This research focuses on the study of industrial solid residues from the agro-industry, generated from the processing of barley, a monocotyledonous plant that belongs to the Poacea family. The possibility to become the main raw material of a biomaterial applicable to sustainable habitat is analyzed, since its fireproof and easy adaptability properties would allow to produce boards with mechano-physical benefits similar to those of pine, widely manufactured in Chile. A second aspect was the laboratory experimentation with a natural resin obtained from castor oil, in order to create a fully biodegradable material and contribute to reduce negative environmental impact. The boards were designed and manufactured to be used as coatings for interior spaces, with a finished surface of bare material.. As the input for the ideation process considering the psychological comfort matters for future users, methods of affective engineering were incorporated in the definition of surface formal board features, designing sinuous surfaces that evoke feelings of confort, distraction, tranquility and cozyness. Functionality and aesthetics were complemented in a proposal with productive feasibility and adaptable to the field of sustainable construction.
