Abstract— Water features that are found in the urban zone influence the micro-climate atmosphere of the encompassing regions positively when natural cooling from the evaporative process is required during the hot radiant day. Consequently, this paper is focused on the influence of the wider water body on air, surface and physiological equivalent temperature at multiple scenarios at a pedestrian level. Where scenarios are based on the different materials being used to construct the footpaths and different width of water body of Malacca town. The climate data includes air temperature (Ta), relative humidity (RH) and wind velocity (v), globe temperature (Tg) and surface temperature (Ts) which were all continuously measured within the Malacca water body area at different scenario via field investigation through the instrument. The RayMan software package was used to elucidate the physiological equivalent temperature (PET) of the six scenarios. The results confirmed the bare red clay pavement materials that are close to adequately wide water body is the best scenario for maintaining low air and surface temperature as well slightly warmer comfort range at the pedestrian levels for creating suitable physiological equivalent temperature. This measurement activity seeks to provide an understanding in the field of climatic urban design, and the potential of utilizing water bodies (water cooling effects), as an urban design tool, about minimize the profound effects of extreme air and surface temperature on human comfort levels (PET) under the hot and humid condition in Malacca Town.

Index Terms— Pavement material, surface temperature, waterbody, physiological equivalent temperature (PET), Malacca town.
