What does a site EUI of 53.8 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. GC 40 West 20th Street-RDA's 53.8 kBtu/ft² across 95,316 sq ft works out to about 5.1 billion Btu (1,503 MWh-equivalent) in 2024. Its source EUI of 116.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,153,650 kWh of electricity and 22,594 therms of natural gas for the year.
