How does 345 North Morgan compare with other office buildings in Chicago?
The latest disclosures cover 387 office buildings in Chicago, out of 3,852 buildings citywide. 345 North Morgan's ENERGY STAR score of 69 compares with an average of 69 across the 320 that report a score; it scores higher than 37% of them and lower than 63%. Its site EUI of 42.7 kBtu/ft² is about 39% below 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 5.9 kgCO₂e/ft² is about 21% below the group average of 7.5 kgCO₂e/ft².
At 236,000 sq ft, it is about half of the average floor area of 488,124 sq ft for those buildings. It was built in 2022, 66 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.
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. 345 North Morgan's 42.7 kBtu/ft² across 236,000 sq ft works out to about 10.1 billion Btu (2,953 MWh-equivalent) in 2023. Its source EUI of 117.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,876,861 kWh of electricity and 2,636 therms of natural gas for the year.
Which law requires 345 North Morgan to report its energy use?
345 North Morgan 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:257149:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
