What does a site EUI of 21.7 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. 1155 N 1St St's 21.7 kBtu/ft² across 30,720 sq ft works out to about 0.7 billion Btu (195 MWh-equivalent) in 2024. Its source EUI of 27.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 159,805 kWh of electricity, 1,217 therms of natural gas and 414 thousand gallons of water for the year.
