AEC conducted a study for the City of Columbus to evaluate various options for generating chilled water to serve the cooling needs of several buildings downtown. A base case consisting of decentralized chilled water plants for each building was developed along with three alternatives for central plants. The first alternative is a central plant that would serve all of the buildings on the site whereas the second alternative consists of a central plant to serve City Hall and 120 W. Gay St. only with separate decentralized plant located in the Central Safety Building. The third alternative is a distributed plant concept where each building has its own plant, but all of these plants are all tied together through a common piping system. The base case and alternatives were simulated and compared considering the total cost of ownership over a 20-year life cycle cost.
