A growing majority of 55% global population now resides in urban areas, a proportion that is expected to increase to 68% by 2050. One of the consequences of such an increase in urban development may be the empirically observed phenomenon of the Urban Heat Island (UHI) effect. This paper presents the analysis of microclimatic conditions in urban street canyons in a city location Vishrantwadi, Pune, India. A number of field measurements were carried out during summer 2017 aiming at the investigation of the microclimate parameters that affect thermal conditions in the city’s streets. The objective of this paper is to investigate the effect of vegetation on UHI mitigation in Vishrantwadi based on field measurements through IR Gun on an area consisted by several building blocks carried out in adjacent greenery and non-greenery spaces during summer time. The recommendation of this study will help Architects and Urban planners to find the manual to know how to use vegetation to mitigate the Urban Heat Island Effect.
