title	Computational Fluid Dynamics for Urban Design: The Prospects for Greater Integration
source	International Journal of Architectural Computing vol. 9 - no. 1, 33-54
summary	Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment. Its analysis is important to evaluate whether the natural ventilation through a site is adequate to mitigate heat and pollutant to achieve better human comfort in dense urban environments. However, given the complex operational requirements, the response to wind flow is not always done early enough to support planning and design. This paper seeks to illustrate how CFD analysis can aid planning and design of urban areas and investigates the workflow requirements, in the hope of making the CFD simulations more accessible to the practices and contribute to design decisions. It also looks at the present technological advancements and future prospects to assess the scenarios where emerging technologies can make CFD simulation more readily available with affordable and even mobile hardware installations.

summary	This paper questions the context and meaning of space or the ‘spatial’ within the current architectural and urban rhetoric as suggested by Vidler (2011) in his essay Transparency and Utopia: Constructing the void from Pascal to Foucault. As a case in point this paper further introduces the context of ‘non-space’ as supposedly introduced by Le Corbusier in his Potato Building typology studies conducted during the early 1960s. In both the above instances the concept of ‘enlightment space’ or a geometrical, rational gridded and above all transparent space is contrived and skewed to accommodate alternate determinates – space in this instance, according to Vidler; no longer operates as an instrument of monumental construction but rather as an agent of monumental dissolution. Given the above definition, the paper critically evaluates the role of computational design within this spatial decomposition.

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	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

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.

title	A representação das cidades na era da cultura digital: ampliação, consumo e produção das cidades no ciberespaço [The representation of cities in the era of digital culture: expansion, consumption and production of cities in cyberspace ]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 320-323
summary	This article presents a study on the representation of cities in the era of digital culture and aims to show how the phenomenon of self-production is present in the websites studied. At the end, we conclude that cities (through city marketing), local government (through advertising and through the creation of an identity) and citizens (through selfbranding), they create a rhetorical itself and constitute itself as brands. Therefore, we conclude that cybercities has been more an extended space of consumption and production of cities, municipalities and citizens.

title	Biofeedback and Virtual Environments
source	International Journal of Architectural Computing vol. 9 - no. 4, 377-395
summary	This paper explains potential benefits of indirect biofeedback used within interactive virtual environments, and reflects on an earlier study that allowed for the dynamic modification of a virtual environment’s graphic shaders, music and artificial intelligence, based on the biofeedback of the player. The aim was to determine which augmented effects aided or discouraged engagement in the game. Conversely, biofeedback can help calm down rather than stress participants, and attune them to different ways of interacting within a virtual environment. Other advantages of indirect biofeedback might include increased personalization, thematic object creation, atmospheric augmentation, filtering of information, and tracking of participants’ understanding and engagement. Such features may help designers create more intuitive virtual environments with more thematically appropriate interaction while reducing cognitive loading on the participants. Another benefit would be more engaged clients with a better understanding of the richness and complexity of a digital environment.

title	Understanding visual scripts: Improving collaboration through modular programming
source	International Journal of Architectural Computing vol. 9 - no. 4, 361-375
summary	Modularisation is a well-known method of reducing code complexity, yet architects are unlikely to modularise their visual scripts. In this paper the impact that modules used in visual scripts have on the architectural design process is investigated with regard to legibility, collaboration, reuse and design modification.Through a series of thinking-aloud interviews, and through the collaborative design and construction of the parametric Dermoid pavilion, modules are found to impact the culture of collaborative design in architecture through relatively minor alterations to how architects organise visual scripts.

title	A Swell Project: Between Parametrics and Fabrication
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
doi	https://doi.org/10.52842/conf.acadia.2011.x.r0r
summary	As a case study, Swell serves as: 1) an investigation into architectural ornamentation using a contemporary framework, as directed through specific modes of research, 2) a study in fabrication materials and methods, especially through the realization of form, and 3) as a pedagogical tool, loosely assembled through real and virtual space. This essay will focus mainly on the fabrication methods in terms of why and the pedagogical research initiatives and reactions that went into the design of Swell. The project was conceived through a summer studio which was formed to investigate tools and methods available at the Texas A&M Architecture Ranch and to further the local pedagogical direction toward fabrication in architectural design at Texas A&M University as a whole. That is to say, there was no specific agenda toward parametrics, form, research, technology, or the like. At the same time, as the research continued, certain decisions were cast in terms of technology, sensibility, site, etc. informed by research, iterative processes, or parametric evaluation that ultimately formed the project as it exists today.

title	A study of variation of normal of polygons created by point cloud data for architectural renovation field
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. 321-330
doi	https://doi.org/10.52842/conf.caadria.2011.321
summary	Acquiring current 3D space data of cities, buildings, and rooms rapidly and in detail has become indispensable. When the point cloud data of an object or space scanned by a 3D laser scanner is converted into polygons, it is an accumulation of small polygons. When object or space is a closed flat plane, it is necessary to merge small polygons to reduce the volume of data, and to convert them into one polygon. When an object or space is a closed flat plane, each normal vector of small polygons theoretically has the same angle. However, in practise, these angles are not the same. Therefore, the purpose of this study is to clarify the variation of the angle of a small polygon group that should become one polygon based on actual data. As a result of experimentation, no small polygons are converted by the point cloud data scanned with the 3D laser scanner even if the group of small polygons is a closed flat plane lying in the same plane. When the standard deviation of the extracted number of polygons is assumed to be less than 100, the variation of the angle of the normal vector is roughly 7 degrees.

