The international climate debate has in the recent years become more evident with diplomatic discussions and negotiations of levels of CO2 emission in accordance to the Kyoto agreement, how can we promote green growth, maintain enough food production, prevent global warming and subsequent rising sea levels etc. All very serious and important topics, but hardly anything that make an impact on you as a responsible citizen and contributor to the world’s climate challenges. Meet your neighbour states: A green initiative that combines environmental responsibility and economical as social benefits for the citizens of Skt Kjelds Plads and surroundings (entire site). This statement has been deeply saturated in our design of a new park at Skt Kjelds Plads, which will become the core of a strong identity for the area and connect and gather the neighbourhood community physically aswell as mentally.
The park has conventional recreational qualities and programmes addressing the close neighbourhood, but introduces a new element in the typical city programme: Four tall green towers. The towers work as green landmarks for the area and approach the entire city, giving the neighbourhood, but also Copenhagen, a strong (green) identity. It attracts together with the park a lot of social life and gives a green awareness among people in the area in general. The towers function as “urban vertical farms” and provides apart from environmental and social benefits to the city, organic vegetables to the area. One tower is intended for kitchen gardening and is an obvious place to meet new or old friends, and increasing the tolerance in the community. The park is all together a part of a huge sustainable strategy that harness different natural resources from the entire site. Rain water is collected and used to many things (cooling of buildings, toilet flushing, irrigation of soil, cultivation of algae etc.), sun energy is harnessed through algae production, greenery and food production helping to reduce the CO2 emission in the city (read more below).
Meet your neighbour has both an economical as well as a social advantages for the area. First of all drinking water can be saved, which is a very direct and measurable money saver for each citizen. Furthermore water from rain pipes can be used locally, instead of directing it into the sewers, which also costs the citizens money. The social advantages include a new social awareness of sustainability in the area! Sustainability is the common identity and is concretized into a form in the new park. The park can be experienced as a mixture of nature and urbanity; an island in the city. This is a park you use as a hub, perhaps you buy some locally grown groceries sold at the plaza or even take your dearest for a view in the towers. It is also a park in which you have the opportunity to engage more physically and socially. The open facilities in the park can be used for different venues; perhaps you wish to make a small fair or sell some of your extra groceries from your high kitchen garden you share with a new friend two blocks away. Either way the new park somehow is what makes, a term like sustainability, an impact in the everyday life of people in the area, both visually and mentally.
Next to the greenhouse a two pieced building is intended for education informational use, as well as a space for community cultural arrangements. This could be small concerts or other similar activities. A sports hall with training facilities is situated in the north eastern part of the park and share idiom with the auditorium, the greenhouse, the roofed hall and the towers. An important part of the park is a huge water sculpture. The sculpture reflects the amount of water collected in the area. In accordance to the total water balance the sculpture expands and contracts acting as a mirror of the season, functioning as a representation on the rainfall and as a delay basin. The park is grown with trees and well illuminated at night. The parking lot below surfaced gets diffused sunlight through small circular skylights in the park terrain.
park
The site is converted into a big new public park which is only accessible for pedestrians and cyclists. Below the park two new parking lots are established; these are accessed from the four different corner points. The park is open night and day and offers a more or less empty or open programme that works as anchor or meeting points in the park. A central space in the terrain is submerged and functions as a plaza. Here a flea market or a vegetable market with locally grown vegetables from the farm towers could be held once/twice a week. This place also functions as the hub for crossing from one place to another, whether you are a pedestrian or a cyclist. Biking lanes from all corner points link to each other and gives an easy access across the park. In the southerly part of the park we plan a building that has a shell character. This is a roofed open space that can be used for different venues. To the north there is a greenhouse. The greenhouse has opening hours but is open all year providing a pleasant, green interior that also can be used for different exhibitions.
glass and ribbons of algae containers (photo bio reactors). During the year the green colour of the algae ribbons fades or darkens thus creating a beautiful and dynamic facade. The green ribbons are a renewable energy source, which will be explained in detail later. Three towers are for urban farming and one tower is for kitchen gardens. All tower roofs are accessible for all and in all hours providing a certain experience and view of the city roofs. Growing your own crops is seen as a social activity which everybody regardless of social status can meet upon, generating a basis of neighbourhood self-awareness and a feeling of local empowerment.

climate challenges
To form the future of the city and its urban transformation, some of the challenges can be broken down into sub groups dealing with the different sides of the climate changes, and life in the modern urban areas. We are dealing:
The proposal on Skt Kjelds Plads facilitates our need to change perspective and rethink our cities differently in the future. The cities do not have an infinite pool of resources our behaviour affects the surroundings and causes environmental damage locally and globally. We have to reinvent the city more intelligently and synchronize it more fluently with the surroundings and the natural environment. The ecological footprint of the city can be reduced by using and harvesting local natural resources and in this manner become a more self-sustaining and self-sufficient city by producing what we are consuming. As well as creating new social urban possibilities through new meeting points, employment, empowerment , creating new topics to discuss, and making sustainability a local responsibility.
As the climate change is bringing more precipitation it becomes an increasing challenge to the cities sewers. The solutions are often to build new and bigger sewers. This is an expensive solution, which continues in the old tradition of seeing rainwater as something we have to deal with instantly directing it underground. The temperature during summer is rising, increasing the heat-island effect as the cities asphalt areas are large heat absorbers.
With rainwater locally. Treating, delaying, and diverting it during heavy rain. Thus reducing strain on the wastewater systems. With the temperature increase, focusing on cooling the urban surroundings and the buildings, and reducing the demand for air controlled cooling With the air pollution, reducing the particles and combustion gases from the motorized transport and the burning of fossil fuels. Reducing the air pollution, and lowering the CO2 emissions from fossil fuels. With the CO2 footprint, by introducing urban agriculture, that absorbs CO2 and thus reduces the city’s CO2 footprint With a transformation of the area into an approachable plaza leading to more social interaction and initiatives, making this an essential part of Skt Kjelds Plads.

