Development of an algorithm for predicting the performance and optimizing the design of an energy efficient lighting system

This paper describes part of the research that is being done on the prediction of the performance of light pipes and the ways to optimize their design, in order to house artificial lighting, able to supplement daylight in a space. The research has up to date resulted in an algorithm for the easy and quick calculation of the interior illuminance provided by light pipes and in a procedure for the calculation of the power of the necessary artificial lighting (LEDs) and the energy savings for lighting, due to the daylight provided by the light pipes and the daylight linked controls of the LEDs.
