Today, the increasing complexity of urbanization, technological advancements, and societal shifts have disrupted the intrinsic connection between humans and the natural environment, which historically underpinned the development of human settlements. This disconnection has led to growing concerns about its adverse impacts on human health, well-being, and environmental sustainability. Biophilic architecture has emerged as a transformative approach to mediating and reestablishing this fundamental relationship. Biophilic architecture integrates natural elements, patterns, and processes into the built environment to foster a harmonious interaction between humans and nature. However, there remains a pressing need to investigate the principles underlying biophilic architecture systematically, evaluate the extent to which these principles contribute to the sustainability and livability of settlements, and explore how biophilic architecture’s elements manifest in human habitats.
This study aims to address these gaps by employing a comprehensive mixed-method approach. The research begins with an extensive literature review, analyzing foundational theories, key concepts, and contemporary applications of biophilic architecture. This review identifies core biophilic principles, the foundation for developing a theoretical framework tailored to the study’s objectives. These principles encapsulate various dimensions of biophilic design, including physical, psychological, and ecological aspects, which collectively enhance human settlements.
In the quantitative phase of the research, the identified principles are operationalized into measurable constructs by developing a researcher-designed questionnaire. This instrument was meticulously crafted to assess the extent to which biophilic principles are present and effective within the context of Masuleh, an iconic Iranian village renowned for its unique architectural and cultural characteristics. The questionnaire was administered to a diverse sample of residents and visitors in Masuleh, capturing their perceptions and experiences related to integrating natural elements and biophilic principles within the settlement.
The data were analyzed using SPSS, focusing on measures of central tendency and dispersion (e.g., mean and standard deviation) to understand data distribution. Additionally, a one-sample t-test was conducted to evaluate whether the observed mean scores of biophilic principles significantly exceeded a neutral benchmark, thereby assessing the desirability of biophilic architecture in Masuleh.
The quantitative findings reveal a hierarchical significance of biophilic dimensions in Masuleh, ranked from the most to the least prominent. Among these, the connection with nature and natural systems scored the highest (mean = 4.29), underscoring the settlement’s strong integration with its natural surroundings. Other dimensions, such as space (mean = 4.22), complexity and order (mean = 4.16), and visual connection with nature (mean = 4.14), also received high ratings, indicating the prominence of these elements in shaping the settlement’s character. Furthermore, dimensions such as nature comfort (mean = 4.09), preservation and placemaking (mean = 4.08), and the interplay of mystery and risk/danger (mean = 4.04) highlight the intricate balance between functionality, aesthetic appeal, and human experience in Masuleh’s biophilic design.
The dimensions of biophilic management (mean = 3.99), lighting (mean = 3.95), and material connection with nature (mean = 3.92) emphasize the role of sustainable practices and sensory engagement in enhancing the built environment. Additionally, dimensions like biophilic activities and uses (mean = 3.84), prospect and refuge (mean = 3.83), and legibility (mean = 3.66) reflect the importance of creating spaces that support diverse activities, provide psychological comfort, and maintain spatial coherence. Finally, natural forms and shapes (mean = 3.65) highlight the aesthetic and symbolic value of integrating organic forms into architectural design.
The qualitative phase complements these findings by delving deeper into the lived experiences of Masuleh’s residents and visitors. Semi-structured interviews explored the realization of biophilic architecture’s dimensions and elements within the settlement. The narratives collected through these interviews provide rich, contextual insights into the interplay between physical design and human interaction, revealing the cultural, social, and emotional significance of biophilic elements in Masuleh. The qualitative data also illuminate the challenges and opportunities for implementing biophilic principles in similar contexts, offering valuable lessons for practitioners and policymakers.
Overall, the study’s results indicate that Masuleh exemplifies a desirable state of biophilic architecture, with an average score of 4.02 per the one-sample t-test. This finding underscores the potential of biophilic design to enhance the quality of life in human settlements by fostering a deeper connection with nature, promoting sustainability, and enriching the sensory and experiential qualities of spaces.
Building on these findings, the research proposes a set of biophilic architectural design principles to integrate natural elements into human settlements at multiple scales, from individual buildings to broader spatial configurations. These principles offer a practical framework for architects, urban planners, and policymakers to create environments that respect ecological constraints and enhance human well-being. By demonstrating the successful application of biophilic architecture in Masuleh, this study provides a model for replicating such approaches in diverse contexts, paving the way for more sustainable and harmonious human settlements worldwide.
