A smart building is one that uses automated processes to control its operations, such as heating, ventilation, air conditioning, lighting, and security. Sensors provide feedback, actuators provide control, and gateways connect to the centralized cloud platform. The Internet of Things (IoT) plays an important role in the development of smart and intelligent buildings, providing benefits such as energy optimization, asset management via predictive maintenance, centralised dashboard, occupant comfort compliance, and so on.
