Abstract:Task -Ambient lighting provides energy saving but space surrounding the users can be dim and unpleasant. This study proposed a solution of an additional Surround Layer of light. Though a series of simulated lighting scenarios, it examined illumination requirements, dimensionality and appearance of the space by the use of Vector/Scalar and Task/Vertical Illumination Ratios. They were evaluated under several illuminance requirements, Task-Surround combinations and Surround Light source sizes. The results showed … Show more
