Its site EUI of 19.5 kBtu/ft² is about 74% 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 2.0 kgCO₂e/ft² is about 61% below the group average of 5.2 kgCO₂e/ft².
At 42,102 sq ft, it is about 58% below the average floor area of 100,951 sq ft for those buildings. It was built in 1911, 41 years earlier than the group's average year built (1952).

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 236-240 West 64 Street's 19.5 kBtu/ft² across 42,102 sq ft works out to about 0.8 billion Btu (241 MWh-equivalent) in 2024. Its source EUI of 48.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 198,025 kWh of electricity, 1,473 therms of natural gas and 3,498 thousand gallons of water for the year.
