Smart Building is an expanding trend in government and customer preferences tied to combating climate change and the need to reduce environmentally harmful emissions. As a result, there is a surging demand for energy-efficient buildings fitted with AI and Internet of Things (IoT) devices. Priorities include energy-efficient building materials, HVAC systems (heating, ventilation, and air conditioning), motion and occupancy sensors, light sensors, and motorized windows. On the other hand, telemetry systems measuring data and gray water recycling systems are used to save water.
