A successful energy management control system using a personal computer (PC) is developed in this paper to avoid wastage of energy by human carelessness. A small residential building model is considered and a PC is used as a tool to monitor the electrical system. Sensors are considered to monitor the number of persons entering or leaving and the computer system switch on/off the electrical equipment, and able to count the number of people in each room in the building. The system continue to count when more people enter the rooms. When all the peoples leave the rooms the system will switch off all the electrical equipments to make sure that there is no wastage of energy.
