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	Through the automation of folding of sheet metal components by a six-axis industrial robot we explored the integration of parametrically-driven design and fabrication tools and its real-world implementation. Developed out of research into new possibilities presented by direct programming of flexible, digitally-driven, industrial tools, this project intends to speculate about the future implementation of parametric modeling tools in the field of design, and associated new, parametrically variable, fabrication processes. We explored the relationship between designer and machine, between data and craft, and tested conjectures about scale of production, through the digital creation, physical cutting, mental tracking, robotic folding, manual riveting, and sometimes painful installation of five hundred and thirty two unique sheet metal components. Such evaluations give insight into possible trajectories for development of new models of fabrication processes, questioning the scale and intellectual scope appropriate for custom fabrication environments, and the implicit need to then evaluate the incorporation of digital craft in design pedagogy.

title	Formation Embedded Design: A methodology for the integration of fabrication constraints into architectural design
doi	https://doi.org/10.52842/conf.acadia.2011.122
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. 122-131
summary	This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

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.

summary	This paper reflects about the potential of integrating meaning into parametrics that can be produced by the linkage between information visualization interfaces and custom parametric modeling systems. The inclusion of unstable semantics from web-based geo-referenced information is proposed, as driver for producing extreme differentiation and systemic complexity in contemporary design practices.

title	Parametric urban design: An interactive sketching system for shaping neighborhoods

summary	In this paper we show the structure of an urban design parametric system. The system is dynamic and builds an interactive relation with the designer updating the layout and related data at each input change. The responsiveness of the system allows the designer to gain awareness on the qualitative consequences of each design move by comparing a design state with a set of urban indicators and density measures which are automatically calculated along with the geometrical updates.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
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	Using domain specific languages in the Building Information Modelling workflow
doi	https://doi.org/10.52842/conf.caadria.2011.731
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. 731-740
summary	The design of architecture, in practice, entails the collaboration of many disciplines each with their own set of tools and representations. Building Information Models aim to support interoperability between these disciplines. However current implementations require a lot of manual work involving translating parts from the various specialised descriptions to the common model format. Domain Specific Languages are a development from Information Technology that defines a mapping from the concepts used in one discipline to those used in another. In this paper, a workflow incorporating the movement between specialised languages and a central model is described. The central model is structured using the Industrial Foundation Classes (IFC). The motivation for elaborating on the interdisciplinary workflow is the desire to create a more iterative process without the need for the manual recreation of models. While it is difficult to have a description or language that contains all the information of all the disciplines, this research demonstrates how the IFC schema acts as a pivot not just between data sets, but also between concepts expressed in different representations thus giving from analysis to design.

title	Digital Form Finding: Generative use of simulation processes by architects in the early stages of the design process
doi	https://doi.org/10.52842/conf.ecaade.2011.107

summary	The paper presents performance oriented approaches to digital form finding which stems from the lines of research on performance and morphogenesis in architectural design. The main contribution to the earlier research is threefold; it examines the potential of the presented design processes to integrate interdisciplinary approach based on the use of simulation tools by architects or direct data exchange between simulation tools and design. Secondly, it explores new methods to generate initial architectural form based on performance information that apply to both building scale and urban scale, and lastly, it develops the theoretical framework on the ramifications of employing simulation technology and techniques in architectural design.

title	Gains, losses and limitations in designing parametrically: A critical reflection of an architectural design studio in China
doi	https://doi.org/10.52842/conf.caadria.2011.569
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. 569-578
summary	This paper argues that learning to design parametrically in the architectural studio entails gains but also losses, since the parametric design approach tends to and encourage certain patterns of thought while discouraging others. This investigation complements previous research focusing mostly on technological aspects. Based on observational data from a parametric design studio in China, this paper discusses how parametric designing can pose challenges to existing design values and approaches, specifically within a Chinese context. It further draws attention to the limitations of parametric designing, which in the observed cases required both students and teachers to break and extend parametric models besides and beyond parametric variation to make them work architecturally. This paper aims to inform educators employing parametric designing in their architectural design studios as well as researchers who examine such studios.

summary	Architects have developed and employed parametric design strategies to both address these performance related concerns and improve their production. Though these strategies have improved architectural design, they are not being used to their full extent in the design process. I propose taking the use of computers in aiding architectural design one step further; information and data should INFORM the project, driving the creation of a building FORM enabling it to PERFORM at higher levels than traditional design.

title	Race track modeler. Developing an Iterative Design Workflow Combining a Game Engine and Parametric Design
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.

