Built on a reclaimed clay pit, The Eden Project is the largest greenhouse in the world, consisting of artificial biomes that house many different species of plants collected from around the world. It is located in Cornwall in the United Kingdom. The Eden Project consists of three enclosures, each emulating different natural biomes to represent three distinct climates found around the world. Biomes are eco systems that are characterised by distinctive plants and animals that share a certain climatic condition. The largest biome in the Eden Project emulates a tropical climate while the second one emulates a Mediterranean climate and the third is a roofless dome, which is an open area with varied plant life from the temperate Cornwall area as well as plants from similar climates. There is a computer controlled environmental control system that regulates the temperature and humidity of each dome. The domes are self supporting and require no internal support due its the geodesic structure. The geodesic structures are made from steel.
The panels are made from EthylTetraFluoroEthylene (ETFE), a hi-tech transparent foil.
ETFE foil is a perfect covering for a greenhouse because it is strong, transparent and lightweight. A piece of ETFE weighs less than 1 percent of a piece of glass with the same volume. It is also a better insulator than glass, and it is much more resistant to the weathering effects of sunlight.
