summary The research focuses on the performative capacities of a pneumatic material system in regards to the specific environmental conditions. The use of Adaptation as a mechanism to modulate environmental performance was the main focus of the design process and research. The location of the sun during the day acts as a trigger to adapt the system, allowing the system to passively augment the environmental conditions. A new form-finding method that combines digital and material processes has been the main method by which the experiments were undertaken. This approach necessitates a dramatic shift in the architectural design, from producing static to environmentally responsive objects. It requires a shift in thinking from buildings as static and non-active systems to material system existing over time within specific environments capable of complex environmental performances.

summary Most foldable structures have been designed to optimize collapsibility and structural performance. Likewise, they have been solely applied to a limited number of architectural shapes such as arches, domes or geodesics. While the constant folding process between retracted and deployed states, has been the main concern of designers, non-constant transformations and the in-between states remains unexplored. This research will study non-constant transformations in the in-between states, with the aim to find novel shapes and extend the repertoire of current applications. Initially, existing structures will be modified in order to find what type of shape transformations can be produced. Finally, a novel solution, through a digital model and a kinetic physical prototype, will be proposed.

summary The delivery of a successful project demands high levels of collaboration across an expanded design team, which now includes consultants, fabricators and contractors as well as architects and engineers. The pace of development in design technology has been very rapid during the last few years and there are now many software products which offer high levels of sophistication. Most provide associative and parametric modelling strategies, which can be further enhanced and extended by the use of scripting languages. Designers are becoming tool-builders while fabricators are becoming digital craftsmen. With the advent of fast efficient drawing extraction the industry is at last making determined steps towards a model-driven process. However there is no integrated platform which supports the free exchange of ideas, combined with the evaluation of performance, experimentation with production techniques and the evolution of project-specific workflows. In education the design schools have been quick to recognise the potential of the new design technology. This has led to a rapid expansion in course curricula that now offer many new specialisations, most of which also need to be under-pinned by a good grounding in descriptive geometry, mathematics and physics. The architect as a generalist, who coordinates the work of specialists, is being challenged by an increasing breadth of technical studies that require more than just a superficial depth of understanding. In practice the gulf is widening even more rapidly. New graduates, who often have spectacular expertise in modelling and fluency in scripting languages, do not yet have the design and construction experience necessary to direct their efforts to best effect. On the other hand people running project teams do not have the technical background to understand the potential of the skills and resources that are available. Today there is no longer the continuity that used to derive from apprenticeship. As we experiment we find that tools based on new ideas and techniques can radically change workflow – but fear of the unknown can provoke resistance. So the problems we face in harnessing the new technology are as much social and cultural as they are technical. The presentation will focus on developing attitudes towards tool-building with the aim of integrating design, analysis and production. This is part of a continual and quite gradual process, which requires the ability to play interpretive roles that help to bring about cultural change. Examples will be shown from the work of the Specialist Modelling Group at Foster+Partners who now have tenyears experience in deploying design technology in an environment where research is intensely project driven.

title Digital Materiality: emergent computational fabrication
source Performative Ecologies in the Built Environment: Sustainability Research Accross Disciplines: 43rd Annual Conference of the Australian and New Zealand Architectural Science Association
summary Fundamentally architecture is a material-based practice that implies that making and the close engagement of materiality is intrinsic to design process. With the rapid uptake of new computational tools and fabrication techniques by the architectural profession there is potential for the connection between architecture and materiality to be diminished. Innovative digital technologies are redefining the relationship between design and construction encoding in the process new ways of thinking about architecture. A new archetype of sustainable architectural process is emerging, often cited as Digital Materialism. Advanced computational processes are moving digital toolsets away from a representational mode towards being integral to the design process. These methods are allowing complex design variables (material, fabrication, environment, etc.) to be interplayed within the design process, allowing an active relationship between performative criteria and design sustainability to be embedded within design methodology.

title Performative Wood: Integral Computational Design for Timber Constructions

summary Wood differs from most building materials in that it is a naturally grown biological tissue. Thus wood displays significant differentiation in its material makeup and structure as compared to most industrially produced, isotropic materials. Upon closer examination wood can be described as an anisotropic natural fiber system with different material characteristics and related behavior in different directions relative to the main grain orientation. Because of its differentiated internal capillary structure wood is also hygroscopic. It absorbs and releases moisture in exchange with the environment and these fluctuations cause differential dimensional changes. In architectural history the inherent heterogeneity of wood and the related more complex material characteristics have been mainly understood as a major deficiency by the related crafts, timber industry, engineers and architects alike. This paper will present an alternative design approach and associated computational design tools that aim at understanding wood’s differentiated material make up as its major capacity rather than a deficiency. Along two design experiments the related research on an integral computational design approach towards unfolding wood’s intrinsic material characteristics and performative capacity will be discussed. The first experiment explores the anisotropic characteristics of wood by exploiting the differential bending behavior in relation to the local induction of forces through which a specific overall morphology can be achieved. The second experiment focuses on the hygroscopic property of wood as the base for developing a surface structure that responds to changes in relative humidity with no need for any additional electronic or mechanical control.

