What does a site EUI of 53.4 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. 1000 South Capitol's 53.4 kBtu/ft² across 310,038 sq ft works out to about 16.6 billion Btu (4,852 MWh-equivalent) in 2024. Its source EUI of 121.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,419,114 kWh of electricity, 48,775 therms of natural gas and 10,563 thousand gallons of water for the year.
