What does a site EUI of 134.1 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 252.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,701,853 kWh of electricity, 16,523 therms of natural gas and 6,223 thousand gallons of water for the year.
