What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 points below 75, the threshold for ENERGY STAR certification. In Montgomery County, 53% of scored buildings are at 75 or above.
