Another interesting technological solution is adopted in the roof of Chinese pavilion. The structure of the roof is composed of laminated wood beams joined with steel elements. A complex
work has been made to design a roof so big and six steel beams were added to increase the
construction stiffness. Furthermore the roof is covered by a layout made of translucent textile
membranes and bamboo panels. The texture of this layout is designed to make the day-light pass
ensuring a cool environment in the hottest days. The shape of the building has been designed to
permit the reinstallation of the pavilion in an already chosen site in China. Due to the materials
and the techniques employed in the building, China pavilion is one of the most interesting architectural and engineering attractions of the exhibition.
Even Russian designers worried about the re-installation of the pavilion in their nation. In fact the
most impressive element of the pavilion is surely the 30 meter long cantilever, which is a metaphor referencing the soft lines of the Russian landscape. Russia also tried to respect all the way
the sustainability guidelines, improving a structure of steel beams covered by different types of
wood. Wood is the principal cladding element: floor and insulation elements are of wood and the
façade is in Oak Lamella.
Bamboo represents an interesting new cladding solution. As already mentioned Chinese designers adopted bamboo panels for the roof, but also Indonesian pavilion is made with a massive use
of this material. The most interestin
