Residential districts play important role in people living and outdoor activities. The purpose of this study was to evaluate outdoor thermal environment in summer based on different ground greening of apartment complex in Sino-Singapore Tianjin Eco-City residential area, located in Tianjin's Binhai New District. The project shows the determination of the two countries to respond to global climate change, strengthen environment protection, provide an active exploration and typical demonstrations for the construction of a resource-saving and environment-friendly society. Through analysing the first phrase of Eco-City residential area, Slab-South-North and South Stagger high-rise apartment complex, as a typical layout type, was chosen to set centralized ground greening, dispersal ground greening and mixed ground greening, simulated micro-climate environment by using ENVI-met(V4.4 Winter1819). The results of this study as follow: The average value of air temperature reached 37.5℃ in the dispersal ground greening scenario. And the mixed type and centralized type reached 37.6℃ and 37.7℃ at 15:00. The dispersal type's average value of mean radiant temperature reached 73.2℃ at 15:00 and reached 32.4℃ at 6:00, was the lowest value compared with the other scenarios. The same as air temperature and mean radiant temperature, the dispersal type has the lowest average value of PMV at 15:00. Dispersal ground greening's cooling effect is more effective Comparing with centralized and mixed ground greening scenarios in Tianjin's Binhai New District.
