Abstract
The purpose of this paper was development of modified horizontal daylight duct for reflector of light intake, location of outlet diffuser and size as applicable daylighting system for buildings and, verified applicable possibility base on analysis of daylighting performance through full-scale model test. Experimental result showed that ratio of illumination for light duct was measured 0.3∼0.4% in interior of a room on clear sky. Also, light duct had wide distribution of illumination than duct about 150[cm] and was decided efficient lighting energy saving because of high daylight performance in case of application actual building during daytime.
