228: On The Bio-Receptive Properties of 3d Printed Clay Tiles: A Methodological Model For Enhancing Moss Colonization Through Geometric Design

This study explores how 3D-printed clay tiles with bio-receptive properties can support sustainable architecture by enhancing thermal regulation and enabling moss growth on façades. The research examines how geometric features influence moss colonization without damaging the substrate. An end-to-end workflow was developed, integrating parametric design, standardized clay extrusion, moss slurry application, and image-based quantification. Eight geometry combinations were tested on 16 fired clay tiles under controlled irrigation over six weeks. Results revealed that horizontal grooves with greater depth retained more moisture and promoted higher moss coverage, while shallow vertical grooves performed poorly. Exposure to indirect daylight significantly increased colonization rates. The study underscores the combined impact of geometry and light on bio-receptivity and highlights the potential of ceramic components in fostering biodiversity, supporting carbon sequestration, and regulating microclimates. All digital fabrication files and analysis tools are openly shared, reinforcing replicability. This work contributes to the development of living façade systems in sustainable building practices.
