Reutilization of thermal energy according to building demands constitutes an important step in a low carbon/green campaign. Phase change materials (PCMs) can address these problems related to the energy and environment through thermal energy storage (TES), where they can considerably enhance energy efficiency and sustainability. Concrete researches focusing on building materials revealed a vast potential of inorganic PCMs (iPCMs) utilization in thermal energy management systems particularly in the building applications as per literature; however, large but scattered literature is available on this research dimension. The current study presents an up-to-date review on iPCMs in the context of latent TES in the building sector: summarizing its performance, applications, and key challenges. The thermal performance of iPCMs is based on the higher heat storage capacity per unit volume together with lower …
