What does a site EUI of 184.9 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. Memorial Hall's 184.9 kBtu/ft² across 18,524 sq ft works out to about 3.4 billion Btu (1,004 MWh-equivalent) in 2024. Its source EUI of 372.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 556,274 kWh of electricity, 9,116 therms of natural gas and 403 thousand gallons of water for the year.
