What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Montgomery County, 53% of scored buildings are at 75 or above.
