What does a site EUI of 31.5 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. 1015 Holdings LLC's 31.5 kBtu/ft² across 48,893 sq ft works out to about 1.5 billion Btu (451 MWh-equivalent) in 2024. Its source EUI of 72.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 318,680 kWh of electricity, 4,508 therms of natural gas and 849 thousand gallons of water for the year.
