Text description provided by the architects. As the philosopher, Gilles Deleuze says: « Believing in the world is what we miss the most. We have completely lost the world. We have been dispossessed of it. » 

Effectively, today's youth is stuck between, on the one hand, the denial of the latest climate-skeptics and, on the other hand, collapsologists warning us of the probable collapse of our civilization incapable of quickly reinventing itself to face the challenges of climate change.

The theme of Expo 2020 Dubai, which opens on October 1, 2021, is "Connecting Minds, Creating the Future". Associated agencies "Vincent Callebaut Architectures" and "assar architects" wanted to use this leitmotif to unite their respective expertise and clearly proclaim to the youth that architects and citizens are now able to co-build ecological, inclusive, and solidary cities.

The Belgian pavilion is called "The Green Arch", as it combines intensive greenery and futuristic design in solid wood. The pavilion aims to be exemplary in terms of sustainable development. It is an ode to a regenerative circular economy, to biobased and geo-sourced materials, to the integration of bioclimatic rules and renewable energies, as well as to the preservation of biodiversity and nature.

Located in the “Mobility District”, the architectural concept of the Belgian pavilion is to offer visitors the largest shaded and naturally ventilated agora in the axis of the prevailing west-east winds of Dubai. Its programming is placed higher up so that a maximum of the ground floor space is free to use for the public.

This means that “The Green Arch” is based on a “bridge-building”, creating an immense vault with double curvature between its two pillars. This curvaceous vault is generated from a universal mathematical minimum surface called "hyperbolic paraboloid". This paraboloid is built in CLT - Cross Laminated Timber - with more than 5.5 linear kilometers of spruce louvers generating a giant wooden Mashrabiya - which by rotating of 180 degrees - envelops the entire project to better protect it from solar radiation.

The agora was designed as a "shortcut”, directly linking the “Mobility District” and the “Sustainability District” by crossing the pavilion. The street furniture of the public spaces on the ground floor was entirely made of 3D-printed white concrete.

In addition to Belgian staples such as French fries, waffles, and chocolate merchants as well as the bistronomic restaurant, the pavilion offers a view of the Belgian landscape of 2050 under the slogan “2050 Smart & Green Belgium”. Starting at the meeting space under the arch, great Belgian personalities draw like comic book characters announce the breadcrumb trail of the educational scenography imagined by our partners' Facts and Fiction. 

The scenography is broken down into 4 highlights: First, the futuristic escalator, designed as a space-time tunnel, propels visitors towards the 2050 odyssey. Secondly, once again accompanied by the Belgian comic heroes, the “Future Mobility Lab” provides the three regions (Brussels, Flanders, and Wallonia) to exhibit the means they implement to move towards soft and low mobility-carbon at the national level.  Third, the “Main Show” offers an immersive video-projection experience that erects a sustainable and resilient Belgium skyline for 2050. And finally, the “Belgium Mobility Hub” invites everyone, young and old, through unprecedented dynamic capture, to project themselves into the Belgian cities and ecological architectures of tomorrow.

At the end of the exhibition, visitors are invited to taste Belgian specialties in the bistronomic restaurant "BeHappy" or on the panoramic rooftop offering breathtaking views towards the main dome "Al Wasl" to the East or towards the thematic pavilion of the “Mobility District” to the West.

The “BeBizz” Business Center and its VIP Lounge also offer a high degree of flexibility in amenities to host business talks and international dialogues, to connect minds, and create a desirable future.

Symbolically, this slender bridge-building represents the dynamism and the plural singularity of federal Belgium and its Regions. Belgium is stronger when it is united!

It is a dynamic monolith dedicated to renewable energies, covered with a large photovoltaic and thermal solar canopy, producing electricity and domestic hot water for the pavilion's self-consumption.

It is also a biophilic architecture that hosts a rich program whose balconies and rooftops are planted with intensive revegetation of more than 2,500 plants, shrubs, and trees. These “breathable”, drip-watered facades, naturally refresh - through evapotranspiration from the plants - the large outdoor terraces where having fun is encouraged.

“The Green Arch” perfectly expresses the concept of “Belgitude”, this typically Belgian aptitude for synthesizing in the heart of Europe the very creative Latin romantic spirit with the pragmatic ingenuity of Germanics and Anglo-Saxons.

The construction is the result of a public-private partnership between General Commissioner BelExpo, the Régie des Bâtiments, and the Besix construction company. In total, 93 companies took part in the project, 46 of which were involved in sponsoring the pavilion designed on the principles of the circular economy as a giant Meccano. "The building will not be doomed to destruction," said Pierre-Yves Dermagne, the Belgian Federal Minister for the Economy. "Everything has been done so that it can be rebuilt, I hope, in Belgium."
