Abstract
Global warming has become a major challenge of the present century, manifesting in temperature fluctuations and changes in precipitation patterns. Economic growth in urban areas attracts large populations, increasing the demand for housing, energy, water, and food, which in turn leads to various consequences such as higher building and population density, land degradation, and the destruction of natural and agricultural lands. The expansion of industrial factories and air pollution has recently caused significant climatic anomalies in Khorramabad. The accelerating trend of physical development, particularly in the southern regions of the city, further reflects these climatic challenges. According to meteorological data, the average temperature in the city has risen by 0.5°C over the past 30 years. Based on scenarios presented by the Intergovernmental Panel on Climate Change (IPCC), if this trend persists, temperatures could increase by up to 4°C. This study evaluates the relationship between climate change and urban space formation by simulating climatic data and urban environments at the neighborhood scale using the ENVI-MET software. The study analyzes three ten-year development phases (2007, 2012, 2017) by examining temperature, wind speed, and humidity. The findings indicate that semi-open spaces, moderate-density structures, and semi-compact urban fabrics represent the most effective urban forms for mitigating climate change impacts. This structural approach aligns with environmental design principles tailored to the specific climatic conditions of the study area and the prevailing climate change trends.
