title The Return of Nature as an Operative Model: Decoding of Material Properties as Generative Inputs to the Form-Making Process
source International Journal of Architectural Computing vol. 11 - no. 2, 267-284
summary The abandonment of nature as an architectural model and the redefinition of the relationship between form and material were two of the main consequences of industrialization for modern architecture. While nature was replaced by the machine as a model for architecture, industrial production suppressed the craftsman's knowledge of the material and the associated techniques once essential to the form-making process. Thus, the replacement of nature as a model implied that principles once related to natural processes started to be seen as industrial values, i.e., the economy of means stopped being recognized as a quality related to natural form-making processes and became a demand of industrial production. Nowadays, material properties and nature are being reintroduced into architecture with the help of digital technologies; that is, the return of nature though computation. As a result, nature has become an operational model as opposed to the visual or iconic one it used to be; its inner qualities and processes are being decoded in order to inform the form-making process and foster innovative digital ornamentation.

summary Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.

summary Visual rules are powerful in loosely capturing the impact of material behavior on form in designer’s hands-on experimentation. They present a first step to translate the causal relations between material and form to computation without sacrificing the uncertainties in the designer’s interaction with the materials. This study investigates how to model the relation between material and form with visual rules so that the model embodies some of the phenomenological aspects of reality, rather than merely reproducing it.

summary Spatial configurations can be perceived through a variety of descriptions of their physical form and structure. Each description can offer an autonomous interpretation or be combined with others parathetically, in a logic of multiple distinct layers. However it is asserted that meaningful information can be extracted from a simultaneous view of sets of descriptions within a high-dimensional structure. This paper investigates the possibility of conducting a comparative analysis and classification of non-typical spatial formations based on the synchronous view of multiple quantifiable spatial attributes. Under the hypothesis of a reciprocal definition of spatial structure and occupation practices, it is intended to identify distinct generic spatial types in order to subsequently determine a range of suitable respective generic use types. This investigation supports the formulation of strategies for the reactivation of unused, residual urban voids, currently being addressed by the research programme titled "Strategies to network urban interventions in the Metropolitan Centre of Athens". The programme is carried out by the School of Architecture of the National Technical University of Athens in collaboration with the Region of Attica, under the scientific coordination of Professor Dr. Parmenidis (2013).

summary Since the almost simultaneous publication of Kevin Lynch and Jane Jacobs´ seminal and pioneer urban manifestos, the discipline has been increasingly permeated by what could be rightly called the phenomenological impulse. While sharing methodological principles, however, they represent two very distinct approaches to the study of urban matters, a distinction rooted on their chosen object of study. The drawing of this distinction constitutes this research´s point of departure. Its fundamental aim is to help further the development of what we characterize as the Jacobs´s lineage of urban thought. To this end, the paper outlines methodological rudiments for the development of a methodological tool that would allow the beginning of a systematic study of the patterns of people´s presence and absence in urban space (streets). We call it Urban Polaroid. This work is part of a government funded (fondecyt 11110450) project.

summary Agent-based systems have been widely investigated in simulation and modeling. In this paper, it is proposed that agent-based systems can also be developed as generative systems, in which different aspects of performative design can be defined as separate drivers in a proper computational framework. In this manner constrained generating procedures (CGP’s) are studied to integrate the discrete design processes into one system. Subsequently, this generative agent-based design tool is accompanied with generating and constraining mechanism which are informed by material characteristics and fabrication constraints, bringing to the forefront emergent complexity.

summary We present and discuss a didactic for augmenting architectural design education with computational design techniques via integrative feedback loops and show examples of student projects. Our goal is to embed new technical skills into existing design abilities as quickly as possible, in order to enable our students to exploit and explore the extended capabilities of digital design techniques within the framework of architectural design projects. We instigate a process of continuous mutual feedback between different fields: on the one hand between technique-based exercises and design-related steps, and on the other hand between the digital and the physical. Through oscillation and feedback, the newly learned skills are directly interwoven with the existing ones. Special emphasis is put on the illuminative effects of transitions between different media and on issues of fabrication.

summary A shape grammar was developed for analyzing the evolution of Maputo´s slums with the strategic objective of capturing the evolution of house types and understanding the social agreements behind the spatial relations of their house elementary spaces in order to reuse such rules for the purpose of rehabilitation. This paper shows preliminary results of the research and aims at developing, based on the resulting grammars, a parametric tool able to execute morphological analyses, simulations and generate improved design solutions for the qualification of Maputo´s informal settlements.

source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 2, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 345-353
summary A method for quantifying ambient surveillance is presented, which is based on probabilistic-possibilistic perception. The human surveillance of a scene through observing camera sensed images on a monitor is modeled in three steps. First immersion of the observer is simulated by modeling perception of the scene from the camera locations using probabilistic perception approach. The perceptions are thereafter combined by means of probabilistic union, simulating simultaneous watching of the scene from multiple viewing positions. As third step the combined perceptions are converted to a possibility using triangular possibility density function. The latter step accounts for the fact that surveillance takes place via monitor depiction and not directly as perception of the actual physical scene. The method is described and demonstrated by means of an ambient surveillance application involving three cameras. The resulting possibility of perception is compared to the case of using two cameras, quantifying the added value of additional camera as to surveillance.

