Energy and Economic Sustainable Illumination Design for a Gymnasium: A Case Study

Abstract

Gymnasium lighting design is crucial to provide better visibility, improve overall mood and serve a good experience to the occupant. Conventional artificial lighting might serve these well, but it consumes a significant amount of energy. In this report, a sustainable lighting design for a gymnasium at Taylor's University, Subang Jaya, Malaysia, is developed per the SIRIM 33:2019. The aims are to provide better energy-efficient and sustainable lighting design solutions while maintaining good visibility, overall mood, and meeting the required illumination level. The design is developed in a 3D lighting simulation software, the DIALux Evo 10. The proposed LED lighting design is compared with the existing high-pressure sodium high-bay lighting system. Criterion such as the illuminance level, glare rating index, colour rendering, energy performance and economic assessment are analysed. Result of the analysis shows that the proposed LED luminaires achieved of 68% potential energy consumption reduction, a payback period of 4.9 years and an annual life cost cycle of RM 1, 345.76, compared to the existing fluorescent luminaires' annual life cost cycle of RM 3,570.29. This shows that LED luminaires have better energy performance, and improved cost saving while producing better illuminance level output. The outcome of this study can be considered for future gymnasium lighting design to achieve energy and economic sustainability.
