The most specific advantages of this project is Environmental- friend. Green energy conservation is a comprehensive challenge in large-scale terminal building.Because the front facade of the main building is very long, if the height of the main building is simply lowered to reduce the volume of the interior to reduce energy consumption, the proportion of the building will be out of balance, unable to reflect the role of the city portal sign.On the other hand, several of the largest airports in China have adopted high curved roofs in the middle in order to reflect the grandeur of the city gateway, but they are high and useless in function, and on the contrary, they greatly increase the energy consumption of the interior space.
