What does a site EUI of 281.0 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. 8401 FALLBROOK AVE's 281.0 kBtu/ft² across 160,740 sq ft works out to about 45.2 billion Btu (13,237 MWh-equivalent) in 2025. Its source EUI of 674.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 13,406 thousand gallons of water for the year.
