title	Object-Oriented Application Development in CAD
source	Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary	This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

title	Ensuring Usability of CAAD Systems. A Hybrid Approach
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 361-374
summary	Many CAAD software prototypes today are developed with the aim to bring research results closer to practice. This paper describes a hybrid approach that integrates an Object-Oriented Software Engineering (OOSE) methodology with a usability analysis methodology—GOMS. This approach is examined through two case studies and has shown promising results. It enables CAAD system developers to be aware of usability issues and conduct usability evaluation as early as the analysis phase of the software development process. Consequently, this may improve the quality of CAAD software systems as well as ensure the usability of the systems.

summary	Architecture is a mixture of art and technique. This implies that the architect deals not only with engineering aspects that can be easily quantified and thereafter processed, but deals with aesthetics as well which is in first place qualitative and therefore rather difficult to estimate and numerically represent. As an example, in such cases, these ‘qualitative quantities’ are expressed in linguistic form which should be somehow expressed in numerical form in order to treat such data by powerful and conclusive numerical analysis methods. Expressions such as: bright colour, light room, large space are some of these examples. These expressions are fuzzy concepts whose actual interpretation is hidden and all of them together attach a qualitative value to a certain space. To deal with such information the emerging technologies of the last decade can provide an important aid. One of them is the soft computing technology that can deal with such soft data. In this paper, based on the case studies, we explain the potential of using soft computing techniques.

title	Smart Objects: Constraints and Behaviors in a Dimensional Design
source	University of Washington, Design Machine Group
summary	Each new design problem in architecture presents a new set of requirements .A designer must remain aware of these requirements and effectively communicate them to collaborators because the degree to which the requirements are met will determine the success of the solution. This thesis explores how design can be effectively presented in a medium that is both explorative of form and descriptive of the design problem’s requirements. To facilitate this, we present Smart Objects, a constraint-based three-dimensional(3D) computer program. In Smart Objects, design intentions of an architectural problem are embedded as constraints into the modeled objects that compose a formal solution. A model is presented through a 3DVirtual Reality Modeling Language (VRML) viewer and constrained by a software program we wrote in the Java language. Both the VRML viewer and the Java program are contained within a single web page. In Smart Objectsd. A designer meets or violates constraints, objects behave in a manner that reflects the requirements of the problem and intentions of the designer. SmartObjects communicates the design principles and guidelines that inform an architectural design to the collaborators involved in the project. It ensures that these principles and guidelines are maintained as the design progresses.

title	The Virtual Campus: A new place for (lifelong) learning?
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 472-477

summary	472 eCAADe 20 [design e-ducation] Modeling Real and Virtual Worlds Session 13 In the early spring of 2001 a collection of German universities founded a virtual faculty of architecture, which was named „Liquid Campus“. Current thinking about future forms of education in the field of architecture combined with over 4 years of experience with net-based design studios, led to questions about the future of existing universities, their buildings and their use. This problem was put to 43 students in the form of a design exercise to create a place for a virtual university. In the current situation, in which the administration of knowledge is more and more located on the internet, and even the so-called meeting places themselves can be virtualised through the help of video-conference-software, the exercise was to design a virtual campus in the framework and to carry out this design work in a simulation of distributed practice. Initial criticism of the project came from the students in that exemplary working methods were not described, but left for the students to discover on their own. The creation of a concept for the Liquid Campus meant that the participants had to imagine working in a world without the face to face contacts that form the basis (at present) of personal interaction. Additionally, the assignment to create or design possible links between the real and the virtual was not an easy task for students who normally design and plan real physical buildings. Even the tutors had difficulties in producing focused constructive criticism about a virtual campus; in effect the virtualisation of the university leads to a distinctive blurring of its boundaries. The project was conducted using the pedagogical framework of the netzentwurf.de; a relatively well established Internet based communication platform. This means that the studio was organised in the „traditional“ structure consisting of an initial 3 day workshop, a face to face midterm review, and a collective final review, held 3,5 months later in the Museum of Communication in Frankfurt am Main, Germany. In teams of 3 (with each student from a different university and a tutor located at a fourth) the students worked over the Internet to produce collaborative design solutions. The groups ended up with designs that spanned a range of solutions between real and virtual architecture. Examples of the student’s work (which is all available online) as well as their working methods are described. It must be said that the energy invested in the studio by the organisers of the virtual campus (as well as the students who took part) was considerably higher than in normal design studios and the paper seeks to look critically at the effort in relation to the outcomes achieved. The range and depth of the student’s work was surprising to many in the project, especially considering the initial hurdles (both social and technological) that had to overcome. The self-referential nature of the theme, the method and the working environment encouraged the students to take a more philosophical approach to the design problem. The paper explores the implications of the student’s conclusions on the nature of the university in general and draws conclusions specific to architectural education and the role of architecture in this process.

