Abstract: “Natural fibre materials, with bio-sourced characteristics, are advanced materials used in building construction and renovation. They have various advantages, such as good thermal insulation, high moisture buffering, and low impact environmental. Our research focuses on three different natural fibre materials: hemp concrete, wood wool, and sheep wool. Thus, to analyse their hygrothermal behaviour, we provide a numerical simulation and a comparative study.”
