How does The Monadnock Building compare with other office buildings in Chicago?
The latest disclosures cover 387 office buildings in Chicago, out of 3,852 buildings citywide. The Monadnock Building's ENERGY STAR score of 98 compares with an average of 69 across the 320 that report a score; it scores higher than 98% of them and lower than 0%. Its site EUI of 31.8 kBtu/ft² is about half of 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 2.6 kgCO₂e/ft² is about 65% below the group average of 7.5 kgCO₂e/ft².
At 496,749 sq ft, it is roughly in line with the average floor area of 488,124 sq ft for those buildings. It was built in 1890, 66 years earlier 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 The Monadnock Building's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for The Monadnock Building, covering report years 2014–2023. Its ENERGY STAR score went from 97 in 2014 to 98 in 2023 (+1 points); its best year on file was 2016, at 99. Site EUI moved from 50.0 kBtu/ft² (2014) to 31.8 kBtu/ft² (2023), a 36% decrease. Reported emissions went from 2,799 tCO₂e to 1,287 tCO₂e over the same span (down 54%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 falls in band A — high performer (85–100). 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. The Monadnock Building's 31.8 kBtu/ft² across 496,749 sq ft works out to about 15.8 billion Btu (4,630 MWh-equivalent) in 2023. Its source EUI of 51.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,507,880 kWh of electricity, 106,759 therms of natural gas and 2,001 thousand gallons of water for the year.
Which law requires The Monadnock Building to report its energy use?
The Monadnock Building 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:101567:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
