title Scripting Design Supported by Feedback Loop from Structural Analysis
source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 1, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 51-59
summary In order to support an architect’s decision to evaluate and choose more efficient structural solutions in the concept design, it is necessary to establish an interactive feedback loop between structural solver and geometry modeller which would allow one to analyse a great number of solutions generated in the scripting design process. Defining a cross-disciplinary data structure as an analytical model, the communication between existing structural solver (OOFEM) and geometry modeller (Grasshopper) was established. Automation of the entire analysis process was done by the bridging tools MIDAS and Donkey, which have been developed. This paper presents the method of creation of an analytical model by Donkey, and deals with how to visualize, interpret and use the result values from the structural analysis.

source CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 133-141
summary Information is everywhere. We are flooded by information and one can observe peoples problems handling the amount of information. The relational table as the mean to present information as well as simple html pages are having their obvious depts. Therefore, people are looking into three-dimensional representations and entire virtual environments to visualize data contents. Within this papers it is proposed to visualize information and information structures in a dynamic fashion. Therefore, we will have a look at some principles of dynamic representations as well as the metaphors and methods used to enables dynamic representations. With Autonomous Objects in Sculptor and inforMotion two examples are implemented in our research projects using dynamic data visualization.

title The S. Pedro da Cova Community Knowledge Centre, a local example of empowerment through technology
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary S. Pedro da Cova (Gondomar), located ten kilometres from the city centre of Porto (Portugal), is considerate a depressed territory, with a large spectrum of social, economic and urban problems, but also with local positive aspects capable to reach the different development opportunities.In the ambit of the regeneration process for this area, the local authority draw a strategy based in the empowerment of the citizens, where the Information Communication Technologies (ICT’s) assumed a major role. With this purpose, it was intended to build a Community Technology Centre for the disfavoured children. From the building construction till the first activities, it is our conviction that to break the differences between the have and the have not’s it will be very important to conciliate the new technologies and the local characteristics. The children will be the active agents in the dissemination of the project through the development of the different activities, sensitising the families to adopt a healthy life and announce situations of risk, for example. To validate the project will be created an permanent observatory that propose a moment of reflection and auto-valuation about the evolution of the different activities, thechanges to do, and the identification of new problems and the redefinition of new methodologies. The aim of the article is not only to show the positive aspects, indeed significant, but also to bring into discussion some questions; in order to understand the possibility of defining an empowerment strategy based in the ICT’s. How to conciliate the individualperspectives of the future into a common objective? How to show to all community that information and knowledge are fundamentalto build a more liveable and equity neighbourhood? How to transfer the results to a larger strategy for the entire city? And, at theend, how to explain that people is the most important "infrastructure" to build a better future?

title The Design of Buildings which Have Complex Mechanical Infrastructure using Expert Systems
source ACADIA Workshop ‘85 [ACADIA Conference Proceedings] Tempe (Arizona / USA) 2-3 November 1985, pp. 52-68
summary This paper presents a project under development at the University of Karlsruhe in which the author took part for two years. The aim of this project which was supported by the German Research Association (Deutsche Forschungsgemeinschaft) is to find better methods for the design of buildings having complex mechanical systems like laboratories, office buildings, schools, hospitals. etc. The design of the mechanical infrastructure in such buildings is as important as the design of other architectural or construction parts. The fundamental idea of the project is to consider design problems of the mechanical system as part of the design of the architectural and structural concepts of the entire building. This is based on the belief that the use of an expert system containing computer programs for the solution of design problems can support the whole design procedure and that the design of buildings having complex mechanical infrastructure can be qualitatively better and more efficient than the design with traditional methods.

