title	Methodological Approach for the Integration of Material Information and Performance in the Design Computation for Tension-Active Architectural Systems
doi	https://doi.org/10.52842/conf.ecaade.2011.799

summary	As computational design processes have moved from representation to simulation, the focus has shifted towards advanced integration of performance as a form defining measure. Performance, though, is often assessed purely on the level of geometry and stratified between hierarchically independent layers. When looking at tension-active membrane systems, performance is integrated across multiple levels and with only the membrane material itself, defining the structural, spatial and atmospheric qualities. The research described in this paper investigates the integrative nature of this type of lightweight structure and proposes methodologies for generating highly articulated and differentiated systems. As material is a critical component, the research focuses on a system-based approach which places priority on the inclusion of material research and parameterization into a behavior-based computational process.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
doi	https://doi.org/10.52842/conf.acadia.2011.082
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

title	Integrative Design Computation: Integrating material behaviour and robotic manufacturing processes in computational design for performative wood constructions
doi	https://doi.org/10.52842/conf.acadia.2011.072
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 72-81
summary	In contrast to most other building materials, wood is a naturally grown biological tissue. Today, the organic nature of wood is recognized as a major advantage. Wood is one of the very few naturally renewable, fully recyclable, extremely energy efficient and CO2-positive construction materials. On the other hand, compared to industrially produced, isotropic materials, the inherent heterogeneity and differentiated material makeup of wood’s anatomic structure is still considered problematic by architects and engineers alike. This is due to the fact that, even today, most design tools employed in architecture are still incapable of integrating and thus instrumentalizing the material properties and related complex behavior of wood. The research presented in this paper focuses on the development of a computational design approach that is based on the integration of material properties and characteristics. Understanding wood as a natural composite system of cellulose fibers embedded in a lignin and hemicelluloses matrix characterized by relatively high strain at failure, that is high load-bearing capacity with relatively low stiffness, the particular focus of this paper is the investigation of how the bending behavior of wood can become a generative design driver in such computational processes. In combination with the additional integration of the possibilities and constraints of robotic manufacturing processes, this enables the design and production of truly material-specific and highly performative wood architecture. The paper will provide a detailed explanation of such an integrative approach to design computation and the related methods and techniques. This is complemented by the description of three specific research projects, which were conducted as part of the overall research and all resulted in full scale prototype structures. The research projects demonstrate different approaches to the computational design integration of material behavior and robotic manufacturing constraints. Based on a solution space defined by the material itself, this enables novel ways of computationally deriving both material-specific gestalt and performative capacity of one of the oldest construction materials we have.

title	Heavy Design
source	International Journal of Architectural Computing vol. 9 - no. 3, 251-258
summary	Digital tools in architecture have a powerful capability that we have only begun to explore; the questions to ask of them are perhaps not what they can do but what should we use them for? To date, much of the work done in the area of computational design has been used as elaborate patterning - some have called it ‘ornament’. The significance of this ornament is not only pleasure but in its use of digital patterns to represent our current complex and digital age.This representation in itself is not problematic; however, what is problematic is the lack of other meaningful uses of the digital form-generating tools and their distance from a culture of making. The main failing of our use of digital design (algorithmic or not) in architecture to this point is its inability to translate smoothly from the digital world to the physical world. The main reasons for this difficulty in translation are gravity and inherent material properties. Working with gravity and its physical implications is generally considered the role of the structural engineer; as such, engineers have generally created digital tools in this area.The engineer's methodology analyses a structure based on complex structural analysis programming but in order to do this, a detailed description of the structure must already exist. This is not useful in preliminary stages of design. However, the generation of architecture within an environment, which already includes structural principles, may bring us one step closer to this transition of virtual to physical by including gravity in architectural generation while not diminishing the creative form-generating process. An approach has been proposed which responds with a concept of ‘heavy design’. This type of approach incorporates logics from other disciplines, primarily structural engineering, to inform design. The design process incorporates the structural behavior of a system into the architectural model. Engineering offers a mathematical interpretation of the physical world and this is inherently suited to algorithmic design because it is already in equation form. It can thus be programmed into the architectural form generational software. The variables used in the equations become the variables within the architectural design and this inherently brings the natural physical laws to the architecture through a numerical, algorithmic method. The design produced is not a singular answer but rather a responsive vocabulary of a structural system, which is then employed in design in differing conditions. The architecture produced is both function and ornament, having cultural interpretation but carrying out many engineering tasks: a true parametric architecture.

