What does a site EUI of 411.9 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. 12301 Parklawn's 411.9 kBtu/ft² across 49,185 sq ft works out to about 20.3 billion Btu (5,937 MWh-equivalent) in 2024. Its source EUI of 614.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,501,452 kWh of electricity and 151,344 therms of natural gas for the year.