summary	Throughout history, profound technological shifts have been accompanied by significant cultural changes. The current shift from a technical paradigm based on physical, mechanical production to one based on electronic media impacts on forms of architectural practice in unexpected ways. The use of design software not only enhances graphic and modeling capacity but also reveals new possibilities for both form generation and fabrication. At a more subtle level it may influence the patterns of thought and creativity that have underpinned traditional forms of architectural practice. This paper examines the implications of the redefined praxis by considering the new role of ‘town and gown’ in the production of the interactive hypersurface: the AegisHypersurface©, the first working prototype of which was unveiled in March 2001.

title	CAD Study in Visual Analysis of the Visual Sustainability for China Urban Natural Landscape Planning
source	Chinese University of Hong Kong
summary	In this thesis a GIS-based CAD system prototype of evaluating visual quality of urban natural landscape environment is presented. This prototype is an indispensable component of the integrative Visual Sustainability research, and offers a calculable and visualizable technique to urban visual natural landscape assessment. This scientific method provides precise data to estimate the visibility of natural landscape in urban construction actuality. Furthermore, it can also work out supporting information for maintaining and protecting valuable visual landscape resources in further planning. Introduction of this methodology intends to improve the natural landscape cooperation in China urban planning through visual protection. Combining with popular CAD software such as AutoCAD and Microstation, the research team uses ArcView GIS software and its 3D Analyst extension to accomplish a set of research procedure, which includes data modification, model making, viewshed and view sensibility analysis. In addition, this system can create simultaneous 3D scenes or hire other information media as reference tools for professional analysis, design consultation and intercommunication. The core technologies of this proposed system are viewshed calculation and overlay analysis. In viewshed analysis, human visual characteristics are simulated by a series of ergonomics parameters of viewpoints. Viewshed of each viewpoint can be calculated into vector data and mapped by polygons identifying which region is visible and which is not. Overlay function of the proposed system is used in visual sensibility analysis to achieve the division of higher visual sensible area which indicates the common visible area from different viewpoints. Additionally, viewshed maps and visual sensibility results can add more information to mark out the areas that can satisfy certain visual parameters such as appropriate visual angle or visual distance. These overlaying results can visualized the visible areas into hierarchical visual perception quality categories in order to define the visual landscape significance of particular planning regions. A case study was operated to evaluate this system. The case is in Zhongshan city, Guangdong Province of China. Jinzishan hill region is the study site that picked by collaborating discussion of research team and the local government. It is located on the edge of urban built-up area. Jinzishan massif is the prominent landscape element of the surrounding environment. There are three topics in Jinzishan visual perception in this paper. The first topic is the visual quality evaluation of the intersections of its surrounding road system. The second is the integrated visual perception of two main roads called Qiwandao and Bo‚Äôailu. Finally is the analysis of the hill skyline visual quality in surrounding area. The analysis results in GIS vector data can be converted into popular data format and combined with other spatial information for practical application. And comments for future urban planning are collected and analyzed by professional responses to the computer-generated information investigation.

summary	One of my tasks while working for Arup in Los Angeles was to teach engineers how to design and communicate using the same tools as architects. As increasing numbers of clients provided us with virtual massing and conceptual models to work from, my colleagues began to acknowledge the need to develop engineering solutions within these same virtual environments. So, my challenge was to not only utilize 3D modeling for visualization but also for design, analysis and production.

