Untersuchungen zur Sonneneinstrahlung und natürlichen Lüftung an einem typischen historischen Wohnhaus in der Altstadt von Dschiddah

Investigations on daylight input and natural ventilation of a typical building in the historic centre of Jeddah.

The traditional domestic architecture of the port town Jeddah, located on the Saudi Arabien west coast, is characterized by unique construction features that have not yet been documented on a current scientific level. An interdisciplinary study of experts in architectural history and building research has illustrated interactions between regional historic building forms and climatic site conditions. The typical three to six-story buildings are made of local coral stone. Apart from this material and certain building geometries, wooden bay-windows response to the particularly humid and hot climate of Jeddah. To explore the physical construction intelligence of this architecture, the solar light and radiation entries and the prevailing air movement conditions are demonstrated by daylight-analyses and airflow simulations applied on the example of a historic townhouse, the residence of the Nawar family.
