What does a site EUI of 5.0 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. 633 West 155 Street's 5.0 kBtu/ft² across 49,500 sq ft works out to about 0.2 billion Btu (73 MWh-equivalent) in 2024. Its source EUI of 13.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 70,450 kWh of electricity and 92 therms of natural gas for the year.
