世界上最大的熱帶溫室——設計方案

法國公司Coldefy＆Associates已公布了世界上最大的熱帶溫室設計方案的圖像。位於法國Pas-de-Calais的Tropicalia將佔地215,000平方英尺（20,000平方米），擁有熱帶森林，龜灘，亞馬遜魚池和一公里長的步行道。生物群系旨在提供一個「和諧居所」，讓遊客立即沉浸在單一圓型屋頂下看似自然的環境中。

French firm Coldefy & Associates has unveiled images of their design proposal for the world』s largest tropical greenhouse under one roof. Situated in Pas-de-Calais, France, 「Tropicalia」 will cover an area of 215,000 square feet (20,000 square meters) featuring a tropical forest, turtle beach, a pool for Amazonian fish, and a one-kilometer-long walking trail. The biome aims to offer a 「harmonious haven」 where visitors are immediately immersed in a seemingly natural environment under a single domed roof.

與能源公司Dalkia合作設計，6200萬美元的Coldefy＆Associate計劃旨在創建溫室內穩定的26攝氏度環境。為了實現這一目標，建築師採用了鋼結構和ETFE塑料技術相結合的Nicholas Grimshaw伊甸園項目的類似解決方案。

Designed in collaboration with energy company Dalkia, the $62-million Coldefy & Associate scheme aims to create a stable 26-degrees-Celsius environment within the greenhouse. To achieve this, the architects adopted a similar solution to Nicholas Grimshaw』s Eden Project, using a combination of structural steel and ETFE plastic technology.

該方案將採用200英尺x 13英尺（60米x 4米）ETFE條的「雙圓頂」，形成加壓「緩衝墊」，允許紫外線通過，同時控制內部的熱環境。位於結構下方的第三層ETFE將積聚由溫室效應產生的熱量以用於熱能。為了進一步提高該方案的能源表現，並將大型建築與自然環境融為一體，穹頂將部分嵌入景觀中。綜合起來，這些措施創造了一種能量自給自足的方案，允許將能量重新分配給周圍的建築物。

The scheme will feature a 「double-dome」 of 200-foot x 13-foot (60-meter x 4-meter) ETFE strips forming a pressurized 「cushion,」 allowing UV light to pass through while controlling thermal conditions inside. A third layer of ETFE underneath the structure will accumulate heat generated by the greenhouse effect to be exploited for thermal energy. In order to further enhance the scheme』s energy performance, and to integrate the large structure with its natural surroundings, the dome will be partially embedded in the landscape. When combined, these measures create an energy-self-sufficient scheme allowing for energy to be redistributed to surrounding buildings.

這個雙層隔熱穹頂將在夏季保護熱帶生態系統並在冬季保持其溫度。部分埋藏的溫室將加強這種絕緣。因此，多餘的熱量可以直接使用，存儲或重新分配給周圍建築，作為私人供熱網路或「智能電網」的一部分。- Dalkia主要項目技術總監Denis Bobillier。

This double insulating dome will protect the tropical ecosystem in summer and maintain its temperature in winter. The partial burial of the greenhouse will reinforce this insulation. The excess heat can therefore be directly used, stored or redistributed to our neighbors as part of a network of private heat or a "smartgrid."

- Denis Bobillier, Technical Director of Major Projects, Dalkia

圓頂形成的環境條件為下面的「熱帶植物和動物的特殊綠洲」提供了可能。遊客沿著一條長達一公里的道路行駛，可欣賞到一個82英尺高（25米高）的瀑布，82英尺長（25米長）的「充滿錦鯉的觸覺池」和一個裝滿了亞馬遜魚的池塘，其中一些魚長到3米。遊客可以通過水族館式的玻璃表面體驗這些魚，或者通過平台和浮橋更加大膽地體驗這些魚。

The environmental conditions created by the dome allow for an 「exceptional oasis for tropical flora and fauna」 beneath. Visitors are led along a kilometer-long path, encountering an 82-foot-high (25-meter-high) waterfall, 82-foot-long (25-meter-long) 「tactile pool」 filled with koi carp, and an Olympic-sized pool filled with Amazonian fish, some growing up to 3 meters in length. Visitors can experience these fish through an aquarium-style glass surface, or more daringly, via a platform and pontoon.

為了配合熱帶環境，Tropicalia將包含禮堂，酒吧/餐廳，住宿加早餐以及致力於國家和國際合作的科學區，包含會議室，實驗室及診所。該計劃一經開業，預計每年將吸引50萬名遊客。

To accompany the tropical environment, Tropicalia will contain an auditorium, bar/restaurant, bed and breakfast, and a scientific area dedicated to national and international collaboration, containing a conference room, laboratory, and clinic. When opened, the scheme is expected to attract 500,000 visitors per year.

該項目將於2019年開始動工，計劃於2021年開放。

Tropicalia is due to begin construction in 2019, with a planned opening in 2021.
