What does a site EUI of 2.0 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. 1399-Brooklyn's 2.0 kBtu/ft² across 71,965 sq ft works out to about 0.1 billion Btu (42 MWh-equivalent) in 2024. Its source EUI of 2.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is different.
