Its emissions intensity of 7.1 kgCO₂e/ft² is roughly in line with the group average of 7.5 kgCO₂e/ft².
At 390,965 sq ft, it is about 20% below the average floor area of 488,124 sq ft for those buildings. It was built in 1968, 12 years later than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 500 N Michigan's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 500 N Michigan, covering report years 2014–2023. Its ENERGY STAR score went from 54 in 2014 to 56 in 2019 (+2 points); its best year on file was 2015, at 70. Site EUI moved from 87.0 kBtu/ft² (2014) to 50.6 kBtu/ft² (2023), a 42% decrease. Reported emissions went from 6,529 tCO₂e to 2,769 tCO₂e over the same span (down 58%).
What does a site EUI of 50.6 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. 500 N Michigan's 50.6 kBtu/ft² across 390,965 sq ft works out to about 19.8 billion Btu (5,798 MWh-equivalent) in 2023. Its source EUI of 141.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,799,863 kWh of electricity and 2,066 thousand gallons of water for the year.
Which law requires 500 N Michigan to report its energy use?
500 N Michigan 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:101935:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
