What does a site EUI of 46.1 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. 580 RLTY CORP's 46.1 kBtu/ft² across 75,115 sq ft works out to about 3.5 billion Btu (1,015 MWh-equivalent) in 2024. Its source EUI of 85.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 480,171 kWh of electricity and 14 therms of natural gas for the year.
