title	CAD Scripting and Visual Programming Languages for Implementing Computational Design Concepts: A Comparison from a Pedagogical Point of View
source	International Journal of Architectural Computing vol. 10 - no. 1, 121-138
summary	This paper compares the use of scripting languages and visual programming languages for teaching computational design concepts to novice and advanced architecture students. Both systems are described and discussed in terms of the representation methods they use. With novice students better results were obtained with the visual programming language. However, the generative strategies used were restricted to parametric variation and the use of randomness. Scripting, on the other hand, was used by advanced students to implement rule-based generative systems. It is possible to conclude that visual languages can be very useful for making architecture students understand general programming concepts, but scripting languages are fundamental for implementing generative design systems. The paper also discusses the importance of the ability to shift between different representation methods, from more concrete to more abstract, as part of the architectural education.

title	Architecture of an Active Context
doi	https://doi.org/10.52842/conf.acadia.2012.269
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. 269-276
summary	As we stand with our feet on earth’s outermost surface we build an architecture today that is much like it was several thousand years earlier, in an attempt to extend that outer shell with one of our own making. Artificial masses are built from a refinement of this existing geologic layer into materials of stone, steel, concrete, and glass that assemble to produce new pockets of space through the buildings they create. However, the sixth century BC writer Thales of Miletus put a different perspective on this: he insisted that we live, in reality, not on the summit of a solid earth but at the bottom of an ocean of air (Holmyard 1931). And so, as architecture continues to build up the outermost layer of earth’s surface through a mimicking, embellishing, and enhancing of the materials which it comes from, it raises the question of why we have not brought a similar relationship to the materialities at the bottom of this “ocean” of air to create the spaces we call architecture. If you were looking to level a complaint with the architectural profession, stating that it has not been ambitious enough in scope would not be one. Architects have never shied away from the opportunity to design everything from the building’s shell to the teaspoon used to stir your sugar in its matching cup. But it would seem that the profession has developed a rather large blind spot in terms of what it sees as a malleable material with which to engage. Architects have made assumptions as to what is beyond our scope of action, refraining from engaging a range of material variables due to a belief that the task would be too great or simply beyond our physical control. So even though we are enveloped by them continuously, both on the exterior as well as the interior of our buildings, it must be assumed that the particles, waves, and frequencies of energy that move around us are thought by architects to be too faint and shaky to unload upon them any heavy obligations, that they are too unwieldy for us to control to create the physical boundaries of separation, security, and movement required of architecture. This has resulted in a cultivated set of blinders that essentially defines architecture as a set of mediation devices (surfaces, walls, and inert masses) for tempering the environmental context it is situated in from the individuals and activities within. The spaces we inhabit are defined by their ability to decide what gets in and what stays out (sunlight, precipitation, winds). We place our organizational demands and aesthetic opinions on the surfaces that mediate these variables rather than seeing them as available for manipulation as a building material on their own. The intention here is to recalibrate the materialities that make up that environmental context to build architecture. The starting point is a rather naive question: can we design the energy systems that course in and around us daily as an architectural material so as to take on the needs of activities, securities, and lifestyles associated with architecture? Can the variables that we would normally mediate against instead be heightened and amplified so as to become the architecture itself? That which many would incorrectly dismiss as simply “air” today—thought to be homogeneous, scale-less, and vacant due in part to the limits of our human sensory system to perceive more fully otherwise—might tomorrow be further articulated, populated, and layered so as to become a materiality that will build spatial boundaries, define activities of individuals and movement, and act as architectural space. Our environmental context consists of a diverse range of materials (particles and waves of energy, spectrum of light, sound waves, and chemical particles) that can be manipulated and formed to meet our needs. The opportunity before us today is to embrace the needs of organizational structures and aesthetics by designing the active context that surrounds us through the material energies that define it.

