What does a site EUI of 136.1 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. 611 Madison Ave's 136.1 kBtu/ft² across 29,342 sq ft works out to about 4 billion Btu (1,170 MWh-equivalent) in 2024. Its source EUI of 218.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 373,350 kWh of electricity, 27,188 therms of natural gas and 1,502 thousand gallons of water for the year.
