What does a site EUI of 34.4 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.

Its source EUI of 74.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 467,368 kWh of electricity, 8,979 therms of natural gas and 1,947 thousand gallons of water for the year.
