Possibilities of using lighting simulation tools to predict the level of illumination on the workplace from electric lights

Abstract

Lighting is significant built environment design criteria, and architects or designers always keen to expend efforts to deliver optimal lighting solution. Moreover, the lighting energy consumption represents a significant percentage in a building's energy balance. For these reasons, a suitable way to control the lighting in this field is crucial. The design of control algorithms can be done in various ways, however, in recent years, very useful tools for performing complex lighting assessments are simulation tools. This article deals with a comparison of the results of simulation tools and real measurements and further discusses the possibilities of using these tools to design lighting control algorithms. For the purpose of this paper was used specialized light laboratory where the lighting control is realized via the KNX system. This solution allows the adjustment of luminous intensity and colour temperature for each light separately. Subsequently, the comparison was made for the various configurations of the luminaire settings. © 2018 The Authors, published by EDP Sciences.
