Energy saving in buildings by automation

To maintain power and reduce wastage of energy in a building, an automatic control system is needed. Building automation optimizes energy savings and reduces operating costs, thereby lowering total cost of ownership. Furthermore, it enhances security and convenience. This automation process will also monitor the overall building and identify the place and faults, as and when these occur. The system will work in an intelligent manner. It is faster, reliable, and has less maintenance cost. The system has been designed using PLC. In this paper, a strategic approach is provided with a ladder diagram tested by GE Fanuc PLC.
