What does an ENERGY STAR score of 65 mean?

BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 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.
