A DDC BuilBuilding Automation system is a type of building automation system that uses digital controls to manage the environment of a building. This type of system allows for the monitoring and control of temperature, lighting, ventilation, and other systems in a building. The system can be programmed to respond to certain conditions, such as changes in temperature or occupancy levels, and can be used to optimize energy efficiency. The system can also be used to monitor and control security systems, such as access control and video surveillance. DDC BuilBuilding Automation systems are becoming increasingly popular in commercial and industrial buildings, as they provide a cost-effective way to improve energy efficiency and provide a more comfortable environment for occupants.
