What does a site EUI of 80.2 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. 2100-06 chestnut's 80.2 kBtu/ft² across 30,000 sq ft works out to about 2.4 billion Btu (705 MWh-equivalent) in 2022. Its source EUI of 167.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 417,521 kWh of electricity, 9,815 therms of natural gas and 10,726 thousand gallons of water for the year.
