What does a site EUI of 47.3 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. One Madison Avenue's 47.3 kBtu/ft² across 1,339,997 sq ft works out to about 63.4 billion Btu (18,575 MWh-equivalent) in 2024. Its source EUI of 120.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 15,892,391 kWh of electricity, 91,508 therms of natural gas and 10,705 thousand gallons of water for the year.