title	Integrative Design Strategies for Multimedia in Architecture

summary	Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	THE INFLUENCE OF THE SIMPLIFIED ARCHITECTURAL MODEL ON THE ACOUSTICAL SIMULATION RESULTS
source	17th International Congress on Acoustics, Proceedings : Vol. III - Architectural acoustics - Opera house acoustics - p. 46-47 – ISBN : 88-88387-02-1, 2-7 Septembre 2001, Rome, Italy
summary	The sometimes complex architectural shape of halls creates modelling difficulties as the simulation computing systems need plane surfaces. In order to approach a perfect shape of curved surfaces, a big number of facets is necessary. This poses, as a consequence, computer memory problems which is the case of the horse shoe shaped Opera House with its richly decorated columns, balconies, etc. This paper compares the acoustical measurement results and the calculation results of a computer simulation software applied on several models (from the most simple till the most complex ones) of the Grand Theatre of Bordeaux.

title	Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results

summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	This paper documents an initial study investigating the integration of Computational Fluid Dynamics (CFD) simulation modeling into wind mitigation design for building structures located in wind hazard prone areas. Some of the basic principles and theoretical concepts of fluid flow and wind pressure as well as their translation into design criteria for structural analysis and design are reviewed, followed by a discussion of a CFD application case study for a simulated hurricane force wind flow over a low rectangular building using the k-epsilon turbulence model. The techniques and parameters for development of the simulation are discussed and some preliminary interpretations of the results are evaluated by comparing its predictions against existing experimental and analytical data, with special attention paid to the American Society of Civil Engineers, Minimum Design Loads for Buildings and Other Structures, ACSE 7-98 and the Uniform Building Code .

summary	The idea of the Bauhaus education was born out of the conviction that designs for mass production and modern architecture needed a new fundamental design strategy. Today, seventy-five years later, the modern, basic design pedagogy needs to be revisited, as the impact of the Information Technology Revolution on design practice and education is now extensive. The illustrations and reflections on a modern curriculum for fundamental design and communication presented in this paper are derived from the authors’ introduction of the new media to design studios at UBC and from design practice. In the case of the nascent student of architecture, a different, rudimentary approach is required: one calling for the combining of the modern, basic design agenda with the introduction of the new media. The fundamental digital design pedagogy is young and not fully established. This is a considerable problem, since the practice and learning of architecture today is increasingly aided by and dependent upon digital media. Parallel to the traditional methods, the contemporary student of design is now obliged to engage new and dynamic conditions at the formative stage of his or her education. In the recent past, the computer was considered as just another device, requiring the development of mechanical techniques or skills. While those skills still have to be mastered, more recently in design education and practice, IT has become accepted as MEDIA - not just as a drafting or modeling tool. This process is perhaps due to the rapid dissemination of computing literacy and to the progressive accessibility and ease of use of IT. At UBC, Techniques and the Foundation Studio are introductory courses intended to make students engage the new media in parallel with, and complimentary to, established conventions in design.

source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 667-680
summary	Computational performance-based building design support faces a conflict. It is important to provide building performance feed back to the designer as early as possible in the design process. But many aspects of building performance are significantly affected by the design of the building’s technical systems, which are typically configured in detail only in the later stages of design. The challenge is thus to find a method to use detailed simulation tools even during the early stages of design when values for many of the variables for the building’s technical sub-systems are not yet available. In this paper, we demonstrate how this problem can be partially solved by combining two levels of automation. The first level consists of differential building representation involving a number of domain (application-specific) object models that are derived from a shared object model automatically. The second level uses generative agents that create reference designs for the technical sub-systems of the building. To demonstrate the feasibility of the proposed approach, we use the building energy systems domain (heating, cooling, ventilation, and air-conditioning) as a case in point.

