What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 points below 75, the threshold for ENERGY STAR certification. 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. Los Osos Middle School's 45.7 kBtu/ft² across 83,930 sq ft works out to about 3.8 billion Btu (1,124 MWh-equivalent) in 2024. The disclosure also reports 111,335 kWh of electricity and 30,260 therms of natural gas for the year.
