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. 45 West 35th Street's 121.7 kBtu/ft² across 95,976 sq ft works out to about 11.7 billion Btu (3,423 MWh-equivalent) in 2024.