title	Robotic Construction by Contour Crafting: The Case of Lunar Construction
source	International Journal of Architectural Computing vol. 10 - no. 3, 423-438
summary	Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

title	Digital Architecture at Crossroads – Transition from Simulation and Visualisation to Information Modelling
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 5
summary	Digital architecture is at an exciting but challenging stage of its development. Past decades have witnessed important developments in computer-generated architectural representations. These tools have complemented and, in some cases, superseded the traditional forms of design and communication. In parallel with progress in computer graphics, advances in computer generated architectural representations have evolved to deliver photorealistic computer generated imagery. However, there is evidence to suggest that these advances have not significantly enhanced collaborative practices. It was acknowledged that to address the fragmentation of the industry, a fundamental change to deliver digital architecture was needed. Dealing with the requirements for an improved co-ordination and co-operation between designers and other stakeholders to encourage more integration has therefore become a central issue in the last decade. It was also recognised that significantly more intelligence needs to be brought to bear on the decision-making process if the targets set by the sustainability agenda are to be met. The quest for an improved quality of information and decision making has shifted the emphasis from computer-generated imagery to integrated building information. The recent emergence of building information modelling (BIM) constitutes one of the most exciting developments in the field. It was suggested that BIM will deliver considerable sophistication and judgment in decision-making. This keynote speech seeks to examine the implications of the transition of digital architecture from simulation and visualisation to information modelling. It aims to shed light on the methodological and technological challenges facing practitioners, researchers, and software developers, as a result of the early adoption of BIM.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 268-271
summary	The information produced for the design and construction of buildings become increasingly complex and are inseparable parts of the whole social making of the City. It have created a transition that should consider the integrative and collaborative aspects the architectural design process. This new transition demand changes in the architectural education in response to the resulting complexity in the design concept, given that the potential of the innovation in digital technologies is not about the generation of forms but the change that occur in the organization of activities.

title	A Method for the Realization of Complex Concrete Gridshell Structures in Pre-Cast Concrete
doi	https://doi.org/10.52842/conf.acadia.2012.209
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. 209-216
summary	This paper describes a method for the design and fabrication of complex funicular structures fromdiscrete precast concrete elements. The research proposes that through the integration of digitalform-finding techniques, computational file-to-fabrication workflows, and innovative sustainableconcrete casting techniques, complex funicular structures can be constructed using prefabricatedelements in a practical, affordable, and materially efficient manner.A recent case study is examined, in which the methodology has been used to construct a pavilion.Custom-written dynamic relaxation software was used to define the overall form and successivealgorithms; it then defined each component’s unique geometry, unrolled into flat shapes, andnested all parts into cut-files. PETG plastic sheets were two-dimensionally laser cut and folded toproduce the unique casting molds. The case study was carried out in collaboration between theAarhus School of Architecture and the University of Technology, Sydney (UTS). Basic research incasting techniques defined the framework for the design process, and a custom-written dynamicrelaxation software application became the primary form-generating tool in the design process ofa constructed pavilion. Fabrication and construction constraints were embedded within the designof both the overall structure and its components. Finite element analysis [FEA] was completed inorder to verify the form-finding results, to ensure structural stability, and to direct adjustments ofthe structure during the design process.The constructed pavilion case study, constructed in a very short time, for low cost and with relativelyunskilled labor, demonstrates that the integration of algorithmic form-finding techniques, CNCfabrication workflows, and the use of innovative PETG folded-mold techniques enables thepractical realization of freeform funicular structures in precast concrete.

title	INTELLIGENT KNOWLEDGE-BASED REPOSITORY TO SUPPORT INFORMED DESIGN DECISION MAKING
source	ITCON journal
summary	Research highlights that architectural design is a social phenomenon that is underpinned by critical analysis of design precedents and the social interaction between designers including negotiation, collaboration and communication. CAAD systems are continuously developing as essential design tools in formulating and developing ideas. Researchers such as (Rosenman, Gero and Oxman 1992) have suggested suggest that knowledge based systems can be integrated with CAAD systems to provide design knowledge that would enable recalling design precedents that maybe linked to the design constraints. Currently CAAD systems are user centric being focused on architects rather than the end product. The systems provide limited assistance in the production of innovative design. Furthermore, the attention of the designers of knowledge based systems is providing a repository rather than a system that is capable to initiate innovation. Most of the CAAD systems have web communication tools that enable designers to communicate their design ideas with colleagues and partners in business. However, none of these systems have the capability to capture useful knowledge from the design negotiations. Students of the third to fifth year at College of Architecture, University of Dammam were surveyed and interviewed to find out how far design tools, communications and resources would impact the production of innovative design projects. The survey results show that knowledge extracted from design negotiations would impact the innovative design outcome. It highlights also that present design precedents are not very helpful and design negotiations between students, tutors and other students are not documented thus fully incorporated into the design scheme. The paper argues that the future CAAD systems should be capable to recognize innovative design precedents, and incorporate knowledge that is resulted from design negotiations. This would help students to gain a critical mass of knowledge that would underpin informed design decisions.

