What does a site EUI of 113.5 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. ABC 7LSQ 77W 147C's 113.5 kBtu/ft² across 646,685 sq ft works out to about 73.4 billion Btu (21,511 MWh-equivalent) in 2024. Its source EUI of 266.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 16,009,537 kWh of electricity and 182,115 therms of natural gas for the year.
