| Abstract |
This study examines the influence of lighting systems on the visual and spatial satisfaction for small office spaces. Two small office spaces were modeled using a software utilized for practical lighting designs. Direct and indirect lighting systems were applied to the space to provide a target illuminance of 650 lx. The modeled space were projected on a screen in a classroom and evaluated by 18 participants. Results indicate that the indirect lighting was effective to keep space bright and decorative. The indirect lighting contributed to sense the space spacious and mitigate the perception of contrast in space. The levels of psychological, visual and spatial satisfaction for space with the indirect lighting were superior to those under the direct lighting. Those sensations were mainly influenced by visual comfort, satisfaction with lighting, light distributions and illuminance levels. |
