The role of surface temperature is rarely been studied when it comes to thermal comfort issues. This paper aims to identify the effect of the surface temperature of vertical entities of built masses on thermal comfort parameters. The existing neighbourhood at NOIDA, Delhi NCR with varying morphological character and variation in heights and orientations was selected. The results showed that Surface temperature did not affect greatly to PET, whereas the effect on Tmrt was significant for most of the scenarios. The relationships with the east-facing surfaces could be observed whereas due to the longer exposure to direct solar radiation, the relationship with S, SW, SE surfaces is moderate. A negative effect on thermal comfort was observed as the height of the vertical surface increased. The study will help improve the understanding of the morphological configuration to reduce the surface temperature and eventually in achieving a better thermal comfort level.
