What does an ENERGY STAR score of 47 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 47 means the building performs better than about 47% of its national peers. BuildingCensus bands the score into report-card grades; 47 falls in band D — lowest band (1–54). It sits 28 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. 235-245 Ft Washington Ave's 91.3 kBtu/ft² across 132,297 sq ft works out to about 12.1 billion Btu (3,540 MWh-equivalent) in 2024.
