Abstract

Outdoor thermal environment in urban spaces is important for people to enjoy the urban environment. This paper investigated the effect of urban design on outdoor thermal environment in an urban street in the central business district in Singapore, focusing on street orientation and height-to-width ratio. The microclimatic parameters of different street design scenarios were determined by ENVI-met numerical simulation. Field measurement was conducted to validate the results from the numerical simulation and they were in good agreement. For different design scenarios, it is found that (1) The air temperature differences did not exceed 0.8°C; (2) The mean radiant temperature differences could e..
