Its site EUI of 64.5 kBtu/ft² is about 14% below the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.1 kgCO₂e/ft² is about 21% below the group average of 5.2 kgCO₂e/ft².
At 35,840 sq ft, it is about 64% below the average floor area of 100,951 sq ft for those buildings. It was built in 1957, 5 years later than the group's average year built (1952).

What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 221 East 50th Street - data's 64.5 kBtu/ft² across 35,840 sq ft works out to about 2.3 billion Btu (677 MWh-equivalent) in 2023. Its source EUI of 88.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 123,699 kWh of electricity and 18,904 therms of natural gas for the year.
