Direct solar radiation is considered the most important climatic element, which has direct and indirect influences on designing buildings and open spaces. In hot arid regions, like Cairo, the main aim is to reduce the heat load in summer, and to maximize it in winter. The aim of the present comparative study is to determine the shaded area and the quantity of direct solar radiation (on 21 June & 21 December) fall on walls, floors and openings of three courtyards in traditional Islamic houses in old Cairo. For this purpose a network of three traditional courtyards houses has been selected in old Islamic Cairo. The first is Zaynab Khatun house (built 1468AD), the second is Gamal Al-Din Al-Dahaby (built 1637AD), and the third is Es-Sinnari house (built 1794AD).
