Abstract

As regions that are close to the equator, urban landscapes of hot-humid tropics are often exposed to the high intensity of solar radiation. The increasing heat gain and reduced evaporation in tropical outdoor environment has resulted to the overheating of urban areas, thus contributing to the outdoor thermal discomfort. The aim of this study is to investigate the effect of morphological aspect on the microclimatic condition in location of various urban landscapes morphology in Putrajaya. Field measurements were conducted to obtain temperature, relative humidity and wind speed variations at various urban spaces. Results showed that microclimatic condition exhibited variations in different urban landscapes. The findings indicated that the urban landscape morphology strongly influenced microclimatic conditions in the study area. The outcome of the study is hoped to contribute towards better understanding on the interrelationship of urban landscape variables and its implication to the outdoor environment in hot-humid climate. The applied understanding on the influence of landscape and urban morphology could provide detailed information to planners and architects especially in determining the design aspects that helps to promote outdoor thermal comfort in hot-humid environment. Keywords: hot-humid city, microclimatic condition, outdoor thermal comfort, landscape design approaches.
