Towards A Bottom-Up Design Approach

Abstract This paper aims to investigate the importance of pneumatic structures in the responsive architectural design field. The main objective is to identify how pneumatic structures were addressed through Frei Otto’s vision of experimentation leading to successful architectural examples. Other examples, such as the Veech Media Architects installation in the Latent Utopia Exhibition is mentioned to show a different application of pneumatics as an experiential project which is digitally designed. Finally, this paper questions if a visionary project like “city in the arctic” could be built using the bottom-up design approach of design. The paper clearly explains how this bottom-up design approach could impact the responsive architecture field and hence create a “Responsive Pneumatic Utopia.”

What makes it an innovative field of research is “air”, which is the most dynamic form of matter, controlling the structure. Hence, this paper aims to research the fundamentals of pneumatic architecture and identify how it could be applied in the field of responsive architecture. It also aims to test the validity of pneumatic structures in the field of responsive architecture first, through identifying their adaptive characteristics. These characteristics will define a stronger vision for the pneumatic structures other than Tweedie, Andrew. Atmosfields.1970.

Air is the most dynamic form of matter and this provides great potential for research in the architecture field.

The image shown is interesting because it shows how lightweight pneumatic structures are. It also shows an apparent comparison between the rigid structures in the background and simple a pneumatic structure floating on water.

he wasn’t satisfied with the “architect’s traditional role”. He also adds that Otto’s design process was a search for the most optimum form through his experimentation. (70). Hence, it is fundamental to grasp his material experimentation process. Otto classified pneumatic structures similar to tents, with the only difference of the absence of the pole support.

Hence, architects should realize the importance of designing pneumatics through the bottom-up approach of design, as previously stated. It is essential for the pneumatic structures to be explored further by architects and more specifically in the field of responsive architecture. Architects of our current era must be able to utilize the technology and the tools being available to them and think of new design methodologies.
