How has Regatta Condominium Association's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for Regatta Condominium Association, covering report years 2015–2023. Its ENERGY STAR score went from 47 in 2015 to 67 in 2023 (+20 points).

What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 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. Regatta Condominium Association's 70.2 kBtu/ft² across 452,227 sq ft works out to about 31.7 billion Btu (9,304 MWh-equivalent) in 2023. Its source EUI of 118.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,412,571 kWh of electricity and 201,025 therms of natural gas for the year.
Which law requires Regatta Condominium Association to report its energy use?
