summary	As tools, techniques, and technologies expand design practice, there is likewise an innovation in design teaching shifting technology from a means of production and representation to a means of discovery and development. This has implications on studio culture and design pedagogy. Expanding the skills based notion of digital design from know-how, or know-how-to-do, toward know-for, or knowledge-for-action, forms a synthetic relationship between the skills necessary for action and the developing motivations of a young designer. This shifts digital design pedagogy to a medium of active inquiry through play and precision. As digital tools and infrastructure are now ubiquitous in most schools, including the increasing digital material exchange enabled through laser cutters, CNC routers, and rapid prototyping, this topic node presents research papers that engage technology not simply as tools to be taught, but as cognitive technologies which motivate and structure a design students knowledge, both tacit and explicit, in developing a digital and material, ecological and social synthetic environment. Digital fabrication, the Building Information Model, and parametric modeling have currency in architectural education today yet, beyond the instrumentality of teaching the tool, seldom is it questioned what the deeper motivations these technologies suggest. Each of these tools in their own way form a synthesis between representational artifacts and the technological impact on process weaving a wider web of materials, collaboration among peers and consultants, and engagement of the environment that the products of design are situated in.If it is true that this synthetic environment enabled by tools, techniques, and technologies moves from a representational model to a process model of design, the engagement of these tools in the design process is of critical importance in design education. What is the relationship between representation, simulation, and physical material in a digitally mediated design education? At the core of synthetic pedagogies is an underlying principle to form relationships of teaching architecture through digital tools, rather than simply teaching the tools themselves. What principles are taught through teaching with these tools, and furthermore, what new principles might these tools develop?

title	Building Information Modeling: Interactive Versioning Experiment
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 540-541
doi	https://doi.org/10.52842/conf.acadia.2006.540
summary	Interactive Versioning, is the first experiment of an ongoing investigation into the conceptual role of parametric modeling in the design process. In this case, the form is defined by constrained floor-plate relationships. Originally testing methods using numerical values exported to excel, we obtained undesirable results and shifted our focus to the creation of an interactive model; restoring the direct influence of user input. The result is a 10-floor structure that allows the user to tweak point locations along the slab perimeters that in turn have global effect on the overall geometry of the architectural body. We are using four point definition types: reference above, interactive reference, reference below, and independent value. Interactive reference points use referential constraints defined as x and y distances from the global origin, which change on account of user inputs. Reference above points pull (x,y) values from an interactive point above. Reference below points pull (x,y) values from interactive points below. Independent points are unaffected by changes in any of the other points but may also be tweaked to adjust a form. On any given level, there are 2 interactive reference points, 2 reference above points, 2 reference below points, and 4 independent points. Additionally, 2 length constraints link interactive points with reference above points on the same level. This allows for changes to affect the entire structure rather than only the floor plates immediately above and below a given change. The addition of constraints to the floor outlines will yield a variety of formal results and offer the possibility to further control the output.

title	Parametric Modeling as a Design Representation in Architecture: a process account
source	Third CDEN/RCCI International Conference on Education, Innovation, and Practice in Engineering Design, Toronto, ON, Canada, 24-26 July 2006. Canadian Design Engineering Network. Published on CD.
summary	Disciplines outside of engineering, for instance, architecture, are adopting parametric modelling as a design representation. This paper reports on three aspects of the adoption process, which is largely being conducted through multi-day workshops outside of formal university course settings. Fist, the structure and process of such workshops may be a model for interdisciplinary learning and university-industry liaison. Second, students learning parametric modelling must master skill different from that required for non-parametric representation. Third, the parametric modelling strategies being developed in architecture may have both similarities and differences to those used in engineering.

title	Design Informatics: a case based investigation into parametric design scripting and CNC based manufacturing techniques
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for manifesting complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This designresearch approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. A pattern of points attained from this intersection: ‘the point cloud’ serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed scriptroutines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct thus enabling timely and effective construction of the conceptualized form.

