The environmental conditions of the outdoor space are closely related to the indoor space. Outdoor uncomfortable environmental conditions affect the indoor environment. To improve this situation, highly reflective material is one of the solutions to protect our citys thermal environment. It is expected to improve the outdoor space environment to make the indoor space more comfortable. This study is to analyze the numerical simulation of airflow and thermal environment for a factory campus when using various scenarios of highly reflective material. The results show that the highly reflective pavement can reduce the temperature of the painted surface by 10 to 15 ° C, and be reduced about 0.5 ° C at height of 1.5 m. For indoor space, the highly reflective pavement applied to the building outside surface can reduce the surface temperature, reduce the air temperature and reduce the indoor radiation temperature, which can make the indoor environment more comfortable, and reduce the urban heat island effect and building energy consumption.
