What does a site EUI of 60.9 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. Dekalb Hall's 60.9 kBtu/ft² across 24,058 sq ft works out to about 1.5 billion Btu (429 MWh-equivalent) in 2024. Its source EUI of 82.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 79,400 kWh of electricity, 6,762 therms of natural gas and 523 thousand gallons of water for the year.
