Abstract This paper is focused on evaluation of environmental variables for daylight performance improvement in high-rise north facade in urban area. The sensitivity analysis of environmental variables were performed on the basis of previous study. Especially, main environmental variables to be considered were ground surface reflectivity, building mass, building layout type and building distance. The numerical model was developed for evaluation of daylight performance in this study. As a result comparison of our simulation programs and commercial softwares, it was verified that there was no difference between two results. As a passive control techniques, the opposing facade could be given attention by urban designers and planners, as well as by those drawing up building legislation for the urban built environment. It would be desirable and important for users of the built environment, to determine future development from the point of view of how opposing facades affect daylighting. Consequently, application of opposite building is proved to be an effective method for the improvement of daylight performance in high-rise north facade.
