Its site EUI of 65.5 kBtu/ft² is roughly in line with the average of 70.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 8.8 kgCO₂e/ft² is about 17% above the group average of 7.5 kgCO₂e/ft².
At 1,364,257 sq ft, it is about 179% above the average floor area of 488,124 sq ft for those buildings. It was built in 2009, 53 years later than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 353 North Clark's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 353 North Clark, covering report years 2014–2023. Its ENERGY STAR score went from 85 in 2014 to 76 in 2023 (-9 points); its best year on file was 2014, at 85. Site EUI moved from 71.0 kBtu/ft² (2014) to 65.5 kBtu/ft² (2023), a 8% decrease. Reported emissions went from 18,477 tCO₂e to 11,964 tCO₂e over the same span (down 35%).
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 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. 353 North Clark's 65.5 kBtu/ft² across 1,364,257 sq ft works out to about 89.4 billion Btu (26,189 MWh-equivalent) in 2023. Its source EUI of 175.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 24,368,394 kWh of electricity, 62,140 therms of natural gas and 19,067 thousand gallons of water for the year.
Which law requires 353 North Clark to report its energy use?
353 North Clark 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:158133:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
