Perceptions of daylight quality delivered by light transport systems

By Veronica Garcia Hansen, Gillian Isoardi, Evonne Miller and Galyna McLellan


Light Transport Systems (LTS) (e.g lightpipes, fibre optics) can illuminate core areas within buildings with great potential for energy savings. However, they do not provide a clear connection to the outside like windows do,\ud and their effects on people’s physiological and psychological health are not well understood. Furthermore, how people perceive LTS affects users’ acceptance of\ud the device and its performance. The purpose of this research is to understand how occupants perceive and\ud experience spaces illuminated by LTS. Two case studies of commercial buildings with LTS, located in Brisbane, Australia are assessed by qualitative (focus group\ud interviews) and quantitative (measurement of daylight illuminances and luminance) methods. The data from interviews with occupants provide useful insight into the\ud aspects of LTS design that are most relevant to positive perception of the luminous environment. Luminance measurements of the occupied spaces support the perception\ud of the LTS reported by occupants: designs that create high contrast luminous environments are more likely to be perceived negatively.\u
