| summary |
Global challenges warrant the rethinking of current housing solutions to provide adequate and affordable shelter for inhabitants. This paper presents an approach for the design and digital fabrication of an earthen wall. The paper reports on a 3-day workshop setting that examined how traditional knowledge of vernacular architecture in combination with biomimicry principles, computational design to enable building-scale additive manufacturing that shade itself and effectively responds to the environment and climate. The study explored innovations in computational tool path design for 3D printing, local material recipe, thermodynamic, environmentally responsive earthen wall, fenestration, airflow, non-planarity and verticality, structure, mass customization, stability, passive design strategies on how to build with local earth materials. In preparation for the workshop, 1:20 glazed ceramic prototypes were 3D printed. The experiments involved sourcing local materials, testing various earth mix recipes, finding an appropriate earth mix recipe for a viscosity that could be 3D printed, calibrating the 3D printer and pumping equipment, and printing the final 1:1 wall segment. The material selected for this study was cob, a mixture consisting of clay, sand, vegetation fibre and water, Locally sourced earth material; no transportation required, hence referred to as km-0 material. The motivation of conducting the research is to increase the sustainability, affordability and durability of construction processes. |