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
doi	https://doi.org/10.52842/conf.acadia.2006.232
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	The Autopoiesis and Mimesis of Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The use of digital technology in architecture has proven to be more assertive than originally thought: it has reconditioned the nature of the design process, and established new practices and techniques of fabrication. The 21st century began with the technology of art. There is a new responsiveness to the reading and understanding of digital space, which is characterized by complexity and the uncanny. Recent applications in digital technology show inquisitiveness in the contentious subject Genetic Algorithms. This new architectural process is characterized by two main shifts: from poiesis (or poetry) to autopoiesis, and from authenticity to mimesis. Since evolutionary simulations give rise to new forms rather than design them, architects should now be artists and operators of both Inventive and Systematic design. Inventive design: The digital media should bring about poiesis (poetry). Digital spaces reveal and visualize the unconscious desires of urban spaces and bring forth new dreamscapes, mysterious and surreal. This implies a Freudian spatial unconscious, which can be subjected to analysis and interpretation. “Space may be the projection or the extension of the physical apparatus”, Freud noted1. Space is never universal, but subjective. A space would be a result of introjection or projection – which is to say, a product of the thinking and sensing subject as opposed to the universal and stable entity envisaged since the Enlighten. There is a spatial unconscious, susceptible to analysis and interpretation. Systematic Design: Digital media should bring about an autopoiesis. This approach calls into question traditional methods of architectural design – which replace the hierarchical processes of production known as “cause and effect” - and proposes a design process where the architect becomes a constructor of formal systems. Will the evolutionary simulation replace design? Is metric space dead? Is it replaced by the new definition of space, that of topology? The new algorithmic evolutionary conditions give architecture an autopoiesis, similar to biological dynamics. The use of algorithms in design and fabrication has shifted the role of the architect from design to programming. Parametric design has introduced another dimension: that of variation and topological evolution, breaking the authentic into the reused. Architecture now is about topology than typology, variation than authenticity, it is mimetic than original, uncanny and subconscious than merely generic. In a parallel universe, which is both algorithmic and metaphysical, the modeling machine creates a new abstraction, the morphogenesis of the “new hybrid condition”. The emphasis of the exploration is on morphological complexity. Architecture may become – paradoxically - rigorous yet more uncanny and introverted.

title	3D Print as Corporeal Design Medium
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 137-152
summary	Because it produces representational models, not full-scale architecture, 3D printing often supports the study of form, not architectural materials, structure and tectonics. This research asks how 3D printing can support material study and contribute to a process of design by making, similar to that achieved with mock-ups and other full-scale constructions. It clarifies the nature of design by making through an elaboration of key activities, and then shows how 3D printing can support each activity. The research includes a design experiment in which students used unique 3D printing techniques to enhance the experience of design by making. These techniques include 1) confronting a material foil, 2) embedding material placeholders in parametric models, 3) oscillating between representational and literal interpretations, and 4) using 3D prints as a corporeal medium. With these techniques, 3D printing offered a unique flavor of design by making, which can complement full-scale computer-aided manufacturing techniques.

title	Dry-In House: A Mass Customized Affordable House for New Orleans
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 359-362
summary	Dry-in house is a mass customized affordable housing system proposed for the reconstruction of New Orleans. The dry-in House gets the owner back to their home site quickly while providing the infrastructure an occupant needs (shelter, water, electricity). The owner is supplied with an inhabitable shell that is customizable before it is fabricated as well as onsite as the project is “fitted out” over time. The key concept is to allow families to participate in the design of their customized homes and to get people back to their home sites as quickly as possible and to give them the opportunity to finish and further customize their home over time. The project addresses inefficiencies and redundancies in emergency housing currently provided by FEMA. Primarily the dry-in House as its name implies provides a timely dried-in space which doubles as a customized infrastructure for the reconstruction of homes and neighborhoods. The project is designed to meet the $59,000 life cycle cost of the presently provided temporary housing, the notorious “FEMA Trailer”. However, the Dry-in House provides a solution that: a) Is permanent rather than temporary. The house will be finished and further customized over time rather than disposed of. b) Reoccupies the owner’s home site rather than a “FEMA ghetto” keeping the community together and functioning. c) Is mass customized rather than mass-standardized allowing the owner to have input on the design of their home. The design is a “starter home” rather than an inflexible and over-determined solution. This also has the benefit of giving variation to the reconstruction of New Orleans as opposed to the monotony of mass-production. d) Allows the owners to further customize their home over time with additional exterior finishes and the subdivision and fit out of the interior. By utilizing plate truss technology and associated parametric modeling software, highly customized trusses can be engineered and fabricated at no additional cost as compared to off-the-shelf trusses. This mass customization technology is employed to create the building section of each individual’s house. The truss is not used in its typical manner, spanning over the house; rather, it is extruded in section to form the house itself (roof, wall, and floor). Dry-in House exploits this building technology to quickly rebuild communities in a sensible manner. It allows for an increased speed of design and construction and most importantly it involves the owner in this process. The process has other benefits like reducing waste not only because it replaces the FEMA trailer which is expensive and disposable but also since the components are prefabricated there is more precision and also quality. The Dry-in House allows the owner-designer to “draw” the section of their new home providing them with a unique design and a sense of belonging and security. The design of the section of the house also provides them with spatial configurations customized relative to site conditions, program etc... Because of the narrow lot configuration of New Orleans, the design maximizes the roof as a source for natural ventilation and light for the interior of the house. In addition, the house is one room deep providing cross ventilation in all rooms minimizing reliance on artificial mechanical systems. The timely and efficient off site fabrication of building sections facilitate larger concentrations of volunteers on site at one time, thereby promoting a greater collective spirit among the community and volunteer workforce, a therapeutic event for the community as they participate in the rebuilding of their homes and city. With individualized building sections arriving on site, the construction process is imagined to be more akin to a barn raising, making possible the drying in of multiple houses in less than one day.

