Geometria_Autocostruzione_Prestazione: superfici sostenibili

Currently, in the international architectural context, complex shapes represent a support capable to allow interesting experiments aimed at the realization of sustainable shells. The purpose of this contribution is to identify a useful method to control the design of parametric surfaces through computation of technological solutions that improve the feasibility, maintainability and durability of results. Currently, this process is strongly favored by the development of computational tools based on user friendly visual scripting approach. These instruments facilitate the self-construction of the building product and allow to control the process from conception and design to manufacturing and assembly. Therefore, we think that the use of computational tools allows to enlarge the participatory dimension for the project of complex shapes. However, this approach requires a cultural refinement, generating organizational and technological knowledge. From research to practice, this approach is possible through the conscious collaboration of all the various figures involved within an integrated process for generating efficient and optimized systems from the constructive, economic and aesthetic point of view. The control of the shape and development of technologies are important to enable searching of integrated and innovative solutions, technologically sustainable and optimized. The contribution aims to highlight how the feasibility of complex shapes is related to the combination of strategies for the discretization of continuous with control of the entire system to encourage the creation of sustainable solutions. In particular, some representative cases allow to highlight the advancements developed in the current research area of the Architectural Geometry, and more precisely about paneling architectural free from surfaces topic. The research examines the issue of single curvature surfaces (developable surfaces), and shows how these surfaces are extremely convenient for the manufacture of complex surface. Hence, the purpose of this research is to obtain complex surfaces with zero or negative Gaussian curvature to break them down into elements developable: Digital Form Finding approach is useful to obtain interesting results. These surfaces allow to reduce production costs and facilitate the control of the manufacture and assembly phases. The collaboration between architects, engineers, mathematicians, computer scientists, educators and users can radically redefine the relationship between design and production: therefore, through a pedagogical activity, the aim is to generate a possible hierarchical system aimed to self-construction of the building product. Therefore, the purpose is to demonstrate how the geometry can be used as an analytical and planning tool, useful to integrate new forms and new materials in search of sustainable solutions and integrated approaches.