title	Tetrahedron Cloud
doi	https://doi.org/10.52842/conf.acadia.2011.284
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 284-291
summary	The research project, tetrahedron cloud, explores agent-based stochastic behavior as a design tool. It investigates the possibilities for producing volumetric tetrahedral meshes based on the interactions of individual stochastic agents. The research situates itself at the intersection of the visual arts, the physical sciences, and computer science. The basic interest in stochastics comes from the visual arts; the growth simulation approach is borrowed from the natural sciences; and the use of a tetrahedral mesh within C++ comes from computer science. But more generally, the project focuses on architecture’s ongoing engagement with stochastic systems. By embedding extremely specific tendencies within an agent’s behavior, while also allowing for stochastic variation, we can create larger systems that are both in and out of our “control”. This sidesteps the typical limitations of many computational geometry and parametric methods, where there is often an overly deterministic relationship between the input and output of a given system. Such a shift from optimization to behavior inevitably brings up troubling questions of style. Abandoning the search for a “best” solution, or even the articulation of the criteria for such a task, re-opens computational architecture at its deepest levels as a site for design speculation.

title	Towards morphogenetic assemblies: Evolving performance within component-based structures
doi	https://doi.org/10.52842/conf.caadria.2011.515
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 515-524
summary	Performative design can be understood as the combined usage of spatial analysis simulations and form generation procedures to imbue architectural form with material characteristics and behaviours which define desirable structural, environmental and economic performance. However, to date, design processes that facilitate the integration of ‘form generation’ and ‘spatial analysis’ remain under-developed, making existing performative design methodologies highly reliant upon the manual execution of analysis and evaluation procedures. This paper presents an evolutionary design process that uses integrative computational pipelines and generatively defined component-based assemblies to produce performative structures in response to solar performance. The resulting structures demonstrate how performative composite behaviour can emerge within ‘disassociated’ componential assemblies and produce complex formal interrelationships which surpass simplistic parametric logics. This offers new possibilities for conceiving highly integrated ‘morphogenetic assemblies’ and suggests trajectories for further research within the field of morphogenetic design.

summary	The issue of collaborative design has been elaborated extensively within the framework of previous CAAD–conferences. Today, an appreciation for traditional attitudes and methods can be observed, but interestingly, a mixture of approaches is also noticeable (computational techniques used in low–tech fabrication environments, for example). This allows for a round–table survey of the current state–of–the–art focused on experiences related to distant learning in the architectural curriculum. To make VDS viable, not only are technological solutions necessary, but so are social (among people) and professional (ways of behavior) ones. In this round–table we aim to identify critical factors of success (or failure).

title	Top-down Approach for Interaction of Knowledge-Based Parametric Objects and Preliminary Massing Studies for Decision Making in Early Design Stages
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 149-164.
summary	Design activities vary from high-degree of freedom in early concept design stages to highly constrained solution spaces in late ones. Such late developments entail large amount of expertise from technical domains. Multiple parallel models handle different aspects of a project, from geometric master models to specific building components. This variety of models must keep consistency with the design intent while they are dealing with specific domains of knowledge such as architectural design, structure, HVAC, MEP, or plumbing systems. Most of the expertise embedded within the above domains can be translated into parametric objects by capturing design and engineering knowledge through parameters, constraints, or conditionals. The aim of this research is capturing such expertise into knowledge-based parametric objects (KPO) for re-usability along the design process. The proposed case study ‚Äì provided by SOM New York‚ is the interaction between a massing study of a high-rise and its building service core, which at the same time handles elevators, restrooms, emergency stairs, and space for technical systems. This project is focused on capturing design expertise, involved in the definition of a building service core, from a high-rise senior designer, and re-using this object for interaction in real-time with a preliminary massing study model of a building, which will drive the adaption process of the service core. This interaction attempts to provide an integrated design environment for feedback from technical domains to early design stages for decision-making, and generate a well-defined first building draft. The challenges addressed to drive the instantiation of the service core according to the shifting characteristics of the high-rise are automatic instantiation and adaptation of objects based on decision rules, and updating in real-time shared parameters and information derived from the high-rise massing study. The interaction between both models facilitates the process from the designer‚Äôs perspective of reusing previous design solutions in new projects. The massing study model is the component that handles information from the perspective of the outer shape design intent. Variations at this massing study model level drive the behavior of the service core model, which must adapt its configuration to the shifting geometry of the building during design exploration in early concept design stages. These variations depend on a list of inputs derived from multiple sources such as variable lot sizes, building type, variable square footage of the building, considerations about modularity, number of stories, floor-to-floor height, total building height, or total building square footage. The shifting combination of this set of parameters determines the final aspect of the building and, consequently, the final configuration of the service core. The service core is the second component involved in the automatic generation of a building draft. In the context of BIM, it is an assembly of objects, which contains other objects representing elevators, restrooms, emergency stairs, and space for several technical systems. This assembly is driven by different layouts depending on the building type, a drop-off sequence, which is the process of continuous reduction of elevators along the building, and how this reduction affects the re-arrangement of the service core layout. Results from this research involves a methodology for capturing design knowledge, a methodology for defining the architecture of smart parametric objects, and a method for real-time-feedback for decision making in early design stages. The project also wants to demonstrate the feasibility of continuous growth on top of existing parametric objects allowing the creation of libraries of smart re-usable objects for automation in design.

