What does a site EUI of 25.9 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. 349 Suydam's 25.9 kBtu/ft² across 43,250 sq ft works out to about 1.1 billion Btu (328 MWh-equivalent) in 2023. Its source EUI of 39.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 88,400 kWh of electricity, 8,172 therms of natural gas and 28,558 thousand gallons of water for the year.
