title Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique
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. 491-504
summary Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

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 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).

title Constraint-Based Design in Participatory Housing Planning
doi https://doi.org/10.52842/conf.ecaade.2007.687
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 Holistic Cost-Information Management in Building and Construction

summary In the building and construction industry the need for a more holistic enterprise-overlapping information exchange is obvious. Especially the management of cost-information from the very beginning design-phase to the point of controlling and billing is a very important task. Co-operation between architects, construction companies, engineering consultants, and authorities using digital information exchange becomes a strategic success factor. Solutions which cover all stages of the value creation chain such as e-tendering, cost-estimation, cost-determination, and production must be anytime accessible and platform independent. While the basic conditions of IT-infrastructure (digital networks) are today fully sufficient, the compatibility between the systems and the information to be exchanged represent the largest problem. The main problem is in the range of different systems and various information domains. Transformations and adjustments of the exchanged information still cost nearly 40 % of design and engineering time. Efficient information exchanges require a universal exchange format, which makes the existing systems compatible. This paper describes the German approach for a holistic information exchange in the building and construction industry. Furthermore the new approach to integrate the German GAEB Standard and the Industrial Foundation Classes (IFC) and the possibilities that can be obtained out of this integration will be explained.

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.

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.

summary Residents’ active participation is necessary for a feasible community design from the planning stage to maintenance and management. it is necessary to show information related to a plan efficiently to facilitate understanding, and to consider a plan in a limited time. The purpose of this study is to develop a Community Space Design system (CSDS) that can use GIS data and Real-time simulation, in order to support comprehension of 3D area information during continuous development. Using CSDS, participants were able to treat various GIS data fixed, and a subject called the division and the disaster prevention of a community, which the object ground is holding can be understood visually on the same 3D space as real space. Because their solution was found, the design was accepted quickly.

title Preservation of existing buildings through methods of Operations Research
source DACH 2007, International Conference on Digital Applications in Cultural Heritage, P. 157-175
summary The revitalization of existing buildings is getting more and more important. We are facing a situation where in many cases there is no need to design new buildings because an increasing number of existing buildings is not used anymore. The most ecological procedure to revitalize these buildings would be through a continuous usage and by making few or no alterations to the stock. Thus, the modus operandi could be named a “non-destructive” approach. From the architects’ point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms to converge in a design solution. In this regard, it was examined whether solutions for reuse tasks can be produced automatically by the use of optimization processes in floor plan design. These solutions shall be produced by swapping of existing areas. The objective is to obtain feasible planning solutions by means of these computer-based processes, which will serve the architect as a basis for the further editing of the plans. The methodical basis for this procedure is formed by models from Operations Research. The design of the model developed relates to problems in logistics, for example, the loading in trans-shipment centers. It also has analogies to board games like Chess or Go. These games are based on a specific number of fields or crosses of grid lines which are occupied by various tokens. Occupation is subject to a variety of conditions or rules. Compliance to conditions and objectives is clearly defined by the use of these rules. The analogy to our model is the fixed grid, the limited possibility to occupy fields and the fulfillment of an overall goal, i.e., to win the game. Therefore the model does not alter geometric proportions or locations of rooms but changes their occupancy such that a new usage could be applied to the building.

summary Geographic information systems have long been established as useful tools for urban planning. The aim of this study is to put forward applications of GIS (Geographic Information Systems) to urban conservation in cities with architectural heritage. The study presents a specific database design to be integrated within a GIS, and the methodology of gathering data for such a database. This study concerns Bahrain’s architectural heritage, which includes many significant historic buildings as well as an overall traditional character of Bahrain’s old towns. This heritage is endangered due to extensive new urban development and the general neglect over the past decades. The study also describes an experimental database that is implemented for documenting the urban character of the old towns of Manama and Muharraq. This database was tested during a partial visual survey of Manama. It is hoped that this database will be the nucleus of a long-term process of urban conservation in the Kingdom of Bahrain. The work described here is part of a larger study conducted by the UNDP (United Nations Development Program) and the municipal government in Bahrain. A group of international experts in urban planning, urban design, and historic preservation also presented their own specific recommendations. The author of this paper was responsible for designing the GIS that helps in documenting the historic cities of Bahrain. This report proposes the development of a geographic information system for urban conservation planning. The system supports planning specialists and decision makers in their areas of work, such as the creation of urban conservation zones and redevelopment strategies. The system documents existing structures and their present conditions in order to assist in decisions regarding their preservation, restoration, and possible reuse. Such a system will also help the municipalities in regular heritage management tasks.

