What does a site EUI of 96.2 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. 21-01/03 41st Avenue's 96.2 kBtu/ft² across 39,808 sq ft works out to about 3.8 billion Btu (1,122 MWh-equivalent) in 2024.
