Breivoll during winter
BACKGROUND Oslo will be an applicant for hosting the winter olympic games in 2022. In light of this, Kjelsrud in Alna city district in Groruddalen has been selected by Oslo municipality as one of two possible sites suitable for building the olympic village. It has been named as the most risky option, but also as the site with the most potential for improvment. The keyword here is legacy. What happens after the games is what is the most important. Today Kjelsrud is a very problematic site. Most of its area is in use by either industry or important infrastructure like highways, local roads and railroad. The microclimatic conditions are bad, both the air, water and the soil is polluted after decades of industrial use and being the location of dumpsites. It is a place for the car, not for the human being. As Oslo is the fastest growing city in Europe, it is natural to think of Kjelsruds future as being a part of the urban city. But if Kjelsrud is to be a livable place in the future, a lot has to change. My goal is to design Kjelsrud for the future, and to change some fundamental elements. Kjelsrud has become a wrinkly old man, and this project attempts to rejuvenate him.

MAPPING SUMMARY
Infrastructure
Scattered green structure
Missing waterlink
Industrial use
The E6 highway is of high importance in this area. So is the railroad with the Alnabru terminal. Strømsvegen is an mportant local road along the valley, and Nedre Kalbakkvei provides an important local cross-connection.
The green structure in this area is scattered at seemingly random spots, except along the open parts of the Alna river.
The Alna river is in pipes underneath the Alnabru terminal.
A very high percentage of the area in Kjelsrud is in use for industry.
Topographic landscape
Cold air flow
Air pollution
Air stagnation zone
The landscape in Grorudalen is declining in a southwest direction. The moraine crossing the valley on Alfaset is an important part of this landscape, greatly affecting the microclimate in Alna.
The Alfaset moraine is blocking and redirecting the cold air flowing down the valley and from the hillside on quiet days. The cold air flows down the Alna river valley.
Strømsvegen is creating moderate air pollution, while the E6 highway is creating heavily poluted air.
This mapping of overlapping systems of landscape shape and aerial quality shows that the cold air flow stagnates over Kjelsrud. This creates a cold, humid and polluted air quality that is not recommended for habitability.

COLD AIR FLOW Experimentation in model By pouring steam created by dry ice through a model with exaggerated elevations, I investigated the impact of the terrain and built structures on the cold air flow. It was evident that the steam in a large degree stagnated on Kjelsrud because of the glacial moraine. I experimented by implementing different housing structures, but it did not have a big impact on the flow of the steam. What had a big impact was altering the terrain. By lowering parts of the Alfaset moraine south of Kjelsrud, the steam could flow freely on both sides of Alfaset.

BREIVOLL COLD AIR DRAINAGE AND FILTER PARK
Old landscape, 1 meter contours
New landscape, 1 meter contours
A bluegreen connection Today the Alna river is in pipes beneath the Alnabru terminal, and the green structure is disconnected along the valley bottom. This project creates a link between the disconnected parts of this bluegreen structure. This can function as a new main touring path along the valley.

BREIVOLL DRAINAGE PARK AND BRIDGE
Cleaned air
Polluted air
Vegetation filter The cold air flow will be polluted, primarily by the E6 going by the park. It is therefore vital to have a layer of vegetation to absorb gases like CO2 from the airflow, releasing cleaner air in the bottom of the park. A mix of evergreen and desidous trees native to the Oslo area will ensure a filtering effect all year around. While the cold air effect is usually most severe during the winter, and the soil may be quite moist in this area, a majority of spruce.

Pedestrian and bicycle path system Today, the pedestrian pathway along the Alna river is ending at Nedre Kalbakkvei by the Alnabru cargoterminal. This new development creates a link in the green structure as well as the path system, providing another step in the way of creating a connected pedestrian and bicycle path along the vally bottom.

HOUSING STRUCTURE: Building Kjelsrud for the future The city of Oslo is the fastest growing city in Europe, and the city is expanding. Because of the strict Marka borders, we can not expand more hosizontaly. The solution has to be densification. Therefore it is reasonable to think of the future of Kjelsrud as being a part of the inner urban Oslo. Pilestredet park has been my inspiration for a good city development and is a part of the city I think creates high quality, dynamic spaces in the city. An a bit more suburban version of this structure is what I have been aiming for, and think can work both in short- and longterm in Kjelsrud.
approximately
60m²
per apartment
The apartments structure is layed out so that there are windows on both sides of the building, granting each apartment sunlight at most times of the day. On the first floor, the hallway will also have access to both sides of the building. After the olympics, some apartments can be merged, to make familysize apartments.
