Johnson Controls’ comprehensive building solution has enabled 34-year-old Sun Hung Kai Centre, a 53-story mixeduse development to achieve energy and cost savings of around 10% and reduce its carbon footprint by 300 tons per year. The Centre is among the few buildings in Hong Kong that has achieved the “Excellent” certificate awarded by the Hong Kong Environment Technology Centre. It has also achieved global certification from the International Standards Organization (ISO) for its accomplishments in improving quality and environmental management.

At the center of the Johnson Controls’ project is the optimization of the building’s central chilled water plant, which typically consumes about 40% of the total energy consumption in the building. Now, chillers with different tonnage and starters can be utilized depending on building load and ambient conditions. Johnson Controls also introduced its proprietary fault-diagnostic software, Connected Services, which allows for remote monitoring of chillers round-the-clock. With that, Sun Hung Kai Centre receives real-time information on its chiller plant performance, as well as timely insights through monthly, customized reports indicating the health of the chillers.
