What does a site EUI of 84.6 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. 850 West Jackson's 84.6 kBtu/ft² across 106,056 sq ft works out to about 9 billion Btu (2,630 MWh-equivalent) in 2023. Its source EUI of 237.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,630,586 kWh of electricity for the year.
Which law requires 850 West Jackson to report its energy use?
850 West Jackson reports under the Building Energy Use Benchmarking Ordinance, the legal basis of the Chicago Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record chicago:250142:2023).
