How has MacLean Center's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for MacLean Center, covering report years 2015–2023. Site EUI moved from 90.4 kBtu/ft² (2015) to 46.9 kBtu/ft² (2023), a 48% decrease. Reported emissions went from 2,703 tCO₂e to 602 tCO₂e over the same span (down 78%).
What does a site EUI of 46.9 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. MacLean Center's 46.9 kBtu/ft² across 237,256 sq ft works out to about 11.1 billion Btu (3,261 MWh-equivalent) in 2023. Its source EUI of 50.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 36,470 kWh of electricity and 109,985 therms of natural gas for the year.
Which law requires MacLean Center to report its energy use?
MacLean Center 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:128798:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
