Abstract: Energy efficiency and Greenhouse Gases emission reduction are actual key issues in all the economic sectors and, in particular, in the building sector that is one of the most energy-consuming. This paper reports on the performance of sustainable materials produced from natural resources as hemp-concrete or from recycled-waste non-biodegradable materials including Recycled PolyEthylene Terephthalate (R-PET). Three façades employing three different materials (hemp-concrete, hemp-concrete with brick and RPET) were investigated in three cities in France (Nancy and Carpentras) and in Italy (Perugia) with different climates. The energy performance of each façade was assessed in terms of cooling and heating demands, electrical consumptions and indoor thermal comfort including indoor temperature and relative humidity. The effects of two ventilation modes were tested using a constant airflow rate or humidity sensitive flow rate.
