Abstract

Light trespass has been regarded as one major type of light pollution in urban areas. This study presents an investigation of the impact of six various shading devices on the light trespass risk in a fully glazed office building. Radiance, a ray-tracing package, was adopted to calculate external illuminance levels produced by indoor artificial lighting systems and internal daylight factors under overcast sky condition. It has been found: light shelf performs very well according to both light trespass protection at night and daylighting performance; the shading systems should also be designed to minimize the night light trespass risk in glazed buildings.
