Thermal impact study of a bio-based wall coupled with an inner PCM layer

Our study focuses on the thermal performance evaluation of a solar room built using a new bio-based composite wall coupled with a phase change material (PCM) layer during the cooling season in Nancy city France. This composite wall consists of a bio-based panel IBS-IZOLOX developed by the Belgium company ISOLHABITAT. The inner side of this bio-based composite wall should be coupled with a PCM layer in order to improve the thermal inertia of the room envelope. The results show that this system wall can improve significantly the thermal comfort performance of the passive solar room during the cooling season.
