What does an ENERGY STAR score of 62 mean?

BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 43-31 Ithaca Street's 81.4 kBtu/ft² across 59,000 sq ft works out to about 4.8 billion Btu (1,408 MWh-equivalent) in 2024.
