What does a site EUI of 54.0 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. River City's 54.0 kBtu/ft² across 993,312 sq ft works out to about 53.6 billion Btu (15,720 MWh-equivalent) in 2023. Its source EUI of 113.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,352,437 kWh of electricity and 217,681 therms of natural gas for the year.
Which law requires River City to report its energy use?
River City 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:244102:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
