What does an ENERGY STAR score of 35 mean?

BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient.
