What does a site EUI of 2.6 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. Mequity E. 21st's 2.6 kBtu/ft² across 61,957 sq ft works out to about 0.2 billion Btu (47 MWh-equivalent) in 2022. Its source EUI of 7.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 48,109 kWh of electricity for the year.
Which law requires Mequity E. 21st to report its energy use?