making use of local resources: leading the water
Our proposal deals with rainwater as a blue resource. Making an effort in trying to prevent the floodings that arises as an effect of intensified rain events, raised water levels and occasionally storm, we are using the rainwater to grow vegetation and plants, but also as an evaporative resource that can help cooling the surroundings, lowering the need of cooling of buildings, and saving precious energy. The attention is on adapting to the future climate changes by combining and implementing a variety of blue and greening initiatives, including landscape-based rain-wa-
ter management, rainwater collection and utilization. Thus we are creating blue spaces on public areas and on nearby buildings. By re-using, delaying, collecting and redirecting the rainwater it becomes a new urban resource. We are doing this by collecting all the rainwater that falls on rooftops in the area of Skt Kjelds Plads. The water is purified through filters and stored in tanks under the buildings. The stored rainwater can be used for cleaning clothes and toilet flushing, which will save up to 40% of daily use of water (45 L/person). During summer periods the stored water will be used to cool down the building. This will save up to 60% of the energy for cooling systems. Some of the collected rainwater from the buildings will be used for irrigation of green initiatives that will be explained shortly. Excess water will be stored in tanks below ground and used in ponds and a big surface water sculpture that delays the water and lets the rainwater evaporate through the air causing a more comfortable microclimate during summer periods.
making a green resource loop
By recognizing the shift towards becoming more sustainable as a person, a neighbourhood and as a city, this new proposal for an eco-sustainable development of the neighbourhood of Skt Kjelds Plads revolves around using and introducing “the green” as a resource. Using the onsite resources, mean that the community do not have to import as much from other and often faraway places. In order to start a dialog of self-awareness, the idea of “thinking locally act globally” is made visible in an array of different but interlinked initiatives. We are introducing collective urban gardens and agriculture together with the production of bio-renewable fuel, based on locally grown algae in photo bio reactors (PBR).
short algae facts of algae and algae as a bio fuel
The green algae are one of the fastest growing plants on the planet, and the overall biggest consumer of CO2 It produces oxygen and hydrogen. Over 50% of algae’s bio mass is oil. This oil can be used to produce bio-fuels, a renewable energy alternative. The microscopic algae’s has a yield per hectare that is considerably higher than that of sunflower or rapeseed. It is possible to use this oil as bio-oil, or as a component in the cosmetic industry, furthermore algae can be uses as a fertilizer in agriculture and gardening. Using it as fuel in the motorized transport have some positive side effects as bio-diesel produced using algae contains no sulphur, is non-toxic and highly biodegradable.

The diagram summarizes what is discussed in the text. In “meet your neighbour” our solution for four climate challenges branches out in three categories. Each category has its own colour resembling our green and blue initiative together with a yellow colour indicating the human or social aspects of the project.
Using the local resources as a catalyst to urban transformation, the new Skt Kjelds Plads uses algae as a component in harnessing the pollution into renewable energy. Furthermore the algae introduce a greening element to the neighbourhood, providing a way of getting rid of some of the pollution coming from cars, and turning it into a renewable bio resource. The sustainable benefits of algae as a local resource are:
Lowering the demand of fossil fuel.
the energy generating facade
Photo Bio Reactor panels is used as a component in the facade of the towers on Skt Kjelds Plads. This is where the algae are cultivated. The facade structure is 50 % transparent components (glass) and 50 % semitransparent algae photo bio reactor components. The transmittance of light trough the algae, depend on the season, and varies throughout the year. Having a lower light transmittance during summer and a high in winter, the panels are acting as an intelligent bio solar shading component as well, as energy producing. The Photo Bio Reactor panels requires sun light, water, and CO2, and in addition some nitrogen as a fertilizing agent. All these resources are available in the vicinity of Skt Kjelds Plads. The nitrogen in the form of NOx , and the CO2 comes from the motorized transport. Local rainwater is used for growing the algae.
Boosting the local economy, instead of large global corporations. The green algae has highly aestethic qualities, when used as a facade component.
H2 collection
cultivation of algae, the making a local renewable resource
It becomes a pollution collector absorbing the CO2 and NOx from the motorized transport in the neighbourhood of Sank Kjelds Plads. It releases H2 (Hydrogen) when it grows. H2 is a storable renewable energy source, that can be used in hydrogen fuel cells, providing a green non-polluting energy source that can be used in public transport, cars or feeding electricity into the local neighbourhood.
top of each other in the eco-garden towers. The eco-sustainable benefits for the city and neighbourhood for having an urban local food production and gardening are: The use of local resources: water, sunlight, fertilizer. Creating local jobs. Making local products which gives money back into the community. Helping to minimize the eco-footprint of the city, by growing local, freeing up resources in other countries for local production. Boosting the local community and identity and crating ownership and awareness, by cooperation around the urban gardens, feeding positivity into the green loop.
