Introducion: The spatial experience within museums, as the outcome of the complex interaction between human perception and architectural space, has long been a significant subject of scholarly inquiry. Within this context, natural light plays a fundamental role in shaping spatial perception and aesthetic experience. Despite the extensive body of research addressing spatial and environmental components of museum architecture, in-depth qualitative investigations into the role of natural light in shaping spatial perception-particularly within the theoretical framework of Immanuel Kant’s aesthetics as articulated in the Critique of Judgment-remain limited. Adopting a qualitative and interpretive approach, the present study seeks to elucidate both the how and the why of natural light’s influence on spatial experience and aesthetic perception in the Tehran Museum of Contemporary Art, aiming to clarify the relationship between architecture, spatial experience, and aesthetic values in contemporary cultural spaces.
Methods: This study adopts a qualitative, analytical-interpretive approach and is designed to elucidate the role of natural light in shaping spatial experience and aesthetic perception within the Tehran Museum of Contemporary Art, grounded in the theoretical framework of Immanuel Kant’s aesthetics as articulated in the Critique of Judgment. The study focuses on the interior spaces of the museum, with an emphasis on the interaction between architectural organization and natural light. Data were gathered through environmental observation and a review of architectural documents, including spatial layouts and lighting design strategies. To enhance the credibility and reliability of the findings, data triangulation was applied by cross-validating observations and architectural documents, while preliminary interpretations were further reviewed and confirmed through feedback from experts in architecture and the philosophy of art. Qualitative data were analyzed using thematic analysis within an interpretive-phenomenological framework, through which key concepts such as aesthetic experience, spatial perception, and interaction with natural light were identified and interpreted in relation to Kant’s Third Critique, allowing for an in-depth exploration of the relationships between light, architectural form, and spatial experience.
Results: The study demonstrates that natural light in the Tehran Museum of Contemporary Art functions beyond a mere environmental or physical element, acting as a perceptual-aesthetic construct that gradually, dynamically, and evolutionarily organizes spatial experience. Analysis within the framework of Kantian aesthetics and a phenomenological approach reveals that engagement with natural light occurs across three interrelated layers. The first layer establishes fundamental spatial perception, enabling orientation, boundary recognition, and the overall organization of space. The second layer encompasses phenomenological perception, in which light modulates the appearance of objects, volumes, and spatial configurations through chiaroscuro, luminous tensions, and temporal variations. The third layer realizes a Kantian aesthetic experience, characterized by the free play of cognitive faculties, disinterested judgment, and a sense of purposiveness without purpose. These layers are causally and developmentally linked, with each level creating the conditions for the next. Furthermore, natural light simultaneously activates three perceptual mechanisms: guiding attention and movement, accentuating phenomenological qualities, and facilitating mental-aesthetic release. By proposing a perceptual cycle of light, the study offers an innovative theoretical framework that positions natural light as an active agent in structuring and enhancing aesthetic experience in museum and cultural spaces, with broader implications for architectural design, spatial organization, and experiential quality in diverse artistic environments.
Discussion: Natural light in the Tehran Museum of Contemporary Art functions not merely as a physical source of illumination but as an active perceptual-aesthetic agent that shapes spatial experience. Analysis within the framework of Kantian aesthetics and a phenomenological approach reveals that engagement with natural light unfolds as a gradual, multilayered, and non-linear process. Initially, light structures basic spatial perception by guiding orientation, delineating boundaries, and organizing overall spatial layout. Subsequently, it generates phenomenological qualities-such as transparency, chiaroscuro, luminous tension, and temporal rhythm-that enrich the perception of objects, volumes, and architectural space. Ultimately, natural light facilitates a Kantian aesthetic experience, characterized by the free play of imagination and understanding, disinterested judgment, and a sense of purposiveness without purpose. Serving as a mediating agent, light simultaneously aligns the appearance of artworks with the spatial configuration, fostering deeper contemplation, prolonged engagement, and a balance between navigation, fluid movement, and aesthetic reflection. The study proposes a three-layered conceptual model that integrates spatial perception, phenomenological experience, and aesthetic realization, highlighting the dynamic interaction between light, architectural form, and perceptual experience. This framework offers both theoretical insights and practical guidance for designing natural lighting in contemporary art museums, emphasizing its role as an active contributor to immersive and meaningful spatial experiences.
