City of the future: Floating, clean and vertical

According to many experts, the current construction trend places a priority on disaster preparedness. Therefore, the world of architecture and design are hard at work seeking traditional construction alternatives to ensure cities can be safe as climate change is becoming more complex. , rising sea levels, serious pollution, and rapid population growth.

In this context, the Independent (UK) has proposed three model city models of the future, with the belief that the rapid development of science and technology will help people increase their ability to cope with threats. in the future.

Floating city

Recent reports show that 90% of the world's largest cities will be in danger because of rising sea levels by 2050. Recognizing this danger, the Independent said that it was time. consider building a floating city, especially for areas that are at risk of sea encroachment.

The concept of the floating city Oceanix is very welcome, with the structure of integrating the floating floors through the bridge system, so that the construction of housing, work, entertainment and business above the floating floor. The entire floating floor will be firmly anchored under the sea floor, and strictly tested for the level of response to weather conditions at sea.

Oceanix floating city is considered as a solution for areas at risk of sea encroachment.

By design, inside Oceanix will include many town complexes, each town has 6 villages linked together, creating a living space for at least 10,000 residents. Oceanix will connect to the mainland thanks to a modern transportation system that uses electricity and solar energy, allowing movement between towns and out to the adjacent coast.

Ecologically, Oceanix uses 'biological stones' that act as artificial corals attached to the bottom of the floating floor, thereby creating a habitat for many marine species, helping to promote the cleaning of water as well. such as ensuring sustainable ecological development.

Besides Oceanix, a smaller floating city model has been tested in a number of countries to take full advantage of the water space. In Denmark, the Urban Rigger dormitory has been completed, with its unique floating ability, which is made up of containers that are joined together in a triangle.

This unique building also comes with a 'floating garden', which allows vegetables and fruits to be planted on a movable barge. The 'floating super island' model is also being implemented in the first phase in the Netherlands, with 87% of the multi-sized floating triangles made from steel, which can stretch for 1.5-2km, housing, ports, Farms and parks. Meanwhile, the idea of ​​the prefab floating city to solve the problem of China's population explosion created a vast land area at sea thanks to the combination of hexagonal islands.

Currently, the United Nations has launched the project 'Space in the Sea', and received about $ 200 million to support conducting research on floating cities, to assess weather - tidal and energy use of floating designs, as well as the ability to affect the habitats of marine life and the mechanism of operation of agricultural and fishery farms to ensure subsistence.

It is predicted that floating city technology could be deployed in the next 10-20 years, becoming part of a 'green future' towards sustainable options to take advantage of the 70% ocean and ocean coverage. Earth's surface area.

Non-carbon city

The reality of serious urban pollution has given rise to the idea of ​​building cities with less carbon emissions. One of the most outstanding projects is Masdar, a non-carbon city in Abu Dhabi expected to be completed by 2020.

Experts say that Masdar will become the first place in the world to have a carbon concentration of approximately 0 thanks to the mechanism of fully using renewable energy. In Masdar, tall buildings will be put together to provide shade in the narrow aisle leading to the large yard. In addition, a wind tower was built to take in the air above, bringing a cool breeze into the city, making the average temperature of the city of about 40,000 people at only 35 ^° C (different from the heat. up to nearly 60 ^° C in Abu Dhabi).

Cities such as Masdar or PlantIT Valley have nearly carbon concentrations near zero thanks to the full use of renewable energy.

The unique feature of Masdar is that energy recycling and conversion activities are fully utilized to reduce waste to almost zero, and the amount of carbon and industrial emissions are almost negligible. The city will have a walking system and a public transport network powered by solar energy, or electric cars.

The underground transportation system is also invested, with over 1,500 bus stops and trams. Masdar City also plans to collect energy from large solar cells shaped like flowers. During the day, cells open, store energy and provide shade for pedestrians, and they close at night to generate electricity. This could help Masdar generate excess electricity, thereby selling the surplus to the Abu Dhabi city power grid.

Masdar was developed with the vision of a global center for renewable energy and clean technology, inspiring many of the carbon-free urban ideas around the globe. At the end of September 2019, carbon-zero housing development project was approved by Peterborough City Government (UK), in response to the green urban development program.

The design includes a sustainable urban drainage system, a carbon-free power generation system along retail stores and public facilities. The apartment complex will have grass roofs and green walls, located on a 300m² supermarket.

The Portuguese government, meanwhile, is planning to build the ecological city PlantIT Valley in the South, using computer 'brains' to manage water use processes, waste treatment and energy consumption. amount. PlanIT Valley will operate in an efficient loop cycle, recycling or reusing wastes, aiming to become the greenest urban city in the world.

Vertical city

According to experts, vertical cities will save extremely effective area, can completely solve the problem of lack of accommodation due to population growth. This is explained by the vertical development structure, which allows hundreds of thousands of residents to live in a single building block.

By design, the upright city consists of many buildings, used for many purposes such as apartments, hotels, or shopping centers. Residents will move by horizontal and vertical sliding lifts, absolutely no noise and pollution of vehicle exhaust. When cities only 'grow' high, not horizontally, it is possible to minimize wasted land.

The idea of ​​vertical cities helps solve the problem of lack of accommodation due to population explosion.

The upright city is approaching the most sustainable lifestyle that developed countries are looking forward to. An architectural firm in Italy outlined a project of a 180-storey tower in the United Arab Emirates, promising to create green living spaces for nearly 30,000 residents.

The city will use solar cells, made of photovoltaic glass panels that can provide enough electricity and electricity for the entire building, promising to reduce up to 50% of the CO2 that is polluting the environment.

In addition, the vertical city is a new trend in creating buildings for the 21st century with ecological designs inside, most clearly seen through the idea of ​​building the Bionic tower in Shanghai. The tower has a capacity of over 100,000 people and has a height of 1,200m, equivalent to 300 floors, located on an artificial island connected to the mainland.

Bolder, the Paris-based architecture firm OXO is about to materialize the vertical city of City Sand in the middle of the Sahara desert, with the ambition to provide high-density housing for residents amid the arid climate of the sa The desert includes residential areas, offices, hotels, entertainment centers and a museum.

According to the design concept, the vertical tower will have a height of 450m with an area of ​​about 800,000m², installed rainwater collection systems, generating electricity from solar and geothermal energy. Inside City Sand, the architects plan to create a diverse vegetation in the center itself in the form of vertical gardens, act as a shield to protect residents, and help combat the climate. harshness of the desert.