title	BIM’s Seven Deadly Sins
source	International Journal of Architectural Computing vol. 9 - no. 4, 463-480
summary	This paper aims at exposing seven prevailing problems that have emerged in the uptake of Building Information Modelling (BIM) in design practice.The paper provides a reality check between an idealistic view on BIM and the way it is currently applied in daily use. In order to reflect on the issues at hand, the author draws from three years of doctoral research in multidisciplinary design collaboration, followed by more than two years experience as Design Technology director in a large scale architecture practice. In addition to the above, his current role as the chair of the BIM and IPD Steering Group of the Australian Institute of Architects and Consult Australia exposes the author to a broad range of cultural implications of BIM.The findings presented here illustrate that, despite major advances in the development of BIM, there are predominantly cultural roadblocks to its implementation in practice.

title	Aviva Stadium: A case study in integrated parametric design
source	International Journal of Architectural Computing vol. 9 - no. 2, 187-204
summary	The nature of large complex buildings requires specialized skills across a multi-disciplinary team and high levels of collaboration and communication. By taking a parametric approach to design and construction, high quality results can be delivered on budget on time. This type of approach facilitates the opportunity for design teams to work in an iterative manner.A parametric model reduces the time associated with complex design changes while providing a centralized method for coordinating communication. In this paper the recently completed Aviva Stadium is used to illustrate the ways in which these benefits manifest themselves on built work.The authors identify the moments in the design and construction process that truly justify the effort in implementing a parametric approach. By approaching design in this way a “design conversation” can take place between parties involved, resulting in a better building.

title	Decoding Culture Parametrically: Digital Tea House Case Studies
source	International Journal of Architectural Computing vol. 9 - no. 4, 325-338
summary	This paper reviews the Digital Tea House, a workshop held at the University of Tokyo with the aim to build three pavilions for hosting tea ceremony.As first attempts on cultivating formal innovations resulting from digital design process applied to construction of tea houses, the works convey that parametric design can be a mechanism through which architects are able to produce new images of a tea house and renew its conceptual meanings, and that it can be a tool to retain architecture convergent with cultural values.The authors analyze issues addressed in the workshop that range from applications of computational design, interpretations of tradition, structural stability, to solutions for quick physical materialization within limited time and budget.This paper clarifies the following: First, that parametric processes are not contradictory to traditional cultural principles; and second, how traditional elements of the tea house were decoded and formally reinterpreted through parametric designs.

title	Designing Architectural Morphing Skins with Elastic Modular Systems
source	International Journal of Architectural Computing vol. 9 - no. 4, 379-419
summary	This paper discusses the issues of designing architectural skins that can be physically morphed to adapt to changing needs.To achieve this architectural vision, designers have focused on developing mechanical joints, components, and systems for actuation and kinetic transformation. However, the unexplored approach of using lightweight elastic form-changing materials provides an opportunity for designing responsive architectural skins and skeletons with fewer mechanical operations. This research aims to develop elastic modular systems that can be applied as a second skin or brise-soleil to existing buildings.The use of the second skin has the potential to allow existing buildings to perform better in various climatic conditions and to provide a visually compelling skin.This approach is evaluated through three design experiments with prototypes, namely Tent, Curtain and Blind, to serve two fundamental purposes: Comfort and Communication.These experimental prototypes explore the use of digital and physical computation embedded in form-changing materials to design architectural morphing skins that manipulate sunlight and act as responsive shading devices.

summary	This paper focuses on the definition of a conceptual participatory design framework for urban planning. Traditional planning methods can no longer satisfy the growing demands on sustainable urban planning in regard to factors such as complexity, problem size, and level of detail and these limitations make the development of new approaches necessary. Expert knowledge as well as insights from stakeholders and community members needs to take part equally in the decision-making process since they are responsible for a broad understanding and acceptance of final planning decisions. Therefore, a participatory framework is presented in the following, which integrates needs and requirements of stakeholders. In order to enable diverse groups of stakeholders to act conjointly, we propose the application of interactive decision support tools, which will leverage general conclusions especially to solve crucial zplanning decisions.

title	A Long-term Scope of Actions for Reconstructed Cultural Heritage: Maintaining a Virtual Archive of Nonexisting Synagogues
source	International Journal of Architectural Computing vol. 9 - no. 3, 285-302
summary	Reconstruction work on more than twenty synagogues in Vienna has been ongoing for more than a decade. The fact that these sacred buildings no longer exist is a pivotal aspect in this undertaking. Research revealed archived material, however, which served as reliable basis for the reconstruction work. The authors discuss details of the process of handling archival research as well as the decision-making process during reconstruction. The paper focuses on the possibilities and limits of this exploration and discusses the long-term options of handling 3D models, also in the light of continuous changes in the software environments used. The dissemination of results to a large audience and the appropriate illustration of spatial contexts is another aspect that has been explored. The publication of results in the form of a city guide is in line with the objective of conveying the reconstruction results to a large audience.
