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. Battery Maritime Building's 249.0 kBtu/ft² across 157,426 sq ft works out to about 39.2 billion Btu (11,488 MWh-equivalent) in 2024. Its source EUI of 418.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,145,673 kWh of electricity and 250,511 therms of natural gas for the year.
