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. 50 Gramercy Park North's 58.7 kBtu/ft² across 70,000 sq ft works out to about 4.1 billion Btu (1,204 MWh-equivalent) in 2024. Its source EUI of 124.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 694,752 kWh of electricity, 84 therms of natural gas and 454 thousand gallons of water for the year.
