ABSTRACT
In the last decades, sustainable aspects of human development as energy savings, comfort, health and life-cycles, led to an increased interest on new insulation materials. Lime-Hemp Concrete (LHC) is a light, porous and hygroscopic insulation material made out of hemp chips mixed with an appropriate lime binder. It can be use either to cover masonry walls or to fill timber frame structures, in old or new buildings. The paper first presents this innovative material on the basis of a thorough literature survey. Laboratory experiments were conducted in the Fraunhofer-Institut for Building Physics and corresponding transport and storage parameters are defined. Dynamical interactions between heat and mass flows in material’s porous structure are then analyzed though numerical simulations.
