What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 falls in band A — high performer (85–100). 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.