summary	Today, with rapidly evolving information technology, computer technologies has become an interface rather than a tool for design process. With the development in computer applications it has become possible to solve design problems which were not possible to handle before. Computer environment which has become an interface rather than a tool for design has also led to the emergence of a number of concepts. New concepts such as Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), Computer Aided Engineering (CAE) are being involved in design process. With the development of Artificial Intelligence (AI) , AI has earned an interdisciplinary position. Agent based systems which are contained in the fields of AI have become the subjects of many researches in design basis. Approach to the problem solving process in the process of architectural/design problems is to be addressed as an important point within the scope of evaluation process. In this context user movements have a very critical role in process of problem solving according to the design problems. While designing or solving a design problem , ignoring the user movements can lead to unwanted results. Within the scope of this study user movements in city are considered in the context of emerging urban part/particles as a preliminary study.

summary	In contrast to such structurally pure models, the power of computation has opened possibilities for at once muddying and synthesizing geometry, structure and material performance. Where the earlier twentieth century experiments employed a more or less uniform tectonic based on symmetrical structural diagrams, contemporary analysis and design techniques can efficiently adapt a material system to address variable, localized, and non-symmetrical loading conditions. This has resulted in projects characterized by non-optimized structural forms that register the impacts of geometry on material behavior with a deviated tectonic system.

title	Designing a Systematic Experiment to Investigate the Effect of Ambient Smell on Human Emotions in the Indoor Space; Introducing a Mixed-Method Approach
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_20

summary	Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

summary	Introduction and Research Questions The research area of urban simulation methods has grown notably in recent decades. Most of the research topics that concern urban simulation have concentrated on defining the complexities of urban environments with certain rules and algorithms. However, cities are getting more complex and changes to them are being made at greater speed. Therefore, current urban simulation modeling approaches based on rules and protocols are still struggling to reduce the gap between the virtual simulation environment and the real cities, since the behavior of citizens is frequently unpredictable and continuously adapting. In this context, research is necessary to develop more fundamental simulation methods that can handle these complexities and changes, leading to new design decision support systems. Therefore, this research was motivated with the following questions: What is the origin of the complexities and transformations of the urban environment? How can we approach the origin to deal with the urban complexities and transformations? To answer these questions, we hypothesize that the diverse human intentions are the origin of the issues that result from all of the complexities and changes of the cities. General Objectives As a result, we propose a participatory simulation environment that brings human intention into the urban simulator: a crowdsourcing [1] simulation platform that is operated by the people‚Äôs participation. To achieve this crowdsourcing urban sustainability simulation environment, we must address the following research issues: categorization of urban sustainability indicators and technologies, inducing mass participations, and an implementation of social network services. Furthermore, we aim at using mobile computing devices, such as smart phones, as a terminal to the simulation environment. Fundamental Goals Our goal is to enable people to share urban information at any time and to compare each other‚Äôs contributions through the crowdsourcing urban simulation platform. The information will be returned to the citizens to support their sustainability-aware life. The simulation platform also gives a chance not only to compare each other‚Äôs levels of sustainability, but also to give self-satisfaction through an altruistic contribution for a sustainable future. Thus, people shall utilize the simulator in order to predict their individual or cities‚Äô future sustainability. Meanwhile, the user data will be collected and delivered to the central server in order to analyze the urban sustainability. Consequently, we can measure the urban sustainability based on a real human interaction, and compare individuals as well as cities. The whole process of this research is presented as a new paradigm of an urban simulator that reflects the urban complexities and the inconstant human mind changes. Specific Objectives of This Paper This paper will represent strategies of the crowdsourcing urban simulation which can make a paradigm shift of urban simulation and shall define the customized sustainable indicators for the initial steps of this research. It shows how as system for can communicate with the public using the current technologies: high performance mobile media, social network services and wide-area geospatial information systems. Furthermore, for the first step of this research, the paper defines the urban sustainability indicators, and their categorization is generalized and translated into simpler ways to support the citizen‚ intuitive understanding.

