What does a site EUI of 24.2 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. 145 Brattle Street's 24.2 kBtu/ft² across 35,910 sq ft works out to about 0.9 billion Btu (255 MWh-equivalent) in 2024. Its source EUI of 39.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 87,494 kWh of electricity, 5,688 therms of natural gas and 110 thousand gallons of water for the year.