summary Academic Libraries (ALs) design concept has been under a changing process, precipitated by both internal needs and external pressures including changes in the societal context of education, the information services and documentation storage requirements. This paper is focused on a model of form and function to assess AL’ in use, in order to explore ways for better understanding their performance. The proposed model was developed within the scope of a wider research project and makes both use of Post-Occupancy Evaluation and of Space Syntax procedures in order to explore how the spatial configuration influences the performance and use of ALs space. It considers ALs building typology as spatial, physical and social systems, by: 1) measuring users satisfaction about how well the space supports their requirements; and 2) providing information on how architecture and spatial design support - enable and generate - flows of information, communication and knowledge.The analysis provides evidence suggesting that ALs’ spatial system influences study performance, patterns of use and co-presence of its users. The results of data inputs point out prospective strategies about space intervention.

summary This paper proposes an architectural system interactive to both users and the environmental condition in real-time. While nature acts as a global control for the system, the user can alter it locally. Due to the increasing digitization of our contemporary culture, there is an unprecedented capacity for information to flow in our physical and socially net-worked world that can be used to inform design problems and processes. Live and real-time information sources, like Twitter, could be virtually scanned for specific data input associated to a par-ticular geometrical manipulation. This process enables a collective group of users to inform the system. As the number of users increases there is collaboration for defining the form which is different from single user interaction. Since the model is associated with a specific definition of generative behaviours as described by the words, these definitions could be used as the

summary This work is a research on the application of genetic algorithms (GA) to urban growth taking into account the optimization of solar envelope and sunlight in open spaces.It was considered a typical block of a Spanish grid, which is the most common subdivision of the urban land in towns situated in Argentina. Two models are compared, one in which the growth has no more limitations than building codes. The other one, in which the growth incorporates the solar radiation as a desirable parameter.This way of parameterizing configures a bottom-up method of urban growth. No top-down decisions intervenes in the growth process.This tool proves to be useful at early stages of urban planning when decisions—which will influence along the development of the city for a long time—are taken.

summary Mass customization is pointed as a means of improving a company’s competitiveness, which is an essential trait in Europe’s economic situation of today. This paper reports a mockup implementation of the mass customization paradigm to ceramic tableware design, through the use of shape grammars, parametric modelling and rapid prototyping. Focus is emphasized on the initial development of a parametric shape grammar as a design system, operating on curved surfaces and solids. Mapping operations are suggested for dealing with the formal complexity of these shapes. This initial academic experiment poses as a first step into the development of a mass customization system that is expected to meet industry standards.

summary Industrial robots controlled by parametric design software and visual programming environments are gaining popularity in the research and use of non-conventional construction processes in architecture. Process automation which can be personalized through variable components promises to become an industry standard with similar cost structures to current pre-fabrication industrial processes. In order to incorporate competencies from non-serial variable architectural modular design, an initial teaching initiative (Advanced Architectural Design Studio – USM) was developed in Latin América. The strategy employed is based on incorporating concepts and instruments of Construction & Design Automation for CAD/CAM processes with a Six Axis Robotic Arm (KUKA KR125/2).

summary A method for fusion of perceptions is presented. It is based on probabilistic treatment of perception, where perception quantifies the chance an unbiased observer sees an environmental object, and the associated probability can be interpreted as degree of awareness for the object. The approach uniquely accounts for the fact that final realization or remembrance of a scene in the brain may be absent or elusive, so that it is subject to probabilistic considerations. For objects that are to be perceived from multiple viewpoints, such as a sculpture in a museum, or a building in its urban context, the probabilistic approach uniquely defines the fusion of perceptions. This is accomplished by carrying out the probabilistic union of events. The computation is presented together with its geometric implications, which become rather intricate for multiple observers, whereas the computation is straight forward. The method is exemplified for two applications in architectural design at different scales, namely interior and urban design, indicating the generic nature as well as the large application potential of the method.

summary This study was accomplished in the context of a broader research to be developed in an ongoing PhD program in architecture. The purpose of this study is to give a perspective of the research progress and to present a shape grammar simplification that will be improved to assist the rehabilitation design process of the bourgeois house of Oporto.The typology of the bourgeois house of Oporto, built from the late sixteenth century until the early twentieth century, is dominant in the ancient fabric of the city and in need of rehabilitation. From the analysis of a representative sample of a moment of its evolution, it is possible to verify patterns and to define rules.This first approach intends to validate the use of shape grammars as a tool, able to assist the architect in the rehabilitation design process of the bourgeois house of Oporto.

summary This paper focuses on the implementation of a computational design and robotic fabrication method that integrates the elastic and hygroscopic behavior of wood as active drivers in the design process, using the material’s differentiated characteristics as its main capacity. The project builds on previous work by the authors, furthering their research on the formal and performative transfer of such behaviors into informed architectural systems. Wood’s fibrous structure, relatively low stiffness and high structural capacity are instrumentalized into self-forming mechanisms through conical elastic deformation, while the same organic makeup and corresponding hygroscopic properties have also been programmed, formally articulated and integrated into a climate responsive architectural system. This research will be presented alongside a full-scale architectural project (Figure 1, Figure 2).
