Just as commissioning has been shown to enhance new construction and renovation/retrofit projects, retrocommissioning has been found to be an effective and efficient way to manage and optimize existing system operation. Central chilled/hot water system retrocommisioning (RCX) can be performed before, during, or after building-side HVAC (heating, ventilation, and air-conditioning) system RCX. Successful central chilled/hot water system RCX not only results in improved production and distribution, but it also achieves significant thermal and pump power savings. It quickly evaluates building HVAC system performance for savings opportunities when carried out before building side RCX or serves as a necessary and productive follow-up when performed after. Follow-up is a key factor in the RCX program described here and is needed to maintain the savings and optimized performance of systems.
