In 2010, the Chicago Department of Aviation (CDA) performed a consolidated cooling system analysis, which concluded that the replacement of the existing east cooling tower was necessary. Burns & McDonnell led the design of this complex and critical replacement project. Built in 1987, the original cooling tower was frequently unable to achieve full chiller capacity, and the plant operators later added two auxiliary cooling towers to the system to compensate. We designed the new east cooling tower with enhancements with a goal of producing as much cooling tower capacity as possible within the footprint of the existing tower. The east cooling tower serves: Terminal 1, Concourses B and C; Terminal 2, Concourses E and F; and Terminal 3, Concourses G, H, K and L.
Building size: O'Hare International Airport heating and refrigeration plant, which uses the new east cooling tower along with the existing north cooling tower and south cooling tower, has a floor area of approximately 82,000 square feet
Building function and services: Provide cooling system to Terminals 1, 2 and 3 at Chicago O'Hare International Airport
