What does a site EUI of 37.6 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. 747 N LASALLE DR's 37.6 kBtu/ft² across 45,000 sq ft works out to about 1.7 billion Btu (496 MWh-equivalent) in 2020. Its source EUI of 78.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 295,201 kWh of electricity and 6,851 therms of natural gas for the year.
