summary	Recent game technology ascends development of low-cost virtual environment to the next level in two domains : reality representation and user interaction or engagement. In architecture and urban design realm, realistic 3D representation become more important in such way of conceptualizing ideas and analyzing the context of design problem. This research will present development of virtual urban environment using game engine technology. Aim of this research is to promote game engine as a tool for visual representation, visual analysis and further basic tool for urban design study. At the end, we point out potentials as well as constraints both in technical and design method issues in game technology based on the research findings.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title	Technologies for interactive displays [Tecnologias de displays interativos no processo de projeto arquitetônico]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper aims to discuss the possibilities of interactive displays in architecture´s design, the article starts discussing how the computational methods transformed the way of thinking architecture. Then are presented and analyzed some technologies that can be built into the workshop of the project architecture, among them: opaque and LCD tablets, chambers of immersion, whiteboards and interactive screens and equipment´s of tangible digital information (Tangible Bits). It appears that the trend of technological innovations is a mix of traditional and digital, facilitating the manipulation and production of drawings by architects through direct touch, some of the technologies are already considered viable, providing low cost and good results during the practice of design.

title	The Intelligence of ornaments: Exploring ornamental ways of Affordable Non-Standard Building Envelopes
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 417-425
doi	https://doi.org/10.52842/conf.caadria.2008.417
summary	The purpose of this research is to explore ornamental patterns which can be used to enhance materials characteristics in low-cost building envelopes. We use standard building materials (sheets of cross-laminated timber) and develop a parametric design framework for the assembly. Existing rules of ornamental geometry are applied to a parametric controlled structural model so as to endow the building parts both with stability and aesthetics. The concepts of mass customization and “File to factory” support the digital fabrication of a non-repetitive pattern in façade construction and lead to reduced construction costs and building time.

summary	In our research work we proposed a method to construct an image data base from which designers can find solutions for their design problem. In our approach, an image is not only a media representing existing objects or existing scenes, but it is a support which allow the designer to advance in solving his problem. In this paper we tackle the particular question of the analyses of the results obtained thanks to an experiment which aims to validate a method to index and retrieve images. The objective of this experiment is to evaluate the real contribution of the images retrieved by our system to the designer when he looks for solutions to a design problem. By the analyse of the indexation terms we aim to evaluate the real help that this reference image database can bring to the designer during his creation work.

title	ARCHITECTURE ‘in computro’ - Integrating methods and techniques
source	26th eCAADe Conference Proceedings [ISBN 978-0-9541183-7-2], Antwerp (Belgium) 26-29 September 2008, 968 p.

summary	The presence of both visible and hidden digital resources in daily life is overwhelming and their presence continues to grow exponentially. It is surprising how little the impact of this evolution is questioned, especially in education. Reflecting on past experiences of this subject to learn for the future seems rarely to be done, and the sheer fact that a digital method exists is often seen as sufficient justification for its use. Are these the perceptions of serious misgivings or isolated views that circulate in the educational world and beyond? We would suggest that the eCAADe (Education and Research in Computer Aided Architectural Design in Europe) and its conferences provide the ideal forum to provide answers in this debate. For the first conference in what is to be the next quarter century of the existence of eCAADe, a theme was chosen that could easily include all aspects of this debate: ARCHITECTURE ‘in computro’ , Integrating methods and techniques It seems a bit vulgar to use a dog-Latin phrase ‘in computro’ for such a serious matter but at least it now has a place between ‘in vivo’ and ‘in vitro’. For more than 25 years CAAD has been available, and has been more and more successfully used in research and commercial architectural practice. In education, which by definition should prepare students for the future, the constantly evolving CAAD metaphor is provoking a challenge to cope with the ever expanding scope of related topics. It is not surprising that this has led to differing opinions as to how CAAD should be taught. Questions such as how advanced research results can be incorporated in teaching, or if the Internet is provoking self-education by students, are in striking contrast with the more fundamental issues such as the discussion on analogue versus digital design methods. Is CAAD a part of design teaching or is it its logical successor in a global E-topia? Although the E of education is a prominent factor in the ‘raison d’être’ of the organisation, the papers presented at this conference illustrate that eCAADe is open to all other relevant contributions in the area of computer-aided architectural design. It will be a fortunate coincidence that this exchange of knowledge and opinions on such state-of-the-art subjects, will be hosted by the The Higher Institute of Architectural Sciences, Henry van de Velde, located in the historical buildings of the Royal Academy of Fine Art established since the founding of the academy in 1662.

