Numerical analysis of PCM integrated year-round thermal energy savings building for composite climatic conditions

Abstract Incorporating PCM in building envelopes is a promising energy-saving technique. Because the PCM container maintains a constant temperature when storing and retrieving energy. The PCM is used in building envelopes to diminish solar irradiation, reducing heat penetration and lowering heating and cooling loads. It’s vital to get the right PCM for different climates. Because the ambient air temperature fluctuated a lot throughout the year. PCM temperature effectiveness is highly determined by local ambient weather conditions. It is challenging to design the PCM integrated building for year-round thermal regulation. This research discussing PCM’s thermal energy effectiveness in building walls for decreasing interior temperature variance in composite climatic systems using numerical simulation using EnergyPlus software.
