LAVA’s design for the German Pavilion Expo 2020 Dubai is a vertical
campus of nature and technology, taking cues from the local architecture
and Germany’s history of outstanding lightweight pavilion design.
Demonstrating the Expo theme, everything from intelligent use of local
climatic conditions to materials reuse to construction is sustainable.
On behalf of the German Federal Ministry of Economy and Energy, Koelnmesse
GmbH is responsible for the organisation and operation of the Pavilion, with
Consortium German Pavilion EXPO 2020 Dubai facts and fiction GmbH and
ADUNIC AG (concept design, planning and implementation) and LAVA
(architecture/spatial concepts).

The airy construction is an efficiently stacked volume of space. A visually striking
freeform roof encloses a spacious volume and an intelligent ensemble of
interlinked floating cubes housing exhibition and event spaces. The contrast of
enclosed air space and immersive exhibition experiences generates an exciting
exchange between interior and exterior spaces. The open structure is formed
from abstract elements and surprising materials, a composition of repetition and
The concept continues German innovation in Expo pavilion design by using new
ways of forming space – from Mies van der Rohe’s Barcelona 1929 to Frei Otto’s
Montreal 1967 to Fritz Bornemann’s spherical concert hall Osaka 1970.
It also responds to the local climate and references the local courtyard house with
closed exterior facade and rooms oriented towards an inner airspace.

An opaque trapezoidal single-layer ETFE membrane creates a large volume of
space with a minimal enveloping surface and highly efficient material. The
metallic skin lets light rays into the interior through many small openings, similar
to sunlight penetrating forest foliage, creating a continuously changing visitor
experience. Mirror surfaces reflect direct sunlight against the roof skin, a dynamic
interplay of light. At night, a field of LED lights integrated in the ceiling make the
building radiate from within. Supported by vertical steel cables, the cloudscape
roof keeps out the heat and controls light and temperature in the atrium. It
reduces production energy, optimises resources by weight savings and creates
the technical conditions for a pleasant visitor experience.

A central atrium, a green, open space, connects all visitor areas and allows many
surprising perspectives. The composition of exhibition spaces, event area and
restaurants are interwoven through these manifold visual relationships. The
pavilion tour brings visitors continuously onto the terraces of the open atrium,
providing an overview of their location within the pavilion, the variety of topics
and social interaction with other visitors. Native German plants hang from the
terraces and roof creating comfort in the atrium and special light.

The vertical campus courses between a landscaped layer on the lower two levels
and the cloud roof. The rear east is a vertical backbone with technical facilities
and service functions, and the front western side houses exhibition and
restaurant spaces layered horizontally. The sequence of stacked seemingly
floating building elements is a journey through the campus learning experience –
from enrolment to learning curriculum to graduation. The ‘laboratories’, purposedesigned for exhibition, performance and dining, are grouped around the atrium.

The design continues LAVA’s philosophy of sustainability at multiple levels, a
strong visual symbol and example for visitors, by:

1. Material-optimised construction based on nature’s geometries.
2. Passive energy saving measures applied at the very outset in the design – for
example the stacked building elements not only trap vertical airspace, but
also minimise direct sunlight creating a sheltered atrium with minimal solar
input and optimised climate.
3. Intelligent arrangement creates different spatial situations, not through
complex technology, but rather through digitised production processes.
4. Minimisation of grey energy and operational energy.
5. Graduated climatic zones of individual areas allow reduced energy use, whilst
supporting the diversified room experience for visitors.
6. Reuse of building parts and materials - using algorithms to reduce waste
7. Barrier-free access.
Tobias Wallisser, LAVA director, said: “It exemplifies LAVA’s work with natural
geometries to generate efficient and beautiful structures and space through
intelligent skins using integrative technology and cutting edge materials. And how
buildings perform at many sustainable levels - environmental, structural and
Alexander Rieck, LAVA director said: “The project continues LAVA’s expertise
working in desert environments (Masdar Plaza UAE and more recently the
university masterplan and headquarters for KACST in Saudi Arabia.) The
integration of local climatic conditions, innovative use of recyclable materials and
ground-breaking climate control technologies demonstrate how one can build and
operate in harmony with the location.”

LAVA Director Chris Bosse said: “The challenge is: how does a country physically
represent itself in an exhibition like the Expo? World exhibitions give a glimpse of
the future from the perspective of their time. Our pavilion design shows
Germany's contribution to that view of the future. The sequence of different
spatial areas encourages visitors to have fun whilst learning.”
“The building itself is part of the exhibition, a tool for connecting people and
content, both a model of sustainability and a place to discover German
innovations and solutions on this important topic,” added Christian Tschersich,
Project Manager at LAVA.

The Expo 2020 theme is "Connecting Minds, Creating the Future" and it runs from
20 October 2020 to 10 April 2021.
