summary	The transmission technologies of digital environments propagated by the Internet, specifically the ubiquitous webcam system, present new material to mediate people’s engagement with civic space and simultaneously offer new ways to materialize its three-dimensional form. Recent research shows that the technical functionality of the webcam can be extended through deliberate intervention within the performance of contemporary camera optics. This suggests the development of new techniques for design intervention that operate in direct relationship to the evolution of the very technologies they exploit. With specific focus on the optical and chromatic translational capacities of the camera, the paper will discuss how the manipulation of its colour receptor mechanism not only provides the designer with an opportunity to exceed the constraints of commonly available colour palettes, but also it will show how this digital disruption actively capitalises upon the discrepancies that govern design strategies applied to formal production within coexistent virtual and real-time space. Through the deployment of colour filter array patterns, this new technique is able to extend the working gamut of RGB colour space in a way that that allows chromatic selection for exterior and interior urban space to be linked to programmatic distribution across duplicate environments.

title	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

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
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.799-808
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	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.

summary	The project Knitectonics aims at exploring digital fabrication systems that facilitate optimized, adaptive and specific integrated architectural solutions (Male-Alemany 2010). It is inspired by the beauty of nature systems with their inherent efficiency and performance. The research explored on-site fabrication of monocoques shells, integrating skin and structure along with services and infrastructure, using a simple household technique. It thus embodies a self organized micro system of textures and a macro system of structures. This paper elaborates how the numeric aspects of a textile technique were used, first to digitally imitate the process of assembly and further exploited to develop and visualize a novel fabrication system, based on material research and technical experimentation.

summary	Sustainable design and ecological building are the most significant global challenges for the design profession. To meet new building regulations and national targets for carbon emissions, all future buildings will be judged on their ‘green’ merits. For architects to maintain a competitive edge in a global market, innovation is now key; the design of new processes, technologies and materials that combat carbon emissions and improve the sustainable performance of buildings are paramount. Contemporary practices have responded by setting up multi- disciplinary internal research and development teams, with offices such as Foster + Partners, HOK and Aedas setting the bar for ground-breaking research and development. The aim of internal groups is often to adapt and create new technologies and materials and to borrow ways of working from other disciplines, to focus on innovation rather than incrementally increasing performance or efficiency. This title offers insights into how a wide range of established and emerging practices are rising to meet these challenges. In pursuit of integrated sustainability and low-energy building, material and formal innovation and new tools and technologies, it illustrates that the future of architecture is evolving in an exchange of ideas across disciplines. Incorporating the creation of new knowledge about ecological building within the profession, it also identifies the emergence of a collective will to seek out new routes that build in harmony with the environment.

title	Responsive and Autonomous Material Interfaces
doi	https://doi.org/10.52842/conf.acadia.2011.318
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. 318-325
summary	This paper presents continuing research on responsive systems in architecture; the ability of architectural systems to change certain properties in response to their surrounding environmental pressures. While doing so, it shifts from current and past examples of mechanical approaches of adaptation, towards biological paradigms of seamless material integration. Looking at biological mechanisms of growth and focusing on the material make-up behind them, the research proposes the exploration of material systems in a two-fold interrelated manner: firstly, through passive material systems of variable elasticity, and secondly through the embedment of smart materials with shape-changing properties. The combination of the two is aiming at architectural systems of functional versatility.Through an interdisciplinary approach, the paper examines the following questions: Is it possible to envisage structures that share the principles of adaptation and response of living organisms? What are the technological challenges faced when designing self-actuated responsive interfaces? Which is the conceptual framework for understanding and investigating complex adaptive and responsive systems? By exploring and synthesizing theories and tools from material science, bioengineering and cybernetics the aim is to inform architectural interfaces able to enhance interconnectivity between the man-made and the natural. Focusing on the self-organization of material systems the intention is to suggest architectural interventions, which become sub-systems of their ecological milieu. The emphasis therefore is placed not on architectural formalism, but on how we can define synthetic environments through constant exchanges of energy, matter and information.

