What does a site EUI of 50.1 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. 1234 Massachusetts Avenue NW's 50.1 kBtu/ft² across 258,603 sq ft works out to about 13 billion Btu (3,797 MWh-equivalent) in 2012. Its source EUI of 115.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,086,446 kWh of electricity and 58,368 therms of natural gas for the year.
