The integration of phase-change materials (PCMs) into building commodities is a favorable technology for minimizing energy consumption and enhancing thermal performance. This review paper covers the impact of PCM incorporation into construction materials, such as walls, roofs, and glazing units. Additionally, it examines different embedding techniques like direct incorporation, immersion, macro and micro-encapsulation, and form and shape-stable PCM. Factors affecting the thermal performance of PCM-integrated buildings, including melting temperature, thickness, position, volumetric change, vapor pressure, density, optical properties, latent heat, thermal conductivity, chemical stability, and climate conditions, are elaborated. Furthermore, the latest experimental and numerical simulations, as well as modeling techniques, evident from case studies, are investigated. Ultimately, the advantages of PCM integration, including energy savings, peak load reduction, improvement in interior comfort, and reduced heating, ventilation, and air-conditioning dependence, are explained alongside the limitations. Finally, the recent progress and future potential of PCM-integrated construction materials are discussed, focusing on innovations in this field, addressing the status of policies in line with the United Nations Sustainable Development Goals, and outlining research potential for the future.}, year = {2025}, eissn = {2075-5309}, orcid-numbers = {Rahman, Ihsan Ur/0000-0002-7062-1529; Manca, Oronzio/0000-0001-7226-3537; Buonomo, Bernardo/0000-0003-1279-6934; Caggiano, Antonio/0000-0003-1027-2520; Nardini, Sergio/0000-0003-3000-8444} } @article{MTMT:36202250, title = {Combining aesthetics and efficiency: PCM applications in Flemish bond walls}, url = {https://m2.mtmt.hu/api/publication/36202250}, author = {Saliby, Ammar and Kovács, Béla}, doi = {10.1556/606.2025.01346}, journal-iso = {POLLACK PERIODICA}, journal = {POLLACK PERIODICA: AN INTERNATIONAL JOURNAL FOR ENGINEERING AND INFORMATION SCIENCES}, volume = {20}, unique-id = {36202250}, issn = {1788-1994}, abstract = {Increasing energy demand in buildings requires efficient strategies.
