Effects of different lighting arrangements on space perception

The idea to improve the quality of lighting design in interior spaces has gained importance in the last years. This experimental study concentrateson the quality of lighting and the relation between lighting arrangements and perception. A room having four different lighting arrangements was prepared and the differences between the perception of the participants under each lighting arrangement was analysed. The results suggested that different lighting arrangements affect perception. Wall washing enhanced the impressions of clarity and order, cove lighting enhanced spaciousness and order and uplighting made the same space relaxing, private and pleasant.
