Abstract Building construction uses a lot of energy, thus it is important to pay attention to it with feasible solution. Phase Change Materials (PCMs) offer useful options for increasing thermal properties of building materials and energy efficiency. PCMs do, however, have certain drawbacks, including deteriorating mechanical qualities, raising expenses, chemical instability, and other issues. This study provides a thorough overview and discussion of the major properties of PCMs, design and incorporation techniques, effects on energy consumption, and construction reliability. While many materials possess the ability to undergo phase change, certain organic phase change materials (PCMs) are more suited for building environments because of their favorable phase change point and higher latent heat. Eutectic PCMs have the potential to be the best option, but further research is necessary to fully understand this phenomenon. The essential requirements can be addressed by current design methods and building material applications, but their effectiveness is insufficient due to low phase changing efficiency and low energy storage. Consequently, this report also suggests some important areas for optimization and intriguing future directions. Prospective advancements in PCM technology, such as innovative PCM and effective integration, are suggested, along with practical uses and roles in construction. Furthermore, multipurpose building materials that incorporate PCM are deserving of significant consideration and have a bright future in the construction of sustainable and energy-efficient buildings. © 2025 The Authors.
