Abstract 

Lighting simulation is increasingly gaining importance as a tool for energy optimization of modern buildings. Lighting simulation tools are used to see illumination distribution. This paper reviews lighting simulations tools available in market and presents an optimal procedure of obtaining strategic placement of Luminaries, for energy efficient lighting systems, taking advantage of daylight.  A ‘Room model’, accommodating the dynamic features of a daylighting project is built in lighting simulation software DIALux 4.10. Using this tool outputs such as 3D representation, energy evaluation, luminance distribution and table outputs are obtained. These are then used in evaluating the candidate illumination system designs for a room model. Results of three alternative candidate designs or arrangements of commercial available luminaire are presented. Some issues and challenges related to the simulation tools such as time complexity, challenges of sky models, real time control application, validation and time taken by simulation process are discussed in this paper. 

Keywords: Daylighting, lighting simulation, DIALux, room model, energy efficient, CIE sky models
