title Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
summary The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

title Sketch-Trigger: A Specification for a Form Generator and Design Analysis Toolbox for Architectural Sketching
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In order to develop design and decision support techniques in the early sketch design phases, weshould (1) experience and (2) observe real behaviour in practice, (3) transform observations intoideas for improvement, (4) develop behaviour models to explain the sketch design activities and(5) to evaluate between the proposals, (6) decide between the alternatives, (7) implement theselected option in a supporting tool. Our paper reports about the results of step 3 in particular inthe first phase of a Ph D project, started this year. Our main objective is to amplify the effects ofthe sketch as a very effective instrument to generate original forms and to stimulate the mind to discover new shapes and meanings in the roughly sketched patterns. Instead of considering the sketch only as a representation of what the designer has in mind as is usually assumed in CAD systems, we see sketching as form activation. Thus, we want also to offer triggering images to spark off the imagination of the designer while generating images which are practically impossibleto create by hand and certainly not at short notice. The main improvement proposed is the use of an evolutionary form breeding system: one or more sketched parent images (either ready-made'partis' or basic schemes drafted by the designer) presented in the centre of the screen, will generate surrounding mutated children as defined at random but constrained by default or customization of the available transformations. By selecting one or more children a next generation will be produced in the same way. At all times the designer can introduce or reduce constraints. To complete the usually offered 'classical' symmetrical, spatial and logical operations,we want to introduce dis-functional operations like dislocation, explosion, deformation, anti-logic etc, in short all kinds of antagonistic operations, among them the transformations applied indeconstructionist and post-modern design. Our expectation is that these operations will correspond roughly to the 'move' pertaining to a design entity as the operational unit most appropriate for design behaviour research, in particular the analysis of the chunking and parsing behaviour of the designer. The applicability of the 'move' approach has been shown experimentally by Habraken and others. Goldschmidt has abandoned the usual typology approach of protocolanalysis based on moves and concentrated on the linking of moves, but has been hampered by the lack of a good representational instrument. This brings us to the representation of moves and linkages as a research instrument. The 'linkograph' approach as proposed by Goldschmidt is a first step towards a graphical representation of the designers associative reasoning mode, necessary for tracking the heuristics of designers at the most basic level, but its practical implementation remained as yet incredibly laborious. What is proposed here is an instrument and approach which makes such registration and analysis possible within a structured software environment.

title Immersive Drafted Virtual Reality a new approach for ideation within virtual reality
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 304-316
summary There is a void between design and computer in ideation. Traditional tools like sketching are more appropriate for conceptual design since they can sustain abstraction, ambiguity, and inaccuracy—essentials at the beginning of the design process. Actual graphical user interface approaches, as well as hardware devices, constrain creative thinking. Computer representations and virtual reality are now used for presentation and validation rather than for design. Most virtual reality tools are seen as passive rather than active instruments in this process of ideation. Moreover, virtual reality techniques come from other disciplines and are applied to design without considering the design process itself and the skills designers already possess.This paper proposes and evaluates a new approach for the conceptual design of spaces within virtual reality. Starting from the non-immersive technique we developed before, where the user was able to be inside a 3D modeled space through real sketches, this technique goes one step further, allowing the designer to sketch the space from the inside all in real-time. Using an interactive pen display for sketching and an immersive projective spherical display, designers and colleagues are able to propose and make design decisions from inside the project. The capabilities of the computer to display the virtual environment are, therefore, mixed with the designer’s skills in sketching and understanding the space.

title HYBRID MODELING: MANUAL AND DIGITAL MEDIA IN THE FIRST STEPS OF THE DESIGN PROCESS
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 819-827
summary This paper proposes a new paradigm in computer-aided design: hybrid modeling. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this paradigm fuses the two and proposes a new technique that uses the performance of the digital with the capacities of the analog without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. Furthermore, two principal elements must be considered in the design process: shape and space. These aspects need to be approached with convenient tools that are adapted to the designers. This new paradigm is presented through two new innovative techniques: the hybrid mock-up (for shape) and drafted virtual reality (for space). A review of the implications of this paradigm on the design process is presented. Not only are the techniques fast and easy to learn and execute, but the results demonstrate that the designers can express both their individuality and the idiosyncrasies of their personal representations; important elements that are difficult to achieve with conventional 3D modeling techniques, especially during the primary stages of the design process.

title A Web-Based Approach to Transferring Architectural Information to the Construction Site Based on the Bim Object Concept
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 613-622
summary The current means of transferring architectural data to the construction site depends mainly on the drawing either manually or electronically drafted both in physical or digital formats. The printed or manually drafted drawing is being replaced with the digital version that can be accessed with a PDA. There are many benefits of the digital form over the physical form. However the full potential of this medium has not yet been fully exploited. The new CAD paradigm, BIM (Building Information Modeling), suggests that all the building information can be represented as a digital database that constitutes the information about the building elements as three-dimensional geometry, as well as, properties and specifications in the form of objects. This paper describes the process to convey the information about the CAD objects to the construction site through the web by extracting the properties of the objects into an XML file which can be queried for the needed data.

summary The aim and object of this account is to elaborate on the role of eCAADe within the present worldwide "CAAD-activities". Each of the associations dedicated to the field of CAAD has taken its very own course of development, many cases of overlap and interaction have resulted, some of them, however, merely based on personal contacts. The purpose of eCAADe is to promote the sharing of ideas and collaboration in matters relating to Computer Aided Architectural Design. This, jointly drafted paper outlines these global aims within a worldwide context. The eCAADe umbrella covers both Europe and its periphery. Including the Middle East and North Africa. Though this does not apply as a kind of "territorial claim ", the primary affiliation of regions to at least one of the current international associations is sought. Historically, the early eighties are to be regarded as the period of first encounters with computers of larger proportions of people involved in architecture, simultaneously with the rise of personal computers. Thus various university sites acted as the forerunners in this field. Implementation of CAAD in teaching and research soon called for channeling the exchanges of experience via a suitable platform. The founding of ACADIA (the North American Organisation) in 1981, however, seems to have set the stage, as shortly thereafter the foundations for a European movement were laid.

title Drafted Virtual Reality - A New Paradigm to Design with Computers
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 829-844
summary This paper proposes a new technique for designing spaces, called Drafted Virtual Reality (DVR), to be used in interior, architectural or industrial design. It proposes the construction of virtual panoramic environments through the QuickTime VR (QTVR) Panorama platform (Apple), starting from sketches made by hand using traditional pen-on-paper techniques. To construct these drawings, the designer uses the computer to build a graphic panoramic template. Using this technique, the designer takes advantage of both approaches, the capacities and possibilities of the computer using VR (3D environments, interaction and real-time), and those of free-hand sketches (abstraction, inaccuracy and ambiguity). These last elements are essential for the first steps of the design process in contrast to the conventional techniques of 3D modeling interacting with mouse and menus. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems very different than how designers actually work. The DVR doesn’t try to simulate analog tools by computers (digital pens), but takes advantage of hand drawn sketches created using analog techniques that are already known by designers and improved by VR visualization. A review of the implication of this technique on the design process. Not only is the technique fast and easy to learn, the results show that the designer can express their individuality and the idiosyncrasies of their personal sketches; important elements hard to achieve with conventional 3D modeling techniques. Finally, this technique can be perceived as a new paradigm in the way we work with computers in design. The limitations of interfaces and usage of current technology are seen when the designer outputs information from the system to process using other analog techniques. The proposed solution marries the existing competencies and techniques of the designer with the advantages of the computer processing. The quality of the virtual experience of this technique is consistent with current designer’s intentions within the traditional design process.
