Cities frequently experience urban heat islands (UHIs), defined as regions where the urban environment is warmer than the rural surroundings. These characteristics are a direct result of urbanization, which eliminates natural vegetation and water sources and replaces them with impermeable surfaces with low albedo. Due to the urban heat island effect (UHI), cities are especially vulnerable to excessive heat events. The relationship between UHI and urban thermodynamics is explained by recent studies in the physical sciences, and these studies lay the groundwork for understanding how changes in the physical environment affect microclimates. The purpose of the study is to analyses the development of urban climate change as well as the technology used to mitigate it. Significant effort has been made in this particular time frame to comprehend and monitor urban climate change as well as to design and test alternative mitigation methods in high density residential areas of Delhi. The research The case of Delhi, India, using the microclimate modeling system ENVI-met, which models the temperature effects of various construction situations, has been analyzed in this paper. As a result, after applying all possible intervention, we conclude that in all other strategy temperature is increasing as comparison to base case so applying high emissivity paint on facade and green roof is the best strategy to mitigate high temperature in urban area.
