This dissertation consists in one study on low-impact technologies that use materials such as raw earth, fibers, and vegetal resins. It is part of the research line from PUC-Rio’s Department of Arts and Design’s Laboratory for Investigation in Living Design (LILD). The purpose of this study is the development of objects adopting the LILD s methodology, in which objects are analyzed under two domains: the laboratory, called situational, and the physical-social, encompassing the use of the object, called cultural. When passing from one domain to the other, the object stays under a diversity of its interactions. The analysis of the situational domain furthers the existing knowledge on air permeability and heat transfer through in-lab analyses of honeycomb-shaped clay structures serving as architectonic sealing units as well as experiments with various finishing options to the clay-fiber surface. On the other hand, the aspects of conviviality activities – term by Ivan Illich, 1976, in which learning is enclosed in construction endeavors – are explored in cultural domains located in Rio de Janeiro, Minas Gerais, and Sao Paulo. Several experiences are reported, all of them involving the use of materials like raw earth, and natural fibers and resins, for the development of activities such as the construction of a shelter, a clay oven, and a clay-fiber tunnel, the restoration of a geodesic-structured chapel, the construction of a lattice-structured worm farm, and the renovation of an apartment. The appendix includes a photographic study of construction techniques associated with these materials across the world. Dwellings are seen not only under an anthropologic and construction perspective, but also through the author’s point of view on site during his bicycle tour around the world.
