What is IBMS?

IBMS is ambiguous. It could potentially refer to Integrated Building Management Systems. These systems are used to control and monitor various aspects of a building, such as HVAC (heating, ventilation, and air conditioning), lighting, security, and energy consumption, all from a central platform. They are used to improve efficiency, reduce costs, and enhance the overall building environment. Without further context, it is difficult to provide a more specific explanation.
