Challenges and Countermeasures for Thermal Environment and Indoor Air Quality in Sports Buildings

the sports building is often crowded with many sports practitioners, so the thermal environment and indoor air quality in the sports buildings are very important to the athletes and other sports practitioners. Many problems such as different demands between auditorium and playing area, air conditioning system design and air conditioning operation exist in sports buildings in order to improve the thermal environment and indoor air quality. In view of the problems, it's proposed to compare the air distributions of different working conditions for optimal flow pattern, consider the usual requirement and competition requirement in calculating the air conditioning load and explore the testing and evaluation technology of thermal environment and indoor air quality. The general suggestions will provide references to the guarantee of the thermal environment, indoor air quality and energy efficiency in sports buildings.
