Berjaya Times Square is one of Kuala Lumpur’s most iconic mixed-use developments, encompassing approximately 700,000 m² of retail, office, hospitality, and entertainment space. Welcoming more than two million visitors every month, the complex relies on a highly dependable cooling system to maintain comfort and operational efficiency.

After more than 20 years of operation, the existing chiller plant faced significant challenges. The aging system operated at an efficiency level of 1.08 kW/RT, with daily electricity consumption reaching as high as 65 MWh. Multiple chillers and cooling towers had reached the end of their service life, resulting in declining performance, reduced reliability, and increasing operating costs.

To modernize the facility’s cooling infrastructure, Berjaya Times Square selected Midea’s high-efficiency chiller solution as part of a comprehensive retrofit project. Despite a demanding schedule and global logistics challenges, the project was successfully completed before the peak Chinese New Year shopping season.

Today, Berjaya Times Square serves as a proven reference project demonstrating how advanced chiller retrofit solutions can help large commercial buildings reduce energy consumption, improve system reliability, and support long-term sustainability goals.
