A financial feasibility study on the cost of procuring Chilled Water from a District Cooling System (DCS) Plant versus the cost for Constructing, Owning, Maintaining and Operating a Conventional In-Building Electric Water-Cooled Chilled Water Plant was carried out. The Building is a 35 storey office building located in Kuala Lumpur. The Chilled Water Supply from the DCS Plant is envisaged for 24 hours daily for a period of 25 years. The Supply Temperature shall be 6.5 ± 0.5 ºC and the Differential Temperature ?T shall be 7 ºC. Using A simple payback period calculation, it was found that the provision of a In-Building Chilled Water System is more economically favorable than procuring Chilled Water from a DCS Plant.
