What does a site EUI of 108.4 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. 5005 MCCONNELL AVE's 108.4 kBtu/ft² across 56,306 sq ft works out to about 6.1 billion Btu (1,789 MWh-equivalent) in 2025. Its source EUI of 303.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,399 thousand gallons of water for the year.
Which law requires 5005 MCCONNELL AVE to report its energy use?
5005 MCCONNELL AVE 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.
