title	Balancing Design and Performance in Building Retrofitting: A Case Study Based on Parametric Modeling
doi	https://doi.org/10.52842/conf.acadia.2008.214
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 214-221
summary	Retrofitting the existing building stock will become one of the key fields of action for architects in the future. Due to the raised awareness of CO2 emissions related to the energy consumption of buildings, architects have to increasingly consider parameters influencing the energy performance of their retrofit designs. This is a complex task especially in the early design stages as multiple dependencies between building form, construction and technical systems influence overall energy performance. The inability to cope with this complexity often leads to simple solutions such as the application of massive insulation on the outside, neglecting aesthetic expression and design flexibility. Digital models storing multidisciplinary building information make it possible to include performance parameters throughout the architectural design process. In addition to the geometric parameters constituting the form, semantic and topological parameters define building element properties and their dependencies. This offers an integrated view of the building. We present a case study utilizing mulit-parametric façade elements within a building information model for an integrated design approach. The case study is based on a retrofit project of a multi-family house with very poor energy performance. Within a design workshop a parametric building model was used for the development of the designs. An integrated analysis tool allowed an immediate performance assessment without importing or exporting building data. The students were able to freely define geometric and performance parameters to develop their design solution. Balancing between formal expression and energy performance lead to integrated design sketches, resulting in surprising solutions for the given design task.

title	Chemical Signaling as a Model for Digital Process in Architecture
doi	https://doi.org/10.52842/conf.acadia.2008.340
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 340-345
summary	The role of the architect is quite literally one of assembly: synthesizing the various parts of a project into a cohesive whole. It is a difficult job, often requiring the architect to weave many seemingly contradictory concerns into a solution that benefits them all. It is not surprising then, that the many elegant and effective systems found in nature should be inspiring to the architect. Emerging fields like biomimicry and systems dynamics model the patterns of interaction between organisms and their environments in terms of dynamic part to part and part to whole relationships. ¶ Observations of real relationships between organisms and their environments, as they exist in nature, reveal complex feedback loops working across multiple scales. These feedback loops operate by the simultaneous action of two observed phenomena. The first is the classic phenotypic relationship seen when organisms of the same genetic makeup instantiate differently based upon differences in their environment. This is the relationship that was originally proposed by Charles Darwin in his theory of natural selection of 1859. Darwin’s model is unidirectional: the organism adapts to its environment, but not the other way around. It operates at the local scale as individual parts react to the conditions of the whole. (Canguilhem, 1952). ¶ The second phenomenon, which sees its effect at the global scale, is the individual’s role as consumer and producer in the flows of energy and material that surround it. It is the subtle and incremental influence of the organism upon its environment, the results of which are often invisible until they reach a catastrophic threshold, at which point all organisms in the system feel global changes. ; The research presented in this paper addresses the dialectic between organism and environment as each responds reciprocally to the others’ changing state. Such feedback loops act in a non-linear fashion, across nested scales in biological systems. They can be modeled to act that way in a digital design process as well. This research is an exploration into one such model and its application to architecture: the simple communication between organisms as they affect and are affected by their environments through the use of signal chemicals.

summary	In the current design practice, new digital tools have emerged -visual- also called Infrastructures (Perkel, 2011) such as; Behance 2003, Pinterest 2009, Archdaily 2008, Instagram (2010) -to cite the most recognized in the creative field in Argentina-, which promote different opportunities and support the creative process and problem solving, making it easier for designers to find inspiring material through the Internet. However, very little is known about how these new practices affect professional work, how they themselves see it and the tensions they generate.This article will present the results of a general survey applied to expert designers as part of the first stage of the Doctoral Research project. Which investigates the behavior referred specifically to the use of visual platforms -visual social media- in order to understand, characterize, describe the use and involvement of them within the design process.

title	MODELAGEM GEOMÉTRICA NOS ESTÁGIOS INICIAIS DE APRENDIZAGEM DA PRÁTICA PROJETUAL EM ARQUITETURA. GEOMETRIC MODELING IN THE EARLY STAGES OF LEARNING PRACTICE ARCHITECTURAL DESIGN.

