What does an ENERGY STAR score of 43 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 43 means the building performs better than about 43% of its national peers. BuildingCensus bands the score into report-card grades; 43 falls in band D — lowest band (1–54). It sits 32 points below 75, the threshold for ENERGY STAR certification. In Boston, 52% of scored buildings are at 75 or above.
