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. 147 W 43rd St's 481.1 kBtu/ft² across 30,150 sq ft works out to about 14.5 billion Btu (4,251 MWh-equivalent) in 2024. Its source EUI of 679.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 882,364 kWh of electricity, 114,949 therms of natural gas and 9,229 thousand gallons of water for the year.
