How has Michigan 30 LLC's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for Michigan 30 LLC, covering report years 2015–2023. Its ENERGY STAR score went from 53 in 2015 to 51 in 2023 (-2 points); its best year on file was 2018, at 85. Site EUI moved from 110.0 kBtu/ft² (2015) to 92.7 kBtu/ft² (2023), a 16% decrease. Reported emissions went from 3,356 tCO₂e to 2,060 tCO₂e over the same span (down 39%).
What does an ENERGY STAR score of 51 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 51 means the building performs better than about 51% of its national peers. BuildingCensus bands the score into report-card grades; 51 falls in band D — lowest band (1–54). It sits 24 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. Michigan 30 LLC's 92.7 kBtu/ft² across 222,125 sq ft works out to about 20.6 billion Btu (6,035 MWh-equivalent) in 2023. Its source EUI of 185.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,262,324 kWh of electricity and 94,668 therms of natural gas for the year.
Which law requires Michigan 30 LLC to report its energy use?
Michigan 30 LLC 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:101968:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