summary This paper describes experimental work carried out in a special architectural design studio. It runs methods that are different of the traditional teaching in the .normal. studios. The entire working time is separated in two characteristic periods: .Creative tasks. and .Design tasks.. The purpose is to clarify the design process assuming that generating ideas has quite different characteristics than leading them to the real world. Creative work means imagination whose limits are difficult to establish. In fact imagination hates imposed limits. Conversely the final task of design is to determine limits. These two opposed forces are conciliated in the design process. Ideas as well as physical objects need special means of representation. These are discussed in order to illustrate the trends underlying this particular design studio. (Architecture, design, teaching, digital representation)

title Dissolvable 3DP Formwork
source ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp. 188-197
summary Additive manufacturing technology frees the designer and manufacturer from the constraints for creating formwork for castable materials. However, the removal of formwork remains a challenging task for specific geometric features such as undercuts and hollow parts. The entire formwork needs to be reachable by humans or machines to be broken, which poses a great risk of damaging the final concrete surface or destroying intricate details. This paper focuses on the development of a sustainable FDM 3D printed formwork system, enabling the casting of components at an architectural scale, without creating material waste. It does so by combining a minimal 3D printed shell with additional geometrical formwork features. Furthermore it proposes the usage of an alternative formwork material, Poly Vinyl Alcohol (PVA). PVA is water dissolvable, non-toxic, and biodegradable. Introducing water dissolvable 3D printed formwork allows designers to exploit in full the advantages of additive manufacturing technologies and the formability of castable materials. Concrete can be cast to fabricate one of a kind, full-scale, structural components without compromising the complexity of form, while at the same time, reducing the amount of material waste drastically.

summary The paper analyzes the theoretical and methodological approach of contemporary urban design associated to digital processes. This new approach to urban studies is based on parametric design systems in which the focus of interest is not in the form itself, but the parameters that generate it. As an alternative to traditional design system, this methodology provides greater control of the entire process, since the parameters can be changed during all stages of the work. Thus, this paper presents some cases to understand the advantages and disadvantages of using this new way of designing on urban scale.

title Testing the Space of the Virtual

summary Various modes of electronically mediated communication, perception, and immersive bodily engagement, generally categorized as “virtual experiences,” have offered the designer of space a new array of spatial conditions to address. Each of these modes of virtual experience, from text-based discussion forums to immersive virtual reality environments, presents challenges to traditional assumptions about space and its inhabitation. These challenges require design theorization which extends beyond the notions of design within the electronic space (the textual description of the chat forum, the appearance of the computer generated imagery, etc.), and require a reconsideration of the entire electronic and physical apparatus of the mediating devices (the physical spaces which facilitate the interaction, the manner of their connection to the virtual spaces, etc.). In light of the lack of spatial theorization in this area, this paper presents both an experimental framework for understanding this complete space of the virtual and outlines a current research project addressing these theoretical challenges through the spatial implementation of a synthetic environment.

title Visual navigation of large environments using textured clusters
source Proceedings 1995 Symposium on Interactive 3D Graphics, pp. 95-102, June 1995
summary A visual navigation system is described which uses texture mapped primitives to represent clusters of objects to maintain high and approximately constant frame rates. In cases where there are more unoccluded primitives inside the view- ing frustum than can be drawn in real-time on the workstation, this system ensures that each visible object, or a cluster that includes it, is drawn in each frame. The system supports the we of traditional "level-of-detail" representations for individual objects, and supports the automatic genera- tion of a certain type of level-of-detail for objects and clusters of objects. The concept of choosing a representation from among those associated with an object that accounts for the direction from which the object is viewed is also supported. The level-of-detail concept is extended to the whole model and the entire scene is stored as a hierarchy of levels-of-detail that is traversed top-down to iind a good representation for a given viewpoint. This system does not assume that visibility information can be extracted from the model and is thus especially suited for outdoor environments.

title Mission Possible: Computer Aided Design for Everyone
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 65-73
summary A pragmatic model for the building of an electronic architectural design curriculum which will offer students and faculty the opportunity to fully integrate information age technologies into the educational experience is becoming increasingly desirable.

The majority of architectural programs teach technology topics through content specific courses which appear as an educational sequence within the curriculum. These technology topics have traditionally included structural design, environmental systems, and construction materials and methods. Likewise, that course model has been broadly applied to the teaching of computer aided design, which is identified as a technology topic. Computer technology has resulted in a proliferation of courses which similarly introduce the student to computer graphic and design systems through a traditional course structure.

