Abstract

Abstract
Planning and designing cities that can effectively respond to climate change requires a thorough understanding of their physical characteristics across various spatial scales, from metropolitan to local urban blocks. This study aims to identify, classify, and analyze the physical indicators that influence climate adaptation and thermal comfort in urban areas. The research specifically focuses on the urban block scale, where four distinct urban blocks in the city of Meybod were selected as case studies. These blocks were chosen based on their varying physical characteristics, which were determined through an extensive review of relevant literature and expert analysis. To ensure accurate evaluation, the selected blocks were simulated and analyzed using Envi-met V5.5 software, which modeled microclimatic conditions, while Depthmap 10 software and the Shannon Entropy model were employed to assess the physical sub-indices. Additionally, considering the predicted climate conditions for the next fifty years (up to 1450 in the Persian calendar), the most comprehensive urban block design proposed in the detailed development plan of Meybod was also assessed for its climate responsiveness. The findings reveal a strong and significant relationship between physical characteristics—such as the orientation of passages toward prevailing winds, urban compactness, shading from buildings, and green space density—and improved thermal comfort. Moreover, the results indicate that urban blocks with higher interconnectedness, stronger connectivity, and lower spatial depth demonstrate superior adaptation to climate change. These findings suggest that urban planners should prioritize these physical characteristics to enhance climate resilience in future urban designs, especially in hot and arid regions like Meybod. This research provides a structured framework for understanding and applying physical indicators in urban design to improve resilience and thermal comfort in the face of climate change.
