What does a site EUI of 50.9 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. 225-233 Park Ave South's 50.9 kBtu/ft² across 658,649 sq ft works out to about 33.5 billion Btu (9,825 MWh-equivalent) in 2024. Its source EUI of 112.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,543,492 kWh of electricity, 7,273 therms of natural gas and 13,370 thousand gallons of water for the year.
