Human factors in retail lighting design: an experimental subjective evaluation for sales areas

Lighting design has direct relations on space perception, visual stimulus, spatial cognition and user behaviour in retail environments. Quantitative and qualitative perspectives in retail lighting design help to attract the customers, play a role on the time spent in the retail environments, experience the built environment and displayed merchandise and create a suitable corporate identity. This study seeks to broaden the body of research on relationships between human preferences and retail lighting design and aims to investigate the impact of human factors in retail lighting design by means of an experimental subjective approach for sales areas, establishing a connection between luminous environment perception, price perception and quality perception of displayed products. This research emphasizes the necessity of an appropriate lighting design strategy for retail environments and its impact on customer’s space perception.
