Its site EUI of 93.5 kBtu/ft² is about 22% above the average of 76.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.5 kgCO₂e/ft² is about 17% above the group average of 4.7 kgCO₂e/ft².
At 70,479 sq ft, it is about 62% below the average floor area of 184,912 sq ft for those buildings. It was built in 1948, 34 years earlier than the group's average year built (1982). Across all 24 jurisdictions BuildingCensus covers, the 178 courthouse buildings average an ENERGY STAR score of 62 and a site EUI of 76.2 kBtu/ft².
What does an ENERGY STAR score of 47 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 47 means the building performs better than about 47% of its national peers. BuildingCensus bands the score into report-card grades; 47 falls in band D — lowest band (1–54). It sits 28 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. 321 Tuolumne's 93.5 kBtu/ft² across 70,479 sq ft works out to about 6.6 billion Btu (1,931 MWh-equivalent) in 2024. The disclosure also reports 811,532 kWh of electricity and 38,709 therms of natural gas for the year.
Which law requires 321 Tuolumne to report its energy use?
321 Tuolumne 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:58264092:2024).
