Prototype #2

Prototype # 2 - Wind // Sun // Structure

Intension: The intension of this prototype is to shape the form out of the interaction between the structure and the phenomena. We have concrete data for both wind and sunlight here in Aarhus, which we will use to form the structure. A focus concerning the sun is to keep out the intense summer light and get the most out of the winter sunlight. The wind intensity is the other focus in this prototype. We want to protect the inner core of the structure from the strong wind here in Aarhus. To prevent to much forces against the walls towards the strong wind, we have to consider the angle of the walls.

Conclusion: In this model we have focused on the east side of the structure and tested wind and sun in relation to the structure from this direction. With so many wind screening membranes, there is a lot of wires that is crossing over the inner core. This makes it hard to fit the sun screening membranes between all the wires. The angle of the wind screening membranes defines the hight of the pillars. The pillars length is therefore relative high in relation to the rest of the structure. The wires from the pillars shapes a new open but confined space which we did not anticipate beforehand. Wind: The intension of this prototype was among other aspects to screen the inner core from the wind from east. By mapping the wind directions in relation to the inner core, we could map where to put the wind screening membranes to prevent direct wind into the inner core (see page 22). The 45* angle of the membranes leads the wind over the structure simultaneously as it allow people to stand up inside the structure. In the video with semolina we can se that the wind screening membranes is working. What we discovered though, was that the photo wall behind the structure affected the wind and leaded the wind in to the inner core. This shows us that context is very important when we are dealing with wind. At the structure itself we can see that the looser the wires are, the more freely the membranes are moving. This can be a benefit if we want to enhance the wind visually, but it makes the structure more vulnerable in relation to the wind intensity. The latex is working as a full screening from the light and not as a filter. If we want to filter the light trough different layers, we should use another material. Though, the latex is an excellent screen for shadows to hit. The transparent wind screening membranes reflect light back out.
