What does an ENERGY STAR score of 26 mean?

BuildingCensus bands the score into report-card grades; 26 falls in band D — lowest band (1–54). It sits 49 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. 325 37 West Realty Co's 69.1 kBtu/ft² across 48,843 sq ft works out to about 3.4 billion Btu (989 MWh-equivalent) in 2024.
