Abstract

This study investigates whether different lighting types have an effect on the visual performance of office workers. Wall washing, cove lighting and uplighting were tested as they are the most widely used lighting types in offices, after general lighting. The lighting level chosen was 275 lx. The experiments were conducted in a controlled environment with different lighting types. Ninety participants took part in three groups of thirty. The performance measurements for each group were done in different lighting sequences. The data collected were statistically analysed. The effects of age, gender and eye deficiency of the participants on performance were also investigated.
