What does a site EUI of 11.6 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. Alexander Book Company's 11.6 kBtu/ft² across 12,250 sq ft works out to about 0.1 billion Btu (42 MWh-equivalent) in 2025. Its source EUI of 27.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 32,118 kWh of electricity and 326 therms of natural gas for the year.
