What does a site EUI of 90.4 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. 806 Massachusetts Avenue's 90.4 kBtu/ft² across 27,999 sq ft works out to about 2.5 billion Btu (742 MWh-equivalent) in 2024. Its source EUI of 161.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 311,513 kWh of electricity, 14,693 therms of natural gas and 144 thousand gallons of water for the year.
Which law requires 806 Massachusetts Avenue to report its energy use?
