Energy efficient lighting system for building / Wan Norsyafizan W. Muhamad, Zulzilawati Jusoh and Mohamad Yusof Mat Zain

This project presents the design of efficient lighting systems. The main objective of this project is to analyze the energy management in a building and proposed an efficient lighting design. This project was focusing on lighting design, due to lighting contribute the highest amount of electricity usage in a building. Generally, lighting will consume from 20% until 50% of the electricity consumption. Thus, this project will help people to reduce the electricity usage that consumed by the lighting. In this project, there is new software that has been developed by using MATLAB Graphical User Interface (GUI). This software will help user to determine the ideal number of luminaries or lamps needed in a specific place. There are many factors that affect the lighting quality in order to minimize the quantity of lamps. The second part of the software development is the design for improvement of current lighting system. It is called Lamp Replacement which focused on energy efficiency and to the objective is to minimize the operating costs. The determination of saving cost is based on comparison between the old and new (suggested) lighting designs. Thus, from this software it can help users to minimize their electricity usage according to lighting design in a building. Moreover, users are able to determine the minimum lamps used in certain room cr area without reducing the quality of lighting at that place.
