What does a site EUI of 28.7 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. Acton Apts's 28.7 kBtu/ft² across 30,169 sq ft works out to about 0.9 billion Btu (254 MWh-equivalent) in 2025. Its source EUI of 80.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 206,238 kWh of electricity for the year.
