What does a site EUI of 31.5 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. Uptown 11's 31.5 kBtu/ft² across 75,494 sq ft works out to about 2.4 billion Btu (697 MWh-equivalent) in 2025. Its source EUI of 88.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 419,122 kWh of electricity for the year.
Which law requires Uptown 11 to report its energy use?
