What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. 4650 Slauson Ave's 21.9 kBtu/ft² across 53,836 sq ft works out to about 1.2 billion Btu (346 MWh-equivalent) in 2024. The disclosure also reports 179,470 kWh of electricity and 5,749 therms of natural gas for the year.

Which law requires 4650 Slauson Ave to report its energy use?
