Its site EUI of 16.3 kBtu/ft² is about 73% below the average of 61.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.9 kgCO₂e/ft² is about 81% below the group average of 4.8 kgCO₂e/ft².
At 62,000 sq ft, it is about 39% below the average floor area of 101,338 sq ft for those buildings. It was built in 1986, 33 years later than the group's average year built (1954).

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. 4715 15th Avenue (1521 48th St)'s 16.3 kBtu/ft² across 62,000 sq ft works out to about 1 billion Btu (296 MWh-equivalent) in 2023. Its source EUI of 17.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 10,104 therms of natural gas for the year.
