Study On Sports Training Stadiums With Green Roof Of Guangdong Pharmaceutical University Based On Thermal Acceptability

With the further development of the national fitness exercise,the sports training hall as its important carrier must not only meet the requirements of green and energy saving,but also require the creation of a good indoor sports thermal environment and acceptance.The soilcovered green roof,a well-known energy-saving design method at home and abroad,is of great significance in optimizing the urban landscape system,reducing building energy consumption and creating a comfortable indoor thermal environment,so it is also widely used in most public buildings.However,the research on the green roofs of sports buildings is mainly focused on energy saving,and there are relatively few studies on thermal comfort.Therefore,combining the green roofs of sports buildings and the thermal acceptability of sports population,explore the thermal acceptability of the people under different exercise intensity in sports training halls with the soil-covered green roof will be the focus of this article.In response to the above problems,based on the climate characteristics of Guangzhou,this article selects the sports training hall of Guangdong Pharmaceutical University with green roof as the research object,recruits suitable subjects to conduct actual measurement studies of different exercise intensities in the transition season,and adopts the operating temperature as the evaluation standard of the indoor thermal environment,analyze the thermal environment parameter data obtained in the two venues and the subjective evaluation questionnaires of sports population in different exercise states,and further process it to conclude the thermal neutral temperature and thermally acceptable temperature range of different exercise intensity under the green roof pavilion and the metal roof pavilion.In the transition season,the thermally acceptable operating temperature range of the sports training hall with green roof is 19.60℃-30.02℃ in the sitting state,17.52℃-28.60℃ in the shooting state,20.32℃-25.92℃ in the layup state,the upper limit of acceptable operating temperature for turn-back running state is23.37℃;The thermally acceptable operating temperature range of the gymnasium with a metal roof is 19.97℃-29.24℃in the sitting state,17.60℃-27.23℃in the shooting state,19.11℃-25.14℃in the layup state,the upper limit of acceptable operating temperature for turn-back running state is 22.66℃.By comparing the thermal environment parameters in the two venues and the upper limit of thermally acceptable temperature for sports population under different exercise intensities,as well as the indoor operating temperature and thermally acceptable temperature upper limit of the two venues on a typical day,the analysis shows that the sports training hall with green roof the indoor thermal environment and the upper limit of the thermal acceptable temperature have certain advantages,and the indoor thermal environment acceptance is better than that of a gymnasium with a metal roof.At the same time,it is also found that the sports training hall with green roof under the current situation is insufficient in cooling and heat dissipation at night and indoor ventilation,and the initial temperature during the day is higher than that of the metal roofing hall.Therefore,simulation methods are used to propose and summarize the optimization design method for ventilation and cooling for the sports training hall with green roof based on the actual situation.It also analyzes and summarizes the structural and construction adaptability between the green roof and the sports training hall.