title	Hybridizing Digital Fabrication Techniques
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 103-114
summary	The use of digital fabrication in the production and making of architecture is becoming a prevalent vehicle for the design process. As a result, there is a growing demand for computer-aided design (CAD) skills, computer-aided manufacturing (CAM) logic, parametric modeling and digital fabrication in student education. This paper will highlight three student projects that look to ingrate computational prototyping with digital fabrication techniques in the production of architecture. The goal is to hybridize fabrication techniques of sectioning, tessellating and folding to educate students in CAD, CAM, parametric modeling and digital fabrication. Rather than repeating conventional approaches or recreating from precedent, mixing techniques challenges students to understand the CAD technique or parameters for modeling, translate for CAM production and deal with real world constraints of materials, time and tectonics. In the end, these projects are critical of the digital and projectively speculate on the architectural detail in an age of digital ubiquity.

title	Parametric building typologies for San Francisco Bay Area: A conceptual framework for the implementation of design code building typologies towards a parametric procedural city model
doi	https://doi.org/10.52842/conf.ecaade.2012.1.187

summary	This research paper concentrates on a conceptual framework for the creation of high-level procedural city models. A workflow is presented, which enables users to create city models in an intuitive way by using design-code-driven building typologies. This drastically advances traditional procedural city modelling where usually low-level implementations of city model components take place. New planning methods and instruments have to be developed for the growing demand of the rapid environmental, social and economic changes in cities and agglomerations. The presented method allows for quick visualization and iteration by using urban planning typologies.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 458-461
summary	This paper presents the results of an exploratory study developed with the Autodesk Project Vasari and AutoCAD Civil 3D. Project Vasari was used to evaluate the environmental performance of a low-income housing project. It shows us that the actual site orientation of the project presents poor environmental performance, which could be improved by rotating building in 90 degrees. The AutoCAD Civil 3D was used to evaluate how that rotation should impact on earthmoving. The results showed that the simulations developed, even though having low level of accuracy, provide sufficiently clear information to support decision making on conceptual mass project stage.

title	Composite Territories: Engaging a Bespoke Material Practice in Digitally Designed Materials
doi	https://doi.org/10.52842/conf.ecaade.2012.2.691
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 691-699
summary	Today, material performance is regarded as one of the richest sources of innovation. Accordingly, architecture is shifting to practices by which the computational generation of form is directly driven by material characteristics. At the same time, there is a growing technological means for the varied composition of material, an extension of the digital chain that foregrounds a new need to engage materials at multiple scales within the design process. Recognising that the process of making materials affords perspectives not available with found materials, this paper reports the design and assembly of the fi bre reinforced composite structure Composite Territories, in which the property of bending is activated and varied so as to match solely through material means a desired form. This case study demonstrates how one might extend the geometric model so that it is able to engage and reconcile physical parameters that occur at different scales.

title	Information Technology Utilization in Architectural Engineering: A Field Investigation at the Department of Architecture and Construction, Constantine (Algeria)
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 155-156; 273-284
summary	This paper is derived from an under developed research work, that is a PhD thesis which studies the influence of Information Technology (IT) on architectural practice in Algeria. It examines the use of IT by students of the Department of Architecture and Construction in Constantine in their design studio’s projects. The target of the study is to inspect the depth of utilization of IT, identify the advantages and shortcomings of use, and propose some solutions. A field survey was undertaken on a sample of students at the Department of Architecture and Construction. The survey has the following objectives: • to find out the students’ motivation behind the adoption and use of IT in their projects; • to identify the negative and positive aspects of use; • to identify the barriers that would hinder better use; and • to determine the impact of the IT tools on the design process and projects. // For a more comprehensive comprehension of the study case; a pilot field survey was conducted during two consecutive years. This enables the researchers to make comparisons between the survey’s results of the same year, and to study the trends of use by making comparisons between the results of these two years. SPSS was used to analyze the results. The analysis of results shows that the IT helps largely to improve the quality of presentations of the documents, images and graphics but this was an attempt from students to satisfy and influence the "others". In some cases, this has negatively affected the quality of design projects. It was used by students with poor design skills to cover up some weak aspects and faults in their design projects. On the other hand, some tutors opposed the exaggerated use of IT and the complete dependence on the computer during the design stage. They prefer the "traditional way" of design development. There is an ongoing conflict and arguments between students and tutors regarding this matter. However, It was noticed that the IT has effectively contribute in improving the competition level between students thus the quality of their design projects.

