Abstract: Alternative products such as green materials are either back or newly implemented in the construction field. The low environmental impact of hemp concrete and its thermo-hydric behaviour show the possibilities of healthier construction and let obtain a better comfort of users. In contrast with usual concrete, the hemp concrete has huge hygroscopic buffer capacity. The aim of this work is to study the hempcrete with prompt natural cement, which is a concrete block made of a mixture of hemp shivs and “Prompt natural cement”. For that, its behaviour in energy consumption and comfort at a wall and building size level are analysed thanks to simulation and experimental measurements, which are conducted in parallel. Experimental tests have been run at wall scale in two PASSYS test facilities. Test walls are subject to weather solicitations outside and hydrothermal regulation inside. For numerical study, a 2D coupled heat and moisture transport model is defined. Numerical analysis gives results in the same trends as experimental data.
