“…Among the methods employed to improve building envelopes, using phase change materials (PCMs) is an effective method of enhancing thermal storage capacities of buildings. Several researchers have investigated this method in different forms [3][4][5][6][7][8][9]. These studies have concentrated on impregnating PCMs into materials like gypsum wall boards, plasters, textured finishes, as well as PCM trombe walls, PCM shutters, PCM building blocks, air-based heating systems, floor heating systems, suspended ceiling boards, etc.…”
