This book explores experimental and numerical research findings from the literature, aimed at evaluating and improving the livability of temporary housing solutions. Building upon these insights, a comprehensive workflow for assessing and refining indoor comfort is presented, illustrated through a detailed case study conducted by the authors. This methodology serves as a guide for researchers and practitioners tackling similar challenges in the field. First, the book summarizes the architectural characteristics and design requirements of temporary housing, focusing on how these factors influence the indoor thermal environment. Next, it provides a thorough literature review on thermal comfort studies within temporary housing contexts and offers a unified and coherent framework for evaluating and enhancing thermal comfort. The book equips architects, engineers, researchers, and humanitarian professionals with the knowledge and tools needed to design sustainable and comfortable modular solutions for refugee housing and other temporary structures worldwide. It stands as a unique guide for those committed to creating dignified, livable spaces for displaced populations, and advancing the state of the art in emergency architecture.
