Abstract
Whereas recent domestic buildings and industrial facilities are being constructed as large as possible, the daylighting systems for the large space have rarely been developed. Domestic situation has been reported as only several small or medium sized daylighting systems have been developed, and the large scaled systems have entirely being imported from abroad. We have developed a large scaled daylighting system for the big space. The developed system have been evaluated in terms of the average system efficiency and daylighting factor. Each results are shown with tabulated experimental data.
