title	Constraint-Based Design in Participatory Housing Planning
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 687-694

summary	The research presented in this paper deals with the yet unexplored development of a constraint-based design strategy to support participatory housing planning processes in Latin America. The article discusses the implementation criteria of a constraint satisfaction approach to solving the building bulk design problem. This elementary problem to the architecture practice, is concerned with the synthesis of the boundary geometry from the volume, shape and allocation of the building and any part thereof located inside a given zoning lot. A legal solution to a building bulk design problem is a building cubature that complies with all the applicable bulk regulations. The case study applies to the common class of single-family house units produced in Chile and the regulatory framework implemented there. Two different computer implementation criteria are being tested in an ongoing series of trials. The first, and most extensively developed, makes use of Maxon’s XPresso® visual scripting environment to set up a semi-automated controllable design environment that allows to create parametric feature-based 3D models of building bulk solutions. The second approach is currently being tested by using Ilog’s OPL Studio® constraint programming environment to achieve fully automated search and 2D graphic visualization of the complete set of solutions to separate subdomains of the bulk problem.

title	The Adjacency Topological Model for Housing Layout and Its Generating Algorithm, Based on the Case Study of Chinese Apartment Layouts Since 90s
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.r9v
summary	Our research deals with the problem of space layout planning and chooses the Chinese apartment layouts_since 90s_ as our case study objects. A new kind of data structure for building layouts is proposed which records the adjacency topological information of layouts. The most important quality of our model is that its phenotype corresponds to our visual perception about space layouts which makes possible the morphological analysis and layouts generation. Based on constraint satisfaction techniques the Generating Algorithm focused on enumerating all the possible topology models, under the constraints of program for a new housing layout design. A case study is presented before the conclusion is given.

title	Simulation Software Development for Urban Landscape Possibility Analysis
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.u9u
summary	This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

title	Web Based BIM for Modular House Development: Query Approach in Consumer Participatory Design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 559-570
summary	The paper describes the relationship of client’s requirements and available design options of the proposed system by examples of its current prototype. By integrating the nature of modularity in prefabricated housing design, a proposed web-based design system will provide information filtering questionnaires to assist customers in selecting appropriate design components. A methodology has been developed that can generate design options based on the client’s needs and available modular components from selected product suppliers making it possible to simulate the final design before processing orders for assembling and manufacturing. Overall, the research demonstrates the power of internet that acts as a feedback loop to receive the information from clients, streamline the communication in between design teams, and integrate all products and materials together.

title	Temporary Housing Design and Planning Software for Disaster Relief Decision Support System
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k9q
summary	There is a continuous and urgent need for disaster relief in Thailand and countries suffering from floods and tsunami impact. Based on this issue, design and planning software for temporary housing project has been developed, as well as the process and guideline for implementation. This paper describes a unique coupling of interactive 3D virtual environment with parametric designing in order to manage disaster relief project more efficiently. Architects and planners can use the functionality of software on both design simulation and project evaluation aspects. We need to provide correct information to help people making decision when they are in disaster. So the disaster relief decision support system must offer proper information of crisis management focused on people, place, and process. One of the main features of software is the relationship modeling of essential factors such as number of people, houses, budget, time, and space. This automatic temporary houses generation and space planning is simulated for land use and layout plan design with cost estimation analysis. The system components were proposed to a new disaster relief system in alternative approach. Using community-based development will not cost budget but required people participation. Our software’s space coordination will start and centered from available space in school or temple with sufficient infrastructure. After essential factors are inputted, appropriated number of temporary houses, public facilities, and management guideline will be generated to support further planning decision. Our core system was developed on Java and Swing Technology, empowered by real-time 3D rendering CAD engine. In addition, “Virtools” as our Authoring Tools was applied to improve design interaction and explore rapid software prototyping. At the end, we discuss the comparison between real situations in Thailand and appropriate design standardization, which should be reconsidered how to manage crisis with the limitation of time and budget from government.

title	Generative Systems Based on Animation Tools: Structure and Form of Core Ideas in Architectural Design
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k1h
summary	The goal of the research described in this paper is the formulation of a generative system for architectural design, where a structured core architectural idea is the input and alternatives to that idea are the output. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. Initially the designer shapes an idea using animation software tools, where each tool is actually a constraint or a grammar rule defined informally by the user/designer. The influence of the tools can vary according to time, speed, location, configuration of the object and/or the constraint itself. In some of these animations the designer has the ability to sidestep partially the issue of emergence by providing specific key - frames for the solution to follow. The use of animation tools [shape driven curves, speed and time-line functions, parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established : the animated schema may be either a sum or a family of various designs or the animated time-line may represent a single design which changes over time. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

title	Delivery Types And Communication Modalities In The Flat-Pack Furniture Design Critic
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, today’s computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text; whereas studio teachers critique by interpreting the student’s design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004; Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991; Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

title	Materializing Design: contemporary issues in the use of cad/cam technology in the architectural design and fabrication process
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 317-326
summary	While the ability to produce and quantify design and fabrication information has been greatly enhanced by advances in CAD/CAM technology over the last several decades, a practical link between what can be modelled virtually and what can be built physically has yet to be realized. The process of parsing complex design information and translating it into a format that can be utilized by those responsible for its fabrication is a many-stepped process, in some cases made increasingly difficult by the same technology intended to simplify the process. The use of CAD/CAM technology in the architectural design process requires ongoing consideration as its use becomes increasingly pervasive in the design process. Within the context of contemporary architectural practice and discourse, what is the degree of fidelity between design information and fabrication information? How are advances in accessibility to, and the capability of CAD/CAM technologies affecting the role of the architect in the overall building process? Does CAD/CAM offer unique and undiscovered possibilities to re-associate the designer with the builder, or simply a process of more efficiently automating the design and construction process? Our work builds upon issues of the fundamental differences that CAD/CAM technologies introduce to design practices; issues that were raised at the very outset of CAD/CAM’s introduction to architectural design. Employing parametric design software, we design and construct a speculative façade system for a high-rise tower which is then fabricated at a reduced-scale with various two-axis CAM technology. We use relational and constraint-based logics in order to create models of parametric assemblies of discrete components which are translated into machine-ready formats, fabricated and re-assembled, in a process modelled on that typically followed in the construction of a real building project.

