What does a site EUI of 89.6 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. 451 PARK AVENUE's 89.6 kBtu/ft² across 27,000 sq ft works out to about 2.4 billion Btu (709 MWh-equivalent) in 2024. Its source EUI of 207.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 513,917 kWh of electricity and 6,669 therms of natural gas for the year.
