Its ENERGY STAR score went from 65 in 2014 to 61 in 2023 (-4 points); its best year on file was 2016, at 87. Site EUI moved from 79.0 kBtu/ft² (2014) to 52.7 kBtu/ft² (2023), a 33% decrease. Reported emissions went from 14,538 tCO₂e to 7,182 tCO₂e over the same span (down 51%).
What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. 33 West Monroe's 52.7 kBtu/ft² across 1,085,869 sq ft works out to about 57.2 billion Btu (16,771 MWh-equivalent) in 2023. Its source EUI of 131.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 13,994,920 kWh of electricity and 2,249 thousand gallons of water for the year.
Which law requires 33 West Monroe to report its energy use?
33 West Monroe 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:158184:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
