Shopping malls serve as a primary channel for retail, drive economic growth, and contribute to social and cultural life at a location. They offer a convenient and diverse shopping experience, attract tourism, and contribute to infrastructure development. 

HVAC is one of the most crucial systems of a shopping mall and is integral to successful operations of the shopping mall providing comfortable environment for customers and employees. They ensure optimal temperature which are essential for attracting and retaining shoppers, boosting employee well-being, and maximizing building energy efficiency. 

Research suggests around 50% to 60% of a typical commercial spaces energy consumption comes from HVAC systems, therefore highlighting the need for improved efficiency to reduce carbon emissions and reduce costs. We would like to highlight a case study where we came across a shopping mall with ailing HVAC system.
