Presents the development of core daylighting systems and the characteristics of their collection and transmission components within the building fabric. Discusses the networking of existing and proposed beam daylighting systems relative to the physical impact on a building's major architectural elements. Compares these studies of installed and hypothetical systems to determine projected costs and system efficiencies. Makes recommendations for appropriate building application and suggests directions for future development to help wider acceptance of the concept.KEYWORDS: Lighting, natural lighting, beam lighting, light pipes, costs, economics, feasibility.
