As one of the world’s most rapidly urbanizing cities, Bangkok is experiencing the growing effects of climate change, particularly flooding and urban heat island effect. The need for integrated sustainable architectural solutions is critical for climate adaption to the city’s growing challenges. By revisiting traditional flood resilience and cooling practices in Bangkok’s vernacular buildings, this research will propose how these time-tested solutions can be integrated into modern architecture and urban planning to improve climate resilience, reduce health risks, and enhance the population’s well-being in the face of climate change. Bangkok is an ideal case study for this research due to its unique set of climate challenges and its culturally and environmentally influenced vernacular architecture. The research will be conducted by site visits to flood-prone neighborhoods, interviews with architects and urban planners, analyzing and collecting data in urban heat islands, case studies, and assessment of health impact. The research project will give opportunities for design analysis, reflection, and research in connections between design practices, materiality, climate resilience and health outcome.
