What does a site EUI of 54.3 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. 623 S Wabash's 54.3 kBtu/ft² across 206,130 sq ft works out to about 11.2 billion Btu (3,280 MWh-equivalent) in 2023. Its source EUI of 119.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,160,487 kWh of electricity, 38,123 therms of natural gas and 1,178 thousand gallons of water for the year.
Which law requires 623 S Wabash to report its energy use?
623 S Wabash 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:158429:2023).
