What does an ENERGY STAR score of 25 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 25 means the building performs better than about 25% of its national peers. BuildingCensus bands the score into report-card grades; 25 falls in band D — lowest band (1–54). It sits 50 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. 247 West 87th Street's 88.4 kBtu/ft² across 268,989 sq ft works out to about 23.8 billion Btu (6,969 MWh-equivalent) in 2024. Its source EUI of 145.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,088,907 kWh of electricity, 139,634 therms of natural gas and 7,697 thousand gallons of water for the year.
