Architect Gabriel Kozlowski has proposed a stunning, energy-producing structure for the Brazilian pavilion at Expo 2020 Dubai. Created in collaboration with Gringo Cardia, Bárbara Graeff and Tripper Arquitetura, the conceptual design showcases a variety of sustainable systems, from construction materials like rammed earth to passive solar design strategies. Although the competition entry was not ultimately chosen for the Expo, the design does offer an inspiring look at the integration of Brazilian identity into sustainably minded architecture.
“Our pavilion is inspired by one of the greatest technological achievements of Brazil: the improvement of the Direct Planting System over straw,” Kozlowski explained in a project statement. “This agricultural technique protects the soil and maintains the ideal thermal conditions for cultivation. The pavilion conceptually mimics this scheme through its layered arrangement — soil, entanglement of protection, productivity — presenting itself as both a building and a symbolic image of one of our progresses.” In addition to its nature-inspired form, the pavilion proposal subtly references Brazil’s previous Expo pavilions including those of Paulo Mendes da Rocha at Osaka 1970 and from Sérgio Bernardes at Brussels 1958.
The building would have been built primarily of laminated timber as well as rammed earth mixed with reinforced concrete. The ground floor would serve primarily as exhibition space and is designed to host the ‘Together for Nature’ exhibition organized around six walls, each symbolic of Brazil’s six main terrestrial biomes: the Amazon Forest, the Cerrado, the Atlantic Forest, the Caatinga, the Pampa and the Pantanal. Each wall would be made from the soil of each biome and surrounded by totems housing the seeds of native species.
A massive, nest-like structure made from woven tree branches would appear to float above the ground floor and is accessed via a spiral staircase. The upper level would house the ’Together for People’ exhibit with images showcasing Brazil’s ethnic diversity along with the ‘Together for Tomorrow’ exhibit that explores water-related, biotechnological advancements, such as desalination and aquaculture. The upper level would have also included an auditorium and gathering spaces as well as a landscaped rooftop with a lookout terrace and restaurant. The proposed pavilion would have been engineered to produce its own energy, recycle its own water and stay naturally cool without the need for air conditioning.
