China Pavilion
Most areas of the pavilion are placed under the terraces, which reduces the heating and cooling energy consumption of the buildings. The roof is equipped with a rainwater collecting system. The recycled rainwater will be used for terraced irrigation to form an ecological microcirculation. The steel structure roof of the China Pavilion is equipped with 1,024 photovoltaic glass, which has higher light energy absorption efficiency and can better adapt to the shape trend of the building.
