What does a site EUI of 70.4 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. 29 - 31 Smith Place's 70.4 kBtu/ft² across 53,926 sq ft works out to about 3.8 billion Btu (1,113 MWh-equivalent) in 2024. Its source EUI of 143.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 625,626 kWh of electricity, 16,639 therms of natural gas and 3 thousand gallons of water for the year.
Which law requires 29 - 31 Smith Place to report its energy use?
