The building and construction sectors are responsible for 39% of global greenhouse gas emissions, but they are among the largest consumers of energy. If all indicators show that demand would be exponential in the future. Decarbonization and reduction of energy consumption in buildings are urgent for environmental preservation and resilience to extreme temperature increases. This article aims to present environmentally friendly bio-sourced insulation as a more sustainable circular economy strategy. However, we present the results of thermal and mechanical characterization of plaster samples with the addition of typha fibers in different proportions. Thus, after having carried out the mechanical traction and compression tests by the press, a thermophysical characterization by the asymmetric hot plane method allowed us to have the conductivity and thermal effusivity of the different samples of plaster binder with 0%, 5%, 10%, 15% and 20% in typha. With these data, we modeled the heat transfer phenomena in a flat wall based on plaster-typha. A numerical resolution of the heat equation by the finite difference method is applied to this model along one dimension. After simulating the calculation code, the results obtained made it possible to know the evolution of the temperature as a function of time and the depth of the wall. In addition, the influence of the exchange coefficients was highlighted on both sides, in order to know the optimal thermal insulation thickness of each sample.
