What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. 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 New York City, 43% of scored buildings are at 75 or above.