title	The Digital Ornament using CAAD/CAAM Technologies
source	International Journal of Architectural Computing vol. 4 - no. 1, 33-49
summary	New digital technologies are challenging the traditions of the architectural design methodology, the relationship between context and design, and the dependency on skilled workmanship for the fabrication of beautiful and complex architecture. Intellectually, applications of digital technologies are also allowing for the reinvestigation, reinterpretation, and redevelopment of historical concepts, theories, and skills[1]. Our focus of ornament in this paper is presented as a constrained architectural testing ground, a reduced issue that still addresses the primary issues of geometry, aesthetics, individualism, and the transferal of design to materiality. Our work on digital ornament combines the traditionally intuitive skills of geometric & graphic manipulations with easily edited input (variables and digital images), control through parametric programming, and automated output (CNC manufacturing). The combination of these processes allows for efficient diversity and uniqueness of design, while also compensating for the increasing cost and declining availability of skilled artisans for the physical fabrication. The presented projects in teaching, research, and professional activities demonstrate our ongoing experiments with new technologies of programmed surface modeling and computer numerically controlled manufacturing (CNC manufacturing). This work has been incorporated in real world projects, both in the revitalization historic buildings, and in new applications of ornament in contemporary architecture.

title	Interactive Parametric Design and the Role of Light in Byzantine Churches
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 798-803
doi	https://doi.org/10.52842/conf.ecaade.2006.798
summary	Byzantine church design depended heavily on natural light which was used for evocative purposes. The orientation of the main axis of the church, the form of the apse and the location and size of its windows are affected by the need for sunlight to shine at the altar on a desired time and for a certain duration. Until now the process of accurately taking account of all the above parameters has been rather difficult and tedious. This paper illustrates the use of digital tools both for the analysis of the geometry of existing apse designs and the parametric generation of new ones. A sophisticated computer program was used to calculate sun angles during the Byzantine period incorporating calendar changes. In addition, Bentley System’s Generative Components software was used to construct a parametric model that allows the user to define the geometric conditions and parameters of the apse. The software would then iterate through multiple solutions to satisfy the desired conditions as well as allow the user to change the conditions at will. The tools were used to discover the geometry of the apse of the Byzantine church of Hagia Sophia in Constantinople and to analyze the apse of the Post-Byzantine church of the Xeropotamou monastery on Mount Athos in Greece. The paper concludes with a discussion of the role of parametric tools for architectural analysis and the generation of possible design solutions.

