Evaluation of the correlation between the orientation and sides in Qajar houses of kashan

Climatically, the orientation of the courtyard effectively controls the receipt of renewable energy from wind and radiation. Thus, the type of activity on each side of the courtyard can be affected by the house's orientation. This study aimed to investigate the correlation between the orientation of the courtyard and the number and position of sides in K houses. The study area was the old fabric of Kashan, and its statistical population was Qajar houses in the area of Jalali fortification. The type of research is applied, and the research method is historical. In this study, 20 Qajar houses from the Kashan Cultural Heritage Organization were chosen, each with a distinct orientation, the number of sides, and elongation. Each research variable was investigated through field visits and written sources, and SPSS outputs based on Pearson correlation. This study is innovative in terms of subject matter. The results showed no significant correlation between gradual change of orientation and change in the number or position of sides or elongation, but there are relationships; all cases have a north and south side. In the southwest and southeast orientation, most cases had an east side.
