MarOuette Building's ENERGY STAR score of 78 compares with an average of 69 across the 320 that report a score; it scores higher than 60% of them and lower than 36%. Its site EUI of 59.9 kBtu/ft² is about 15% 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 7.2 kgCO₂e/ft² is roughly in line with the group average of 7.5 kgCO₂e/ft².
At 372,265 sq ft, it is about 24% below the average floor area of 488,124 sq ft for those buildings. It was built in 1895, 61 years earlier 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 MarOuette Building's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for MarOuette Building, covering report years 2014, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023. Its ENERGY STAR score went from 65 in 2014 to 78 in 2023 (+13 points). Site EUI moved from 92.0 kBtu/ft² (2014) to 59.9 kBtu/ft² (2023), a 35% decrease. Reported emissions went from 5,980 tCO₂e to 2,672 tCO₂e over the same span (down 55%).
What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. MarOuette Building's 59.9 kBtu/ft² across 372,265 sq ft works out to about 22.3 billion Btu (6,535 MWh-equivalent) in 2023. Its source EUI of 142.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,027,890 kWh of electricity and 9,938 therms of natural gas for the year.
Which law requires MarOuette Building to report its energy use?
MarOuette Building 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:101919:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