title	Critical Environmentalism and the Practice of Re-Construction
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This research focuses on the implications and applications of “critical environmentalism” as a quintessential epistemological framework for urban interventions while implementing digital applications that foster collective, round-table approaches to design. Essentially centering the environment (Umwelt) as an encompassing and interconnecting catalyst between multiple disciplines, philosophies, and modes of inquiry and technologies, the framework reciprocally fosters individual and critical identities associated with particular places, belief systems, and their participants as a primary concern. Critical environmentalism promotes a comprehensive, reciprocally unifying epistemological framework that can significantly inform architectural interventions and the tethered use of its technologies in order to foster increased vitality and a certain coinvested attention to the complexities of the greater domain. Grounding the theory in pedagogical practice, this paper documents an approach to urban design and architectural education, implemented as a case-study and design scenario, where divergent perspectives amalgamate into emergent urban configurations, critically rooted in the conditional partialities of place. Digital technologies are incorporated along with analogical methods as tools to integrate multiple perspectives into a single, working plane. Engaging the above framework, the approach fosters a critical (re)construction and on-going, co-vested regeneration of community and the context of place while attempting to dialogically converge multiple urban conditions and modes-of-thought through the co-application of various digital technologies. Critically understanding complex urban situations involves dialogically analyzing, mapping, and modeling a discursive, categorical structure through a common goal and rationale that seeks dialectic synthesis between divergent constructions while forming mutual, catalyzing impetuses between varying facets. In essence, the integration of varying technologies in conjunction, connected to real world scenarios and a guiding epistemic framework cultivates effective cross-pollination of ideas and modes through communicative and participatory interaction. As such it also provides greater ease in crosschecking between a multitude of divergent modes playing upon urban design and community development. Since current digital technologies aid in data collection and the synthesis of information, varying factors can be more easily and collectively identified, analyzed, and then simultaneously used in subsequent design configurations. It inherently fosters the not fully realized potential to collectively overlay or montage complex patterns and thoughts seamlessly and to thus subsequently merge a multitude of corresponding design configurations simultaneously within an ongoing, usable database. As a result, the pedagogical process reveals richly textured sociocultural fabrics and thus produces distinct amplifications in complexity and attentive management of diverse issues, while also generating significant narratives and themes for fostering creative and integrative solutions. As a model for urban community and social development, critical environmentalism is further supported the integrative use of digital technologies as an effective means and management for essential, communicative interchange of knowledge and thus rapprochement between divergent modes-of-thought, promoting critical, productive interaction with others in the (co)constructive processes of our life-space.

title	Light and Form in Design – A Computational Approach
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 254-257
summary	Shape perception is strongly influenced by the reciprocal relation between light and form. Computational applications can increase the number of design alternatives taking into account possible variations in the relation between light and form. The aim of this study is to discuss a pedagogical experience carried out with 5th semester architectural students, based on a series of exercises prior to the term project. The exercises were concerned with the relation between light and form from an aesthetical point of view and should be understood as examples for the use of computers as tools to creatively accelerate the process of design and learning. The paper is divided in five parts. The first one describes the conceptual background for the exercises, a descriptive method for the identification of light effects in architectural objects based on ideas of shape emergence. The exercises’ methodology is explained in the second part, referring to the use of computational applications in 3-dimensional modeling, material and light simulation. The methodology includes different phases: –creation of bi-dimensional compositions according to symmetry operations; –creation of a minimal living space assigning functions to spaces originated from the former composition; –analysis of the impact of light on the form and spaces created; –alteration of form and materials creating new light effects considering the functions related to the spaces. The exercises alternate work in computational environment in two and three dimensions with the use of mockups, lamps and photography. In the third part the results –student’s design steps– are described. In the fourth part the results are analyzed and some conclusions are outlined in the fifth and last part. The use of emergent forms combined with computational tools has proved to be an effective way to achieve an accelerated understanding of the impact of light on forms as demonstrated by the evolution of the students work during the term and by their final results concerning the term project.

title	Pen or PC? - Is Sketching essential to architectural design?
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 810-817
doi	https://doi.org/10.52842/conf.ecaade.2006.810
summary	This paper reports on an ongoing student architectural design project that is investigating the differing effects of the use of PC’s or Pens in the design process. We are interested to see whether designing wholly on the computer with a volume modeling software would produce differing results to a traditional design process with a strong basis in 2D sketching. To minimize the influence of the participants previous experience in either the use of PC’s or the pen, we have been working with very young students that have not yet gone through a traditional training on architectural design and CAAD software. This is one of the key aspects of our experimental procedure. We have found that recent software developments in the field of CAAD clearly have and will influence the way architects design and brings the computer as a design tool to the “normal architect”. Until very recently the computer was seen as a design tool almost solely for “computer geeks” in the profession, the majority of architects still using it mainly as a drafting machine or to produce visualizations of their projects after a more ‘conventional’ design process had finished. It is now very clear to us that the ongoing change in technology will have a profound effect on the way all of us will work in future undertaking architectural design. It is an important question for every school of architecture what effect these developments will have on our teaching methods and the curricula. We use the above mentioned ongoing educational project to find out about the benefits and risks of using the computer as a design tool for first year students.

summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title	Hybrid modeling revaluing manual action for 3D modeling

summary	3D modeling software uses conventional interface devices like mouse, keyboard and display allowing the designer to model 3D shapes. Due to the complexity of 3D shape data structures, these programs work through a geometrical system and a graphical user interface to input and output data. However, these elements interfere with the conceptual stage of the design process because the software is always asking to be fed with accurate geometries—something hard to do at the beginning of the process. Furthermore, the interface does not recognize all the advantages and skills of the designer’s bare hands as a powerful modeling tool.This paper presents the evaluation of a hybrid modeling technique for conceptual design. The hybrid modeling approach proposes to use both computer and manual tools for 3D modeling at the beginning of the design process. Using 3D scanning and rapid prototyping techniques, the designer is able to go back and forth between digital and manual mode, thus taking advantage of each one. Starting from physical models, the design is then digitalized in order to be treated with special modeling software. Then, the rapid prototyping physical model becomes a matrix or physical 3D template used to explore design intentions with the hands, allowing the proposal of complex shapes, which is difficult to achieve by 3D modeling software alone.

summary	Simulation is a means to help urban planners and investors to optimize inhabitant satisfaction and return on investment. An example is the optimal match between household preferences and property profiles. The problem is that not enough knowledge exists yet about dynamic user activity models to build reliable and realistic simulators. Therefore, we propose a modeling and software technique that produces simulator prototypes very efficiently for the development, test, and evaluation of many different user activity models, using executable models, code generation, and a domain specific software process. As a specific feature, the model is based on many agents acting independently from each other and that are mapped in several refinement steps into the same number of concurrent processes. The housing example is used as a case study to explain the process and show performance results.

title	Developing a Spatial Context-Aware Building Model and System to Construct a Virtual Place

summary	The current notion of space seems to be inappropriate to deal with contemporary and future CAAD applications because it lacks of user and social values. Instead of using a general term called 'space', our approach is to consider the common unit in architectural design process as a place composed of space, user and activity information. Our research focuses on developing a novel intelligent building data model carrying the essence of place. Through our research, the needs of using virtual architectural models among various architectural applications are investigated at first step. Second, key characteristics of spatial information are summarized and systematically classified. The third step is to construct a semantically-rich building data model based on structured floor plan and the semantic location modeling. Then intermediate functions are created providing an interface between the model and future applications. Finally, a prototype system, PlaceMaker, is developed to demonstrate how to apply our building data model to construct virtual architectural models embodying the essences of place.

summary	Architectural competitions have been traditionally used to select best design practices. The basis of assessment for competitions has typically involved non-technical concepts of quality, subjective and emotional appreciations of experiences, and inseparable accord of formal, functional, aesthetic and contextual values (Rönn, 2011), rather than clear-cut objective and precisely measured values as in the engineering domain (Nashed, 2005; Nelson, 2006). Criteria for judgment usually focus on design parti and clarity of concept, novelty of architectural approach, context compliance, spatial organization, functional adaptability, economical solutions, and design flexibility. The assessment process, although presumably comprehensive and involving multiple evaluation techniques and resources, may still overlook important technical issues that may be fundamentally significant to the exclusion or approval of a given entry. This paper introduces a framework for assessing architectural competition entries aided by concepts of building information modeling (BIM).

title	Exploring Heuristics Underlying Pedestrian Shopping Decision Processes - An application of gene expression programming
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 121-136
summary	Most analytical pedestrian behavior researches use utility-maximizing models and have paid less attention to models based on alternative behavioral theories such as bounded rationality. Consequently, there is a lack of deeper explorations into the decision processes of pedestrians. This lack of such alternative models may also be the result of inappropriate methods to estimate such models. For this reason, the paper first introduces a modeling platform GEPAT which has the ability to estimate parallel functions using a multi-gene-sectional chromosome structure and to facilitate building models using processors emulating simple decision mechanisms. The going-home decision of pedestrians in Wang Fujing Street is taken as an example to illustrate the use of GEPAT. The most important conclusion from a comparison of the MNL, hard cut-off, soft cut-off and hybrid model is that the satisficing heuristic fits better to the problem structure, at least in this case, than the utility-maximizing rule does. This example also shows the flexibility of GEPAT as a modeling toolbox and the power of estimating complex models.
