What does a site EUI of 2.4 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. 20221 PRAIRIE ST's 2.4 kBtu/ft² across 104,448 sq ft works out to about 0.3 billion Btu (73 MWh-equivalent) in 2025. Its source EUI of 3.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 366 thousand gallons of water for the year.
Which law requires 20221 PRAIRIE ST to report its energy use?
20221 PRAIRIE ST reports under LA Municipal Code Div. 97, §91.9701 (EBEWE), the legal basis of Los Angeles's Existing Buildings Energy & Water Efficiency (EBEWE) program, which publishes each covered building's annual benchmarking results.
