What does an ENERGY STAR score of 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. 501 Colorado Ave's 58.1 kBtu/ft² across 91,990 sq ft works out to about 5.3 billion Btu (1,566 MWh-equivalent) in 2022. The disclosure also reports 1,016,898 kWh of electricity and 19,721 therms of natural gas for the year.

Which law requires 501 Colorado Ave to report its energy use?

501 Colorado Ave 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 2022 disclosure (source record california:6399654:2022). 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.
