CCD

How does CCD compare with other hospital (general medical & surgical) buildings in Chicago?

The latest disclosures cover 25 hospital (general medical & surgical) buildings in Chicago, out of 3,852 buildings citywide. CCD's ENERGY STAR score of 5 compares with an average of 56 across the 21 that report a score; it scores higher than 5% of them and lower than 90%. Its site EUI of 268.5 kBtu/ft² is about 17% above the average of 229.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 30.2 kgCO₂e/ft² is about 48% above the group average of 20.4 kgCO₂e/ft².

At 1,205,371 sq ft, it is about 31% above the average floor area of 920,964 sq ft for those buildings. It was built in 2013, 47 years later than the group's average year built (1967). Across all 24 jurisdictions BuildingCensus covers, the 748 hospital (general medical & surgical) buildings average an ENERGY STAR score of 59 and a site EUI of 238.7 kBtu/ft².

How has CCD's energy performance changed over time?

BuildingCensus holds 6 Chicago disclosures for CCD, covering report years 2014–2019. Its ENERGY STAR score went from 16 in 2014 to 5 in 2019 (-11 points); its best year on file was 2014, at 16. Site EUI moved from 231.0 kBtu/ft² (2014) to 268.5 kBtu/ft² (2019), an 16% increase. Reported emissions went from 33,903 tCO₂e to 36,452 tCO₂e over the same span (up 8%).

What does an ENERGY STAR score of 5 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 5 means the building performs better than about 5% of its national peers. BuildingCensus bands the score into report-card grades; 5 falls in band D — lowest band (1–54). It sits 70 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. CCD's 268.5 kBtu/ft² across 1,205,371 sq ft works out to about 323.6 billion Btu (94,850 MWh-equivalent) in 2019. Its source EUI of 521.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 43,952,816 kWh of electricity and 21,120 therms of natural gas for the year.

Which law requires CCD to report its energy use?

CCD 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 2019 disclosure (source record chicago:250128:2019). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
