How has Renaissance Ohare's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for Renaissance Ohare, covering report years 2015–2023. Its ENERGY STAR score went from 40 in 2015 to 68 in 2023 (+28 points); its best year on file was 2020, at 79. Site EUI moved from 122.5 kBtu/ft² (2015) to 95.4 kBtu/ft² (2023), a 22% decrease. Reported emissions went from 4,559 tCO₂e to 2,723 tCO₂e over the same span (down 40%).
What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. Renaissance Ohare's 95.4 kBtu/ft² across 314,254 sq ft works out to about 30 billion Btu (8,786 MWh-equivalent) in 2023. Its source EUI of 172.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,818,889 kWh of electricity and 169,379 therms of natural gas for the year.
Which law requires Renaissance Ohare to report its energy use?
Renaissance Ohare 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:158083:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