summary	This paper presents a simple web-based GIS system for visualization of Baan Mankong, as known as sustainable housing projects for communities of low-incomers in Thailand. The Baan Mankong project has been so successful that numbers of projects initialized have been increasing during the past couple of years. The projects information is gathered in a huge database, but there is a lack of visualization tool to help the officers and executives to have a global view of the projects’ spatial distribution and to have a quick access to project information. GIS is proposed as a tool to be developed on the web for the visualization of this project. The Baan Mankong’s work flow and project information are studied in order to select only necessary information to be stored in the system. Then, the geographic visualization tool development process is presented.

summary	This paper presents an approach to creating an online real time rendering environment, upon which a large-scale, urban 3D model can be produced as a collaborative effort between initial content creators and outside parties with an interest in simulation and visualization. In 2007, the City of Atlanta, Georgia organized a taskforce to provide recommendations on the future development and mobility along the city’s signature street, Peachtree Street. To aid in the visualization of this area, datasets were converted into low polygon textured 3D models for the entire study area. This content will serve as the foundation of a collaborative effort to complete a high quality real time environment. The process for this project will be described and the means to extend the boundaries, maintain, and collaborate with this content will be proposed.

summary	More and more urban designs show the appliance of low-energy techniques. Unfortunately, it is difficult to determine which one of these urban designs has the best results for energy consumption and CO2-emissions because of a lack of methods and techniques at district level. A new energy performance calculation method at district level including aspects like houses, transport and households is presented. In this paper we focus on the critical factors at the building level that should be included in a district data model. Therefore we have executed a screening analysis to indicate what the critical factors are.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	ceramiSKIN: Digital Possibilities for Ceramic Cladding Systems

doi	https://doi.org/10.52842/conf.acadia.2008.292
summary	CeramiSKIN is an inter-disciplinary investigation by an architect and a ceramics artist examining new possibilities for ceramic cladding using digital design and digital fabrication techniques. Research shown is part of an ongoing collaborative residency at The European Ceramics Work Centre. ¶ Ceramics are durable, sustainable, and capable of easily assuming detailed shapes with double curvature making ceramics seemingly ideal for digitally inspired “plastic” architecture. The primary reason for the decline in complex ceramic cladding is that manual mold-making is time-consuming—which is at odds with today’s high labor costs and compressed construction timeframes. We assert that digital advances in the area of mold-making will assist in removing some of the barriers for the use of complex ceramic cladding in architecture. ; The primary goals of ceramiSKIN as they relate to digitally assisted production are: greater variety and complexity, reduced cost and time, a higher degree of accuracy, and an attempt to facilitate a wider range of digital design possibilities through the use of a ceramics in architectural cladding systems. ¶ The following paper begins with an overview discussing double curvature and biophilia in architecture and their relationship to ceramics. This is followed by detailed commentary on three different experiments prior to a concluding summary.

summary	City modelling is a topic which has been on the agenda for a long time. Today crucial questions concerning the creation of a city model are resolved. The vision of the automatic generation of the 3D geometry of a city out of high resolution digital aerial images is a reality now. These new developments decreased the cost for creating and maintaining a 3D city model of a complete city significantly. This paper wants to outline the ‘history’ of 3D city models and show recent developments in this field. An overview about current applications and uses in this field in Austria and the implementation into daily work is shown with examples (Graz and Vienna city models). Additionally the new developments like Street View in Google Earth or Bird’s Eye in Virtual earth are discussed in relation to their 3D ‘relatives’.

