Reported emissions went from 627 tCO₂e to 650 tCO₂e over the same span (up 4%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 falls in band B — above median (70–84). 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. Crystal Springs (Cg43)'s 41.7 kBtu/ft² across 271,144 sq ft works out to about 11.3 billion Btu (3,314 MWh-equivalent) in 2024. The disclosure also reports 1,010,906 kWh of electricity and 79,327 therms of natural gas for the year.

Which law requires Crystal Springs (Cg43) to report its energy use?

Crystal Springs (Cg43) 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:6431666:2024). 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.
