What does a site EUI of 65.9 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. 1900 L St: 1900 L Street Northwest's 65.9 kBtu/ft² across 104,858 sq ft works out to about 6.9 billion Btu (2,025 MWh-equivalent) in 2016. Its source EUI of 168.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,462,096 kWh of electricity, 19,199 therms of natural gas and 2,402 thousand gallons of water for the year.
