Its site EUI of 23.4 kBtu/ft² is about 59% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.4 kgCO₂e/ft² is about 61% below the group average of 3.6 kgCO₂e/ft².
At 105,307 sq ft, it is about 31% below the average floor area of 151,937 sq ft for those buildings. It was built in 2007, 22 years later than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. 810 Vaca Valley's 23.4 kBtu/ft² across 105,307 sq ft works out to about 2.5 billion Btu (722 MWh-equivalent) in 2021. The disclosure also reports 664,271 kWh of electricity and 1,515 therms of natural gas for the year.
Which law requires 810 Vaca Valley to report its energy use?
810 Vaca Valley 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 2021 disclosure (source record california:6274285:2021).
