What does an ENERGY STAR score of 33 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 33 means the building performs better than about 33% of its national peers. BuildingCensus bands the score into report-card grades; 33 falls in band D — lowest band (1–54). It sits 42 points below 75, the threshold for ENERGY STAR certification. In Chicago, 35% of scored buildings are at 75 or above.
