Aberdeen

How does Aberdeen compare with other mixed use property buildings in Chicago?

The latest disclosures cover 40 mixed use property buildings in Chicago, out of 3,852 buildings citywide. Aberdeen's ENERGY STAR score of 70 compares with an average of 59 across the 11 that report a score; it scores higher than 55% of them and lower than 36%. Its site EUI of 66.4 kBtu/ft² is about 32% below the average of 98.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 6.3 kgCO₂e/ft² is about 38% below the group average of 10.1 kgCO₂e/ft².

At 155,000 sq ft, it is about 78% below the average floor area of 689,510 sq ft for those buildings. It was built in 2018, 49 years later than the group's average year built (1969). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

How has Aberdeen's energy performance changed over time?

BuildingCensus holds 6 Chicago disclosures for Aberdeen, covering report years 2018–2023. Its ENERGY STAR score went from 71 in 2021 to 70 in 2023 (-1 points); its best year on file was 2021, at 71. Site EUI moved from 71.9 kBtu/ft² (2021) to 66.4 kBtu/ft² (2023), a 8% decrease. Reported emissions went from 1,008 tCO₂e to 972 tCO₂e over the same span (down 4%).

What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 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. Aberdeen's 66.4 kBtu/ft² across 155,000 sq ft works out to about 10.3 billion Btu (3,016 MWh-equivalent) in 2023. Its source EUI of 125.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,433,282 kWh of electricity and 54,083 therms of natural gas for the year.

Which law requires Aberdeen to report its energy use?

Aberdeen 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:255946:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
