The Development of Design Tools of Daylight Duct Systems for Underground Spaces |
| Abstract |
Daylight duct systems and atria are important and necessary design features for underground spaces which are increasingly developed and utilized to enhance the land use of congested urban areas. However, building designers face obstacles in properly designing those daylighting systems mainly due to the lack of easy-to-useand accurate design/evaluation tools. The goal of this study isto develop design/evaluation tools and guidelines of daylighting systems for underground and/or atrium spaces which can be easily used by building designers in the early stages of design process. The current paper presents daylighting design tools such as graphs, tables and equations for calculating illuminances on the work plane of underground spaces with vertical rectangular daylight duct systems. |
