In the wind and the growing epidemic and rising sea levels, including single family homes, office buildings, and even streets, floating cities built, low-lying areas become more suitable for human habitation

In the film directed by Kevin Reynolds "future water world", depicting the scene of the future life of humanity: the earth is one vast coverage, people had to live in floating man-made islands and abandoned ship. At first glance, the water in the house and the movie scene is somewhat similar. However, floating cities with water house as a guide will help people to better adapt to climate change, urban real estate prices continue to rise and the challenges of population.

Coping with the challenges of sea level rise

In the past 100 years, the sea level has increased by about 20 cm. According to the United Nations climate change experts estimate: by 2099, the sea level will rise by 18 to 59 cm. Sea level rise will give Bangladesh, China and Egypt and other countries low-lying, densely populated, agricultural development of the Delta region to bring devastating impact.

The urban population has surpassed the rural population the first time in the history. Is expected in twenty-first Century, the proportion of urban population to enter one step to reach 70%. 11 of the world's largest 15 cities are built in coastal and estuarine areas. The biggest of these two are Shanghai and Mumbai. Sea level rise will bring disastrous consequences for both. The United Nations Food and Agriculture Organization estimates that by 2030, India will lose 1000 to 2000 square meters of land, affecting up to 150 thousand people.

In view of climate change brought about by the impact can not be expected, the traditional land use and land reclamation are not sustainable response to the way. DeltaSync believes the floating city offers a better choice. For low-lying countries such as the Netherlands as, for instance, is constantly heightening dam, built floating city is one of the feasible alternatives. Like the water in the house can be changed with the corresponding rise in the water level, there is no need to change or rebuild. Safety of water on the roof is better some, because the dam may be destroyed, cracking, causing devastating flooding.

Floating city is also an effective way to solve the problem of population expansion and urban congestion, which can provide more land for urban construction. New York Office of the independent budget aims to provide the public with an objective and fair budget information. The Bureau's statistics show that in 2008 - 2009, the city's all middle school students, almost 50% of the students learning environment is too crowded. Floating cities can solve this problem. DeGraff, a civil engineering expert, said: "the floating city has a broad future. In high density population area, it not only increases the utilization of urban space, but also does not increase the threat of flood."

Self-sufficient water house

The world in a water house built in Rotterdam. It was built in Rotterdam city 50% of carbon dioxide emissions goals of environmental protection, to ensure Rotterdam to adapt to climate change in the future, to keep the city development vitality.

Rotterdam water house is used as exhibition and reception center, centralized management, to show the situation of water resources in Rotterdam city climate change and energy regulation. The water house is 12 meters high, the construction area of 4 the size of a tennis court, can accommodate about 500 tourists. It also has open square and circular roof, and a deck can accommodate 150 people.

Water house not only provides a new landmark for Rotterdam, and that the people of Rotterdam in the sustainable development and climate change efforts to the world. It can be said that the water house is Holland people's diligence and wisdom of the witness. Water house is impressive, has attracted the attention of the world.

Water house built by a number of innovative technology. In order to make the whole building to keep the state not the lightest sink, under construction used 5 layer of polystyrene foam, and the dome is made of ETFE film, the transparent material should be 100 times lighter than glass. The outermost layer of a coagulation plate, can prevent water erosion. With the rise and fall of the sea, the water on the roof will be adjusted automatically, which makes the water on the roof can well adapt to climate change. Water house is also used for thermal energy storage system. The system uses water as thermal insulation layer and maintain a sustainable supply of energy and water by solar panels. Water is through rainwater collection or draw from the sea. Water house by solar energy and surface water become self-sufficient in energy and water supply, even the toilet water will be purified by its own system.

In addition, the water on the roof can adapt to different environment. Engineer Bart Rofen explained that the ordinary housing only designed according to the fixed environment. But in the design of the water on the roof, taking into account the different geographical environment. The water on the roof can be parked in many places. From a technical point of view, the water house built three or four storey is no problem. The civil engineer DeGraff is currently working with the New York and other city officials for talks, they are beginning to study a data collection, in order to obtain a better understanding of the hydrological characteristics of different city.

The floating city is the vision of the future

Water house this groundbreaking move is just a number of floating construction of the pilot, the future will be the construction of a floating city. At present, engaged in water house project is not just DeltaSync company. Engaged in urban planning and construction of the "water studio" also introduced a "new waters" of the water house project. The project is moving towards a new relationship with the water. According to the "water studio" company architect Cohen Osas revealed that the project was awarded the 2009 World Building News Award, but also a leading project of construction". A total of 1200 residential construction of the project, which will be about 600 will be floating on the water. The planning area of the project is located in the lowest elevation area of Holland, between Hague and Rotterdam. This piece of land was reclaimed from the sea is a row of glass. However, now this is cleared of one empty, to make room for the new water project. Expert Osas said: "the construction work will be completed on the land. After that, we will destroy the dam and let the water in."
