Abstract

Urban configuration modification is an efficient approach to mitigating Urban Heat Island effect. This study investigates the significant impact of solar radiation and urban wind on microclimate and thermal comfort in the different setting of urban canyon configuration. The Envi-met (V3.1 beta) simulation presents that East-West canyon direction received the worst level of air temperature and meant radiant temperature compared to when the canyon was directed perpendiculars to the wind direction (South East – North West). The finding scientifically demonstrates that in Kuala Lumpur context, with the slow urban wind speed influences, solar radiation plays the significant impact on the microclimate.
