A big challenge for Austria and the EU is the constantly rising demand of energy.
Energy efficiency measures provide a good way to counteract this development. This work presents energy efficient lighting as a part of energy efficiency measures with a very good cost-benefit-ratio. The history of lighting helps on the understanding of the current market situation. Technical aspects of different lamps are discussed in order to identify the best available lamp for different applications. A lifecycle analysis shows the economical and environmental impact of lighting technologies.
Barriers for energy efficient lighting and measures to overcome those are identified. Scenarios for lighting in Austria based on lamp sales for the domestic sector are developed and discussed in order to complete this work.
