What does a site EUI of 108.7 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. 230 W 125 St's 108.7 kBtu/ft² across 152,805 sq ft works out to about 16.6 billion Btu (4,868 MWh-equivalent) in 2022. Its source EUI of 239.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,215,603 kWh of electricity and 1,763 thousand gallons of water for the year.
