What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. 28624 Witherspoon Parkway's 6.5 kBtu/ft² across 209,774 sq ft works out to about 1.4 billion Btu (400 MWh-equivalent) in 2023. The disclosure also reports 399,788 kWh of electricity for the year.

Which law requires 28624 Witherspoon Parkway to report its energy use?

28624 Witherspoon Parkway 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.
