A new smart control system for energy saving

Abstract

Air-conditioning and mechanical ventilating system (ACMV) and lighting system consume the most electrical energy in Malaysia. In University Malaysia Pahang (UMP), the appliances are sometimes switched on with no occupants and contribute to energy wastage. This paper presents the development of GUI based smart control system for energy saving applications. In our previous research, the data on case study of energy wastage occurrences in a UMP Lecture Hall 13 has been presented. Lecture Hall 13 is often left with lights and airconditioning switched on with no occupants, teaching and learning activities in the class. Therefore a smart design of control system for airconditioning and lighting system is developed to prevent energy wasting. The system is designed to automatically switched off and manually switched on the power supply for air-conditioners and lighting units at pre-defined times or when no user in the room. A graphical user interface (GUI) is designed for setting the control system and switching on and off the appliances manually by using the computer. Our system has been tested and it can be achieved up to 35% electricity energy savings after been implemented in UMP’s lecture halls.