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 decision support system developed in this research is aimed to the conceptual scheme of project focusing on infrastructure planning and open space design in the architectural context for housing project. Alternative design sets are provided within the limitations, and possibilities to be further evaluated appropriately. This system helps architects and developers to analyze relationships of physical environment, architectural requirements and the overall of project-related factors with real-time cost estimation. Factors for cost estimation derived from the beginning to the end of project will be manipulated simultaneously. Architects and developers can use this design simulation to address the physical data with real-time cost estimation, provide alternative results, and design evaluation for overall project’s feasibility. The software of our research is not just a tool for design & planning automation in feasibility analysis. It will be an interactive decision support system for both developers and planners aspects. The system was developed by SketchUp Ruby Application Programming Interface. The results will be presented into two ways. Firstly, 2D and 3D modeling will be used for interactive visualization in design and planning of the beginning process. Subsequently, numbers and additional factors in details will be used to show relationship between architectural environment and feasibility-based information to help architects and developers collaboratively analyze the land use planning and open space design for housing project. In evaluation process, the developed software is tested with the project preceding and the future project of Bangkok area under constraints and regulations of Building Control Act of Thailand. In conclusion, this system will make effectiveness in design process and management of the construction knowledge. The decision support systems should be designed to makes explicit use of both planning analysis aspect and knowledge-based decision making.

title	Collaborative Financial Feasibility With CAAD For Residential Development
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 594-600
doi	https://doi.org/10.52842/conf.caadria.2008.594
summary	Computer Aided Architectural Design software is a necessary tool for the architectural design of a visible object or model. In residential development, an estimation of time/cost corresponding to the design is needed in order to complete its successful project. But available feasibility supporting tools usually lacks ability to share their information. To solve this limitation, this research proposes a design of Graphic User Interface (GUI) for collaborative financial feasibility through an architectural design process in housing project. The development of the GUI starts from collecting some information and requirement from National Housing Authority of Thailand. A heuristic decision making approach based on financial analysis are then designed for both design processes and feasibility processes of the project. Finally, design of the GUI is an integration of CAAD engines, design standards and financial feasibility analysis. Proposed GUI for collaborative financial feasibility is also tested and verified with some information from sample past projects of the National Housing Authority. From the experimental results, This GUI allows designers to improve the design of the project in real-time by inspecting the result of their design via the part of the architectural design-oriented GUI called myMonitoring and Scratch Pad. Together with planning, collaborative financial feasibility is focusing on the four main financial parameters which illustrated the possible chance of the project: Net Present Value (NPV), Benefit-Cost Ratio (B/C), Internal Rate of Return (IRR), and Payback Period. The core system was developed on Java Technology such as JSP and Swing empowered by 3D game engine. In addition, “Virtools” as an authoring tool was applied to improve interactive 3D virtual environment and explore rapid online system prototyping.

title	Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
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	Driven by advances in building and information technology and accelerated by the tumultuous period of global economic restructuring that commenced in 2008, architecture and interior design practice is today confronted with the necessity of fundamental change. According to the “Building Futures” group at the Royal Institute of British Architects and US-based “Design Futures Council,” both of which this past year published studies on this very topic, a great deal depends on what happens in China and other emerging markets, where many European and US firms now have offices. And that is not only because these are the most vibrant markets for architecture and design services, but also because the demands placed on practitioners in these markets are fundamentally changing the way buildings are designed and delivered, at home and abroad. Both studies suggest that all sectors of the A/E/C industry will face increasingly fierce competition that will, of necessity, force practices large and small to compete less on cost and more on value. In the very near future buildings and their interiors will be valued almost entirely based on performance—economic, cultural, environmental—and only those firms able to create these and other forms of added value will survive. Disruptive technologies like building information modeling and integrated product delivery will enable all firms, even those competing solely on the basis of cost, to design better buildings and deliver them more efficiently. But in such a fiercely competitive global marketplace, efficiency alone will not be enough to guarantee market viability. The real differentiator will instead be design.

title	The Cost Effectiveness of Typical Materials in Relation to Indoor Comfort of Passive Cooling Strategies Appropriate for Small One Story House in Chiang Mai, Thailand

summary	This study suggests that the appropriate building materials are those most common in a given locale considering simple appropriate natural passive cooling strategies for a typical small one story house to apply toward traditional living. Two different weather conditions, hot-dry and hot-humid, were selected representing seasonal climates. Computer simulations on thermal effect and ventilation were processed by CFD software, FLOVENT 6.1. Ordinary building materials have been chosen to compare relationship between outdoor-indoor temperature differences and their costs. It was found that natural cross ventilation is the best solution for a small one-story house with additional assistance of thermal mass effect. The most effective typical wall and roof materials are the conventional 10cm brick wall and 5mm corrugated fibrous cement roof which give the best performance for comfort at a unit investment cost. Simulated results also showed that the same house with typical horizontal ceiling presents better comfort than non-ceiling case.
