An Evidence-Based Assessment of Biophilic Interior Design in a Traditional Context: The Case of the Kingdom of Saudi Arabia

Biophilia is a concept that suggests humans have an innate connection to nature. Biophilic design needs to be addressed under the umbrella of environmentally sustainable design, which is crucial in regard to the current urban development agenda. The Kingdom of Saudi Arabia, as a Gulf country possessing valuable traditional architecture with rich local diversity, also needs to implement strategies for the establishment of sustainable development goals. The evaluation of biophilic design in the interior design environment through the values of traditional architecture can be a positive step towards reconnecting the built environment with nature. Within this scope, after a theoretical evaluation of biophilia, biophilic design (BD), and existing BD frameworks, in this study, we used the Biophilic Interior Design Matrix (BID-M) to assess biophilia in traditional Saudi architecture. Three heritage buildings in each of the four regions, amounting to twelve buildings in total, were rated for each of the BID-M matrix’s 54 listed features. According to the findings of a quantitative assessment based on the qualitative evaluation of biophilia in the chosen heritage buildings, these traditional buildings have a remarkably high score regarding biophilia. As such, there is a clear indication of the potential for aligning heritage building values with biophilic interior design features. This new approach, uniquely tailored to the rich and diverse cultural identity of the Kingdom of Saudi Arabia, is crucial for incorporating sustainability into modern construction and has significant implications for the future of architecture in this region.
