What does a site EUI of 17.9 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. 23 Grant Avenue's 17.9 kBtu/ft² across 27,620 sq ft works out to about 0.5 billion Btu (145 MWh-equivalent) in 2025. Its source EUI of 38.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 89,791 kWh of electricity and 1,885 therms of natural gas for the year.
