How has Realtor Building's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for Realtor Building, covering report years 2014–2023. Its ENERGY STAR score went from 79 in 2014 to 78 in 2023 (-1 points); its best year on file was 2016, at 84. Site EUI moved from 83.0 kBtu/ft² (2014) to 60.2 kBtu/ft² (2023), a 27% decrease. Reported emissions went from 3,048 tCO₂e to 1,983 tCO₂e over the same span (down 35%).
What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. Realtor Building's 60.2 kBtu/ft² across 324,698 sq ft works out to about 19.5 billion Btu (5,729 MWh-equivalent) in 2023. Its source EUI of 121.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,193,478 kWh of electricity, 86,354 therms of natural gas and 2,419 thousand gallons of water for the year.
Which law requires Realtor Building to report its energy use?
Realtor 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:158438:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