title	Realism vs. Reality in Digital Reconstruction of Cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

summary	Several common phrases, such as “information society” or “virtual reality” point out the fact that information technology, digital tools and numerous different services via various communication networks have become crucially important factors of our western lifestyle and living environment. The trends of the society reflects naturally the working environments of the construction field, architectural discipline being amongst them. It is almost inconceivable to even imagine an architect without computer-based tools anymore. This evolutional development process has, from historical perspective, only recently started. The process is constantly evolving and rapidly increasing our possibilities to use and enjoy these modern digital fruits. The sometimes unpredictable and rapid changes in our working environment should make architects nervous about the impacts of the changes. All those delicate methods and collective traditions of the several thousand year architectural discipline(!), just simply cannot be transferred into the digital realm in a few decades. Researchers and teachers should very carefully, but still open mindedly, critically explore, analyse and adjust the so-called “modern technology” into the world of architecture, construction, design, planning – and education. We are not just “endusers”, It is we, in fact, who should define what, where and how are we willing to use it(IT). The value of information is constantly growing in our society, and in the future it will evidently be even more so. The value of information is quite hard to define with measurable or agreed concepts, but information evidently contains value-factors. The information which the architects are creating, modifying and manipulating, contains essential and valuable core data concerning the whole built environment of our society. It affects the physical surroundings of our society, in which we will be living for decades – hence, the information has a historical basis. The architectural core information also very strongly affects the quality of life of our fellow citizens – consequently, it has deep social meaning. The essentials of architectural information relies on the tradition of centuries – hence, it clearly has acknowledged cultural values, which are also extremely difficult to quantify. So how could architectural information be described? The information covers a wide range of heterogeneous concepts, items, values, methods, tools, materials, true facts, rumours, intuition and knowledge, plus a multitude of yet undefined or unpredictable factors, which still have to be watched and prepared for. Since the information deals with common and general subjects, it should also be described with common and general concepts. On the other hand as the information is also concerned with the minutiae of specific projects, the architectural information should also be described with well identified and unique entities. With our digital tools we handle all information – including architectural – more and more digitally. We have to handle and manipulate information currently as digital data, which could be understood the ”raw material” of architectural information. Digital data becomes valuable information, when some kind of meaning or purpose to somebody can be attributed to it. In the early gloomy days of ”digital architecture” in the 1960’s and 1970’s, researchers tried to describe architectural artefacts and even design process mathematically. The details of architectural information were quite difficult to describe with binary alphanumeric information of main-frame machines. The architects’ tools development then led to a trend where architects could better represent and visualize the design objects digitally. The widespread and common use of 2D-drawing and 3D-modelling tools is still a very strong trend within our discipline. In fact it is “the way” the majority of architectural information is managed today. During the last 15–20 years, so-called conceptual modelling or product data modelling, done in various technical and construction field research units worldwide, has from one viewpoint clarified the basis and essence of architectural information. Hence, it’s not only CAD-software application development, but also elementary and theoretical research that gives us valuable help to survive among the ever growing seas of terabits of data in the future to come. Architectural information is something that simply cannot be described just with DWG-drawings or dummy scanned photographs any more. Although drawings and photos may contain very important bits of architectural documentation, we need ntimes more “complexity layers”, concepts and tools to manage and understand the essence of architectural information today. A proper way to manage the data we are working with, has to cover the whole architectural discipline. The methods and tools also have to be valid and flexible for several decades in the future.

title	New Approaches to 3D Gestural Modeling - The 3D SketchMaker Project

summary	The 3D SketchMaker project has developed two prototypes for a gestural 3D sketching system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The system was conceived to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later using any 3D package. It is, in essence, a 3D modeling system directed to do sketching with hand movements and gestures in a virtual reality environment.

