title Does Color Have Weaker Impact on Human Cognition Than Material?
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. 373-384
summary This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants’ perception, and (2) what possible factors in the built environment would affect occupants’ cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.

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 Integration of 3D Tool with Environmental Impact Assessment (3D EIA)
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. 51-66
summary Environmental Impact Assessment (EIA) tools have been available for some years now and their function is predominantly to predict and identify the environmental impact of building projects. However EIA analysis is often done after the completion of the project or building and when it is too late to influence the design, materials or components to be used. Also, more than 80% of the design decisions that influence the whole life cycle of a building are made at the initial design phase. EIA does not receive the required attention. A new approach is suggested in this research to ensure that designers, clients and stakeholders have all of the relevant information needed at the outline design stage for the assessment of cost and environmental impact. The idea is that building owners and users will have the opportunity to minimise their operating costs from ‘cradle to cradle’. As energy resources reduce over the next few decades, the value of this research will increase and it is possible to foresee government legislation which drives building construction in this direction. By making environmental impact analysis readily linked to 3D products at the very early stage of the design process, the value of 3D technology will be enhanced significantly resulting in more use of the technology in the construction process. In this context, the objective of this paper is to introduce and explore approaches for developing integrated 3D- EIA, LCA (Life Cycle Analysis) and LCCA (Life Cycle Cost Analysis) and VR (Virtual Reality) tools and develop trade-off analysis to assist in the decision making process. To demonstrate initial results, a pilot case study in the UK is being developed.

title The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

summary In the last twenty years, computer tools have progressively enabled the modeling of buildings and cities in lesser time and cost, along with an increase in the results quality. A city modeled according to planning regulations usually present a correlation between plots and buildings dimensions. The representation of such correlation for a large number of plots requires repetitive work, thus suggesting the use of a computational tool to perform the task. Existing CAD, GIS, and VR software can generate accurate representations of the reality, but have no capabilities to simulate the impact of alternative urban regulations for large number of plots in a short period of time. CityZoom is a Decision Support System for urban planning, with a specific built-in city model, where data is represented in an object-oriented model representing the urban structure. CityZoom not only provide CAD tools, but a shell where different performance models can operate iteratively. It can simulate given urban regulations applied to a set of urban plots, as well as address environmental comfort issues such as shadow casting between buildings. Results can be displayed as tables, graphs, and in a 3D preview of the whole city or part of it. It’s also possible to export them to commercial GIS tools, to perform different data analysis. The graphical outputs make for an easy understanding of the results by laymen, an important feature for participatory planning, while the display of the correspondent numerical data enable correlations with indicators and parameters of urban quality.

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process in and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process in and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of this as prototypes. This paper describes the goals of the “Spatial Augmented Reality for Architecture” project and discusses possible fields of application for SAR for supporting the design process in existing buildings from a user’s perspective. This paper presents the initial results of the project, the development of a cave-like hardware and software concept called “low-cost projection in room corners” and the description of the core concept based on a client-server architecture. The project is funded by the “German Research Foundation (DFG)”.

summary There has been a growing research interest in investigating techniques to combine real and virtual spaces. A variety of “reality” concepts such as Virtual Reality and Augmented Reality and their supporting technologies have emerged in the field of design to adopt the task of replacing or merging our physical world with the virtual world. The different realities can be tailored to enhance comprehension for specific design activities along a design life-cycle. This paper presents state-of-the-art applications of these “reality” concepts in design and related areas, and proposes a classification of these realities to address suitability issues for the effective utilization of the concepts and technologies. Their potentials and implications in certain design activities are also discussed.

A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process with and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of it as prototypes. The paper focuses on one aspect of the research project – designing with images in an AR-Environment. The paper presents an overview of the project, a description of the core model based on a client-server architecture, the historical / theoretical architectural background and first results of this research part. The project is funded by the “German Research Foundation (DFG)”.

