What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. Rancho Alamitos High School's 21.4 kBtu/ft² across 156,395 sq ft works out to about 3.3 billion Btu (981 MWh-equivalent) in 2024. The disclosure also reports 982,205 kWh of electricity for the year.
Which law requires Rancho Alamitos High School to report its energy use?
