What does a site EUI of 57.2 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. 950 Massachusetts Avenue's 57.2 kBtu/ft² across 137,010 sq ft works out to about 7.8 billion Btu (2,297 MWh-equivalent) in 2024. 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 1,174,026 kWh of electricity, 38,312 therms of natural gas and 4,442 thousand gallons of water for the year.
