How does Clargran compare with other hotel buildings in Chicago?

The latest disclosures cover 88 hotel buildings in Chicago, out of 3,852 buildings citywide. Clargran's ENERGY STAR score of 19 compares with an average of 51 across the 77 that report a score; it scores higher than 16% of them and lower than 83%. Its site EUI of 131.4 kBtu/ft² is about 19% above the average of 110.1 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 11.8 kgCO₂e/ft² is about 17% above the group average of 10.1 kgCO₂e/ft².

At 343,240 sq ft, it is roughly in line with the average floor area of 343,808 sq ft for those buildings. It was built in 2013, 34 years later than the group's average year built (1979). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².

How has Clargran's energy performance changed over time?

BuildingCensus holds 9 Chicago disclosures for Clargran, covering report years 2015–2023. Its ENERGY STAR score went from 42 in 2015 to 19 in 2023 (-23 points); its best year on file was 2020, at 80. Site EUI moved from 122.3 kBtu/ft² (2015) to 131.4 kBtu/ft² (2023), an 7% increase. Reported emissions went from 4,900 tCO₂e to 4,034 tCO₂e over the same span (down 18%).

What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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. Clargran's 131.4 kBtu/ft² across 343,240 sq ft works out to about 45.1 billion Btu (13,218 MWh-equivalent) in 2023. Its source EUI of 234.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,532,454 kWh of electricity and 262,196 therms of natural gas for the year.

Which law requires Clargran to report its energy use?

Clargran 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:160151:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
