What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. 315 East 187 Street's 99.3 kBtu/ft² across 37,480 sq ft works out to about 3.7 billion Btu (1,091 MWh-equivalent) in 2024.
