What does a site EUI of 96.1 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. One Kendall Square's 96.1 kBtu/ft² across 2,705 sq ft works out to about 0.3 billion Btu (76 MWh-equivalent) in 2024. Its source EUI of 269.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 76,171 kWh of electricity for the year.
