Kurzfassung englisch:
In 2014, the historic city center of Jeddah on the West coast of Saudi Arabia attained world heritage status for its traditional residential architecture of three-to-six-story high coral stone buildings with horizontal wooden beams for pressure distribution. Today those unique domestic buildings are at risk of deterioration. A combination of high levels of humidity and heat characterize the climate of the port town of Makkah. The facades, with their projected screened windows made of wood are a particularly striking element of the traditional Jeddah houses. Unfortunately, there is very little in terms of advanced building documentation of the local architecture, including in-depth analysis of the historic structure as well as an understanding of daylight input and natural ventilation as important formative factors. However, a recent interdisciplinary study by experts in history of architecture and building archaeology, including daylight studies and airflow simulation, made it possible to test building parameters and the smartness of building physics in a house that represents a typical middle class residential building of old Jeddah. The selected object, Al Nawar house, is situated in the heart of the historic city center, and the oldest original parts of the house are approximately 300 years old. An integrated high-tech building survey was used to make a detailed examination of the architecture and structure of the object. Afterwards, a physical model on a scale of 1:20 permitted physical testing to be done in the light laboratory. Additional curl- and ventilation-simulation programs were applied to shed light on the complex interplay between natural ventilation and burning solar radiation heating up some of the surfaces of the building volume. The results of the study show the variety of physical principles used in the intelligent original design. They are used in the architecture of that traditional house to tailor it perfectly to the needs of its inhabitants and provide for their comfort.
