What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 points below 75, the threshold for ENERGY STAR certification. In California, 65% of scored buildings are at 75 or above.