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.

summary In this paper evolution of CAAD teaching at architectural faculties will be presented. The CAAD will be considered as one of the components of skills and knowledge needed to support Design Studio. The paper is focused on the question “How architectural design may be combined with CAD teaching?” Formulation of this question results from opinion that position of CAAD in teaching of architectural design curriculum is different than other disciplines being taught at architectural schools. Introduction of CAAD to teaching schedules unquestionably and explicitly uncovered the need for changes within the whole schedule of study. Although great number of computer equipment is used, the students are still being taught as in the XIX century. In terms of achieved results it proves ineffective. Analyses have shown that evolution of teaching methods may be divided into four stages: software teaching, “personal involvement”, “replacement” and integration.

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 “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ 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’s 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.

summary The current research we are conducting refers to a general model of architectural design. The complexity of the present-day design process is such that new ICT tools are required to consciously and appropriately govern the design choices. In particular, the tools that involve the early phases of the design process, when the choices crucial to the entire building process are made. In this perspective we are developing, together with a general model of architectural design based on Collaborative Design (CD), a simplified version of it – the _-House game – that can be used to help university students appreciate the complexity of doing architecture and building. This “simplified version” of the general model is therefore a useful ‘design training tool’ in the case of complex problems that can be solved by means of iterations, trade-offs, creativity, and group work; and at the same time makes it possible to highlight, define and link relatively little known aspects of design, such as scheduling, relations among operators, decision-making mechanisms, and process and design priorities.

summary In any built environment, there exist certain subtle stimuli that affect the occupants’ cognitive processes and performance. This research intends to identify: (1) what environmental stimuli an office building would generate that could affect the habitants’ cognitive ability, and (2) how the habitants react to these stimuli. The goals of the study are to develop a new method for using immersive virtual reality to represent a built environment for simulating environmental impact, and to discover factors that could influence habitants’ cognitive performance in a space. It is expected that the discoveries could advance the application of virtual reality to study human cognition in architecture.

summary Shape grammar has been shown to be a frame of work applicable to design issues in various fields. Almost all published grammars work only on the bottom level of shape replacement, however in practice, when using grammars to generate designs, the designer may work on different levels of abstractions, concerning about the hierarchy of the design as well. This suggests that, to make the generating process more coherent, the grammar itself need be able to work on different levels, too. This paper introduces the research work that aims at proposing a set of guidelines for writing shape grammar with which the designer could write structured shape grammars that will be easily automated for generating designs.

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 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.

summary This paper presents the results of an ongoing research on computational methods for the design of theatrical spaces. We demonstrate a systemic approach to design supported by a set of digital tools implemented for assisting the process. The primary purpose of the framework is to establish a formal basis for expressing and exploring explicit design criteria. At this stage the framework enables us to metrically access a range of design metrics that traditionally have been addressed through primarily architectural narrative. Moreover, our method strives in establishing a background where knowledge can be explicitly encoded and the results of analytical methods can be additively employed. In the future, the framework will assist as the platform for experimenting with generative or query-based design processes empowered by computation. We structured this paper / framework around three conceptual units: (a) a design intent toolkit assisting the processes of rapidly generating theater configurations; (b) an analytical system that evaluates a range of design metrics centered about aspects of visual comfort; and (c) a post-processing and visualization unit that binds the design metrics with existing data / studies and provide a range of representation methods. Overall, the methodology adopts existing knowledge in theatrical design, challenges traditional ideas of understanding the theater and proposes methods for evaluating its architectural performance. The conclusions focus on highlighting both the limitations and the potential of our system in the process of theater design. We also extend outside the boundaries of the current research into a brief discussion on the methodological impact of digital technology in architectural research. Finally we propose areas of future research and development.

summary This paper describes the use of parametric methods in generating conceptual designs of high-rise buildings. We first assess current conceptual design practice at a leading AE firm and illustrate the challenge of satisfying a complex set of requirements with the tools currently used by the AEC industry. Few design options are generally developed and analyzed; better design solutions are most likely being overlooked. Parametric tools can potentially help address this problem by allowing designers to formalize and generate solution spaces that can be explored. But few case studies exist to document the construction and impact of these models. We present such a case study. We describe the variables, constraints, components, and rules in the model. We discuss the costs and benefits, and conclude with recommendations for expanding the use of parametric methods.

title Road hierarchy and speed limits in Brasília/Brazil

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,
