summary	The development of digital technologies in the last twenty years has led to an unprecedented formal freedom in design and in the representation in virtual space. Combining non-standard geometry with CAD tools enables a new way of expression and realization of architectural ideas and conceptions. The transformation of a virtual double-curved surface into a buildable physical structure and object is always accompanied by huge costs and big problems like geometric and statical ones. Our structure is a type of shell structure consisting of plane panels. The load bearing system is organized in a way so that the forces are distributed along the edges of the plane elements. A structure with plane elements supports a high stiffness in combination with a relatively small overall weight. This is due to smooth curved shape of the geometry. We show geometric methods how to control the construction of curved surfaces out of planar building elements. The approach is based on the discretization of the surfaces by plane elements derived from tangent planes. The novel process in this work is that we take the surface curvature at local points into account. This solves former problems which occurred when intersecting the planes. The fact that there is an infinite number of possibilities when selecting tangent planes on a surface raises the issue of the way and conditions which make it possible to select specific tangent planes whose intersection would produce a desired three-dimensional shape. In order to satisfy also aesthetical requirements we engage plane geometrical patterns and ornaments and transfer them into spatial shape. So a three-dimensional ornamental shape is deduced from a two-dimensional ornament. Another task which will be showed is how to limit the infinite range of possibilities to generate a preferred spatial ornament and on what conditions surface tessellation would be ornamental in character, i.e. it would generate not only the functional, but also the aesthetic component of a free-form surface.

summary	Performative Architectural Morphology is a notion derived from the term Functional Morphology in biology and describes the capacity of an architectural material system to adapt morphologically to specific internal constraints and external influences and forces. The paper presents a research project that investigates the possibilities and limitations of informing a robotically manufactured finger-joint system with principles derived from biological plate structures, such as sea urchins and sand dollars. Initially, the material system and robotic manufacturing advances are being introduced. Consequently, a performative catalogue is presented, that analyses both the biological system’s basic principles, the respective translation into a more informed manufacturing logic and the consequent architectural implications. The paper concludes to show how this biologically informed material system serves to more specifically respond to a given building environment.

summary	This paper discusses a collaborative project by RDAI architects, Bollinger+Grohmann and the timber construction company Holzbau Amann. The project is located in a former swimming pool in Paris and it is part of the new interior of a flagship store of the French fashion label Hermes. In late 2009, Rena Duma Architects, asked Bollinger+Grohmann to collaborate as structural engineers on a challenging design proposal within a very short timeframe. Three wooden lattice structures, the so-called “bulle” and one monumental staircase with a similar design approach characterize the interior of the new flagship store. The lattice structures are dividing the basement into different retail spaces. They vary in height (8-9 m) and diameter (8-12 m) and have a free-form shaped wicker basket appearance. Wood was the chosen material for these structures to strengthen the idea of the wickerbaskets and to create an interior space with a sustainable and innovative material.

title	Towards a Morphogenetic Control of Free-Form Surfaces for Designers

summary	The present paper discusses a novel computational design strategy for approximating architectural free form geometry with discrete planar elements by using morphogenetic patterns. We report on an ongoing research project [1], which is focused on the design of flat ornamental tessellations by using computational geometry for the discretization of curved forms rather than manufacturing curvy elements, which typically increase cost. The significance of our approach lies in the fact that it allows the designer to progressively embrace the constructive constraints and their esthetic potential already in the design stage and to follow them through to actual fabrication.

title	Simulation Design Tools: Using Parametric Building Information Modeling and Physical Simulation for Form Finding of Double Curved Surfaces
doi	https://doi.org/10.52842/conf.ecaade.2011.215
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.215-224
summary	Parametric modeling is a powerful tool to create variations of a design following specified criteria. Physical modeling provides flexible relationships between design elements and can simulate the behavior of hanging chain models. Building Information Modeling can contain geometry and design properties and relations. In this paper it is proposed to join all three to create a Simulation Design Tool that allows the intuitive creation of double curved surfaces which follow the rules of funicular systems. This tool is implemented in B-Processor, open-source Building Information Modeling software to bridge the break that occurs when moving from a design software package to Building Information Modeling. It is shown how the tool balances intuitive sculpting and accurate simulation and how the user can interact to mediate different design requirements.

title	ZipShape Mouldless Bending II: A Shift from Geometry to Experience
doi	https://doi.org/10.52842/conf.ecaade.2011.477

summary	“ZipShape is a universal method to fabricate single curved panels from any plain material without moulds” was the first statement of a paper presented at the Antwerp eCAADe conference in September 2008 (Schindler, 2008). In contrast, the paper at hand introduces ZipShape as a highly specific composite combining different materials and their characteristics. Between those two texts, a paradigm shift took place – from abstract geometrical concept to experiencing the inseparable relation of form and material behaviour. This second step of ZipShape-research was initiated by Swiss design office schindlersalmerón through several workshops with Fachschule für Holztechnik Hamburg, CITA at Royal Academy of the Fine Arts Copenhagen, Bern University of Applied Sciences BFH–AHB Biel and The Detmold School of Architecture and Interior Design.

