From Threshold to Perception: An Analysis of the Legibility of Child-Centered Biophilic Spaces in Sustainable Architecture through a Phenomenological and Fuzzy Logic Approach

Biophilic architecture, as an innovative approach to architectural design, emphasizes the deep connection between humans and nature. In child-centered environments, it plays a crucial role in enhancing mental health, improving well-being, and enriching children’s lived experiences. Despite its significance, comprehensive and integrative studies that precisely evaluate the legibility and perceptual quality of such spaces remain limited and often rely on one-dimensional approaches. This research aims to analyze the legibility of child-centered biophilic spaces within the framework of sustainable architecture by adopting a combined approach of phenomenology and fuzzy logic. The research methodology includes qualitative analysis focusing on children’s lived experience and embodied perception of space, along with the use of fuzzy logic to quantitatively model the complexities and uncertainties of spatial perception. In this way, while preserving the richness of qualitative data, it also allows for precise quantitative analysis. Findings indicate that biophilic spaces with high spatial legibility not only facilitate children’s orientation and understanding of the environment but also enhance psychological comfort, strengthen social interactions, and improve the quality of their lived experience. This is achieved through the integration of natural elements, clear visual cues, and an organized spatial structure. The present study provides a scientific and practical framework for designing child-centered spaces that can significantly contribute to sustainable architecture, resource conservation, and the promotion of children’s mental health. Moreover, the integration of philosophical and quantitative approaches deepens the understanding of the complexities of children’s spatial perception. The study suggests that future designs should pay special attention to spatial legibility, the incorporation of cues aligned with children’s perception, the use of diverse natural materials and colors, and the application of innovative technologies to enhance environmental quality.
