Abstract

Concrete exhibits low thermal conductivity due to its inherent material properties, enabling it to trap and retain heat for extended periods. Its high thermal mass and moderate specific heat capacity slow heat release, creating cooling challenges, particularly in urban areas of Bangladesh during summer. Inefficient HVAC systems exacerbate these issues, reducing thermal comfort and energy efficiency. Temperature regulation is especially crucial in residential, commercial, industrial, healthcare, and recreational buildings, as well as specialized facilities such as greenhouses, cold storage, and military shelters. Phase Change Materials (PCMs) offer a sustainable solution for passive thermal regulation by reducing reliance on active systems, stabilizing indoor temperature fluctuations, and lowering energy use. PCMs possess high energy storage density, are reusable, and help minimize operational costs. Numerical analysis of PCM integration within building envelopes reveals significant improvements in thermal performance and helps mitigate carbon emissions linked to the greenhouse effect. During phase transitions, PCMs absorb heat and reduce heat transfer; about 50% of the melting process occurs within 1.6 h and completes in seven hours. Entropy rises during melting, reaching more than three times its initial value at the building’s tip. These findings emphasize PCM’s potential to enhance energy efficiency and thermal comfort in modern construction. Further studies are needed to optimize PCM placement based on building geometry and local climatic conditions to maximize performance. PCM integration supports sustainable architectural practices and aligns with green building standards.
