Section 4
Energy Efficient Lighting



Introduction

The purpose of this training material is three-fold.  The first aim is to provide the lighting and allied industry workforce with an overview of the key principles of light and lighting which includes an understanding of basic design concepts and lighting technologies currently available, in the context of sustainability.  The second aim is to help users understand the importance of energy efficiency and the implications of choosing a product in the overall scope of energy consumption. It also aims to assist users with the selection process when specifying, recommending, designing and installing various lighting systems.

In residential dwellings, lighting energy consumption has increased dramatically with the popularity of halogen downlight systems, which are grossly inefficient when compared to the increasing range of residential compact fluorescent lamps (CFLs).  This is an example of where improved lighting design knowledge may lead to more efficient installations.

Qualification as a lighting designer requires a great depth of knowledge in the lighting design process. This is knowledge is acquired through extensive, detailed training, covering a large variety of lighting design applications such as interior lighting, (differentiated into commercial, retail, industrial and residential), floodlighting, emergency and exit lighting, exterior lighting, road lighting, public lighting, facade lighting, and theatre lighting. Detailed design methodology is beyond the scope of this document.

This section introduces the basic concepts of light and lighting, and explores the key requirements of a lighting system and what standards need to be met.  It also explains what we mean by sustainability and energy efficiency and how good lighting design can contribute to these.
