What does a site EUI of 97.9 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. 3500 Dekalb Avenue's 97.9 kBtu/ft² across 29,890 sq ft works out to about 2.9 billion Btu (858 MWh-equivalent) in 2024. Its source EUI of 161.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 292,522 kWh of electricity, 19,289 therms of natural gas and 4,177 thousand gallons of water for the year.
