A Building Management System (BMS) is a comprehensive solution designed to monitor, control, and optimize the operational efficiency of a building's infrastructure. It integrates various building services, such as air conditioning (including chiller services), electrical and plumbing systems, painting, carpentry, masonry, and cleaning services, into a unified platform. The primary goal of a BMS is to enhance the comfort, safety, and functionality of a building while minimizing energy consumption and operational costs.