Inevitably, competition for priority arises within the curriculum, introducing the potential risk that otherwise valuable courses and/or course content will be replaced by the "'newer" technology, and providing fertile ground for faculty and administrative resistance to computerization as traditional courses are pushed aside or seem threatened.

An alternative view is that computer technology is not a "topic", but rather the medium for creating a design (and studio) environment for informed decision making.... deciding what it is we should build. Such a viewpoint urges the development of a curricular structure, through which the impact of computer technology may be understood as that medium for design decision making, as the initial step in addressing the current and future needs of architectural education.

One example of such a program currently in place at the College of Architecture and Planning, Ball State University takes an approach which overlays, like a transparent tissue, the computer aided design content (or a computer emphasis) onto the primary curriculum.

With the exception of a general introductory course at the freshman level, computer instruction and content issues may be addressed effectively within existing studio courses. The level of operational and conceptual proficiency achieved by the student, within an electronic design studio, makes the electronic design environment selfsustaining and maintainable across the entire curriculum. The ability to broadly apply computer aided design to the educational experience can be independent of the availability of many specialized computer aided design faculty.

summary This paper introduces the concept, structure, components, and application results of "SEMPER", an active, multi-aspect computational tool for comprehensive simulation-based design assistance. Specifically, SEMPER seeks to meet the following requirements: a) a methodologically consistent (first- principles-based) performance modeling approach through the entire building design and engineering process; b) seamless and dynamic communication between the simulation models and an object- oriented space-based design environment using the structural homology of various domain representations; and c) "preference-based" performance-to-design mapping technology (bidirectional inference). SEMPER involves the integrated computational modeling of heat transfer, air flow, HVAC system performance, thermal comfort, daylighting and electrical lighting, acoustics, and life-cycle assessment.

summary This paper introduces a comprehensive computational implementation effort toward the incorporation of simulation-based performance evaluation in building design. Specifically, the computational design support system `SEMPER' will be described. SEMPER's main objectives are: (i) a methodologically consistent (first-principles-based) and flexible performance modeling approach through the entire building design and engineering process; (ii) provision of comprehensive, i.e., multi-domain building performance evaluation support; (iii) seamless and dynamic communication between the simulation model and the general building representation in an object-oriented space-based design environment; and (iv) active convergence support via a bi-directional inference mechanism that provides not only the conventional design-to-performance mapping option but also a `preference-based' performance-to-design mapping technology.

title Shapes, Numbers, Perception: Aspects and Dimensions of the Design-Performance Space
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary The design-performance space denotes a virtual space that can be constructed based on discretized design variables and performance indicators. For an n-dimensional design-performance space, n = d + p,whereby d = the number of discrete design variables, and p = the number of discrete performance indicators. Once constructed, this space can be visualized and used by the designer to explore the relationship between design variables and corresponding performance attributes. We present, for the building design domain, an approach to generation and exploration of the design-performance space. In this approach, an initial design is used to generate a set of alternative designs that collectively constitutethe design space. One way of doing this relies on the "scalarization" of design variables. The scalarization leads to the representation of a building as a point in a d-dimensional design space. Each coordinate ofsuch a space accommodates a salient (semantic or geometric) design variable. Subsequently, the entire corpus of design alternatives is subjected to performance modeling. Based on the modeling results, an ndimensionaldesign-performance space is constructed. We specifically address the potential for and limitations of describing building geometry in terms of a continuous scalar dimension of the design space. We introduce the concept of "Relative Compactness", which is derived by comparing the volume tosurface area ratio of a shape to that of a (compact) reference shape with the same volume. We present the results of an empirical study, which shows a significant correlation between the numeric values of relativecompactness and the subjective evaluation of the compactness of architectural shapes.

