Tactile Sustainability: Exploring Sensory Perception in Sustainable Building Design

Abstract

The built environment plays a pivotal role in shaping human behavior, emotions and well-being. Our sensory system demonstrates remarkable sensitivity in perceiving the textures of building walls, even when visual cues are absent. However, while the importance of material texture in the architectural perception is widely acknowledged, there remains a lack of empirical evidence regarding the specific influence of these textures on perceived spaciousness. This research explores the intricate realm of sensory perception within sustainable building design, with a focus on tactile experiences with spaciousness and material selection. Blindfolded participants tactually explored a range of sustainable building materials, including recycled wall putty, bamboo composite board, and rammed earth, characterized by varying textural qualities, smooth finish, semi-rough finish and rough finish respectively. Subsequent experiments introduced thermal stimulation, further enhancing participants' perceptual judgments. Findings demonstrate participants' ability to accurately identify these materials based solely on tactile cues, showcasing a pronounced preference for natural and eco-friendly options. The implications of these findings suggest integrating tactile considerations into sustainable design practices, promoting low-impact materials that offer tactile satisfaction and more spaciousness. These findings advance biophilic design principles, fostering connections with nature through tactile elements inspired by sustainability. Ultimately, the research highlights the significant role of tactile perception in shaping perceptions of sustainability and informs design strategies that prioritize sensory comfort and spaciousness and environmental responsibility in the built environment. These insights contribute to the ongoing evolution of sustainable design practices in the built environment not only meets functional needs but also enhances human well-being and ecological stewardship.
