Its site EUI of 41.0 kBtu/ft² is about 42% below the average of 70.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.7 kgCO₂e/ft² is about 24% below the group average of 7.5 kgCO₂e/ft².
At 708,981 sq ft, it is about 45% above the average floor area of 488,124 sq ft for those buildings. It was built in 1984, 28 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 150 North Michigan's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 150 North Michigan, covering report years 2014–2023. Its ENERGY STAR score went from 73 in 2014 to 75 in 2023 (+2 points); its best year on file was 2016, at 83. Site EUI moved from 62.0 kBtu/ft² (2014) to 41.0 kBtu/ft² (2023), a 34% decrease. Reported emissions went from 9,135 tCO₂e to 4,064 tCO₂e over the same span (down 56%).
What does an ENERGY STAR score of 75 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Chicago, 35% of scored buildings are at 75 or above.
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. 150 North Michigan's 41.0 kBtu/ft² across 708,981 sq ft works out to about 29.1 billion Btu (8,519 MWh-equivalent) in 2023. Its source EUI of 114.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,512,101 kWh of electricity and 98 therms of natural gas for the year.
Which law requires 150 North Michigan to report its energy use?
150 North 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:101813:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
