What does an ENERGY STAR score of 41 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 41 means the building performs better than about 41% of its national peers. BuildingCensus bands the score into report-card grades; 41 falls in band D — lowest band (1–54). It sits 34 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. X279 (OECID: 0201165; BBL: 2031780014)'s 78.6 kBtu/ft² across 93,516 sq ft works out to about 7.4 billion Btu (2,154 MWh-equivalent) in 2024. Its source EUI of 157.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,180,282 kWh of electricity, 33,232 therms of natural gas and 0 thousand gallons of water for the year.
