What does a site EUI of 34.1 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. 233 18th Street's 34.1 kBtu/ft² across 34,146 sq ft works out to about 1.2 billion Btu (341 MWh-equivalent) in 2024. Its source EUI of 80.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 255,958 kWh of electricity and 2,903 therms of natural gas for the year.