title	Architecture = Computer‚ from Computational to Computing Environments
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. 217-232.
summary	Drawing on architecture, urban digital media, engineering, IT and interaction design, the research presented in this paper outlines a possible shift from architecture designed through computation (any type of process, algorithm or measurement done in a computational matter) towards architecture capable of computing (developing, using and improving computer technology, computer hardware and software as a space-defining element). The research is driven by recent developments in four fields, as follows: (a) Architecture in its recent development has shifted from a planar box, as was the ideal in the modernist movement, towards complex and non-standard forms. (b) The design concepts of non-standard surfaces have been adopted into media facades and media architecture by liberating the pixel from its planar position on a screen [1]. (c) Advancements in pervasive computing applications are now able both to receive information from the environment in which they are used and to detect other devices that enter this environment [2]. (d) Developments in advanced autonomous systems such as Human Computer Interaction (HCI) or Human Robot Interaction (HRI), have produced intelligent systems capable of observing human cues and using these cues as the basis for intelligent decision-making [3]. Media fa_ßade developments work in the direction of the above-mentioned four fields, but often come with limitations in architectural integration; they need additional components to interact with their environment and their interactions are both often limited to visual interactions and require the user to act first. The researched system, Polymedia Pixel [4] discussed in this paper, can overcome these limitations and fulfil the need for a space-defining material capable of computing, thus enabling a shift from architecture designed by computation towards architecture capable of active computing. The Polymedia Pixel architecture merges digital technology with ubiquitous computing. This allows the built environment and its relation with digital technology to develop from (a) architecture being represented by computer to (b) computation being used to develop architecture and then further to where (c) architecture and the space-defining objects have computing attributes. Hence the study presented aims to consider and answer this key question: ‚ÄòWhen building components with computing capacity can define space and function as a computer at the same time, what are the constraints for the building components and what are the possible advantages for the built environment?‚Äô The conceptual framework, design and methods used in this research combine three fields: (a) hardware (architecture and design, electronic engineering) (b) software (content design and IT) and (c) interaction design (HCI and HRI). Architecture and urban design determinates the field of application. Media architecture and computer science provide the technological foundation, while the field of interaction design defines the methodology to link space and computing [5]. The conceptual starting point is to rethink the application of computers in architecture and, if architecture is capable of computing, what kind of methodology and structure would find an answer to the above core research question, and what are the implications of the question itself? The case study discusses opportunities for applying the Polymedia Pixel as an architectural component by testing it on: (a) constraint testing ‚Äì applying computational design methodologies to design space (b) singular testing - discussing the advantages for an individual building, and (c) plural testing ‚Äì investigating the potential for an urban context. The research aims to contribute to the field of knowledge through presenting first steps of a System < - > System mode where buildings can possibly watch and monitor each other, additional to the four primary interactive modes of operation. This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

summary	The digital era allows for a new domain of architectural experience. Within a virtual environment designs can be created that go beyond the mere accommodation of literal functions, and that affect and contribute to the human experience by dynamically interacting with and affecting the inhabitants’ life. A key point in “creativity”, considering different disciplines, is the role of previously gained experiences, which cause the emerging of intuition. Accentuating the role of new experiences in enhancing the intuition, by designing in an imaginary world, stands to be an interesting move. Detached from the real one in sense of time and matter, the imaginary world enables the designer to cross the borderline of reality. The hypothesis underlying this ongoing research, from a cognitive point of view, is that the extensiveness of experiences gained by exploring unconventional virtual environments relates positively to both creative performance (enhancing interactivity, lateral thinking, idea generation, etc) and creativity-supporting cognitive processes (retrieval of unconventional knowledge, recruitment of ideas from unconfined virtual environments for creative idea expansion). Practically, the authors propose starting the design from a point cloud in a virtual environment that can be manipulated by the designer immersing in this environment.

