This paper has studied the role of air conditioning and lighting system in consumption of electricity of the faculty room (25‟ x 30‟) belongs to Electrical Engineering Department, Kalyani Government Engineering College and suggests the reduction of energy consumption. The reduction of energy consumption is a challenging job without curtailing the facilities. It is an endeavour to optimise the consumption utilising the modern electronic system developed using microcontroller. Here the energy audit is conducted, the area identified, some energy efficient appliances recommended and an efficient Pic-microcontroller based system designed to reduce the consumption and saving in cost.
