In recent years, there has been an increase in conflicts, natural disasters, and migrant crises, necessitating the rapid deployment of temporary housing solutions. These shelters, while crucial for immediate relief, often provide poor indoor hygrothermal conditions, potentially causing health issues during prolonged occupancy. In this context, it is essential to investigating and improving their thermal environments. This book collects and presents the results of a series of experimental and numerical activities carried out by the authors to improve the livability of temporary housing solutions. The comprehensive workflow represents a guide for researchers and practitioners addressing the same issues in this field. The book is structured as follows. First, architectural characteristics and requirements of temporary housing solutions are briefly summarized and presented with a particular focus on the impact of these features on the thermal environment. Then, a scientific literature review of studies addressing thermal comfort in temporary housing is provided. Finally, the authors’ experimental and numerical activities are collected and presented. The findings are discussed and compared to other temporary solutions, offering a broader perspective on addressing the challenges of thermal comfort in emergency architectures.