summary	This work invests on delimitation of a Geometric Modeling study program directed to students at the initial stages of Architecture. It is considered that the studies promote a qualified control of the form based on recognition of parameters which define it, moreover it also allows the enlargement of the students geometric vocabulary, important to the architectural design activities. In this way, the program advances on the appropriation of new concepts which surround the investigations on architectural design processes, such as the concept of shape grammar. Observing analysis and architectural composition practices based on such concept, contents of geometric modeling which are already being used in the context of post-graduation are identified to be transposed to the graduation context, along with the initial teaching practices of architectural design. The results refer to making the didactic material available, these materials have the objective of building references for the development of design practice which explore the reflection about the processes of creation and composition of architectural form in their geometric aspects.

title	Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source	International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary	Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

title	Gridshell Tectonics: Material Values Digital Parameters
doi	https://doi.org/10.52842/conf.acadia.2008.118
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 118-125
summary	This paper begins with a simple proposition: rather than mimicking the geometric structures found in nature, perhaps the most effective modes of sustainable fabrication can be found through understanding the nature of materials themselves. Material becomes a design parameter through the constraints of fabrication tools, limitations of material size, and most importantly the productive capacity of material resistance—a given material’s capacity and tendencies to take shape, rather than cutting shape out of material. ¶ Gridshell structures provide an intriguing case study to pursue this proposition. Not only is there clear precedent in the form-finding experiments of Frei Otto and the Institute for Lightweight Structures, but also the very NURBS based tools of current design practices developed from the ability of wood to bend. Taking the bent wood spline quite literally, gridshells provide a means that is at once formally expressive, structurally optimized, materially efficient, and quite simply a delight to experience. The larger motivation of this work anticipates a parametric system linking the intrinsic material values of the gridshell tectonic with extrinsic criteria such as programmatic needs and environmental response. ¶ Through an applied case study of gridshells, the play between form and material is tested out through the author’s own experimentation with gridshells and the pedagogical results of two gridshell studios. The goal of this research is to establish a give-and-take relationship between top-down formal emphasis and a bottom-up material influence.

summary	The proportion of planning activity that concerns existing buildings is increasing steadily throughout Europe. In Germany it is estimated that already two thirds of architectural planning tasks are related to revitalisation, modernisation, conversion and reconstruction. For these types of projects in particular, clients are interested in obtaining an estimate of the building costs as early as possible. Because many details are unknown or can only be guessed, it is often difficult to make a reliable estimate. This article describes a software concept for the rapid, sketch-based capture of data on site with a view to obtaining a cost-assessment for a series of different revitalisation variants using a stochastic approach.

summary	The association of complexity and geometry was the starting point for an academic project at the chair of Computer Aided Design in Detmold. The students were asked to analyze a complex structure - taken from nature, art, technology or society - regarding the underlying geometrical rules and principles. The translation of these abstract geometric principles (logarithmic spiral, polyhedron, rotational solids, mesh-work, double helix…) into a three-dimensional structure was then realized in Rhinoceros. The 3D-modeling was followed by a transformation- and optimization-process of the initial shape by using the evolutionary principles of mutation and selection. The set-up for these variations followed predefined rules and principles for the manipulation of the original structure.

title	Study of Architectural Shape Formation in Comparison with Natural Morphogenesis Using Computer Simulation
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	Geometric accuracy of architectural computer models allows to percept and to analyze the three-dimensional spatial compositions using computer images. The concepts and methodology of modern interdisciplinary science, in particular fractal geometry, have already been successfully applied in the various scientific fields, as astronomy, physics, chemistry, biology. Modern ecological paradigm does not separate human life and anthropogenic world from the natural environment considering all as unitary nonlinear ecosystem. The analysis of the architectural shape formation is a part of the study of morphogenesis in such different worlds, as non-living and living nature and man-made forms – real as well as virtual architecture.

