“Our vision for Urban bridge: regenerating ice sheet is to create independent urban habitats in Greenland that include technical functions to slow down ice melting.”
The world faced the complex patterns representing the natural environment were collapsed, climate is changing at a rate exceeding most scientific forecasts; arctic sea-ice is disappearing at a stunning rate, oceans warming, air pollution and climate change were caught in a self- boosting loop. Global warming was becoming irreversible and worse. Levels in Arctic and Antarctica raised to an unprecedented number in 4 million years. The problem with human-induced climate change is that it is occurring at a much faster than natural climate. Therefore, we grasped the urge to take action. Our vision for Urban bridge: regenerating ice sheet is to create independent urban habitats in Greenland that include technical functions to slow down ice melting. On Earth, the only continent where the ice cap polar climate is predominant is Antarctica. The Arctic is a vast polar region comprising the northern most parts of Canada, Norway, Greenland (Denmark), Sweden, Finland, the United States (Alaska), Iceland and Russia. The northernmost part of the Eurasian land mass, from the extreme northeastern coast of Scandinavia and eastwards to the Bering Strait, large areas of northern Siberia and northern Iceland have tundra climate as well. Large areas in northern Canada and northern Alaska have tundra climate, changing to ice cap climate in the most northern parts of Canada. (see Figure A.1).

Sea level is rising, in part, because melting glaciers on land are adding more water to Earth’s oceans. Glaciers – large sheets of ice and snow – exist on land all year long. They are found in the mountains of every continent except Australia. Greenland and Antarctica contain giant ice sheets that are also considered glaciers. As temperatures rise, glaciers melt faster than they accumulate new snow. As these ice sheets and glaciers melt, the water eventually runs into the ocean, causing sea level to rise.

When sea levels rise rapidly, as they have been doing, even a small increase can have devastating effects on coastal habitats. When large storms hit land, higher sea levels mean bigger, more powerful storm surges that can strip away everything in their path, as shown in Figure A.2.

As with the glaciers and ice caps, increased heat is causing the massive ice sheets that cover Greenland and Antarctica to melt at an accelerated pace. The meltwater from above and seawater from below is seeping beneath Greenland’s effectively lubricating ice streams and causing them to move more quickly into the sea, as shown in Figures B.1B.4.

Site Analysis 1: Challenges & Opportunities Arctic sea ice reaches its minimum each September. September Arctic sea ice is now declining at a rate of 13.2 percent per decade, relative to the 1981 to 2010 average. In addition, Arctic sea ice has thinned significantly over the past half century, and its extent has declined by about 10 percent in the past 30 years. (see Figure C.1).

As the ice disappears and soaring temperatures alter the life cycles and abundance of their prey, a growing number of indigenous communities face food shortages. In recent years, the Arctic has been at the forefront of political and social issues. Several matters have risen surrounding the issues of poverty and global warming and their effects on indigenous people in this region. Indigenous populations that were once largely selfsufficient and relatively food secure in the Arctic’s harsh environment are today struggling to sustain themselves as a result of poverty and also the impacts of climate change.

The polar climate regions are characterized by a lack of warm summers. Every month in a polar climate has an average temperature of less than 10 °C (50 °F). Also, The sun shines for long hours in the summer, and for many fewer hours in the winter. (see Figure C.2). ) (JAN MER °F) SUM°C (-40 -34
The polar night occurs in the northernmost and southernmost regions of the Earth when the night lasts for more than 24 hours. This occurs only inside the polar circles. The opposite phenomenon, the polar day, or midnight sun, occurs when the Sun stays above the horizon for more than 24 hours.

Food insecurity happens when strains are placed on food systems, making food inaccessible, unavailable and/or insufficient quality. In the Arctic, food insecurity is induced by food quality, availability.
Now, as sea ice becomes an increasingly unreliable hunting platform and soaring temperatures alter the life cycles and abundance of prey species, some indigenous communities are facing worsening food shortages and a lack of proper nutrition. More than one-third of households in the vast Arctic territory of Nunavut lack access to safe and healthy food. According to several recent Canadian studies, one-third to two-thirds of the households in the vast Arctic territory of Nunavut lack access to safe and healthy food. In some places in northern Quebec, soup kitchens are having trouble keeping up with the demand, and food scarcity has been linked to the slow growth of many Inuit children, as shown in Figures C.3. In Canada, Nunavut reported the highest rates of food insecurity; 56% of the Inuit population is classed as food-insecure compared to the 14.7%, which represents the Canadian average.

Design Concepts: Topography & Urban Shaping
the building.
As mentioned above, Our mission for Urban Bridge is to create independent complexes (in terms of energy and mobility), regenerate ice sheet and reverse the process of climate change and its impacts on the earth. In this perspective, we researched ice stream direction in our site, as shown in Figure D.2. Then we decided range that we going to regenerate snow on the top of mountain.
On the highest floor in technical layer, there is a hyperloop and metro platform from which people can either leave immediately or go to the other urban habitat areas. The platforms, on which comes hyperloop are on the several floors. In addition to public transport, transportion hub connects to public space such as parks that are located between technical layer and urbans layer (see Figure D.4).

The design of the infrastructure suggests two type of program. Technical part presents transportation and energy plant with lenear wall shape then, Urban habitats area show a dynamic environment where spaces for social interaction is established in several pockets throughout
In addition, urban layers follow the natural topography in greenland. It fits on the valleys, therefore it also contribute to improve the efficiency of preventing ice melting from the ice stream (see Figure D.3).

The project is organized into three main components: a high-density urban tower, a technical tower which includes hyperloop, public spaces and entertainment spaces that bridges between the two. The park landscape that mediates between the existing viaduct and the various access points throughout the site. Each of the three components are given their own unique character, and by blending them into a continuous field they produce a differentiated system that accommodates diverse and overlapping programs at a hyper dense urban scale.

The Tectonic of the roof system
During most of the season, the roof modules are controlled direction and angles that adjust sulight. As a general rule, the more variety of roof angles, the deeper into the space the daylight can penetrate, as shown in Figure E.7.
The concentrated “roof” of towers allows for a closer proximity between each high-rise while maintaining significant light, and air. In order to solve the problems between polar night and day. This project adapted two different roof technologies. We set up the cicle shape of module that has two sides. During the polar night (winter), modules are facing in one direction and generate artificial sunlight for normal life (see Figure E.5 -E.6). The opposite phenomenon, the polar day, or midnight sun, the roof reflects sunlight, therefore towers keep dark inside during the night time.

PLAN
Building Form & Program in a urban area As shown in figure F.1. Various shaping of the plan accumulate in a building. Some parts are more extending than the previous layer, and it could be connector with the mechanical layer, urban park, and bridge. In case of the facade, to look simliar with the surrounding environment, we make the double skin; one has the function of keeping warm inner area, and another has the transparency material for watching outer area from the inner. Also, the shaping of the crevice makes people to watch the outside. The location of the crevice depends on the location of the urban park.
