Rapid urbanization presents significant challenges, especially in developing countries like India. The literature review highlights the decline in thermal comfort levels in urban areas and the impact of inefficient design on this issue. To tackle these challenges, this paper proposes using simulation modeling as a tool to visualize and mitigate urban heat island effects. The study employs a case study approach to collect microclimatic data and neighborhood details. By comparing field data with simulation results, the validity and reliability of the simulation modeling are established. Statistical tests including correlation coefficient, coefficient of determination, root mean square error, mean absolute error, mean bias error, and index of agreement were conducted to verify the measured and modeled data. The analysis demonstrates that the measured and modeled results align, indicating the simulation model’s potential for predictive scenario analysis. As a key contribution, simulation modeling, particularly through software like ENVI-met, empowers architects, urban planners, and government bodies to simulate microclimatic variables and explore various urban design scenarios for the case study area. Ultimately, this paper emphasizes the importance of integrating simulation modeling with field measurement data to strategically plan building layouts and vegetation strategies, thereby mitigating the adverse impacts of urbanization on both the environment and human well-being.
