Abstract

The roof design is a critical part of the design of large-space stadium. With the increasing requirement of sports environment, a good design of stadium roof not only with reasonable structure but also has the function of improving the sports thermal environment of stadium and improving the sports thermal comfort of the exerciser. Through the research of sports thermal comfort under the large-space green roof in the specific climatic conditions, this study primary got the relationship between the sports thermal comfort in the stadium and the thickness of cover soil & the plant disposition of green roof. It not only provides a theoretical basis for creating a healthy sports environment under the green roof, but also provides a theoretical foundation for upgrading the existing sports environment. Firstly, this study use software to simulate 2 stadiums in Guangzhou in Summer. One stadium with exposed roof and the other one with cover soil green roof. Then a preliminary study of the relationship between 2 roof design strategies and thermal environment of stadium be made through data arrangement and analysis. Secondly, several stadium models in Guangzhou area of China be simulated in software, each one with the same roof structure and with the different parameters of cover soils, such as the thickness of cover soil and the plant disposition. And then, basing on the SETsport （Standard Effective Temperature under the state of sports）which gained through modifying the calculation parameters of SET（Standard Effective Temperature), the stadium models with good sports thermal environment be selected.Finally, through analyzing the data of the stadium models with good sports thermal environment, this study got the correlation rules between parameters of cover soils and indoor sports thermal environment & sports thermal comfort.