title	Progress Towards Multi-Criteria Design Optimisation Using Designscript With Smart Form, Robot Structural Analysis and Ecotect Building Performance Analysis"
doi	https://doi.org/10.52842/conf.acadia.2012.047
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 47-56
summary	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

title	Sustainable Conceptual Building Design using a Cognitive System

summary	A cognitive system for conceptual building design is presented. It is based on an adaptive multi-objective evolutionary algorithm. The adaptive approach is novel and, in contrast with conventional multi-objective evolutionary algorithms, it explores the solution space effectively, while maintaining diversity among the solutions. The suitability of the approach for conceptual design of a multi-purpose building complex is demonstrated in an application. In the application, the goal of maximizing sustainability is treated by means of a model, which is established using neural computations. The approach is found to be suitable for treating the soft nature of the sustainability concept. Also, the capability of the approach to compare the performance of alternative solutions from an unbiased viewpoint, i.e. without committing a-priori to a relative importance among the performance aspects, is demonstrated.

source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	TreeHugger - The Eco-Systemic Prototypical Urban Intervention
source	Odysseas Kontovourkis (ed.), Sustainable Computational Workflows [6th eCAADe Regional International Workshop Proceedings / ISBN 9789491207143], Department of Architecture, University of Cyprus, Nicosia, Cyprus, 24-25 May 2018, pp. 75-84
keywords	The paper discusses co-design, development, production, application of TreeHugger (see Figure 1). The co-design among community and trans-disciplinary participants with different expertise required scope of media mix, switching between analogue, digital and back again. This involves different degrees of physical and digital 'GIGA-Mapping' (Sevaldson, 2011, 2015), 'Grasshopper3d' (Davidson, 2017) scripting and mix of digital and analogue fabrication to address the real life world. The critical participation of this 'Time-Based Design' (Sevaldson, 2004, 2005) process is the interaction of the prototype with eco-systemic agency of the adjacent environment - the eco-systemic performance. The TreeHugger is a responsive solid wood insect hotel, generating habitats and edible landscaping (Creasy, 2004) on bio-tope in city centre of Prague. To extend the impact, the code was uploaded for communities to download, local-specifically edit and apply worldwide. Thus, the fusion of discussed processes is multi-scaled and multi-layered, utilised in emerging design field: Systemic Approach to Architectural Performance.

title	Thinking through digital simulation tasks in architectural education
doi	https://doi.org/10.52842/conf.caadria.2011.599
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 599-608
summary	This study reports the activities of 80 second year architecture students at Victoria University, Wellington, New Zealand for the duration of a single trimester. A central theme in this studio is the framing of day-lighting problems into a quantifiable investigation and then addressing these through the use of digital modelling and simulation tools. This study offers an insight to undergraduate architecture students’ negotiation of digital design spaces and asks the question of how the knowledge of skill-based specialist tasks are extensible to core design studio.The mass education within a University environment of such specialist skill based techniques allows for an insight to the negotiation of quantitative and qualitative design criteria. The issue of learning skill based tasks at university level is a pertinent topic of study as the critique of such techniques is implicit to the holistic education of Architects but the level of this critique can vary greatly. This question also highlights the challenges faced to improving the design education approaches to computational thinking and applications.

title	Digital Materiallurgy: On the productive force of deep codes and vital matter
doi	https://doi.org/10.52842/conf.acadia.2011.090

summary	This paper expands the discourse surrounding digital forms of making by scrutinizing the role of materials within computation, ultimately proposing a speculative working model that charts new territory. The growing importance of materials within technological research makes this an appropriate time to consider the nuance of their role within it. Currently, material innovation is happening along two central tracks: the customized cutting, sculpting, and forming of conventional materials with Computer Numerically Controlled (CNC) fabrication equipment and the development of new materials through innovations in material science. Both tracks rely on a limited set of material protocols which enable process-based control and eliminate the intrusion of any unpredictable material variable. Although efficient, such an approach limits architecture’s ability to procure novel material engagements. A few designers are developing an alternative model where computational codes are coupled with eccentric materials to produce unusual results. Digital materiallurgy, as I have called it, is part technique and part attitude; it relies on intentionally ceding limited design control to unpredictable matter—thus capitalizing on matter’s innate ability to produce unexpected formal and material complexity. Digital materiallurgy identifies the intersection of computation and eccentric materiality as a departure point for architectural innovation. By purposefully inserting material heterogeneity and inconsistency into computational means and methods, this work pries apart the apparently seamless relationship between digital design and physical production. By blurring the distinction between physical material and digital form, this work offers an integrated aesthetic experience, one that fetishizes neither the virtual nor the vintage but fuses both into a richer, wilder present.

title	The Pulsating Rhythm of Digital Perception
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 103-106
summary	This paper highlights the role of digital design as catalyst for a new spatial sensibility related to rhythmic perception. It proposes a novel understanding of computational architecture based on the ability of digital design to supersede its commonly accepted instrumental role, demonstrating the potential to engage in deeper issues of the discipline and to invigorate a discourse of part-to-whole relationships through the lens of rhythmic affect. Pulsation introduces the fundamental animate capacity of spatial organizations and critically reshapes our perception of architectural space across multiple scales of a project, from digital inception to fabrication.
