Thermal performance of clay-straw wall incorporating phase change materials in Errachidia city (South Eastern Morocco): A simulation approach

The objective of this new study is to integrate a Phase Change Material (PCM) in a clay-straw wall to reduce the energy consumption of buildings in Saharan regions (Presented by the city of Errachidia in Morocco). The underlying idea is to fully exploit the storage capacity of walls built with clay...
