The Title:  Aquapolis 2020

NAME:Chao Wang              CITY:South Tungchow City,China
PROJECT SUMMARY:

As climate change,global warming of the ocean and the air will accelerate the melting of the ice sheets.The rise in sea level may well threaten our homeland,especially the cities close to the seaside.What these coastal cities will be?Will they just submerge and people who live in them leave thier home?Or will they accommodate the changes and utilize the new situation?Will we live above the sea instead of next to it?The project Aquapolis 2020 gives a vision of the city above the sea in the future.

In order to build resilience to the climate change, peak oil and also the increasing density,the Aquapolis establishes its urban systems around following principles:

Carbon Neutrality — To achieve carbon balance,on one hand,we reduce the carbon dependency of the city which most comes from buildings and transportation. On the other hand,we establish diverse urban green systems to impove the carbon absorbency.

Local Self-Sufficiency — We create more sustainable supplies of goods and services including food, power, freshwater and also R&D capacity both for the city and the region.

Systems Diversity — The diverse power generating systems which includes:

The Wind-power Generator

The Tidal-power Generator

PV panels

The diverse water cycling systems which includes:

The Seawater Desalinization System

The Irrigation System

The Sewage Treatment System

The diverse food harvesting systems which includes:

The Urban Farmland System

The Vertical Farming System

System Hybrid — To increase the working efficiency of systems and reduce the energy lost during the operation,we intermix the interrelated systems together,combine them into a hybrid system.

High density&Mixed used — To accommodate the increasing population and to satisfy various demands whithin limited land,we plan the city in a extremely hign density and intensely mixed function.

WHERE WE (WILL) LIVE

The site locates in Lvsi,South Tungchow City,China which is in the west bank of Yellow Sea.Thousands years ago,the land was still beneath the wave.Today,the rise in sea level caused by global warming seems to push the city into ocean again .If we could not aviod all these happen, what could we do then?Do we have the only choice ,which is,we have to leave our homeland?

Besides,we still have to face the threats from peak oil.As a developing city.The consumption of petroleum is keeping growing.When the oil runs out,what else can we use to drive our machine in the near future?

In the meantime,the increasing density also troubles us.Due to rising seawater swallowing our land,we can not solve the overpopulated problem through the endless urban sprawl.And the food issue seems to be more urgent because of both the reducing farmland and increasing demands.

WHAT WE (WILL) HAVE

What do we have today?

Luckily,where we live is one of the best place to generate wind power.The average wind speed at the hight of 70 m comes up to 7 m/s.And as a result,we have the largest windmill plants in Asia.

Apart from this,we have rich resouces of tidal energy.The average tide range comes to 3.91m,and the extreme tide range comes to 5.95m.(The tide range higher than 3m could be used to generate electric power in theory)

Then what will we have tomorrow?

Plenty of seawater,of course.

The latest Urban Plan of South Tungchow City(2010-2030) represents a city in large scale,connected by extremely dense road network.But once the sea water sweeps,we'd have to build more and more dams and excavate more and more rivers so that the land is limited by the dams and the road network becomes river network.Will the plan still work in that time?

Problems

Today,the rise in sea level caused by global warming seems to push the city into ocean again .If we could not aviod all these happen, what could we do then?Do we have the only choice ,which is,we have to leave our homeland?

CARBON DEPANDENCY

Apart from the industry,Buiding and transportation consume the most part of energy.

Today in China,most of the energy comes from the combustion fo coal, petroleum and natural gas which produce a large amount of CO2 emmisions .

GLOBAL WARMING

TEMPERATURE RISE ,CHINA,2007

Between 1980 and 2004,annual carbon dioxide emissions tripled in China.Since carbon dioxide is the major cause of the so-called Greenhouse Effect,the increasing emission leads to a global warming.The annual temperature rises approximately 0.6 'C per year in recent years.

SEA LEVEL RISE

As climate change,global warming of the ocean and the air will accelerate the melting of the ice sheets.The rise in sea level may well threaten our homeland,especially the cities close to the seaside.

Many cities will be the sinking city as well as the famous Venice.

LANDUSE&TRIFFIC ISSUE

LAND RESOURCES REDUCTION

once the sea water sweeps,we'd have to build more and more dams and excavate more and more rivers so that the land is limited by the dams and the land we could use reduces.

