What does a site EUI of 96.1 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. NB:73 Fifth Avenue's 96.1 kBtu/ft² across 52,531 sq ft works out to about 5 billion Btu (1,479 MWh-equivalent) in 2024. Its source EUI of 161.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 532,498 kWh of electricity and 32,312 therms of natural gas for the year.
