What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 1113 Rancho Frontera Ave's 8.0 kBtu/ft² across 91,680 sq ft works out to about 0.7 billion Btu (215 MWh-equivalent) in 2024. The disclosure also reports 47,998 kWh of electricity and 5,741 therms of natural gas for the year.

Which law requires 1113 Rancho Frontera Ave to report its energy use?
