Architectural facades throughout the history have been designed to respond to environmental, social and functional conditions among other considerations. Advancements in Digital Design Computation (DDC) emerged as an essential support for exploring and creating contemporary architectural facades. Current research attempts seeking responsive kinetic facade revealed different methods of integrating kinetics into the physical facade. However, some case studies indicated that physical façades struggled to achieve the anticipated kinetic responses after a facade is constructed. In addition, the process is formal, prescribed, lacks flexibility and can only assist the designer in the visualization of the design. As a consequence, the challenges in understanding the process of connectivity between digital/physical kinetics are important to address in the early design stage. Digital and physical façade prototypes would allow designers to test the qualities of such system before constructing full-size mock-ups and discover new modes of parametric design thinking in architecture. In this work, we report on an ongoing development of a custom Add-on utilizing Autodesk ® Revit application that connects between the kinetic properties of the digital and physical model to control dynamic façade. We deployed the Revit Application Programming Interface (API) C# programming to manipulate the kinetic response through linear actuation. The system framework proposes a practical mechanism connecting solar exposure values to a Building Information Model (BIM). In this process, an Arduino Mega board, servo motors, tooth-beam and tensile-fabric material were used to construct the small physical prototype and program its automation. While adding to previous research, we are tackling three challenges. The first is to dynamically harness the response mechanism of kinetic façade so that to avoid uninformed design decision making. The second is to map the digital/physical kinetic properties in terms of: modeling, process and function. The third is to assess the benefits from our approach of connecting BIM parametric model with physical prototypes. Our experimental project demonstrates how data could be transformed digital/physical façade model. We conclude by observations from this work on how BIM parametric modeling with design computation could influence the future direction of kinetic façade systems.

The word rapid prototyping (RP) was first used in mechanical engineering field in the early 1980s to describe the act of producing a prototype, a unique product, the first product, or a reference model. In the past, prototypes were handmade by sculpting or casting, and their fabrication demanded a long time. Any and every prototype should undergo evaluation, correction of defects, and approval before the beginning of its mass or large scale production. Prototypes may also be used for specific or restricted purposes, in which case they are usually called a preseries model. With the development of information technology, three-dimensional models can be devised and built based on virtual prototypes. Computers can now be used to create accurately detailed projects that can be assessed from different perspectives in a process known as computer aided design (CAD). To materialize virtual objects using CAD, a computer aided manufacture (CAM) process has been developed. To transform a virtual file into a real object, CAM operates using a machine connected to a computer, similar to a printer or peripheral device. In 1987, Brix and Lambrecht used, for the first time, a prototype in health care. It was a three-dimensional model manufactured using a computer numerical control device, a type of machine that was the predecessor of RP. In 1991, human anatomy models produced with a technology called stereolithography were first used in a maxillofacial surgery clinic in Viena.

The fuzzy front in product development is frequently mentioned as the most critical phase of the innovation process, and the five cases of successful design innovations here indicate that experiments and an experimental approach are generating positive outcomes. The experiments in the cases can be characterised as various forms of prototyping. Interestingly the prototyping and experiments took place in the very early phases of the innovation process, rather than later as often advised and interestingly experimentation in the cases here appears to be a vehicle for creating new options. Furthermore, the analysis demonstrates that prototyping can be considered as a punctuation device, as it offers those involved the option of opting out of ongoing processes, routines and engage in playful behaviour by allowing for a freer experimentation with materials, processes, methods to challenge existing knowledge and explore potential solutions. In science, by contrast, experimentation generally is carried out to support, refute, or validate a hypothesis, in other words it seems to be associated with testing options rather than creating them.

This paper presents some results of an ongoing interdisciplinary research about models and prototypes of biomimetic devices via installations and the focus of this paper is to outline this research role in architectural purposes as it perpasses the cultural and heritage contexts by being a way of understanding and living in the world as well as taking place in the world as devices or environments that pass on to future generations to use, learn from and be inspired by. Both the theoretical and the experimental work done so far point out that installations built with association of laser cutting and rapid prototyping techniques might be on the best feasible ways for developing and testing new technologies involved in biomimetic devices to architectural purposes that put both tectonics and nature as their central theme.
