Green Building in New Era —Air dome building

The air-film building system integrates the inflation of the building, indoor ventilation and air conditioning, does not need to set up another internal pipeline, not only effectively saves energy, but also can set the ventilation times of 8-26 times per hour according to the number of people in the building to ensure the absolute freshness of the air in the stadium, and the excellent ventilation effect of the air-film building system enables athletes to be as comfortable and comfortable as outdoors when exercising indoors. Moreover, the appearance of the air film building is novel and beautiful.

The principle of air film building is to fix the membrane material on the periphery of the ground foundation structure. After the indoor air pressure is raised to a certain pressure by the air supply system, the pressure difference between the inside and outside of the roof is generated to resist the external force. As the membrane material is supported by the air pressure, there is no need for any beam or column, so a larger building space with complete clearance can be obtained. After more than 60 years of development, a set of complete theoretical system and technical standards have been formed for long-span gas film buildings.

The air film building is a closed large-span headroom structure with a maximum span of 180 meters and an unlimited length. The cost of membrane material is low, and the weight of roof is only 1/30 of that of conventional steel roof, thus reducing the cost of wall and foundation. The membrane body is simple and quick to install, can be used as temporary or seasonal buildings, and can be connected with other conventional structural buildings. There is no construction waste output during the manufacturing and construction of the membrane body. 

Film used in air film construction is a kind of film material with high strength and good flexibility, and its service life is more than 20 years. Its supporting systems mainly include: foundation anchoring and connecting system, standby power supply, refrigeration and heating system, lighting system, entrance guard system, fresh air conditioning system, intelligent control system, etc.
