Description Technical file

Spain Pavilion. The pavilion of the host country. In contrast to the international exhibitions held abroad, Spain will be represented in Zaragoza by the different themed pavilions, the pavilion of the autonomous communities, the pavilion of Aragon, etc. Among all of them, it is the task of the Spain Pavilion to offer a global vision of our country. Together with exhibitions and activities, the facilities will house numerous institutional events, both on the National Days of the participating countries and on the Days of Honour of the autonomous communities, to which it will give special support.

Spain Pavilion. The pavilion of the host country
In contrast to the international exhibitions held abroad, Spain will be represented in Zaragoza by the different themed pavilions, the pavilion of the autonomous communities, the pavilion of Aragon, etc. Among all of them, it is the task of the Spain Pavilion to offer a global vision of our country. Together with exhibitions and activities, the facilities will house numerous institutional events, both on the National Days of the participating countries and on the Days of Honour of the autonomous communities, to which it will give special support.

Science and creativity
Under the motto of Science and creativity, the Spain Pavilion at the International Exhibition of Zaragoza 2008 has the mail goal of presenting a dynamic, modern, scientific and creative vision of Spain on the subject of water, its origins, its properties, its evolution, its uses, the way it is managed, its importance. Thus the Spanish pavilion will explain in an entertaining and spectacular way why water is today one of the central elements in the future of our country and of our planet.
Another of the objectives is to situate Spain in a worldwide scientific context and to present its contributions and future approaches to the problems and threats posed by climate change. The image of a supportive country is projected, committed to resolving environmental problems, with a strategic resolution to opt for renewable energies.
For these reasons, the exhibition content of the pavilion not only seeks to inform on the reality of water in its global context, but to actively involve the visitors, making them feel their responsibility in the everyday management of our water resources.
The building itself is a revolutionary answer to this approach, using water, ventilation, shade and the protection created by the roof and the multiple pillars that surround the glass boxes – in which the displays will be installed—to transform the pavilion into an example of ecological, sustainable architecture.

The building
The pavilion, the work of the Navarre architect Patxi Mangado with the collaboration of the National Centre for Renewable Energies (Cener) –a specialist in renewable energies and bioclimatic design—will be one of the most emblematic of Expo Zaragoza, both for its aesthetic and for the materials employed.
The pavilion is an example of an architecture that is committed to the environment and to sustainable development.
A forest of pillars that envelops diaphanous glass volumes where the exhibitions are held constitutes the base of the pavilion, conceived according to energy-saving criteria, with a great roof that shades the building. In this way, and through the use of environmentally friendly materials and the integration of renewable energies, the pavilion develops a microclimate that allows the visitors to take shelter from the intense heat of Zaragoza’s summer.
The multiple pillars, encased in fired clay, become the supports that generate this microclimate. The roof is a container of energy, with solar panels and water collectors to recover rainwater.
Perfectly insulated and laid out, the exhibition spaces are situated inside the forest to cover a total surface of over two thousand metres square of the approximately eight thousand that the pavilion distributes over three storeys.

