A building automation system is a network of "intelligent" control devices used in one or more building
systems, such as HVAC, lighting, and security systems. Building automation systems operate cooperatively to share
building information and control system devices automatically according to programmed logic. Building Automation:
Control Devices and Applications focuses on these control devices and how they work together in common automation
scenarios. This textbook covers the operation, signals, and functions of the senors, acutators, and other control
equipment used in automated systems in commercial buidlings. The textbook is organized by building system, and
each system is explained so that the function and application of each device is clear. The system-based foundation
is then used to discuss the typical interactions between multiple systems in automated buildings.
