Prototype #1


Prototype # 1 - Wind // Sun // Structure

Intension: The intension of the prototype is to create a space where the wind is experienced visually and not physically. This is to be done by leading the wind over the structure by angling the layers of the membrane. By using a soft material like latex the membrane is flexible and it will flutter in the wind and thereby affect the shadows created by the filtering of light. In relation to the sun the purpose of the prototype is to layer the membranes so that the light will be filtered through several layers of both the same type of material; latex on the one side and different materials; perforated cardboard and latex on the other side. This will create different light conditions that will be tested.

Conclusion: This prototype focused on wind and sunlight from East and West. When subjecting the model to wind of different speeds, the angle of the surfaces led the wind upwards and around the structure. When increasing the wind speed the materials of the model acted differently; it was very visible in the latex where the material is more or less stretched out. When the latex is tight it is less vibrating than the places where it less stretched out. The perforated material moves a lot, however, it is a movement of the entire surface at once and the vibrations of the wind are not visible in the same way as the latex, which is more wavy.� the perforated cardboard moved in one direction at a time, because of the stiffness of the material. According to the sunlight the test showed that the thick and thin latex created the intensity of the shadow; it was not to see on the floor if it was the thick or thin latex filtering the light. The layers did not create different light situations on the floor as expected. However, the layers were casting shadows on each other revealing the composition of the structure. On the East side of the model the sunlight is filtered through the perforated cardboard which creates a shadow pattern on the lower mebrane of latex. These shadows differ in sharpness according to the distance between the two membranes. When the wind interacts with the materials the shadows move along with the membranes and makes the wind visible.


Prototype # 1 - Wind data

The wind diagrams are to be understood as an illustration of how the wind intensity is spread in the different directions. From this it is possible to read exactly where the wind is the strongest during the year.
