The largest tropical greenhouse in the world will be built in France

The territory of Northern France does not have a particularly mild climate, even though the entire region is close to the Gulf Stream. That is why this place was chosen for the implementation of an ambitious project - the company Coldefy & Associates wants to build the largest greenhouse on the planet near Pas-de-Calais. Its key feature is that it will be one giant super greenhouse building.

The Tropicalia project, despite its scale, is very simple in nature. A plot of land with an area of ​​20, 000 sq.m. will be fenced off from the outside world with a massive aluminum frame, on which ETFE panels will be fixed. It is a building material based on fluoroplast-40 polymer, which is distinguished by outstanding indicators of resistance to weathering. Plus it is lighter and cheaper than glass.

Representatives of the company say that they do not plan to install heating systems - on the contrary, they will also need to remove heat. It will be created due to the natural greenhouse effect, by heating a huge mass of air under the dome with the sun's rays. The working temperature inside the greenhouse is not lower than 28 degrees Celsius. There are options to create heat removal and storage systems, for example, for power generation.

A huge number of purely tropical plants will be planted inside the greenhouse, waterfalls, lakes and hills will be equipped, among which a hiking trail more than a kilometer long will be laid. Turtles and coral fish, hummingbirds and birds of paradise, flowers and butterflies from the tropics will be settled here. There will be restaurants, hotel, shops, etc. at the disposal of visitors. The capacity of the facility is estimated at 500, 000 people per year; it is expected to be built between 2019 and 2021.