summary Although many administrators and educators are familiar with e-learning programs, learning management systems and portals, fewer may have experience with virtual distributed learning environments and their academic relevance. The blended learning experience of the VIPA e-learning project for architectural students offers some innovative insights into experientially oriented educational interfaces. A comparative analysis of VIPA courses and project results are presented in the paper. Special attention in the discussion is devoted to the improvements of e-learning solutions in architecture. The criterion of the relation between the actual applicability of selected e-learning solutions and elements of collaborative educational interfaces with VR are taken into account. A system of e-learning applicability levels in program and course development and implementation of architectural tectonics in courseware is developed from the evaluation process and which contributes to the discussion of future trends in architectural education.

title Developing a New Approach of Computer Use ‘KISS Modeling’ for Design-Ideas Alternatives of Form Massing: A framework for three-Dimensional Shape Recognition in Initial Design Phases
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. 745-756
summary This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial Intelligence and psychology. The research, in summary, investigates and describes: 1) a new approach of computer use contributing to generating design-ideas alternatives of form massing in initial design phases, within a simple way that any designer can understand at single glance, 2) implementation of shape recognition for generative three dimensional forms, 3) function to generate different outputs from different recognition, and 4) case studies introduced through applications and functions of the three dimensional modeling system presented by the research. The research concluded that the introduced processes help the user improve the management of conceptual designing through facilitating a discourse of his/her modeling of design-ideas massing.

summary Building Information Modeling (BIM) obfuscates the role of composition, scale and abstraction by displacing the primacy of abstract conventions of representation with a methodology based on simulation. BIM subverts, while simultaneously clarifying, the holistic relationships of the parts to the whole in the architectural design of form and space. Architectural design education has great opportunity and risk in how it comes to terms with re-conceptualizing design education pedagogy as the profession struggles to redefine the media and methods of architectural deliverables in the age of BIM. The paper examines the foundation issues proposed by Integrated Practice. The paper questions how BIM and modeled simulation of architectural assemblage might transcend current definitions of convention in design and construction representation. This paper explores how the academy might prepare students of architecture for a digital practice that focuses on the virtual building model and database management. BIM and Integrated Practice viewed as provocateurs of design education provide great potential for critical analysis of how architectural design is taught. The associated pedagogies are transforming the way in which architectural education engages issues of design and representation and creates opportunities to question the roles and rules of traditional conventions. The paper seeks to engage issues of design specificity and ambiguity related to the assets and liabilities of digital modeling as the primary means of design and representation that BIM represents.

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 Structuring a Generative Model for Urban Design: Linking GIS to Shape Grammars

summary Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

title Experimental Results in Immersive Virtual Reality (IVR): Searching Critical Design Factors within IVR to Increase Architectural Space Qualities
doi https://doi.org/10.52842/conf.ecaade.2007.091

summary The actual study in IVR (Immersive Virtual Reality) proposes a path which may provide meaningful information about the user’s behaviours and difficulties to articulate in immersive worlds. Beyond it, we are searching for parameters to improve design qualities in such an architectural space. Our interest is to use IVR as a medium to research the quality of spaces in particular the atmosphere of such spaces, on the basis of people’s interest and eagerness. Therefore it is important to comprehend the special conditions of the perception and the behaviour of the user in virtual spaces. The purpose is to understand the influence of an IVR environment upon the human being and to develop motivation for a personal use of virtual space as a learning environment. The aim of the analysis was to explore behaviour patterns in a simulated IVR environment. Moving from the dynamic of space, there arises a personal “space-time-system”.
