As significant amount of energy is used for illuminating in educational buildings such as lecture halls and lecture rooms, improvements is needed to avoid energy waste for unoccupied and daylight hour. The lighting will be controlled based on demand to save the energy costs. This paper proposes a concept of smart energy saving classroom system using programmable logic controller (PLC). It integrates the lighting and air conditioner control system. The system is tested in one lecture room in Universiti Teknologi Petronas (UTP), Malaysia. Software for this project includes Simatic Manager, Wincc Flexible and Microsoft Visio 2010.The hardware includes Siemens S300 series PLC, Siemens 10 inch touch screen, network cable and MPI cable. The inputs are sensor at the door and sensors at each of the student seat while the outputs are the projector dc motor, lights, air-conditioner and touch screen. The proposed system offers a costs-saving solution with low maintenance and gives great performance results. {\^A}{\copyright} (2013) Trans Tech Publications, Switzerland.} }
