Using the architectural style of heritage buildings as a tool to avoid health risks-An analytical study of Rowshan in traditional houses in the city of Jeddah

摘要

This study considers the importance of window styles known as Rowshan that is found in heritage buildings in the city of Jeddah. The primary objective of this study was to evaluate and compare the use of Rowshan with glass windows for accessing direct sunlight in interior spaces in order to avoid vitamin D deficiencies. It is clear that the use of Rowshan as a design strategy is a relatively simple way for improving vitamin D intake among occupants whilst also ensuring that a residence adheres to the privacy levels that are crucial in Arab and Middle-Eastern countries subjected to some considerations.
