Shangri-La Hotel, underwent a major renovation in year 1999. Three chiller plant rooms were incorporated into one centralised chiller plant room, resulting in savings of $1,000,000 in energy bills each year. This enabled the hotel to achieve the BCA EBBA Award as well as the Asian Energy Efficient Award. During the upgrading, Shangri-La Hotel also upgraded its BMS system with monitoring capability. The monitoring system assists the engineering department to keep a close watch on chiller plant room operations and performance, and help the department generate a maintenance and continuous improvement plan.
