What does a site EUI of 152.7 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. 25 E 109th St's 152.7 kBtu/ft² across 11,660 sq ft works out to about 1.8 billion Btu (522 MWh-equivalent) in 2023. Its source EUI of 190.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 57,887 kWh of electricity and 15,833 therms of natural gas for the year.
