What does a site EUI of 4.3 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. 329-333 E 21st Street's 4.3 kBtu/ft² across 36,700 sq ft works out to about 0.2 billion Btu (46 MWh-equivalent) in 2023. Its source EUI of 12.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 46,780 kWh of electricity for the year.
