What does a site EUI of 86.8 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. 920 Union Street's 86.8 kBtu/ft² across 18,000 sq ft works out to about 1.6 billion Btu (458 MWh-equivalent) in 2022. Its source EUI of 130.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 118,858 kWh of electricity for the year.
