What does a site EUI of 401.0 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. 300 Norfolk Street's 401.0 kBtu/ft² across 56,672 sq ft works out to about 22.7 billion Btu (6,660 MWh-equivalent) in 2024. Its source EUI of 558.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 218,973 kWh of electricity, 30,707 therms of natural gas and 136 thousand gallons of water for the year.
Which law requires 300 Norfolk Street to report its energy use?
