FKEE approaches in solving energy wasting in UMP's lecture halls - part II

It is important to note that air-conditioning and mechanical ventilating system (ACMV) and lighting system consume the most electrical energy in a building in Malaysia. In University Malaysia Pahang (UMP), due to the nature of the buildings, split units air-conditioning systems are used in the faculty office blocks and the lecture halls. It is found that a major portion of the energy consumed came from the lecture hall buildings. The appliances are sometimes switched on when they should be off. This contributes to energy wastage. The energy wasted can be reduced by controlling the appliances and system using a control system while maintaining a comfortable and safe environment in the building. This paper presents the FKEE approaches in solving energy wasting in UMP's lecture hall. In the previous paper, we presented a preliminary case study on energy wastage occurrences in a UMP lecture hall, Dewan Kuliah 13 (DK 13). We found that the DK13 lecture hall is often left with lights and air-conditioning switched on with no occupants. Therefore, in this paper, we propose a design of energy saving control system for air-conditioning and lighting system that can be used in lecture halls to prevent energy wasting.
