FKEE Approaches in Solving Energy Wasting Occurrences in UMP´s Lecture Halls

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 running on a fixed setting throughout the day, and are sometimes turned 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 a preliminary study on energy wastage in a UMP lecture hall. In this case study, a data logger is installed to collect data for further analysis on energy consumption in the hall. Also reported in this paper is the preliminary design of a energy saving control system for air-conditioning and lighting system that can be used in lecture halls.
