What does a site EUI of 94.6 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. Barnard College's 94.6 kBtu/ft² across 715,513 sq ft works out to about 67.7 billion Btu (19,837 MWh-equivalent) in 2023. Its source EUI of 133.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,130,478 kWh of electricity and 520,366 therms of natural gas for the year.
