Shanghai Chilean Pavilion

CHILEAN PAVILION WORLD EXPO SHANGHAI 2010 In account of the Expo’s theme “Better city, better life`, the proposal of the Chilean Pavilion is to focus in the recovering of mankind and its relations as the main subject of reflection and as the main condition for life in cities. The arquitecture is constructed around a spatial proposal for the apropriate exhibit of its contents, as much as solving the requirements of representation, of program and pavillion operation. The building proposed, a translucent organic 2.500 m2 volume, that in one single big space takes in the different rooms and premises that the program requires, considers the ephemeral character of a massive event adressed to the common inhabitant of the city in a context of thousands of pavilions. The sorrounding translucent facade stands out unveiling an inner public space over wich converge and defferenciate the different bodies of the programatic rooms. Each one of these fullfils a role in the constitution of the proposed recount that expresses itself through a trajectory of wood ramps as if it was an urban street that will take visitors to the different theme rooms. The most imprtant one is what we call “The Seed`, were the essential of the proposal is revealed: the vision of the city as a place of human relations more than one of builings, streets and networks. The journey culminates in a main square that comprises the entire space of the pavilion and from were one can participate of all the activities and contents. At the same time, the square contains the cafeteria, shop, exhibit spaces and social and cultural events areas that for six months will be part of the presentacion. The building materials respond to facilitate both conditions of a construction with a limited time frame and a functional response to programatic atmosphere and image needs. As a design premise, all the elements that compose the building, except foundations, can be dismantled and the majority of the materials and equipment can be recycled or reused. The bearing enclosure structure of pilars and beams and the roof truss’, all of them of bolted steel, favour the assembly and later dismantling of the building as much as a light, playful and translucent proposal. The translucent facade, a recycled glass protected from the sun by a steel mesh allows to unveil the inner space and the entrance of natural light. The theme rooms, arranged through the length of the ramp trajectory, are necesarily opaque for light control, lined in the exterior with self rusting steel. For pavements, ceillings and linings Douglas Fir wood, renewable product found in Chilean plantations, has been proposed in it’s different marketing forms, plywood, laminated and singular wood elements. Laminated fir wood sheets are used as pavement on circulation ramps and as lining for “The Seed`. At the same time, plywood sheets are used in lining and flooring of theme rooms and those of supporting program such as meeting rooms, exhibits and others. In the main square, a suspended steel and wood brise soleil ondulated ceiling along with the pavement that contemplates level differences produced by distinct lines of plywood sheets cut as level ground curves propose different atmospheres that favour meeting instances that the pavillion theme is looking for, allowing the realization of different programed activities as at the same time merges with them. Besides the reusable condition of the building above mentioned, in order to obtain the maximum comfort and to respond to strict norms of energy saving and control, placed by the organizing comitee that established a maximum consumption of Kw/hr., and as well as maximizing the intake of natural light through skylights and the translucent steel mesh facade, an insulation system with recyclable products has been used in all opaque enclosures, and a green roof for temperature and radiation control has been incorporated to the design as well.