title Parametrics of Movable Polyhedral Models in Performative Architecture
doi https://doi.org/10.52842/conf.caadria.2009.185
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 185-194
summary We present a parametrical approach to movable polyhedral models. Based on polyhedral geometry the whole structure consisting of an interconnected series of prisms (with dual spherical joints) can move 3-dimensionally. The principles of polyhedral geometry allow constraint movements of the prisms with a certain degree of freedom. We use these geometrical principles to open and close façades for ventilation or structures for shading control superimposed on building envelopes. The different groups of regular polyhedra in the Euclidean 3-space and their specific topological types will be discussed in order to choose the appropriate model and showe geometrical theory of movable polyhedral models can be successfully applied to performative architecture.

summary The use of a design tool materializing the performative design concept is presented. The association of parametric design with lighting intentions leads to a light-based parametric design approach. This approach have been implemented through an inverse natural lighting model which is intended to aid the daylight design (windows, shading devices or others) in the early stages of architectural design. We show this model can be used in a performative design approach to define the transparency property through a case study: the dome of the Louvre Abu Dhabi museum by Ateliers Jean Nouvel.

title Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

summary For sustainable building design, computational tools, mostly in the form of simulations, are employed to determine loads and to predict systems performance typically in terms of energy use. Currently, sustainability, in the building domain, is judged by a rating system. Design choices are validated, by measuring against one. The objective of the framework is to provide a general approach to processing the informational needs of any rating system, by identifying, categorizing and organizing relevant data requirements. Aspects of sustainability that designers deal with intuitively will have a structured guideline and gauge as one selects a rating system of choice.

summary Computer-Aided Design (CAD) has become more and more part of the common architectural practice. Some designers have explored (in the past) different aspects, especially formal ones, allowed by these new information technologies. This paper’s goal is to explore the invention that would be specific to this new architectural practice. The hypothesis is to go back to the specificity of the image and to examine its evolution. This analysis will be done with reference to the « cycle of images » of the French philosopher Gilbert Simondon, described by means of stages and levels. This particular way of thinking will allow us, besides an overview of all those images in a genetic diagram, to reveal what can enable the passage from one level to another. We call this : “invention”.

summary The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

summary This paper compares the musical and architectural languages exploring the similarities between works related to Twelve-tone music and Descontruction. To do this, first looks at Opus 27 by Anton Webern whose goal was to explore the spatiality in the context of sound perception by using a topology based on a square matrix of twelve rows and columns. Next, compares these procedures to those adopted by Peter Eisenman to design the conceptual model Guardiola House (1988), demonstrating the affinity between spatial and temporal constructions in the works of these two authors.

summary This article presents the current state of an ongoing research project developed at the ARIAM-LAREA laboratory of the school of Paris La Villette. The aim of this research is to offer architects digital tools that allow them to explore the project with freehand sketches as they do with pencil and paper. The role of these tools is to interpret the freehand sketches in order to work on them and transform them. They produce from these freehand sketches a digital model from which it will be possible to build a 3D representation, or to evaluate the project from any technical point of view. This paper only shows the part of the system that recognizes particular strokes in an architectural drawing.

summary Widespread use by 3D designers of simple digital modeling applications such as Google’s SketchUp may displace the use of physical models in design. However, the difficulties often faced by non-experts in the ad hoc navigation of digital models during design reviews have not been eliminated. Keyboards and mice are clumsy navigational devices and difficult to share in a collaborative setting. This work explores the combination of new, inexpensive interface hardware technologies with a popular 3D modeler in order to create a viable surrogate for physical models. Two architectural model navigation and presentation interfaces were developed, one based on an Inertial Measurement Unit (IMU) circuit board (“Gizmo”), and one that used a Wii Remote Controller (“WiiView”). Both were interfaced with the popular architectural modeling program SketchUp. Anecdotal responses and preliminary user testing results are presented.

summary The demand for up-to-date information and design ‘tools’ to help architects design more sustainable buildings is rapidly expanding. This demand has led to use various ecological assessment tools as support tools for the design process. The absence of adequate tools, which contribute to early stages, as well as the additional costs of tardy modifications, has led us to propose an eco-design support tool. This tool is based on a methodology named “Eco-Model (EM) Method” that focuses on the ecological approaches of a building. This method proposes to consider environmental friendly solutions from the first sketches by proposing a number of micro-solutions, called here Eco-Model or “EM”. Subsequently, the study presents the first contour of software based on an EM approach. Thus, the various actors of the design team will be able to browse the useful information for their green projects and so collaborate to optimize the building design.

summary In this paper, we suggest a generic city description model suited for purposes like semi-automatic city modeling and urban layout evaluation. The generic city model refers to basic vital functions of a (computable) city. Feature patterns are used to extend the generic city model with global and local characteristics. The Hellenistic cities serve as a platform for a first implementation to test a semi-automatic city model generation. As a result four cities are reconstructed as a first example of our ongoing work, Miletus, Knidos, Priene and Olynthus. Future work will deal with the application of the generic city model to the performance simulation of contemporary urban layouts.

summary The paper outlines the relevance of computational geometry within the design and production process of architecture. Based on the case study “Twister”, the digital chain - from the initial form-finding to the final realization of spatial concepts - is discussed in relation to geometric principles. The association with the fascinating complexity, which can be found in nature and its underlying geometry was the starting point for the project presented in the paper. The translation of geometric principles into a three-dimensional digital design model was followed by a process of transformation and optimization of the initial shape, that integrated aesthetic, spatial and structural qualities as well as aspects of material properties and conditions of production.

summary Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problembased learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.
