Which system focuses on managing HVAC systems, lighting systems, and security systems?

The correct choice is a Facilities Management System because this type of system is specifically designed to oversee and optimize the operations of various physical environments, including the management of HVAC (Heating, Ventilation, and Air Conditioning) systems, lighting systems, and security systems.

A Facilities Management System integrates multiple utilities and services necessary for the efficient operation of buildings and spaces, allowing organizations to manage critical functions like energy usage, comfort, safety, and overall building performance. By coordinating these systems, it enhances operational efficiency and ensures regulatory compliance, leading to improved safety and comfort in the environment being managed.

The other options do not specifically address the management and coordination of all three areas mentioned. A Healthcare Management System is more focused on patient care and administrative processes in medical settings. An Energy System typically deals with generation, distribution, and consumption of energy but does not encompass the broader scope of facilities management. Supply Chain Management Systems prioritize logistics and the flow of goods rather than the operational aspects of facilities. Thus, the Facilities Management System is the most appropriate answer for managing HVAC, lighting, and security systems.
