The increase of Urban Heat Island (UHI) intensity in big cities has become a real challenge for the urban climate adaptation agenda. Modification of urban microclimates in residential areas certainly contributes to this issue. This study stresses the concept of Climatically Responsive Urban Configuration (CRUC) to propose sustainable urban configurations tropical cities. The study emphasizes that Oke's empirical model on the heat energy in urban canyon space plays a significant role in defining the research gaps in CRUC concept. It simulated hourly air temperature by using Oke's model and ENVI-met simulation in four urban configurations of residential areas in Kuala Lumpur. The results of both methods validate the trend of high air temperature in residential areas were caused by the reduction of Sky View Factor (SVF) value. However, the results strongly point out that Oke's model as the pioneer approach in urban heat energy does not just apply in urban canyon but also in other types of urban configuration. The findings suggested recommendations of CRUC to meet the climate adaptation agenda.
