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. 56 Leonard's 103.0 kBtu/ft² across 478,136 sq ft works out to about 49.2 billion Btu (14,433 MWh-equivalent) in 2024. Its source EUI of 186.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
