Title:Towards the low-cost housing through using recycled materials as an exterior thermal insulation

Abstract:Recycled materials had recently been reintroduced into the research of sustainable materials to combat climate change. this type of Insulating materials for the envelope is mainly characterized by their favorable thermal properties. This research aims to examine the thermal properties and energy performance of dry straw and pulp construction insulation boards, which are local products specific for the arid and semi-arid region of Algeria. The research methodology consists of two parts: the first is experimental, based on a fabrication of insulating plates and tested using thermal conductivity. the second part expresses a series of energy simulations of buildings via TRNSYS and Design Builder software. Subsequently, the thermal performance of the envelope with straw insulation plates was compared to conventional recycled wall filling materials such as hollow wood fiber brick and Cellular concrete r through simulations of the energy consumption of an existing residential building in Bechar. They were generated by keeping the thickness of the climate wall and U-value constant. the results show that straw has a better result, reducing energy consumption and maintaining comfort. Straw insulated plates reduced heating and cooling needs in the home. They increased by 25% and 16%, respectively. Their energy efficiency was higher than the performance of other materials even if the walls in the scenario have the same U-value as Straw walls in current and future weather conditions.
