What does a site EUI of 38.2 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. PENN 2's 38.2 kBtu/ft² across 1,514,855 sq ft works out to about 57.9 billion Btu (16,959 MWh-equivalent) in 2024. Its source EUI of 95.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 13,876,956 kWh of electricity, 8,264 therms of natural gas and 20,879 thousand gallons of water for the year.
