B6's ENERGY STAR score of 1 compares with an average of 75 across the 4,912 that report a score; it scores higher than 0% of them and lower than 97%. Its site EUI of 296.8 kBtu/ft² is about 426% 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 19.3 kgCO₂e/ft² is about 437% above the group average of 3.6 kgCO₂e/ft².
At 90,374 sq ft, it is about 41% below the average floor area of 151,937 sq ft for those buildings. It was built in 1990, 5 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.
How has B6's energy performance changed over time?
BuildingCensus holds 7 California disclosures for B6, covering report years 2018–2024. Its ENERGY STAR score went from 4 in 2018 to 1 in 2024 (-3 points); its best year on file was 2018, at 4. Site EUI moved from 137.9 kBtu/ft² (2018) to 296.8 kBtu/ft² (2024), an 115% increase. Reported emissions went from 826 tCO₂e to 1,746 tCO₂e over the same span (up 111%).
What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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. B6's 296.8 kBtu/ft² across 90,374 sq ft works out to about 26.8 billion Btu (7,861 MWh-equivalent) in 2024. The disclosure also reports 7,102,168 kWh of electricity and 25,939 therms of natural gas for the year.
Which law requires B6 to report its energy use?
B6 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:6810654:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
