Solar energy utilization for covering the heating loads of buildings is an innovative and clean way to reduce electricity consumption. A Trombe wall is a classical passive solar heating system used in buildings. Increasing the weights and volumes of Trombe walls can increase their heat storage capacities. However, this process increases a building's dead load, which is considered a problem by structural engineers. Among the alternatives for solving this problem is to use phase change materials (PCMs) for higher heat storage. This work presents a comprehensive review on the different advantages of integrating PCMs with Trombe walls. The article shows that the satisfactory heat storage capacity of PCMs can improve indoor air thermal circulation and decrease indoor air temperature fluctuations. In addition, the effectiveness of PCMs in providing protection from overheating, and improving the efficiency of the energy management process and energy saving of Trombe walls is demonstrated.

The parietodynamic wall, a type of dynamic insulation, has been recognized as an effective technology to reduce energy loss in buildings by recovering heat energy through forced convection. However, current research on the thermal performance of parietodynamic walls has overlooked the influence of thermal radiation, a crucial factor in energy transfer within the air layers of these walls. To bridge this gap, an innovative simulation model was developed and experimentally validated. Employing simulation methods, we investigated the impact of thermal radiation on the thermal behavior of parietodynamic walls under various influencing factors. Our findings reveal that thermal radiation markedly increases heat loss. Specifically, at an emissivity of 1, thermal radiation contributes up to 80.7% to the heat transfer coefficient (HTC) of the parietodynamic wall. Moreover, for a parietodynamic wall without insulation, the HTC of this wall will increase by more than 268% when thermal radiation is taken into account, compared to when it is not considered. These revelations deepen our comprehension of the role of thermal radiation in parietodynamic walls and offer valuable guidance for the development of more energy-efficient buildings.
