Increasing awareness of the urban heat island (UHI) effect has raised attention about the thermal comfort in cities worldwide. Several studies in the last decades have revealed how critical the UHI effect can be in a cold climate, Mediterranean climate. As a result, there is a need of study for composite climate like Delhi to reduce heat islands in urban areas. A lot of research on mitigation strategy has been done, but most of them considered with one or two variables like mostly are green, blue landscape and widely use of remote sensing data, LCZ -LST relationship. To the best of our knowledge no study has been carried out on the Integrated mitigation approach in composite climate. This study evaluates different UHI mitigation strategies in high rise residential area of Delhi selected according to their building density (LCZ Classification). The effects of cool surfaces (on the roofs, on the facade or as vegetation areas) are evaluated through numerical simulations using the software ENVI-met. Having obtained the surface temperature, potential air temperature, mean radiant temperature, and wind speed, this study compares the mitigation strategies for urban heat island effect and make conclusions about the most effective mitigation strategy.
