Building automation systems are automatic control systems installed for tracing and controlling all electrical and mechanical devices in the facilities. Their aim is to ensure that the failure or status of these systems are received at one or a few centers and that all of them operate manless in accordance with comfort and service conditions subject to a common scenario. In addition, operating costs
Building automation systems components;
- Central management software
- Digital field controllers (various point capacities and communication properties)
- Field control equipment (dumper and valve actuators, relays, etc.)
- Field measurement devices (sensors, analogue measurement equipment, current relays, etc.)
Systems that can be traced and controlled through building automation systems
- Fans, pumps, engines, air conditioner centers
- Illumination systems
- Energy switching cells (AG, OG), consumer meters
- Boilers, exchangers, heating systems
- Cooling systems
- Fancoil units
- Air flow changing units VAV, VRV
- UPS and generators
- Heat flow meters
Building automation systems’ integration abilities with other systems affect the overall success of the system. Maximum level of open communication protocol support ensures good control of systems and decrease in total possession costs.
A good system should, for example, support BACNET, Modbus, Lonworks, MBus protocols without any additions and can perform these both on RS232/485 serial port and ethernet ports.
The ability of Direct Digital Control systems to support as many disperse cabling structure as possible decreases total cabling costs and cabling errors.
The most important factor affecting the performance of building automation systems is good engineering. Automation system design should commence on the first day when the mechanical systems of the building are designed.
