Lighting System Design for Commercial Buildings with Higher Energy Efficiency

The power demand increasing year by year have made the worldwide in energy crisis. Therefore proper energy management is required to use the available energy wisely. Lighting system play a role of decorative or functional purposes make it become the biggest energy consumption from total energy consumption. As an engineer, we apply our engineering knowledge to increase the efficiency of current lighting system to solve the problem of inefficiency of energy usage. There were various methodology/approach to have a more energy efficient system. Author came out with the effective method to satisfy both economic and technical requirement for commercial building’s lighting system. Theoretical analysis and simulation of lux level in accordance to Malaysian Standard 1525 using DIALux software have been performed. The appropriate lighting fixture had been selected for suitable usage of the room and the lux simulation were conducted to determine the minimum number of light fixtures required to achieve the minimum lux. Technically a higher energy efficiency lighting system should consume less power consumption, which draw less current from the power supply and achieve higher uniformity of lux achieved.
