How has 10 South Riverside Plaza's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 10 South Riverside Plaza, covering report years 2014–2023. Its ENERGY STAR score was 88 in both 2014 and 2023.

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 10 South Riverside Plaza's 50.5 kBtu/ft² across 786,938 sq ft works out to about 39.7 billion Btu (11,647 MWh-equivalent) in 2023. Its source EUI of 105.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,960,697 kWh of electricity, 160,050 therms of natural gas and 3,838 thousand gallons of water for the year.
Which law requires 10 South Riverside Plaza to report its energy use?
