The Bonaventure's ENERGY STAR score of 58 compares with an average of 82 across the 9,612 that report a score; it scores higher than 13% of them and lower than 86%. Its site EUI of 26.9 kBtu/ft² is about 22% below 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 1.6 kgCO₂e/ft² is about 21% below the group average of 2.1 kgCO₂e/ft².

At 100,930 sq ft, it is about 33% below the average floor area of 150,919 sq ft for those buildings. It was built in 2004, 16 years later than 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.

How has The Bonaventure's energy performance changed over time?

What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. The Bonaventure's 26.9 kBtu/ft² across 100,930 sq ft works out to about 2.7 billion Btu (796 MWh-equivalent) in 2024. The disclosure also reports 562,370 kWh of electricity and 7,370 therms of natural gas for the year.

Which law requires The Bonaventure to report its energy use?

The Bonaventure 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:34605917:2024). 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.
