Study on improving the energy efficiency of office building's lighting system design

Lighting for both functional and decorative purposes is a major consumer of electrical energy. Setting up new power plants to meet growing consumption requirements is not financially viable. In a country with a growing demand for energy, increased efficiency in utilizing the energy is the only way to meet the shortfall. The scope of increasing efficiency exists in the performance improvements of lighting systems, pumps and different processes in industries where engineering techniques can be used to enhance their efficiencies. This paper discusses the performance of different types of lighting installations used in the commercial buildings in UAE and saving in energy consumption in the office lighting applications. The study of different types of lamps used in practice, its suitability and cost effectiveness is highlighted. DIALux simulation software is used to study and evaluate the efficient lighting scheme for the office buildings through the use of different types of lamps.
