Abstract

The consequences of extreme energy consumption are seen both in the energy and environmental crisis. Subsequently, researchers are attempting to find methods to address this issue. Building envelopes and insulation materials are elements that can effectively influence consumption through their passive effect on thermal comfort levels. Strategies pertaining to this that rely on both, advanced and traditional materials, have been able to show good potential. However, the technical complexity of using such strategies can be impeded from the perspective of developing countries. With the aim of creating effective low-cost feasible insulations through using methods of minimal intricacies, the potentials of simple amalgamation of materials is empirically investigated in this study. In this context, closed-cell rigid Polyurethane (PU) foam is used as a base to hold phase change materials (PCMs) to create two PU/PCM panels, of different PCM content. The thermal performance of the panels is experimentally examined and compared, with hot-arid climates prevailing in developing countries in mind. Results revealed that panels containing PCMs were able to perform more effectively in comparison with regular PU foam panels, and, that increasing the amount of PCM has also shown to be advantageous in this regard.
