GAIA is a new eco-sustainable architectural model. The project has been promoted in collaboration with WASP and it was carried out using the technology of 3D Crane WASP printer and natural materials from the landscape nearby. This natural blend of clay, ground sand, rice straw and rice husk can be considered the inspiration to our product RH400-3D. The mixture is a totally natural blend of clay and rice husk that guarantees healthy environment. The concrete result is a high-performance house from the point of view of energy consumption, indeed the house does not need neither heating, nor an air conditioning system; it maintains a balanced and comfortable temperature both during winter, and in summer. The project integrates into a scenario that emphasizes the importance of environmental sustainability. The process of realization only took a few weeks because its masonry has a thickness of 45 cm. Now, based on the data experienced with GAIA, it is possible to imagine and realize new economic scenarios, in which one hectare of cultivated rice is able to produce 100 square meters of built area.
