Project: Design of an innovative facade element Tutor: Peter van Swieten, Marcel Bilow In collaboration with: Tom Bouwhuis
The Bucky Lab Studio is a project where the combination between architecture and building technology is brought to a higher level. The assignment is to design an innovative and sustainable facade element / concept for a high rise building application, which will be later materialized and developed to the level of a final design. THE RESEARCH The project’s research integrates Computer Aided Design and Modelling (CAD & CAM), structural analysis, material sciences and technological research in the design process. The research is done by virtual and physical testing the design’s materials and structural performance. The results are used as feedback to optimize the design into a state that it can be finally build as a prototype. THE PROTOTYPE The final test is the realization of a full scale prototype or a part of the final design. The design is translated into working drawings, material quantities and a production strategy as a preparation for the actual building.

of an interactive and adaptable element that can create movement according to the different environmental conditions in which it is exposed. The concept is based on the research about how buildings can sense, feel and observe the environment and react to it and how these reactions become perceptible by the users of the buildings.
The right exploitation of the sun during sunny days and the prevention at the same time of unwanted solar radiation can lead to a more sustainable architecture and a better controlled indoor climate. So the façade research was based on the development of a moving sunshade element. As the façade element should function independently from the building and should also be able to be adjusted to more than one building, a second skin structure is chosen to be designed. The element will interact to the sun by controlling the amount of sunlight that will enter the building. A sunshade panel has been designed, that can take specific steps in order to block the sun radiation when is not needed. The sunshade can move according to the inclination of the sun, forced by a solar sensor that will be attached to it. In this way it will prevent the direct light when the sun’s rays are nearly horizontal (during winter months) and will serve as a light shelf reflecting light to the interior of the building when it is needed.

The walking sunshade is a solar panel than can walk over any curtain wall facade without restrictions, thus providing shade where needed, while supplying its own energy demands.
This walking shading element offers a solution for a problem that occurs with virtually any contemporary office facade, which is usually made of glass and therefore needs shading.
It is triggered by a solar sensor, and able to move horizontally and vertically and to orientate towards the sun by using three extendable arms, each of which is powered by an individual motor. Each arm is connected or disconnected from the facade by means of suction cups. The result is a spectacular, dynamic facade.
This element can provide that in an architecturally interesting way. Because of the complexity of the design not every aspect of it has been worked out completely, mostly as a result of financial limitations. The project does however describe a framework for the development of a real walking sunshade.