title A Preliminary to Development of Expert Systems for Total Design of Entire Buildings
source New York: John Wiley & Sons, 1992. pp. 215-237 : tables. includes bibliography
summary This paper has two primary objectives. The first is to represent the practicability of making the design of entire buildings a conscious, craftsman-like, activity conducted in the clear, without the mystery that tends, because of designers' usual 'black box' methods, to surround it. To this end, a design strategy and some tactics for resolving decisions at critical stages in the design process, which the authors have described elsewhere, are recapitulated to show how total design of buildings can be pursued in a generic manner. This done, the way is opened for the second objective: to make the large and important field of work that is building design amenable to computerization. The form that pursuit of this second objective is taking is being influenced greatly by growing interest in expert systems, which for everyday professional building design appears a more useful development than previous CAD emphases on drafting and graphics. Application of the authors' design methods to a series of expert systems for the total design of entire buildings is therefore indicated. For such a vast project--the formulation of bases for design assistance and expert systems that can be integrated and used as a generic method for the total design of entire buildings, so that the results are more certain and successful than the outcome of the generality of present-day building design--the most that can be attempted within the limits of a single paper is a set of examples of some of the stages in the process. Nevertheless, since the design method described begins at the 'large end' of the process, where the most consequential decisions are made, it is hoped that the major thrusts and the essential CAD activities will be evident. All design is substantially iterative, and provided that the major iterations are intelligible, there should be no need for this demonstration to labor over the lesser ones

title Daylight Simulation: Validation, Sky Models and Daylight Coefficients
source De Montfort University, Leicester, UK
summary The application of lighting simulation techniques for daylight illuminance modelling in architectural spaces is described in this thesis. The prediction tool used for all the work described here is the Radiance lighting simulation system. An overview of the features and capabilities of the Radiance system is presented. Daylight simulation using the Radiance system is described in some detail. The relation between physical quantities and the lighting simulation parameters is made clear in a series of progressively more complex examples. Effective use of the inter-reflection calculation is described. The illuminance calculation is validated under real sky conditions for a full-size office space. The simulation model used sky luminance patterns that were based directly on measurements. Internal illuminance predictions are compared with measurements for 754 skies that cover a wide range of naturally occurring conditions. The processing of the sky luminance measurements for the lighting simulation is described. The accuracy of the illuminance predictions is shown to be, in the main, comparable with the accuracy of the model input data. There were a number of predictions with low accuracy. Evidence is presented to show that these result from imprecision in the model specification - such as, uncertainty of the circumsolar luminance - rather than the prediction algorithms themselves. Procedures to visualise and reduce illuminance and lighting-related data are presented. The ability of sky models to reproduce measured sky luminance patterns for the purpose of predicting internal illuminance is investigated. Four sky models and two sky models blends are assessed. Predictions of internal illuminance using sky models/blends are compared against those using measured sky luminance patterns. The sky model blends and the Perez All-weather model are shown to perform comparably well. Illuminance predictions using measured skies however were invariably better than those using sky models/blends. Several formulations of the daylight coefficient approach for predicting time varying illuminances are presented. Radiance is used to predict the daylight coefficients from which internal illuminances are derived. The form and magnitude of the daylight coefficients are related to the scene geometry and the discretisation scheme. Internal illuminances are derived for four daylight coefficient formulations based on the measured luminance patterns for the 754 skies. For the best of the formulations, the accuracy of the daylight coefficient derived illuminances is shown to be comparable to that using the standard Radiance calculation method. The use of the daylight coefficient approach to both accurately and efficiently predict hourly internal daylight illuminance levels for an entire year is described. Daylight coefficients are invariant to building orientation for a fixed building configuration. This property of daylight coefficients is exploited to yield hourly internal illuminances for a full year as a function of building orientation. Visual data analysis techniques are used to display and process the massive number of derived illuminances.

summary Direct computer programming of architectural geometry and of CNC tool pathways can control the fabrication of form and the related treatment of material. When the entire form creation and tool path process is taken on as a design problem, there is potentially a closer link between formal design intentions and their physical realization. This paper describes several case studies that engage computer programming as a first stage in an iterative design process coupled with more explicit control over CNC tool paths. It indirectly critiques the design exploration of geometry where there is only user command control over a CAD system and where the specification of CNC pathways is also less explicit. Examples of different strategies are compared in the same educational context.

