Chicago’s McCormick Place is one of the premier convention facility in North America. McCormick Place consists of four state-of-the-art buildings: the North and South Buildings, the West Building and Lakeside Center and together they attract close to 3 million visitors each year. On August 2, 2007, McCormick Place officials opened yet another addition to the complex, the West Building, also designed by tvsdesign and costing $882 million and completed 8 months ahead of schedule. The publicly-financed West Building contains 470,000 square feet of exhibit space, bringing McCormick Place’s total existing exhibition space to 2,670,000 square feet. The West Building also has 250,000 square feet (23,000 m2) of meeting space, including 61 meeting rooms.

McCormick Place building management required that all of the 3rd party devices in this building were BACnet-based. The building has experienced numerous benefits of communicating using the BACnet protocol, including the chilled water system that is fully automated and delivers chilled water to all other buildings in complex. The piping system is interconnected with the energy center and the chilled water center. The 6 Trane chillers are 1,400 tons each and are capable of generating 26oF glycol to a Brine tank heat exchanger at the Energy Center during non-peak hours, which in turn delivers 34oF glycol to the entire campus during peak hours.
