What does a site EUI of 19.1 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. 321 Greene Avenue's 19.1 kBtu/ft² across 9,112 sq ft works out to about 0.2 billion Btu (51 MWh-equivalent) in 2024. Its source EUI of 20.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,740 therms of natural gas for the year.
