Abstract :
One of the influential factors in building design is their proper orientation regarding the placement of the sun and the optimal utilization of natural light. Research conducted on buildings constructed in Iran has referred to three orientations (directions): the orientation of urban buildings relative to sunlight, wind direction, and generally the appropriate use of optimal climatic conditions. This article aims to investigate the orientation of courtyard houses in the city of Isfahan, built during the Safavid and Qajar periods, and its impact on the illumination of facades and spaces situated in each direction. The main research question is based on the orientation of houses, both in terms of direction and angle, and how it has affected the illumination of facades and consequently the spaces. The purpose of this research is to study the role of the orientation of houses in the illumination of spaces. The method employed in this study is qualitative research, and data collection utilized both library and field methods, with data analysis conducted using descriptive methods. The results of this research indicate that the orientation of houses on a north-south axis in winter, based on the Isfahan pattern, performs better than other angles for Tehran-style illumination (winter-oriented). However, overall, none of the orientations had a significant impact on facade illumination. Nonetheless, the varied placement angles in historical houses not built according to the Isfahan pattern were not climate-dependent but rather created based on the shape of the land and its axial alignment.