doi	https://doi.org/10.52842/conf.acadia.2011.x.v2b
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This paper documents the continuing development and testing of a novel digital work flow established and implemented for the design and redevelopment of formula one racing tracks. The Race Track Modeler (RTM) tool uses a game engine to simulate driving around proposed track designs. Performance data from the simulation is combined with real data acquired from analysis of vehicle mounted accident data recorders (ADRs). The output of the tool is a graphical representation of simulated stopping positions of vehicles that have lost control and left the track. This information directly informs the design of motor racing facilities; the zoning of spectator facilities, position and specification of crash barriers (if required), and surface material selection for the run-off zones (the area where vehicles are expected to stop after losing control and leaving the track). The RTM can suggest further design changes to the track geometry which are then fed back into the game engine. The project involves methods of binding analysis of design directly to geometry together with input from interactive controls. The RTM has been developed and tested during the redevelopment of Silverstone race track in the United Kingdom (figure 1) this paper documents the current state of the tool and concludes with proposed future developments.

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	Visual Dataflow Modelling: A Comparison of Three Systems
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. 801-816.
summary	Visual programming languages enable users to create computer programs by manipulating graphical elements rather than by entering text. The difference between textual languages and visual languages is that most textual languages use a procedural programming model, while most visual languages use a dataflow programming model. When visual programming is applied to design, it results in a new modelling approach that we refer to 'visual dataflow modelling' (VDM). Recently, VDM has becoming increasingly popular within the design community, as it can accelerate the iterative design process, thereby allowing larger numbers of design possibilities to be explored. Furthermore, it is now also becoming an important tool in performance-based design approaches, since it may potentially enable the closing of the loop between design development and design evaluation. A number of CAD systems now provide VDM interfaces, allowing designers to define form generating procedures without having to resort to scripting or programming. However, these environments have certain weaknesses that limit their usability. This paper will analyse these weaknesses by comparing and contrasting three VDM environments: McNeel Grasshopper, Bentley Generative Components, and Sidefx Houdini. The paper will focus on five key areas: * Conditional logic allow rules to be applied to geometric entities that control how they behave. Such rules will typically be defined as if-then-else conditions, where an action will be executed if a particular condition is true. A more advanced version of this is the while loop, where the action within the loop will be repeatedly executed while a certain condition remains true. * Local coordinate systems allow geometric entities to be manipulated relative to some convenient local point of reference. These systems may be either two-dimensional or three-dimensional, using either Cartesian, cylindrical, or spherical systems. Techniques for mapping geometric entities from one coordinate system to another also need to be considered. * Duplication includes three types: simple duplication, endogenous duplication, and exogenous duplication. Simple duplication consists of copying some geometric entity a certain number of times, producing identical copies of the original. Endogenous duplication consist of copying some geometric entity by applying a set of transformations that are defined as part of the duplication process. Lastly, exogenous duplication consists of copying some geometric entity by applying a set of transformations that are defined by some other external geometry. * Part-whole relationships allow geometric entities to be grouped in various ways, based on the fundamental set-theoretic concept that entities can be members of sets, and sets can be members of other sets. Ways of aggregating data into both hierarchical and non-hierarchical structures, and ways of filtering data based on these structures need to be considered. * Spatial queries include relationships between geometric entities such as touching, crossing, overlapping, or containing. More advanced spatial queries include various distance based queries and various sorting queries (e.g. sorting all entities based on position) and filtering queries (e.g. finding all entities with a certain distance from a point). For each of these five areas, a simple benchmarking test case has been developed. For example, for conditional logic, the test case consists of a simple room with a single window with a condition: the window should always be in the longest north-facing wall. If the room is rotated or its dimensions changed, then the window must re-evaluate itself and possibly change position to a different wall. For each benchmarking test-case, visual programs are implemented in each of the three VDM environments. The visual programs are then compared and contrasted, focusing on two areas. First, the type of constructs used in each of these environments are compared and contrasted. Second, the cognitive complexity of the visual programming task in each of these environments are compared and contrasted.

