What does an ENERGY STAR score of 63 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 63 means the building performs better than about 63% of its national peers. BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 points below 75, the threshold for ENERGY STAR certification. In California, 65% of scored buildings are at 75 or above.
