Design of a tubular skylight system
- Solatube International, Inc., Carlsbad, CA (United States)
Since its introduction to the US market in 1991, tubular skylight provides a solution to the problem of lighting up dark corners in a house. Over the years, design of similar products has emphasized on quantity alone and attention to a range of other equally important issues: efficient collecting system, selection of higher specular reflectance material, seals, distribution and quality of light, was not noted. In this paper, the fundamental design concept of an efficient tubular skylight and the possibility of collimating diffuse light is reviewed. The importance of specular reflectance of the tube material on the performance of tubular skylight is demonstrated. Visual appearance (quality) of transmitted light down the tube is related in part to the yellowness index of various materials. Discussion of adequacy of current building and energy code requirements on tubular skylights is briefly touched on and energy simulation results based on a numerical code are presented.
