What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Bell Rohnert Park (Bl236)'s 38.3 kBtu/ft² across 241,008 sq ft works out to about 9.2 billion Btu (2,705 MWh-equivalent) in 2024. The disclosure also reports 1,019,275 kWh of electricity and 60,099 therms of natural gas for the year.

Which law requires Bell Rohnert Park (Bl236) to report its energy use?

Bell Rohnert Park (Bl236) 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:22866512:2024). 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.
