Aiming at offering reference for architects, urban planners and further research work in the sustainable building field, this work took the city of Guangzhou, China, as an example, by carrying out a 2-day constant field experiment in the campus of South China University of Technology, study on the influence of materials on the outdoor ground surface temperature, including concrete, pavement brick and grass. The result showed that, the grass surface temperature has the lowest temperature in both of daytime and night time, and it has no time delay compared with concrete and pavement brick ground, which should be due to the specific heat capacity of human built materials. The pavement brick has the highest surface temperature in daytime, but at late night time, it becomes lower than that of concrete ground, and this should be because that the specific heat capacity of pavement brick is lower compared with that of concrete. The surface temperature of concrete ground at night time is influenced by exposed time in daytime due to the influence of specific heat capacity, and in this experiment, the shaded concrete is lower than that of part-time exposed concrete ground at night time, and the part-time exposed concrete is lower than the concrete exposed all day, indicating that the ground material should be carefully designed in outdoor, taking both of thermal environment in daytime and night time into consideration.
