Energy Efficient Building Automation Systems Using Protocols and Control Methods

In recent years, due to the energy crises, the recognition of energy sources is limited and there is the tendency to have cleaner and comfortable environment leading to development in using energy as optimally as possible. The key driver of the building automation market is the promise of increased user comfort at reduced operation cost. Building Automation Systems (BAS) provide automatic control of the conditions of indoor environments. In the past few years, many researchers have been done on application, structure and also efficiency of different methods to achieve saving more energy. However, selecting technologies and using them effectively is a true challenge. The initial cost and maintenance of the control system is the main criteria for selecting a control system from the point of view of customer or building owner. In this paper, lighting control systems, security control and HVAC control systems using different protocols and methods as a part of building automation are studied along with their advantages and disadvantages. The paper gives concluding remarks on the most commonly used protocols and control methods for building automation.
