France to open World’s Largest Single-Domed Greenhouse
“Tropicalia” the world’s largest single-domed greenhouse, is set to open in 2024 in France’s Cote d’Opale. This enormous concept was submitted by a French architecture firm, Coldefy. And this single-domed greenhouse will extend over 215,278 square feet (20,000 square meters).
The greenhouse, which will be cut off from the rest of the outer world, will feature exotic flowers, butterflies, hummingbirds, Amazonian fish, turtles, caimans, water gardens, waterfalls, and ponds. Internally, load-bearing columns will be eliminated which will allow an unobstructed view.
Tropicalia’s designs are presently on show at the 17th Venice Architecture Biennale, which will run until November 21. Coldefy and Zuecca Projects, a non-profit organization, are displaying their grandiose ideas for this single-domed greenhouse which include architectural models, drawings, and videos.
Tropicalia is described as a ‘bubble of harmony.’
Tropicalia is an 115-foot-high (35-meter) structure which is designed to blend in with the surrounding natural environment. To achieve this blended nature, Tropicalia will be partially embedded in the ground thus reducing its height and impact. seamlessly blending into the French landscape with the addition of a second flora-covered external wall.The greenhouse will appear like a tiny hill from afar. According to the designs, Tropicalia is flawlessly integrated into the French landscape with the installation of a second exterior wall of flora.
France is a country with low temperature weather conditions. Average temperature of France is around 5°C (minimum) – 24°C (maximum). Therefore, the dome will be heated to 82.4°F (28°C) on the interior to ensure luxuriant flora. The roof will be built of compressed thermal pillows placed into an aluminum frame to prevent the heat loss.
In terms of energy, the entire facility will be self-sufficient. A double dome design is proposed for maximum thermal isolation, and all heat generated will be recycled and stored.
This double insulating dome will keep the tropical habitat in optimal temperature conditions.. This insulation will be reinforced by partial embedding of the greenhouse to the ground. As part of a network of private heat or a’smartgrid, the extra heat can be immediately used, stored, or transferred. At present the company involved with Coldefy has been switched to ENGIE. However, the structure and purpose of the dome still remain the same.
The greenhouse’s thermal energy will be recycled, and the excess energy will be exported through a heat network into surrounding buildings using Terraotherm technology, which is defined as an air-water heat exchanger with low energy consumption and minimum carbon emissions.
A 25 meter high waterfall, a 25 meter long pool with koi carp inside, and an Olympic-sized pool with Amazonian fish will all be featured in the greenhouse. These fish will be visible through a glass surface to visitors. The brave will be able to choose between a platform and a pontoon.
