What does an ENERGY STAR score of 24 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 24 means the building performs better than about 24% of its national peers. BuildingCensus bands the score into report-card grades; 24 falls in band D — lowest band (1–54). It sits 51 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% of scored buildings are at 75 or above.