Contents
The route through the pavilion is structured into five exhibition spaces. On the main floor are the rooms for A History of Water, Water on Earth, Spain and Water and Climate Change; on the semi-basement, a last space houses an exhibition on sustainable architecture and development.
In the first room, above a circular dome, an audiovisual is shown, A History of Water, on the appearance of water in the universe and the importance of its presence on our planet. Produced by Mediapro for the SEEI and directed by Manel Huerga (Salvador and Antártida) and Franc Aleu (La Fura dels Baus), it incorporates the latest technical advances in image and sound to take us on an extraordinary journey halfway between imagination and reality.
The room dedicated to Water on Earth (produced by Empty, as are the next ones) is based on the same premise: the amount of water on our planet has always been the same, according to the scientific adviser Juan Pérez Mercader, director of Madrid’s NASA-associated Astrobiology Centre. This room informs the public on the concepts related to the nature of water, its properties, the hydrological cycle of water or its role in the formation of the different ecosystems. A collection of gems, the largest in the world of precious stones and the property of the Royal Collections, closes the route through this room.
The section Spain and Water shows both the reality of water in our country: surface water (hydrographical basins, surface waters, magnitudes) and water that is not seen (subterranean waters and types of aquifers). The route closes by especially emphasising three fields in which our country maintains an active presence. Water and International Cooperation: projects on the water resources developed by the Spanish Agency for International Cooperation in both Africa (Azahar project) and in Latin America (Araucaria XXI project). Scientific Polar Research: the pavilion will reflect the importance of the seventeen scientific projects that Spain is undertaking as part of the 6th International Polar Year, in both the Arctic and the Antarctic. Technological Management of Water: Spain is a pioneering country in the regulation of hydrographical basins, of which the Ebro is a model. It also shows the role of the desalinisation plants, purification plants and the modernisation of irrigation systems.
The pavilion could not miss out on a reflection on climate change in its displays. Thus, the Spain Pavilion presents the exhibition Climate Change, produced under the direction of Jorge Wagensberg, director of the Area of the Environment and Science of the La Caixa Foundation. It presents the latest scientific research in this field, with the collaboration of world-class experts.
Noteworthy among its contents are the analysis, in a didactic yet rigorous way, of geological time, biological time and human time; the fundamental laws of Nature; and the different models of interaction between ecosystems.
In keeping with the repeated position maintained at all types of international forums, Spain wishes to comply with the Kyoto Protocol. The change in mentality that such compliance involves also affects a sector with high environmental impact, construction. It is the guiding thread of the exhibition ZaragozaKyoto.Architectures for a sustainable planet, curated by the architect and Project Chair of the School of Architecture of Madrid, Luis Fernández Galiano.
The show presents ten architectural solutions by renowned Spanish and international architects whose works promote sustainable architectures: Ábalos and Herreros, Ecosistema Urbano,Thomas Herzog, Françoise Jourda, Rick Joy, Diébédo Francis Kéré, Lacaton and Vassal, Jaime Lerner, Pich and Aguilera, Sauerbruch and Hutton.

Restaurant and reception rooms
The pavilion boasts a restaurant representative of Spanish high cuisine, with two dining rooms –seating ninety and sixty diners. Next to the restaurant, the pavilion has a multiuse room for a hundred and fifty people for use by the autonomous communities as an extension of their own pavilions for tastings, conferences, spectacles or any other type of activity.


Supportive shop: fair trade, responsible consumption
In keeping with the environmental preoccupations that inspire both the pavilion and its contents, the management of the shop has been entrusted to the State Coordinator for Fair Trade, which groups together the marketers of ethically committed products and linked to different NGOs. Here, visitors can purchase ecological, supportive products whose benefits go directly to Third-World producers as well as scientific curios and SEEI promotional articles. Publications by the pavilion and others published by the ministries of Agriculture, the Environment and Education are also available.

Other spaces
VIP rooms, press and meeting rooms, spaces for workshops and a cyber-corner complete the Spain Pavilion, in which visitors are attended to by hostesses and instructors wearing uniforms especially created by the designer Miguel Palacio.

The Spain Pavilion according to Patxi Mangado
Reproducing the space of a poplar or bamboo grove on a watery surface has been the basic objective. On one hand we created a build mechanism capable of generating incredible possibilities from the point of view of energy logic and environmental commitment, an issue that is basic, fundamental and emblematic for the Spain Pavilion at the International Exhibition of Zaragoza; but on the other, one of the most attractive spaces, in physically and lighting terms, that we can encounter is taken to the architecture. Changing spaces full of suggestions and nuances where concepts such as verticality and depth play a fundamental role.
Is it possible to artificially reproduce a natural occurrence? An old frustrated aspiration of architecture. However, in this case it is possible to approximate it given that the geometric force of the metaphor plays in our favour. Moreover, the proposed image gives the necessary symbolism to what a Pavilion must be, in this case that of Spain, in a universal exhibition. The metaphorical reference where water is present through the referenced landscape is powerful and evident.

Execution. Pieces
The execution is easy and clear. The vertical elements can be made in the factory. They have a metallic nucleus encased in pieces produced like drinking jugs, equal pieces that when in contact with water absorb it to generate the air currents that operate as microclimates.

The way they are braced is easy and simple and has the goal of ensuring its structural unity, and is based on the same scheme we find in many plant nurseries in order to keep trunks and stems upright.
Roof
A great roof resting on all these profiles covers the pavilion. A very useful roof, given that its thickness (three metres) can house energy saving systems while regulating the light by resorting to the depth that makes the highly controlled rays play and reflect against the pillars and the watery surface at the base. The roof is covered in recycled chipboard panels.

Exhibition spaces
They are excavated voids. The forgings hang from the roof and are simply braced to the pillars. They are built from timber beams also made from recycled chipboard and resin. The external enclosure is in glass, though it is planned to anchor mobile partition systems with acoustic insulation to the structure to make them visually and acoustically airtight, necessary for both some of the exhibitions and for its future use as a cinema centre.
