Energy Efficient Lighting System Design for Building

Lighting contributes the highest amount of electricity usage in a building. Generally, lighting will consume from 20% until 50% of the electricity consumption. The efficient and effective use of lighting can offer major energy and cost saving. This research investigates and analyses the energy management in a building and presents the design of energy efficient lighting systems. The first part propose a design of energy efficient lighting which will help users to determine the ideal number of luminaries needed in certain room without reducing the quality of lighting. The design was develop via Matlab. The second part is an audit and cost study to demonstrate the wastefulness of commercial, industrial, residential and community lighting. Based on the study, the design for improvement of current lighting system called Lamp Replacement had been proposed. The major findings in this project are that the energy-efficient lighting design could still be achieved without sacrificing the visual comfort and quality of lighting and replacement of older fixtures with new luminaries can greatly improve efficiency.
