) in 2023. The disclosure also reports 491,340 kWh of electricity and 8,685 therms of natural gas for the year.
Which law requires Eastlake Middle School to report its energy use?
Eastlake Middle School 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 2023 disclosure (source record california:9484102:2023).
