【 摘 要 】

Prismatic film glazing has the potential to improve indoor illuminance levels and uniformity. Indoor illuminance distributions with prismatic film glazing in a manufacture building were measured. The measured illuminance data with prismatic film glazing were compared to Radiance simulation results with conventional glazing. This study shows that using prismatic film glazing at side windows can improve indoor illuminance levels and illuminance uniformity for inner spaces. The technology can work effectively for large depth spaces under sunny sky but only has slightly better performance under overcast sky.