title	A System for Providing Customized Housing
source	Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 153-166
summary	This paper describes a system for generating customized mass housing. The aim is to provide dwellings at an affordable cost with recourse to mass production and yet guarantee that they are tailored to their users. It combines two systems, a rule-based design system and a prefabricated building system. The integration of both systems is achieved through the development of a computer tool to assist designers in the various stages of the housing design process. This tool produces three kinds of outputs: three dimensional models, construction drawings, and a list of construction elements, including their cost and information for manufacturing.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Sustaining Design Decision Makers in the AEC industry
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.w3a
summary	Today’s typical decision making problem such as strategic planning, portfolio analysis, resource allocation and human resource management involves a variety of tangible and intangible strategic goals, conflicting constraints, dozens or hundreds of alternative initiatives to be pursued, and limited resources. A decision maker cannot meaningfully combine all of this information to make right decisions. To sustain decision makers in the Architecture, Engineering and Construction (AEC) industry, this paper proposes a tool to transfers a complex problem into a concept of hierarchical structure consisting of goal and its criteria and sub-criteria. Irrespective of the applied domains, this tool provides a flexible means for tackling the complex decision making process. It embeds a mathematical model for prioritization and decision making which is based on the Analytical Hierarchy Process (AHP).

summary	By integrating the nature of modularity in prefabricated housing design, a web-based design advisory system provides interactive questionnaires to assist customers in selecting appropriate design components. The prototype model combines the result of client’s requirement input and design configurations of a modular system. The digital model is created by Building Information Modeling (BIM) applications to streamline the delivery process from design to manufacturing. Finally, the BIM design model can be reviewed via Google Earth before sending the ready-to-build digital information model and building specifications to the collective manufacturers and suppliers.

doi	https://doi.org/10.52842/conf.ecaade.2007.335
summary	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

title	Digital Masterplanning: Computing Urban Design
source	In Urban Design and Planning: Institution of Civil Engineers, Thomas Telford Publishers, ahead-of-print
summary	The digital revolution has finally reached urban design as one of the last design communities not very familiar with computing. This is despite the city and geography being the natural fields for systems analogy and digital models of mathematical and statistical simulation were developed in the 60s and 70s for urban planning, much before industrial or architectural design. The recent arrival of urban design simulations is however not as innovative and radical as their 50 year old counterparts since they use computing solely for policy visualization, quantity evaluation or pattern generation. The Computational Design and Research Group [CDR] at Aedas\|R&D started in 2007 to develop an open platform of lightweight applications – Digital Masterplanning – in collaboration with partners from academia and industry to provide methods for urban design, based on computational methods called meta-heuristic algorithms. An attempt to encode empirical knowledge and design assumptions into simulations is described where designers can assemble the resulting applications according to scales and brief into custom workflows.

summary	The objective of the paper is to demonstrate the application of architectural research and design methods from the fields of strategic design, digital production and design chains to facilitate the completion of demanding large-scale building projects. Since we have concentrated the efforts of the past few years on various aspects of building practice while applying and testing the “Digital Chain” method to several concrete projects, we are now engaged with linking the individual phases in order to make the final step towards the reality of building practice. With this knowledge, we attempt to propose a new way of thinking in the design and building sector based on digitized planning processes.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary	The use of Internet communication technologies in distributed teams has been carried out for well over 10 years. In this time, various methods to communicate and transfer information have been developed. A large amount of effort has been placed on enabling normal conversation to take place and it could be said, that with technologies like Skype, this is established. This enables planning partners to discuss, but we still need to convey what they are discussing. In short, the contents are still lacking. Technologies exist to allow users to share files or images, however this does not nearly reach the intensity or quality of discussions when partners are sitting together in front of a drawing or model. At best, screen sharing allows participants to see the same image but with low resolution and bad system response. The goal of the Intervision3D project is to allow distributed team members to discuss design issues with a common 3D model where participants can manipulate the model together in real time. In contrast to screen-sharing solutions, the Intervision3D project uses a server, which delivers a copy of the model to each conference participant. The server then coordinates the perspective views of all conference participants. One of the participants (usually the first) is initially designated as the speaker and he or she controls the views of the model through an intuitive walk/fly-through interface. The speed of the system is also buttressed by the simplicity of the application: as a Java applet, it is possible to start the Intervision3D system in any browser or as a separate applet on any system. As such, none of the participants need to install anything. The resolution of the model is optimized for each participant's browser and computer display. Currently, Intervision3D can import .3ds files and then render them using the JOGL Engine (Java Bindings for Open GL). JOGL allows the full Open GL suite to be used in rendering the model including lighting and textures: even normal PCs can do this quite well. The first implementation of the system is within an existing internet-based Design Studio and the paper elucidates how the first uses of the system have (partially) helped to increase the exchange of design ideas over the Internet. Through the Intervison3D system, the participants who have been separated by distance can once again discuss the same 3D model.
