What does an ENERGY STAR score of 32 mean?

BuildingCensus bands the score into report-card grades; 32 falls in band D — lowest band (1–54). It sits 43 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. 465 West 166 Street HDFC's 92.4 kBtu/ft² across 32,750 sq ft works out to about 3 billion Btu (887 MWh-equivalent) in 2023.
