Austria has completed the first stage of construction for its pavilion at Expo 2020 Dubai.
A cone with a diameter of seven metres at the base now stretches up toward the sky, and 37 more cones will be built on the 2,400 sq m site over the next two months.
The cones will be cut off at different heights ranging from 6 to 15 metres and interlaced with one another, a statement said.
In the exhibition area, the cones are open at the top and form a “semi-exterior” to create unique light and shadow effects in the interior, while also playing a key role of the pavilion's climate concept.
Inspired by wind catchers used in traditional Arab architecture, the different cone heights lead to constant, cooling air movement. Together with night-time ventilation and the high thermal mass of the cones, this creates a pleasant room climate in the exhibition area using natural methods.
Organisers said the room temperature in the Austria Pavilion will feel pleasant even in periods of hot weather, and the building requires 70 percent less energy than a conventional, climate-controlled building.
"Our goal is to construct a sustainable building that consumes very few resources and is easy to take down again after the event,” said Gerd Erhartt from the architectural firm Querkraft.
He added that the use of prefabricated parts makes the Austria Pavilion easy to dismantle: Each cone is made up of concrete elements that are precast in Dubai.
They are transported to the construction site by truck and assembled on-site using couplers. The individual elements will be reused after Expo to create a new building at a different location on the Arabian Peninsula.
“The sustainable, responsible use of resources has a long tradition in Austria. Expo 2020 Dubai will be the biggest event in the world this year and will thus provide a global podium for the key questions of our time. We want to use this forum to showcase prototypical future scenarios for climate-neutral and resource-efficient buildings of tomorrow,” said Commissioner General Beatrix Karl.
The country’s pavilion at Expo 2020 Dubai is located in the Opportunity district. Austria’s participation is being financed with funds from the Austrian Federal Ministry for Digital and Economic Affairs and the Austrian Federal Economic Chamber.
