What does a site EUI of 0.0 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. 51-69 First Street's 0.0 kBtu/ft² across 7,321 sq ft works out to about 0 billion Btu (0 MWh-equivalent) in 2024. Its source EUI of 0.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is different. The disclosure also reports 0 kWh of electricity and 10 thousand gallons of water for the year.
