What does a site EUI of 8.1 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. 5 Cowperthwaite Street's 8.1 kBtu/ft² across 98,623 sq ft works out to about 0.8 billion Btu (234 MWh-equivalent) in 2024. Its source EUI of 22.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 234,418 kWh of electricity for the year.
