What does a site EUI of 35.8 kBtu/ft² mean?
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. 218 W 40th Street's 35.8 kBtu/ft² across 166,315 sq ft works out to about 6 billion Btu (1,745 MWh-equivalent) in 2024. Its source EUI of 58.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 579,478 kWh of electricity, 39,839 therms of natural gas and 160 thousand gallons of water for the year.
