What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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. 41-47 56th Street's 97.3 kBtu/ft² across 27,492 sq ft works out to about 2.7 billion Btu (784 MWh-equivalent) in 2024. Its source EUI of 123.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
