Corinthian Condominium Association

How does Corinthian Condominium Association compare with other multifamily housing buildings in Evanston?

The latest disclosures cover 172 multifamily housing buildings in Evanston, out of 366 buildings citywide. Corinthian Condominium Association's ENERGY STAR score of 76 compares with an average of 71 across the 149 that report a score; it scores higher than 43% of them and lower than 56%. Its site EUI of 86.4 kBtu/ft² is about 14% above the average of 75.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.6 kgCO₂e/ft² is roughly in line with the group average of 5.7 kgCO₂e/ft².

At 41,800 sq ft, it is about half of the average floor area of 80,265 sq ft for those buildings. It was built in 1942, 7 years earlier than the group's average year built (1949). 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.

What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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 Evanston, 45% 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. Corinthian Condominium Association's 86.4 kBtu/ft² across 41,800 sq ft works out to about 3.6 billion Btu (1,058 MWh-equivalent) in 2019. Its source EUI of 107.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 118,893 kWh of electricity, 32,046 therms of natural gas and 1,252 thousand gallons of water for the year.

Which law requires Corinthian Condominium Association to report its energy use?

Corinthian Condominium Association reports under the Healthy Buildings Ordinance (1-O-25), the legal basis of Evanston's Building Energy and Water Use Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2019 disclosure (source record evanston:102451:2019). Evanston's Healthy Buildings Ordinance (1-O-25) requires buildings of 20,000 sq ft or more to benchmark and report energy and water use by June 30 each year; the city says non-compliance fines of $250 per month begin January 1, 2027.
