Olympia Lofts Condominium Association's ENERGY STAR score of 82 compares with an average of 62 across the 1,472 that report a score; it scores higher than 69% of them and lower than 30%. Its site EUI of 55.7 kBtu/ft² is about 23% 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 4.3 kgCO₂e/ft² is about 26% below the group average of 5.8 kgCO₂e/ft².

At 104,076 sq ft, it is about half of the average floor area of 206,097 sq ft for those buildings. It was built in 1899, 72 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 Olympia Lofts Condominium Association's energy performance changed over time?

BuildingCensus holds 8 Chicago disclosures for Olympia Lofts Condominium Association, covering report years 2016–2023. Its ENERGY STAR score went from 80 in 2016 to 82 in 2023 (+2 points); its best year on file was 2017, at 86. Site EUI moved from 50.4 kBtu/ft² (2016) to 55.7 kBtu/ft² (2023), an 11% increase. Reported emissions went from 654 tCO₂e to 448 tCO₂e over the same span (down 31%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. Olympia Lofts Condominium Association's 55.7 kBtu/ft² across 104,076 sq ft works out to about 5.8 billion Btu (1,699 MWh-equivalent) in 2023. Its source EUI of 85.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 473,297 kWh of electricity and 41,823 therms of natural gas for the year.

Which law requires Olympia Lofts Condominium Association to report its energy use?

Olympia Lofts Condominium Association 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:254023:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
