What does an ENERGY STAR score of 37 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 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. 48-18 Northern Boulevard's 89.7 kBtu/ft² across 241,993 sq ft works out to about 21.7 billion Btu (6,362 MWh-equivalent) in 2023. Its source EUI of 224.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,276,989 kWh of electricity and 37,137 therms of natural gas for the year.
