What does an ENERGY STAR score of 100 mean?

BuildingCensus bands the score into report-card grades; 100 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 Cambridge, 50% of scored buildings are at 75 or above.
