Thermal performance of a novel building wall incorporating a dynamic phase change material layer for efficient utilization of passive solar energy

A new type of wall for building envelope is studied and its performance is analyzed in detail using computational fluid dynamics. The wall is designed to absorb and store passive solar energy during the day in winter and release it to the inside of the building at night. The salient feature of the wall is the presence of a phase change material (PCM) layer within the wall and its ability to switch its position with the insulation layer within …
