Considering density of housing in residentialarea of large cities in Japan, it is very difficultto secure sufficient daylight and lead daylightto whole space in the house. High side lightingis one of solutions for such situation. Andwhen high side windows are designed withopen beain, high side light can be propagatedto lower level through open beam. On theother hand, high side light brings highlightarea on walls or floors. The highlights areaoften appears on walls close to eye level. Thearea may cause glare phenomenon or maylower brightness of surrounding area bycontrast effect. And open beain may causeexcessive inipression of air volume fordetached house. This paper reports designingof diffuse screen to solve these problems.