title	Spatial Experience in Real & Virtual Environment as an Urban Design Tool

summary	The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

title	Electropolymeric Technology for Dynamic Building Envelopes

summary	Human health and energy problems associated with the lack of control of natural light in contemporary buildings have necessitated research into dynamic windows for energy efficient buildings. Existing dynamic glazing technologies have made limited progress towards greater energy performance for curtain wall systems because they are still unable to respond to dynamic solar conditions, fluctuating building demands, and a range of user preferences for visual comfort and individual control. Recent breakthroughs in the field of information display provide opportunities to transfer electropolymeric technology to building envelopes that can achieve geometric and spectral selectivity in concert with pattern variation within the façade. Integrating electroactive polymers within the surfaces of an insulated glazing unit (IGU) could dramatically improve the energy performance of windows while enabling user empowerment through the control of the visual quality of this micro-material assembly, in addition to allowing for the switchable patterning of information display. Using parametric modeling as a generative design and analysis tool, this paper examines the technical intricacies linking system variables with visual comfort, daylight quality, and pattern design of the proposed electropolymeric dynamic facade technology.

title	Bodies in Formation: The material evolution of flexible formworks
doi	https://doi.org/10.52842/conf.acadia.2011.098
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. 98-105
summary	Borne from the complex negotiation between liquid mass and tensile constraint, flexible formwork castings are resonant with material energy. Hard as stone, yet visually supple and fluid, the pre-cast architectural assemblies produced using flexible formwork techniques suggest integrative design strategies that acknowledge the intricate associations between form, fabrication, and material behavior. This tripartite synthesis between geometry, making, and performance has emerged as one of the central themes of contemporary architecture and engineering. Borrowing ideas of morphology from biology and physics, 20th century architectural innovators such as Antoni Gaudi and Frei Otto built a legacy of material practice that incorporated methods of making with material and geometric logics. The emergent effects (and affects) produced through these highly integrative practices serve as the basis of much of the research and design at Matsys. Building on the flexible formwork research of Miguel Fisac in the 1970s, the P_Wall series by Matsys explores the use of digital tools in the generation and fabrication of these bodies in formation.

title	Let’s Work Together: A Stigmergic Approach to Acoustic Design
doi	https://doi.org/10.52842/conf.acadia.2011.396
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. 396-403
summary	This paper explores the application of agent-based modeling techniques to the domain of acoustics design. Concepts derived from Stigmergy, which is a class of mechanisms that mediate interactions between social organisms, are applied to a custom implementation of a raytracing based acoustics simulator. Rays are given the agency of changing the geometric and material properties of the surfaces they come in contact with during the raytracing phase. The acoustic simulation process is an active one, where the modeled room environment is adapted while being evaluated. Given performance criteria as input, the simulation process is applied to an auditorium example. The auditorium is adapted and its eventual emergent design has improved acoustic performance. It is hoped that this work will demonstrate the potential of coupling multi-agent systems with simulation processes in order to create new design tools.

title	Parametric materiality: Material properties as catalyst for design

summary	Sustainability issues are increasingly taking more prominent positions in the hierarchy of design decisions. The combination of linked digital analysis and parametric design has emerged as an integrated method of assimilating performative characteristics into design. As these “informed design” methods evolve there is an increasing ability for architectural geometry to be rationalized, whether this is for reasons of constructive optimization, or environmental and economic justification. But the macro scale approach to geometry in design is only one mediator of the designs impact in its surroundings. This paper discusses what happens when designers fundamentally question the role of materials in design, and specifically what happens when “new” materials and their performative characteristics can be modelled and implemented into the digital design decision process. These approaches are showcased in “proof of concept” projects that have been developed using digital design and production technologies, in collaboration with material scientists and industry.
