What does a site EUI of 177.4 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. Schwartz Hall's 177.4 kBtu/ft² across 191,215 sq ft works out to about 33.9 billion Btu (9,941 MWh-equivalent) in 2024. Its source EUI of 339.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,412,846 kWh of electricity for the year.
