Development and evaluation of a retractable phase change material (PCM) roof for thermal comfort in tropical buildings

This research focuses on the development and evaluation of a retractable Phase Change Material (PCM) roof designed to regulate indoor air temperatures in tropical building conditions. The innovation combines PCM, which absorbs and releases thermal energy to stabilize temperatures, with a retractable mechanism that adapts to varying weather conditions. By using simulation software, the study explores the roof's thermal performance, the influence of PCM properties and operational settings, and its potential to improve thermal comfort compared to conventional roofing systems. The retractable PCM roof offers several advantages, including enhanced thermal regulation, energy efficiency, and dynamic adaptability, making it uniquely suited for tropical climates. Its dual functionality addresses challenges posed by high temperatures and humidity while reducing dependency on mechanical cooling systems. The system contributes to environmental sustainability by lowering energy consumption and carbon emissions, aligning with global green building goals. This innovation holds significant commercialization potential, with applications in residential, commercial, and institutional buildings. It caters to markets in tropical and subtropical regions where passive cooling solutions are in high demand. By improving occupant comfort and supporting energy-efficient building design, the retractable PCM roof delivers socio-economic and environmental benefits, presenting a scalable and sustainable solution for the construction industry
