BACnet Veins of Building Automation

Building Automation Training Institute

The simple mathematical word integration makes things easier to understand that we can add several domains in one system.  But picture becomes blurring when we see this to implement to our daily building requirements together. In building automation main domain for working is Climate control (temperature and humidity), safety, public addressing, and security.

Individually we have many systems to perform these tasks but these systems shrinks when intelligent and efficient buildings are in talk. BACnet is a communication protocol for building automation and control network. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform. Proper communication between building automation devices is critical for maximizing building energy efficiency, indoor air quality, and other aspects of "green" buildings.

 In green buildings generally concept come from its individual domains (HVAC, FireDetection Alarm and Suppression, CCTV and Public addressing systems) and its efficient use.

·         Heating Ventilation and Air Conditioning system has work to maintain our ambient temperature at desired value, with certain level of humidity and freshness or air. It includes automatic control of HVAC system i.e. temperature of different   part of Air Conditioning unit and automatic Ventilation. It includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings.

·         Fire is most destructive disaster for life and resources. That is why we use fire detection alarm and suppression system to make our building safer. Detection of fire, Alarm and Suppression should be Automatic so controlling is required.

·         Access Control Authorizes people to operate or access to given area or process, so that this secures our place from unauthorized entry. Access control system can be programmed as per requirement .Access control system can be used in parking area, attendance management, intrusion detection, and to operate automatic doors.

·         CCTV is now a days most common thing for surveillance and its data is useful for many ways .But most of the people are not aware of its wide application. CCTV can be used as face recognition, traffic controller, counter, and high speed detection.

Above domains are key to automatic building but until we do not integrate these systems it would not be efficient and cost effective. For communicating on same platform we use BACnet it integrate these domain and makes things easier.

In building automation many companies have stepped in and there is wide scope for engineers.

Honeywell, Johnson and controls,Schneider, carriermidea ,Bajaj Electricals and many more are looking into this systems .Many projects in India is going on by Johnson and Control, Honeywell  and Bajaj As well.
