Discharging of the PCM can be seen when the temperature of the room is at a minimum thereby enhancing the thermal comfort. The PCM walls were found to enhance thermal cooling as they were at a lower temperature than without PCM. It was reported the 5 mm of PCM wallboard had twice the available energy storage as that of an 8 cm concrete layer.
