Lighting control system for energy management system and energy efficiency analysis

Abstract

Most of the students are not aware of electrical energy consumption and it will lead to the waste of energy. Additionally, energy expenditure for a university on electrical energy consumption is extremely high and its burden the institution to pay the cost. One of the proposals to solve this problem is by implementing an energy management system. The main purpose of this research is to develop an energy management system for the lighting system and to analyze energy efficiency based on energy consumption. In this research, an energy audit and lighting audit has been performed to analyze the performance of the lighting system. Then, energy efficiency measures for the lighting system has been implemented. This implementation involving the replacement of the LED lamp, installation of a motion sensor and the development of smartphone applications. The energy usage has been measured and recorded in the IoT platform for analysis purposes. Based on MS ISO 8995:2005, the lighting system in the campus is in a good performance and followed the standard. By implementing the energy management system, the cost of energy usage can be saved up to 22.82% and the time taken for the payback is 40.589 months. © 2020 IOP Publishing Ltd. All rights reserved.