title An IFC based design check approach for the optimisation of material efficiency in the built environment
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 275–284
summary Compared to other industries, the built environment is still the largest and one of the least efficient consumers of resources. Existing measures and procedures for resource recovery and reuse are focused on the demolition phase, when the composition of materials and structures is mostly unknown and hard to be analysed. Therefore, these measures are somewhat inefficient for overall high-rate material recovery. The enhancement of the integrated semantic planning process by the introduction of the IFC unified data standard and BIM technology is a first-time opportunity to track, analyse, document and simulate all relevant players, parameters and processes with an impact on the resource and material efficiency through the entire life cycle of a building in the design phase of a building project. The presented work explores the potential of IFC to serve as a framework for achieving a higher material efficiency in the built environment. A proposed design check approach for the simulation and optimisation of material efficiency in a building over its life cycle is based on a system of key parameters and actions organised in logic trees. The parameters and actions are translated into IFC objects. Additionally required IFC objects and properties are identified and described.

summary This paper deals with the CUMINCAD-repository (Cumulative Index on CAD), which was set up in 1998 and has served the CAAD-community since then as an important source of archived domain related information. CUMINCAD contains over 5,000 entries in the form of publications in the field of Computer Aided Architectural Design. The number has been growing steadily over the years. To date only advanced search mechanisms have been provided to access these works. This may work out well for a just-in-time location of a reference, but is inadequate for just in case browsing through the history of CAAD. For such applications, a hierarchical browsing interface, like one in Yahoo or is envisioned. This paper describes how the keyword categories were defined and how a moderate, distributed effort in defining the categories will allow machine-identified classification of the entire data set. The aim of the paper is to contribute to building up a wide spread consensus on what the appropriate keyword categories in CAAD are, and what sub-topics should sit below the main keyword categories.

title Integrated Energy Modeling for Computational Building Design Assistance
source Carnegie Mellon University, Department of Architecture
summary Insights into the importance of energy modeling in building design have not yet resulted in the sufficient and systematic use of modeling tools in practice. In recent years, there has been considerable discussion on the limitations of simulation tools, and there is a noteworthy consensus as to the nature of the contributing factors (material and time implications, problematic user-interfaces, inefficient data communication structures, poor integration with CAD systems, absence of 'active' design support). This thesis deals with three research questions that are especially pertinent to the quest for active, multi-aspect design and simulation environments: (1) The appropriateness and feasibility of a methodologically consistent performance modeling approach through the entire design process. (2) Strategies for a structurally 'seamless' containment of performance simulation within a computational design environment. (3) Technologies to facilitate dynamic and interactive performance-to-design mapping. At a paradigmatic level, this thesis critically examines the existing responses to each of these questions, and proposes alternative computational frameworks and technologies to overcome some of the system-immanent ('endogenous') limitations of the existing approaches. At an operational level, this thesis demonstrates the proposed solutions by implementing an active thermal simulation module (NOD

title A Distributed 3D Graphics Library
source SIGGRAPH 98 Conference Proceedings, Computer Graphics Proceedings, Annual Conference Series, 1998, ACM SIGGRAPH
summary We present Repo-3D, a general-purpose, object-oriented library for developing distributed, interactive 3D graphics applications across a range of heterogeneous workstations. Repo-3D is designed to make it easy for programmers to rapidly build prototypes using a familiar multi-threaded, object-oriented programming paradigm. All data sharing of both graphical and non-graphical data is done via general-purpose remote and replicated objects, presenting the illusion of a single distributed shared memory. Graphical objects are directly distributed, circumventing the "duplicate database" problem and allowing programmers to focus on the application details. Repo-3D is embedded in Repo, an interpreted, lexically-scoped, distributed programming language, allowing entire applications to be rapidly prototyped. We discuss Repo-3D's design, and introduce the notion of local variations to the graphical objects, which allow local changes to be applied to shared graphical structures. Local variations are needed to support transient local changes, such as highlighting, and responsive local editing operations. Finally, we discuss how our approach could be applied using other programming languages, such as Java.
