Abstract: This study highlights the ongoing search for sustainable and thermally suitable phase-change materials (PCMs), for hot weather building climates, such as Iraq. This new PCM must have an extraordinary heat and cold retention ability. Building industries are interested in using paraffin’s in their roofing materials, because of their thermo-physical properties, their profitability to save on electricity and HVAC (heating-ventilating air conditioning) systems, their local abundance, as well as their environmentally friendly nature. In this study, three PCM compositions were prepared, each with varying oil to wax ratios, using fractionation, de-waxing and crystallization. Preliminary research conducted in Bagdad shows tremendous savings in electricity usages, as well as lowered internal temperature fluctuations.
