Abstract	Urban streets in Indian cities are growing rapidly, which increases the heat stress, making microclimate-sensitive design essential. The Local Climate of the Street in an urban area can be greatly affected by the urban thermo -physical and geometric characteristics present in the urban street. The interest of micro climate has been raised as they represent important factors in achieving energy conservation and thermal comfort of the human beings inside the cities where the whole people resident in the cities. The paper examines how the landscape elements such as trees, shrubs, pavements and water body modify the microclimate in the selected urban streets. Four streets with various compositions of the trees, shrubs, pavements and water body has been deliberately chosen, each justified through various landscape characteristics. Based on the presence of Landscape elements in the streets, Landscape cover Index (LCI) was developed to do a comparative analysis to find the influence of these landscape elements across the selected streets. A particular day was selected and field measurements were conducted on a climatically consistent day to record air temperature, relative humidity, wind speed, and surface temperatures. Additionally secondary climatic data, including the day’s maximum and minimum temperatures, were sourced online for validation. Envi-met Stimulations were also take on the same day to provide spatial microclimate predictions, which were compared with field measurements to assess reliability and highlight correlations. Finding show that streets with high landscape cover index especially which has dense canopy measurements and water body nearby exhibit lower air and high relative humidity levels. The comparison between field data and Envi-met outputs confirmed consistent trends. Overall, the study demonstrates that strategically planned landscape elements can meaningfully improve thermal comfort and microclimate performance in urban streets, reinforcing the role of landscape architecture in climate-responsive urban design.
