Bixby Knolls Apts's ENERGY STAR score of 89 compares with an average of 82 across the 9,612 that report a score; it scores higher than 45% of them and lower than 53%. Its site EUI of 34.2 kBtu/ft² is roughly in line with the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.0 kgCO₂e/ft² is roughly in line with the group average of 2.1 kgCO₂e/ft².

At 168,736 sq ft, it is about 12% above the average floor area of 150,919 sq ft for those buildings. Its 1987 construction date is close to the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

Reported emissions went from 415 tCO₂e to 335 tCO₂e over the same span (down 19%).

What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. Bixby Knolls Apts's 34.2 kBtu/ft² across 168,736 sq ft works out to about 5.8 billion Btu (1,691 MWh-equivalent) in 2024. The disclosure also reports 689,674 kWh of electricity and 33,686 therms of natural gas for the year.

Which law requires Bixby Knolls Apts to report its energy use?

Bixby Knolls Apts 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:6310149:2024). 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.
