Its site EUI of 65.6 kBtu/ft² is about 16% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 4.6 kgCO₂e/ft² is about 28% above the group average of 3.6 kgCO₂e/ft².
At 91,068 sq ft, it is about 40% below the average floor area of 151,937 sq ft for those buildings. It was built in 2008, 23 years later than the group's average year built (1985).

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. C&W Symantec Mvcb's 65.6 kBtu/ft² across 91,068 sq ft works out to about 6 billion Btu (1,751 MWh-equivalent) in 2018. The disclosure also reports 1,751,626 kWh of electricity for the year.
Which law requires C&W Symantec Mvcb to report its energy use?
C&W Symantec Mvcb 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 2018 disclosure (source record california:6872944:2018).
