The latest disclosures cover 1,515 multifamily housing buildings in Chicago, out of 3,852 buildings citywide. Parkside IIB's ENERGY STAR score of 91 compares with an average of 62 across the 1,472 that report a score; it scores higher than 82% of them and lower than 16%. Its site EUI of 47.8 kBtu/ft² is about 34% below the average of 72.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.2 kgCO₂e/ft² is about 28% below the group average of 5.8 kgCO₂e/ft².

At 141,502 sq ft, it is about 31% below the average floor area of 206,097 sq ft for those buildings. It was built in 2016, 45 years later 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 Parkside IIB's energy performance changed over time?

BuildingCensus holds 8 Chicago disclosures for Parkside IIB, covering report years 2016–2023. Its ENERGY STAR score was 91 in both 2016 and 2023. Site EUI moved from 61.6 kBtu/ft² (2016) to 47.8 kBtu/ft² (2023), a 22% decrease. Reported emissions went from 612 tCO₂e to 596 tCO₂e over the same span (down 3%).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 falls in band A — high performer (85–100). 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. Parkside IIB's 47.8 kBtu/ft² across 141,502 sq ft works out to about 6.8 billion Btu (1,982 MWh-equivalent) in 2023. Its source EUI of 83.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 798,744 kWh of electricity and 40,444 therms of natural gas for the year.

Which law requires Parkside IIB to report its energy use?

Parkside IIB 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:253969:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
