Sensor-free automation of buildings to conserve the light energy without sacrifice in the visual comfort through image processing techniques

Automating the buildings leads to efficient operation especially in office workspaces. In buildings, automation is d one mostly on HVAC systems and Lighting systems. Lighting Systems is one area where energy can be conserved. Understanding this many lighting control techniques have been developed for providing automation in Lighting systems. There are many difficulties faced in the automating the buildings, like number of sensors increases with increase in building area, transmitting information and centralized control. The main aim of this paper is automating the lighting systems in the office building to conserve and control light energy without sacrificing the visual comfort through image processing with the help of cameras used for surveillance systems. An added advantage is that we can save the cost of investment in the sensors.
