What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. In Washington, DC, 47% of scored buildings are at 75 or above.