title	Computing Spatial Qualities For Architecture
doi	https://doi.org/10.52842/conf.acadia.2008.472
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 472-477
summary	Computational representation of spatial qualities can lead us to a better understanding of how we construct spatial concepts. Analyses of spatial qualities can support architects in reasoning about the form of a configuration, helping them predict the consequences of a design. ¶ In this paper we present three definitions (enclosure, viewfield, continuity) that describe experiential qualities of architectural spaces. Our project aims to provide computable definitions to these qualities to describe common spatial experiences that are implicitly understood by architects. The description, using familiar terms, reveals the analytical structure of spatial qualities that is based on the geometry of the physical elements. ; We therefore introduce a graphic editor, Descriptor, that provides visualization of spatial qualities as the designer diagrams building elements. The system calculates perceived relationships (surrounded, visible, nearby, nearest) between a viewpoint and the architectural elements based on their geometric properties such as location and distance. The relationships are the components of the three qualities we define. We also present a use scenario to demonstrate how one might use our Descriptor system during early design. ¶ Descriptor is an attempt to formalize descriptions of the spatial qualities to help beginners understand how to make design decisions. In the future, we plan to extend the set of qualities and add detailed attributes of the physical elements to the system.

summary	There is a close relation between building design and fabrication. However still it is mostly a sequential process where the fabrication with its geometric chances and limitations is only to a small extend taken into account in early design phases. In this paper we describe a protoype form work project, realized out of styrofoam cut out with a CNC hot wire-cutting system and coated with the Claraporon coating system. Due to the linear nature of hot wire cutting the surfaces that can be created are ruled surfaces. They are discussed in a more general way as well as first exercises with ruled surfaces in teaching.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

summary	“Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

title	In-Space: Learning to Give Form to Space
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	A perspective represents space as seen from the outside, with the eye of the transcendental subject; an eye –represented by a geometric view point– which not only sees a space, but a space as it is seen by the subject. Motion is inherent to our experience of space which is not fixed and static –like a perspective assumes– but dynamic.

title	Reinterpreting Rasmi Domes with Geometric Constraints:A Case of Goal-seeking in Parametric Systems
source	International Journal of Architectural Computing vol. 6 - no. 4, 375-395
summary	Geometry has long been a generator of architecture. In traditional Persian architecture, Rasmi domes project a drawing onto a predefined 3D geometry. In fact, the word 'rasmi' and the verb for drawing in Persian have the same linguistic root. Projection is readily done in manual drawings or conventional CAD programs. From a constraint perspective, the dome is constrained by the drawing and the 3D geometry. If the latter constraint is replaced by invariance of distance on the original drawing, a class of domes results, but members of this class cannot be computed conventionally. Class members are developable from a planar layout of triangles, which is, in turn, generated by a simple drawing rule. This yields a parametric structure of four parameters. Three determine the initial planar diagram. One determines configuration. Further, domes in the class are mechanisms: they are not fully specified by the constraints and parameters. We develop the geometric constraints representing the location of the defining points of a dome and present a goal-seeking algorithm to solve the constraints within a propagation-based parametric modeling system.

summary	A paradigm shift in the world of architecture brought by the recent developments in visualization and communication technology not only offers us drastically different ways to collaborate, but also questions traditional location dependent collaborations. This new technology offers us new possibilities for a more phenomenologically rich mode of creative activity and participation. The goal of the Participatory Design Studio was to allow architecture students in multiple locations to collaborate in real-time by sharing computational resources, geometric datasets, and multimedia content including high-definition video. The technologies involved in this research include the National LambdaRail (layer 3, PacketNet with 1Gb/s connection) and CA*net 4 (Canadian broadband layer 2 with 10gb/s lightpath connectivity) allowing Standard Definition videoconference, utilization of Deep Computing Visualization, Remote Visual Networking (RVN) and Web Service access and control of the APN devices through the dashboard solution that makes integration seamless to the workflow and transparent to the user.

summary	A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

summary	In this paper, one of traditional Korean residential buildings in the 19th century, Yeongyeongdang, is selected as a model to demonstrate the achievement of the environmental sustainability in the formal composition of traditional Korean architecture. With a computational analysis on the geometric model of Yeongyeongdang using Ecotect, this paper investigates the ecological characteristics employed in the design of the traditional Korean residence and the applications of the sustainable principles for its spatial system.
