How has The Brownstone Condominium Association's energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for The Brownstone Condominium Association, covering report years 2016–2023. Its ENERGY STAR score went from 93 in 2016 to 39 in 2023 (-54 points); its best year on file was 2016, at 93. Site EUI moved from 54.5 kBtu/ft² (2016) to 91.2 kBtu/ft² (2023), an 67% increase. Reported emissions went from 1,094 tCO₂e to 661 tCO₂e over the same span (down 40%).
What does an ENERGY STAR score of 39 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 39 means the building performs better than about 39% of its national peers. BuildingCensus bands the score into report-card grades; 39 falls in band D — lowest band (1–54). It sits 36 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. The Brownstone Condominium Association's 91.2 kBtu/ft² across 100,000 sq ft works out to about 9.1 billion Btu (2,673 MWh-equivalent) in 2023. Its source EUI of 131.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 594,218 kWh of electricity and 70,966 therms of natural gas for the year.
Which law requires The Brownstone Condominium Association to report its energy use?
The Brownstone 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:241410:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
