How has Durfee School's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Durfee School, covering report years 2022–2024. Its ENERGY STAR score went from 48 in 2023 to 65 in 2024 (+17 points). Site EUI moved from 41.2 kBtu/ft² (2022) to 42.4 kBtu/ft² (2024), an 3% increase. Reported emissions went from 266 tCO₂e to 264 tCO₂e over the same span (down 1%).
What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 points below 75, the threshold for ENERGY STAR certification. 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. Durfee School's 42.4 kBtu/ft² across 97,117 sq ft works out to about 4.1 billion Btu (1,207 MWh-equivalent) in 2024. The disclosure also reports 993,741 kWh of electricity and 7,286 therms of natural gas for the year.
Which law requires Durfee School to report its energy use?
Durfee 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 2024 disclosure (source record california:27564936:2024).