TRIFFIC ISSUE

As the road network becomes river network,the motor vehicle travel becomes big problem.We have to change our transportation system to fit the new situation.

SOLUTIONS

1. DAMS AS BOUNDARY

To proect us away from flooding,many artificial rivers are excavated and many dams are built around the city.As a result,unlike the other cities,which do not have the clear boundary generally,the Aquapolis is surrounded by the dikes and dams which become the border at some time.

2. NON-CAR CITY

Inside the city,instead of road network,the river network divides the land.As a result,there is hardly a car but hydrogen-powered yachts and bikes in Aquapolis.Indeed,the rivers and the bridges across the rivers make up the internal transport system of the city.And the harbor and the railway station are used to connect with the other cities.

3. "LANDING STAGE"

To utilize the Wind power and Tidal Power,a "Landing stage" extends to the yellow sea,on which wind power generators and tidal power generators are installed.

4. FOOD HARVESTING SYSTEM

Except the building bases,most of the land is utilized for urban agriculture.It makes up the food harvesting system with the vertical harvesting towers.

5. ROOF GREEN

Each floor of The buildings is staggered to make a space for roof green which increase the the green coverage.

6. WATER CYCLING SYSTEM

To ensures the operation of the urban green system we establish the water cycling system.The system could provide the fresh water not only for domestic but also irrigation of the food harvesting system and roof green.And it could also filter the greywater and industrial waster water.

7. HIGH DENSITY & MIXED USED

Due to the reduction of the land,more rural population aggregate to the city.As a result,we plan the city in a extremely high density.At the same time,the strips of mixed used buildings insert into the land.High density and flexible functional division well fit the unpredictablly increasing demands of human in future.

ENERGY HARVESTING

Since our proposal minimizes the Carbon emission,we abandon the coal and petroleum which could produce a large amount of Carbon Dioxide during the combustion.As we have abundant wind-power resource and tidal-power resource, we build Wind driven generator and Tidal power generator to harvest clean energy.Apart from this,we use PV panels to get solar energy.

SYSTEM HYBRID

Though we establish diverse systems to operation the city and get resilience,some of the systems are related. And if we com--bine the interelated system,we could obviously improve the efficiency of energy utilization and reduce the cost of infrastructure.

As the Aquapolis, a city surrounded by seawater,we could get the freshwater via the Sea Water Desalination.During the evaporation method,the evaporator need heat to make seawater evaporating.The heat could get from the Temperature Controlling System while it is cooling the building.Correspondingly,the condenser could release heat which the Temperature Controlling System needed while it heating the building.At the same time,the pipes of the Water Cycling System could combine with the pipeline of Temperature Controlling System and architectural structure.And all this becomes a hybrid system.

  

Aquapolis 2020 — Farmland

Urban Farmland System

Farmland can be rehabilitated in fallow period and can be the infrastructure to form the sustainable ecological environment.People enjoy various city life at part of the farmland which is in fallow during one year.And it will be used as the space where people can experience the repeated seasonal changes.The designed place will gradually be turned afamiliar place in which nature and culture co-exist.

  

Aquapolis 2020 — No-Car Transport System

NO-CAR TRANSPORT SYSTEM

Inside the city,instead of road network,the river network divides the land.As a result,there is hardly a car but hydrogen-powered yachts and bikes in Aquapolis.Indeed,the rivers and the bridges across the rivers make up the internal transport system of the city.And the harbor and the railway station are used to connect with the other cities.

  

Aquapolis 2020 — High Density & Mixed Used

HIGH DENSITY&MIXED USED

Creating resiliency and reducing the carbon footprint of urban development requires us to maximize the active use of space and land.A single use low density landuse is inefficient and resource-wasting.While high density and mixed used allow for the effective functioning of all types of business, social and cultural activities with very low inputs of energy for transportation and logistics.And at the same time,the city buildings could stay resilient to the unpredictable future and the changing demand.

On the street pass through the railway station connected with zone of multi functional buildings including apartments,hotel,office and on the first floor cafes,shops,glleries and clubs.

Strip of tall mixed towers (50-60m high) standing on the bank of the harbor which include conference center ,exhibition center,office and hotel.And the strip also creats a wide walking street.
