abstract: Biomimicry is an approach that entails understanding the natural system and designs and mimicking them to create new non-biological systems that can solve human problems. From bio-based material development to biologically inspired designs, architects and designers excelled in highlighting the fascination of integrating the biomimetic thinking process into the modern design that provides more comfortable space in which to live. This thesis explores how historical sustainable strategies from Islamic traditional architecture incorporated natural design system that could now be appropriately applied to interior architecture. In addition, it explores the current existing problems in this field and the possibilities of biomimetic sustainable solutions for existing buildings in the hot dry climate regions of Saudi Arabia. The author concentrates on examining Islamic traditional architecture where the past architects incorporated certain aspects of nature in their construction and through using local resources, built buildings that mitigated heat and provided protection from cold. As a result of completing this research, it was found that there are common characteristics between the traditional Islamic architecture elements and system solutions found in some natural organisms. Characteristics included, for example, evaporative cooling, stuck effect, and avoiding heat gain. However, in the natural world, there is always opportunities to further explore more about the impacts of biomimicry and natural strategies applicable to enhance interior environments of buildings. / Dissertation/Thesis / Masters Thesis Design 2016
