What does a site EUI of 42.3 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. East Building's 42.3 kBtu/ft² across 96,565 sq ft works out to about 4.1 billion Btu (1,197 MWh-equivalent) in 2024. Its source EUI of 118.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,195,762 kWh of electricity for the year.
