What does a site EUI of 83.7 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. 15 East 84th Street's 83.7 kBtu/ft² across 25,486 sq ft works out to about 2.1 billion Btu (625 MWh-equivalent) in 2024. Its source EUI of 179.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 389,046 kWh of electricity and 8,069 therms of natural gas for the year.