title	Crowdsourcing Architecture: A Disruptive Model in Architectural Practice
doi	https://doi.org/10.52842/conf.acadia.2012.439

summary	This paper discusses the use of crowdsourcing as a new approach for architectural design acquisition. We will give an overview of the concept of crowdsourcing, and elaborate on its particular application in architecture via concrete projects executed on Arcbazar, a firstof- its-kind crowdsourcing platform for architectural design services. We argue that online crowdsourcing platforms can have an immense impact on smaller-scale design challenges, e.g., home remodeling projects and landscape and interior design challenges, and can potentially carry these often neglected projects into the architectural design sphere. In this paper we will discuss the methods and techniques of architectural crowdsourcing and illustrate the processes and outcomes through a series of projects: a remodeling project for a closet; an interior design challenge for a dining space; and a layout problem for an apartment complex. We will then evaluate the protocol and outcome of architectural crowdsourcing, and convey the professional and popular media response to this new method of architectural design acquisition.

title	An Integral Approach to Structural Optimization and Fabrication

summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

summary	Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC) (Mcgee 2011). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure (Sondergaard & Dombernowsky 2011). A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase (Xie 2010), the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive.

summary	From the beginning of digital revolution, structural surfaces drew significant attention as a realm that interweaves formal explorations, form-finding and structural optimization. However, after successful experimentation in the virtual domain, it became evident that some of the main challenges lay on how to translate these structural forms into architectural assemblies at the scale of buildings. The development of digital fabrication is crucial in this task, as means to overcome traditional constraints such as need for modular pieces, scaffolding and optimal assembly sequences.This research focuses on digital workflows that combine form finding with robotic fabrication, surface tessellation and panelization. In the past years, the use of digital tools to assemble identical modules into complex formations has achieved significant results for loadbearing walls. Expanding this line of research, the proposed fabrication system carries these experiments on additive fabrication into the production of structural surfaces. The assembly sequence involves a two-step fabrication: off-site panel manufacturing and on-site assembly. The main components of the system consist of two triangular ceramic pieces that provide structural resistance, refined surface finish, and formwork for thin reinforced-concrete layer. Panelization strategies reduce the requirements on-site work and formwork.The paper describes background research, concept, construction process, methodology, results and conclusions.

summary	This paper explores how an algorithm designed to represent form can be made physical, and how this physical instantiation can be made to respond to a set of design imperatives. Specifically, the paper demonstrates how Marching Cubes (Lorensen and Cline 1987), an algorithm that extracts a polygonal mesh from a scalar field, can be used to initiate the design for a system of modular concrete armature elements that permit a large degree of variability using a small number of discrete parts. The design of these elements was developed in response to a close examination of Frank Lloyd Wright's Usonian Automatic system, an architecturally pertinent historical precedent. The fabricated results positively satisfy contemporary design criteria, including maximal formal freedom, optimal environmental performance, and minimal life-cycle costs.

summary	In this work we address the fast and economical realization of complex formwork for concrete with the advantage of industrial robot arm. Under economical realization we mean reduction of production time and material effi ciency. The complex form of individual formwork parts can be in our case double curved surface of complex mesh geometry. We propose the fabrication of the formwork by straight or shaped hot wire. We illustrate on several projects different approaches to mould production, where the proposed process demonstrates itself effective. In our approach we deal with the special kinds of modularity and specific symmetry of the formwork.
