What does a site EUI of 44.0 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. Post Massachusetts Avenue's 44.0 kBtu/ft² across 237,796 sq ft works out to about 10.5 billion Btu (3,066 MWh-equivalent) in 2012. Its source EUI of 111.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,980,167 kWh of electricity and 37,119 therms of natural gas for the year.
