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. La Costa Canyon High School's 18.0 kBtu/ft² across 220,429 sq ft works out to about 4 billion Btu (1,163 MWh-equivalent) in 2024. The disclosure also reports 759,910 kWh of electricity and 17,069 therms of natural gas for the year.
Which law requires La Costa Canyon High School to report its energy use?