summary	The international architecture of the last decades has examples of works and architectural projects presented graphic from the two-dimensional unfolding of three-dimensional folded surfaces. These valuable individual experiences have not represented generalized strategies that can be transferred to the professional practice and to architectural education. This article uses results of more than 10 workshops (with Unfolding and Folding methodologies) developed in Chile, Argentina and Brazil to build up a pedagogy for the project that makes it possible to investigate the spatial and material properties of folded compositions in Architecture. It proposes to review and update project instruments through the incorporation of Parametric Design; 3D origami software and Digital Manufacturing.

title	Turmitecture: A generic approach for autonomous topological generation
doi	https://doi.org/10.52842/conf.ecaade.2011.558
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.558-562
summary	The paper describes and discusses a generic approach for generative design by Turing Machines operating on a three-dimensionally folded surface. It is part of an on going research on concurrent cooperative design processes in architecture. During the development of systems for simplified generic interaction in spatial design, it turned out that the basic operations are applicable to be processed by non-sophisticated automata. If the spatial configuration is interpreted as the medium for an ordinary state machine, the whole system adds up to a kind of Turing Machine. Since 2D-Turing Machines are often referred to as “turmites”, and the proposed system is based on a yet three-dimensional folded, but still twodimensional surface - the automaton will be called “Turmitect”.

title	Perforating Material Performance: Ceiling Cloud
doi	https://doi.org/10.52842/conf.acadia.2011.x.j6t
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	The focus of this project was to design a ceiling system within a new Materials Resource Center in the Architecture Building that would embody the potential of parametric design and digital fabrication to rethink a generic interior architectural system. The instructors and students in a combined design studio and digital fabrication seminar developed a Ceiling Cloud that clips on to a modified suspended ceiling grid using lightweight folded aluminum panels that are designed to incrementally change dimension and drape into the space below. Constraints and variables within the parametric models allowed for the optimization and extraction of 150 unique panels that are also perforated with their own individual pattern. The variations in the folded surface disburse and dissipate sound through refraction and absorption created by the corrugation in the panels and their perforation. The holes are also calibrated as a gradient to allow more light to penetrate in the center of the space away from the perimeter walls. The project was prototyped by the students as the College of Architecture and partially realized with the help of industrial partners in Houston. The studio was co-directed with Visiting Critic Scott Marble who provided a framework to conduct the studio’s exploration and several successful projects as precedent.

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. 300-307
summary	With digital design and fabrication becoming ever more common in architectural design, the computational geometry topic of discretizing freeform surfaces into flat panels has become a common challenge. At the present, most approaches to the issue of preserving a 2D-tessellation on a freeform surface are focused on optimizing the shape of the structure by approximating geometric “equally-sized” flat patterns. In doing so, these strategies treat the approximation of the desired shape as the primary goal, leaving aside the aesthetical aspect of the paneling, which can be seen as having an ornamental quality. In contrast to these common strategies, the project presented in this paper pursues a more holistic approach that tries to integrate aesthetical as well as structural issues by using more complex as well as more performative patterns for the discretization. In the present paper, we present algorithmic strategies that were designed to integrate from the aesthetics of an exposed timber structure, through analysis of structural loading feedbacks to a detailed level of the physical joint system, as part of the fundamental early design decisions. The consequence of the overall negotiations relies fully on their physical integration through computational design. The present paper discusses both the algorithmic techniques and the joint systems through a series of case studies. At the end of the paper we provide an overview to upcoming tasks including the production of a major structure.

summary	This paper proposes a new interactive design method, called the networked coding method (NC method), which can manage computational design, multi-objective optimization and digital timber fabrication in an interactive design process. First, this paper discusses several drawbacks of the conventional method for architectural design. Second, the paper describes the facilities and equipment of the fabrication laboratory where the NC method was developed. Third, the paper outlines the components of the NC method together with the design process of architectural elements, called integrated fabric 2011. Finally, the paper summarizes several advantages of the method, including the production of an architectural element called the integrated-fabric that integrates various functions into one single element. The method is shown to handle any datasets, including structural and environmental analysis, which were otherwise difficult to integrate into conventional design processes.

title	Automated Cost Analysis of Concept Design BIM Models

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	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	Zero-waste, Flat Pack Truss Work: An Investigation of Responsive Structuralism

summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

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	In the 21st century, as free-form design grows in popularity, grid shells are becoming a universal structural solution, enabling the conflation of structure and skin (façade) into one single element (Kolarevic 2003). This paper presents some of the results of a comprehensive research project focused on the automated design and optimization of grid structures over some predefined free form shape, with the goal of generating a stable and statically efficient structure. It shows that by combining design and FEM software in an iterative, Genetic Algorithms-based optimization process, stress and deformation in grid shell structures can be significantly reduced, material can be saved and stability enhanced.
