What does a site EUI of 31.6 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. 815 2nd Ave's 31.6 kBtu/ft² across 21,970 sq ft works out to about 0.7 billion Btu (203 MWh-equivalent) in 2025. Its source EUI of 88.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 203,767 kWh of electricity for the year.
