What is Innovative PCM-incorporated foamed concrete panels for walls’ exterior cladding: An experimental assessment in real-weather conditions about?

This study aims to develop innovative exterior cladding panels capable of improving the walls’ thermal performance for new and existing buildings. A phase change material (PCM) was incorporated into foamed concrete (FC) to develop innovative PCM-incorporated FC (PCM-FC) cladding panels, which were assessed as an exterior finishing of cement brick wall and compared to the conventional cement rendering. The test was conducted using reduced-scale testing cells in real-weather conditions and for four cardinal orientations. The developed PCM-FC cladding panels yielded remarkable reductions in the wall’s internal surface temperature and the cell’s internal air temperature, reaching 6.75 °C and 5.50 °C, respectively. Moreover, the developed cladding panels performed effectively for the four cardinal orientations, yet their effectiveness varied according to the intensity and the time of receiving direct solar radiation. Furthermore, a low decrement factor of 0.49 and a 32.1% reduction in the intensity of overheating were obtained when using PCM-FC cladding panels compared to Ref-CR. The developed PCM-FC cladding panels substantiated superior thermal performance in reducing external heat ga
