What does a site EUI of 23.7 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. 2001 S Street's 23.7 kBtu/ft² across 64,395 sq ft works out to about 1.5 billion Btu (447 MWh-equivalent) in 2024. Its source EUI of 62.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 407,681 kWh of electricity, 1,353 therms of natural gas and 385 thousand gallons of water for the year.
