Study on energy efficient street lighting system design

Today, energy shortage and carbon emission are the major challenges faced by many countries. There are many ways to save energy in every sector thereby reducing the carbon emission and global warming. Qatar, in the Middle East has shown growing demand for electricity consumption. In Qatar, the energy consumption by 2020 is expected to reach 80,648GWh and the energy consumption for lighting alone is expected to be 15,323GWh. Lighting is used in many applications and it is one of the areas that offer many opportunities for improving the energy efficiency thereby reducing the energy consumption. This paper presents a case study on energy efficient street lighting system design for the roadways in Energy City Qatar. Simulation software DIALux4.9 is used to investigate the efficient street lighting scheme through the use of different types of lamps and highlights how the concepts can be visually compared, its cost effectiveness can be studied during the design phase in order for the decisions to be made prior to its implementation. The study has concluded that forty percent reduction in the energy consumption can be achieved with the proposed street lighting system design.