title	Improving design processes through structured reflection : a domain-independent approach
source	Eindhoven University of Technology
summary	In the world of designing, three fields of attention can be recognised, namely design research, design practice, and design education. Gaps exist between these three fields. In this thesis about designing, the focus is on the gap between design research and design practice. Design practice includes many design disciplines and an increasing number of multidisciplinary teams. Main problems in design practice are the communication between designers with a different background and the integration and co-ordination of important aspects during a design process. By tackling these problems, the effectiveness and efficiency of design processes in practice can be improved. The study of similarities and differences between design processes in several design disciplines and the development of support for reflection on design processes are topics that can improve design practice and that deserve more attention in design research. The goal of my research is to decrease the gap between design research and design practice in order to improve design processes. Reflection on design processes can help designers to improve their design process, its results, and the designer’s proficiency: By reflecting explicitly on the current design situation and on the performed design activities, in a systematic way and on a regular basis, designers can plan next design activities that can be performed effectively and efficiently given the design goal at that moment. In this thesis, the combination of systematic and regular reflection is called structured reflection. To improve design processes in various design disciplines in practice, the study of similarities and differences between design processes in several disciplines can be useful. Similarities between design processes are the basis for domain-independent design knowledge (as distinguished from domain-specific design knowledge). To reach the goal of my research, I have chosen to combine, in a broad explorative study, the development of support for structured reflection on design processes and the development of domain-independent design knowledge. This thesis describes a domain-independent approach to improve design processes through structured reflection. My research process can be summarised as follows. I studied three design disciplines, namely architecture, mechanical engineering, and software engineering. To get input from design practice, I did qualitative empirical research: I performed twelve case studies in the three disciplines to inventory characteristics of design processes and I compared the cases for similarities and differences. The similarities, together with the results of a literature study, have been the basis for the development of domain-independent descriptive design knowledge. The developed descriptive knowledge, in turn, formed the basis for developing domain-independent prescriptive design knowledge. At the end of the project, I confronted all results with design practice to get feedback on the results in another empirical study and I performed a literature study to position the results in the design literature. My design philosophy and design frame are the descriptive results developed to answer the first research question, namely “How to describe design processes in a domain-independent way?”. My design philosophy is a set of domain-independent concepts and terms for describing a design process. The concepts and terms are based on an application of the general theory of state-transition systems to the context of designing; the concepts of state and state transition correspond to the main concepts of design situation and design activity in my design philosophy. The answer to the first research question given by the design philosophy is refined in a design frame: The design frame offers a means to structure the description of a design process in a domain-independent way. Major structuring concepts of the design frame are dimensions and subjects. I define three dimensions, namely level, perspective, and time. These dimensions define a three-dimensional space, called a positioning space, in which important aspects of design processes can be positioned. A positioning space must be defined for each subject, being the three parts of a design situation: the product being designed, the design process, and the design context. My design frame is a domain-independent structure formed by the combination of the three dimensions for each subject. My design method is the prescriptive result developed to answer the second research question, namely “How to support structured reflection on design processes in a domain-independent way?”. My design method is a domain-independent aid that offers designers support for reflecting on design processes in a structured way. Reflection on design processes is defined as an introspective contemplation on the designer’s perception of the design situation and on the remembered design activities. A reflection process is described as a process that consists of three steps that are called preparation, image forming, and conclusion drawing. The design method is based on two main concepts: The first concept is the systematic description and analysis of design situations and design activities by means of forms and checklists; only systematic support for the preparation step of a reflection process is developed. The second concept is the idea of design sessions, introduced to stimulate designers to reflect regularly during a design process. A design session is defined as a period of time during which one or more designers are working on a subtask of a certain design task, for example, one afternoon, a whole day, or a week. Both concepts are combined to support structured reflection on design processes. The complete design method consists of five steps for each design session, namely planning a design session, defining the subtask of the design session, reflecting at the beginning of a design session, designing during the core of a design session, and reflecting at the end of a design session. A prototype software tool, called ECHO, has been developed to explore the benefits of using a software system to facilitate the use of the design method. Together, the design philosophy and the design frame offer concepts, a vocabulary, and a structure to describe design processes in a domain-independent way. The design method is a first proposal of a method that supports structured reflection on design processes. My results are thus possible answers to the mentioned research questions and are starting points to improve the effectiveness and efficiency of design processes. Based on the feedback I collected, I am optimistic about the applicability of my results in design practice. By asking input from design practice and by developing results that are useful for design practice and that contribute to design research, I contribute to decrease the gap between design research and design practice. The most important recommendations for further research are to test all results extensively in design practice and to investigate how to apply the results in design education.

summary	This paper evaluates the integration and use of ECOTECT, an environmental prediction software package into teaching within the authors’ school of architecture. ECOTECT is relatively unique amongst performance analysis tools in that it is aimed primarily at architects and is intended for use during the earliest, most conceptual stages of design. It integrates a relatively simple and intuitive 3D modeling interface with a range of analysis functions.
