This study investigates the impact of Phase Change Material (PCM) placement on energy conservation in a detached house, specifically focusing on outer walls (separately), flat roofs, and all outer wall applications. The research involves thermal analyses considering differnt melting temperatures and PCM layer thicknesses using EnergyPlus building simulation software. The optimal melting temperature for PCM placement is determined to be 25 °C for north, south, and east-facing walls, while it is 27 °C for west-facing walls. Interestingly, the orientation of the outer wall does not significantly affect the melting temperature selection. Furthermore, PCM25 is found to be the optimal choice for flat roof application as well. The results highlight the importance of selecting the right melting temperature. For instance, at a 20 mm PCM layer thickness, PCM25 yields an impressive energy saving of 397.8 kWh, while PCM21 only conserves 190.9 kWh. Thus, the choice of PCM21 is shown to be the least effective for energy conservation. Comparing different PCM placements, it is observed that PCM placement on flat walls (FW) provides the highest energy savings of 432.6 kWh, while all wall placement (AW) still offers a substantial energy conservation of 397.8 kWh. These findings underscore the potential of PCM placement strategies in enhancing energy efficiency in detached houses.