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	Sensitive skin design: a generative approach

summary	This paper presents a framework of study of an iterative evolution of a modular component designed in an attempt to simulate material constraints and motional response with the perspective to be multiplied into a dynamic system. The main scope of this project was to investigate the process that maps a territory of possibilities, among which lies the potential architectural solution. In order to explore this field a parametric model has been developed. The simulation of the materials nature has been embedded in the algorithm on a geometry constraint basis in an attempt to simulate the behavior of the system comprised by elements in tension and torsion. A multiplication process of the module was introduced at a following stage of the research focusing on regular tessellations and circle packing on the plane. Responsive performance has been studied on a selected specimen of the evolution given a hypothetic context scenario according to which the scale of the design was set at a façade component level. The resulting responsive permeable skin was presented as a potential design solution among the successive approximations of this algorithm. Along the course of the research the parametric tools were used not only as a medium of synchronous output visualization but also as a mechanism to simulate material properties, structural constrains, environmental data, and worked as stimuli of inspiration driving the overall design process.

summary	The goal of this paper is to present the feasibility computing tool for the perimeter block housing design in early design process. Firstly, the paper describes briefly issues of perimeter block housing focusing on block design cases of Seoul. Secondly, constraints and requirements of perimeter block housing are analysed and formulated based on specific zone ordinance and regulation.

summary	This paper proposes the use of a new set of software tools, called Firefly, paired with a low-cost five-axis robotic motion controller. This serves as a new means for customized tool path creation, realtime evaluation of parametric designs using forward kinematic robotic simulations, and direct output of the programming language (RAPID code) used to control ABB industrial robots. Firefly bridges the gap between Grasshopper, a visual programming editor that runs within the Rhinoceros 3D CAD application, and physical programmable microcontrollers like the Arduino; enabling realtime data flow between the digital and physical worlds. The custom-made robotic motion controller is a portable digitizing arm designed to have the same joint and axis configuration as the ABB-IRB 140 industrial robot, enabling direct conversion of the digitized information into robotic movements. Using this tangible controller and the underlying parametric interface, this paper presents an improved workflow which directly addresses the shortfalls of multifunctional robots and enables wider adoption of the tools by architects and designers.

summary	The creation of building components that can be seen as sustainable, inexpensive, stronger, recyclable, customizable and perhaps even reparable to the environment is an urgent, and critical focus of architectural research. In the U.S. alone, the construction industry produced 143.5 million tons of building-related construction and demolition debris in 2008, and buildings, in their consumption of energy produce more greenhouse gasses than automobiles or industry.Because the inherent nature of 3D printing opens new possibilities for shaping materials, the process will reshape the way we think about architectural building components. Digital materiality, a term coined by Italian and Swiss architects Fabio Gramazio and Matthias Kohler, describes materiality increasingly enriched with digital characteristics where data, material, programming and construction are interwoven (Gramazio and Kohler, 2008). The research aspires towards this classification through the use of parametric modeling tools, analytic software and quantitative and qualitative analysis. Rapid prototyping, which is the automatic construction of physical objects using additive manufacturing technology, typically employs materials intended for the immediate analysis of form, scale, and tactility. Rarely do the materials used in this process have any long-term value, nor does the process - except in rare cases with expensive metal prototyping - have the ability to create actual and sustainable working products. This research intends to alter this state of affairs by developing methods for 3D printing using concrete for the production of long-lasting performance-based components.

title	Informing Architecture and Urban Modeling with Real-world Data on 3D Tangible Interfaces and Augmented Displays
doi	https://doi.org/10.52842/conf.acadia.2011.226

summary	The proliferation of online and digital data in our world yields unprecedented opportunities for connecting physical and digital parametric models with live data input and feedback. Tangible interfaces and augmented displays provide theatrical settings for designers to visualize real-world data and experience realtime feedback while manipulating physical and digital models on the table. This paper proposes a new approach to design workflow, where physical model and virtual model can be interconnected and informed in realtime by multiple analytical datasets and live data streams. Using 3D scanning, blob detection, and multi-touch techniques, multidimensional tangible interfaces and augmented displays presented in this paper demonstrate a powerful new approach for designing and interacting with physical models, materials, and environmental data.

title	Integrated Design Process for Prefabricated Façade Modules with Embedded Distributed Service 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. 419-434.
summary	The awareness of the environmental impact of buildings concerning their CO2 emissions, their energy and resource consumption has raised the challenges on building design, construction and operation. Building service systems are among the main contributors to building related emissions. Their consideration already in design is therefore of growing importance. Distributed service systems represent a new paradigm towards the supply of a building with energy and matter. Being small, efficient and networked, they can be distributed within the building fabric to allow an efficiently supply of the building space. Their employment, however, affects the spatial layout, construction and resulting building performance. In order to capture the resulting complex dependencies, a strategy to integrate such systems into the architectural design process is necessary. In this work a design process is proposed, that integrates distributed service systems into building design, dissolving the classical divide between architectural design and service systems layout. Digital modelling and computational methods are employed to create and analyse design solutions, visualize performance criteria and provide the relevant data for the intended digital fabrication process. The process is exemplified using a joint university-industry case study project focusing on parametric façade modules, developed in a seamless digital process from concept to fabrication.
