The importance of an atrium's skylight is to let the daylight in. However the more area of the skylights you design, the more daylights the indoor can get. Therefore there are some problems occurred for example, the increase of cooling load and discomfort glares. Although there are some studies of the amount of lights in the atrium but the study of evaluating discomfort glare has not been sufficient due to difficulties in selecting observer's location and the direction of occupant's eyes. Accordingly basic data of resolving the glare problem is also insufficient when the atrium is designed. Atrium WI, orientation and PAR are used in this study as various configurations of the atrium and those configurations are compared and analyzed in order to figure out the probability of potential glare in it. As a method for evaluating glare occurrence, the observer's position was fixed in the center of the atrium well and hemispherical view was rendered by the fisheye option of RADIANCE program. Then, find glare command was used to find glare sources and glare index command with DGI (Daylight Glare Index) parameters was used to calculate DGI values. As a result, when the direct sun was viewed from the observer position and the reflection was occurred by a glazing area of its walls the value of DGI was higher than 28, which indicates intolerable glares. Therefore it is judged that if the evaluation of glares is considered by various configurations derived from this study, it can be used as basic data of designing the atrium efficiently without the discomfort glares.
