DEVELOPMENT OF FRAMEWORK FOR LIGHTING SYSTEM EVALUATION

Abstract

Lighting is responsible for about one-fourth of all energy consumption worldwide. This dissertation focuses on interior lighting system in office buildings and proposes a Lighting System Evaluation (LSE) framework with the aims of promoting energy efficient design, protecting the environment and optimally satisfying the functional and human requirements.

Most of the existing lighting system evaluation tools focus on one or two specific area and requires time and certain level of professional knowledge on lighting system. Local Green Mark Scheme does not cover all the essential factors that affect the lighting system performance.

With the help of LSE tool, the user is able to get feedbacks on how the newly installed system performs or whether there is a need to retrofit or change the existing system. In addition, the tool can also be used as a guideline for the building owner to generate their system requirements when they approach to any lighting system suppliers or contractors. The proposed LSE framework is implemented in a software tool to provide a graphical user interface to enhance and automate applications. The validity and usability of the developed LSE framework is examined by conducting a case study of Zero Energy Building in Building and Construction Authority (BCA) Academy. However, it has to be highlighted users may need to do intensive study to check whether the system fulfils all the requirements set by local authorities as LSE framework only considers all the relatively more essential factors.
