What does a site EUI of 48.8 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 Avenue's 48.8 kBtu/ft² across 140,512 sq ft works out to about 6.9 billion Btu (2,010 MWh-equivalent) in 2024. Its source EUI of 101.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,097,796 kWh of electricity and 1,515 thousand gallons of water for the year.
