Its site EUI of 99.1 kBtu/ft² is about 38% above the average of 72.0 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 6.7 kgCO₂e/ft² is about 16% above the group average of 5.8 kgCO₂e/ft².

At 67,133 sq ft, it is about 67% below the average floor area of 206,097 sq ft for those buildings. It was built in 1964, 7 years earlier than the group's average year built (1971). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has 2941 S Michigan's energy performance changed over time?

BuildingCensus holds 8 Chicago disclosures for 2941 S Michigan, covering report years 2016–2023. Its ENERGY STAR score went from 26 in 2016 to 37 in 2023 (+11 points); its best year on file was 2017, at 47. Site EUI moved from 122.0 kBtu/ft² (2016) to 99.1 kBtu/ft² (2023), a 19% decrease. Reported emissions went from 599 tCO₂e to 448 tCO₂e over the same span (down 25%).

What does an ENERGY STAR score of 37 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 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 points below 75, the threshold for ENERGY STAR certification. 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. 2941 S Michigan's 99.1 kBtu/ft² across 67,133 sq ft works out to about 6.7 billion Btu (1,950 MWh-equivalent) in 2023. Its source EUI of 132.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 319,895 kWh of electricity and 55,589 therms of natural gas for the year.

Which law requires 2941 S Michigan to report its energy use?

2941 S 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:103264:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
