title	Solving Revitalization-Problems by the Use of a Constraint Programming Language
source	IKM 2006, International Conference on the Applications of Computer Science and Mathematics in Architecture and Civil Engineering, Weimar, July 2006
summary	This research focuses on an approach to describe principles in architectural layout planning within the domain of revitalization. With the aid of mathematical rules, which are executed by a computer, solutions to design problems are generated. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a problem, an exemplary method will be described to solve such problems in architectural layout planning. To avoid conflicts relating to theoretical subtleness, a customary approach adopted from Operations Research has been chosen in this work [1]. In this approach, design is a synonym for planning, which could be described as a systematic and methodical course of action for the analysis and solution of current or future problems. The planning task is defined as an analysis of a problem with the aim to prepare optimal decisions by the use of mathematical methods. The decision problem of a planning task is represented by an optimization model and the application of an efficient algorithm in order to aid finding one or more solutions to the problem. The basic principle underlying the approach presented herein is the understanding of design in terms of searching for solutions that fulfill specific criteria. This search is executed by the use of a constraint programming language.

title	Designing with Machines: solving architectural layout planning problems by the use of a constraint programming language and scheduling algorithms
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	In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe principles in architectural layout planning in the form of mathematical rules that will be executed by the use of a computer. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, an exemplary method will be described to solve problems in architectural layout planning. Two problem domains will be examined: the design of new buildings, as well as the revitalization of existing buildings. Mathematical and syntactical difficulties that arise from the attempt to extract rules that relate to the process of building design will be pointed out. To avoid conflicts relating to theoretical subtleness a customary approach has been chosen in this work which is adopted from Operations Research. In this approach design is a synonym for planning, which could be described as a systematic and methodical course of action for the analysis and solution of current or future problems. The planning task is defined as an analysis of a problem with the aim to prepare optimal decisions by the use of mathematical methods. The decision problem of a planning task is represented by an optimization model and the application of an efficient algorithm to aid finding one or more solutions to the problem. The basic principle underlying the approach presented herein is the understanding of design in terms of searching for solutions that fulfill specific criteria. This search will be executed by the use of a constraint programming language, which refers to mathematical as well as to integer and mixed integer programming. Examples of architectural layout problems will be presented that can be solved by the use of this programming paradigm. In addition to this, a second programming approach resulting from the domain of resource-allocation has been followed in this research. It will be demonstrated that it is as well possible, to aid architectural layout planning by the use of scheduling algorithms.

title	MultiCAD – MOGA A System for Conceptual Style Design of Buildings
source	Conference Proceedings of the 9th 3IA (2006) International Conference on Computer Graphics and Artificial Intelligence, p73-84
summary	The synthesis of the three-dimensional morphology of a building is one of the most important tasks in architecture. Space planning and morphology are of the most interesting and complex of architectural design problems. Architectural design is guided by the constraints on the spatial composition and the morphology of the final building. During the conceptual phase problems are characterised by fuzziness and complexity. Building requirements are ill-defined and contradictory. The designer should explore the solution space for alternative building solutions while refining requirements and style preferences. In this paper we present the development and implementation of an Evolutionary Declarative Design system prototype for the aid of conceptual style design of buildings. The system is a specific MultiCAD prototype system including architectural knowledge, architectural style and a multi-objective genetic algorithm. Two design cases are presented for two different architectural styles. The applicability and efficiency of the system prototype are discussed.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
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	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title	V I PA: A virtual campus for virtual space design
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 464-469
doi	https://doi.org/10.52842/conf.ecaade.2006.464
summary	The conceptual design of virtual spaces is creating new places in which to live and work. In consequence, new opportunities for work and employment are opening up for architects as well as for architectural educators. In response to this challenge, VIPA, a transnational virtual campus is currently being developed; it contains an e-learning and research platform for European architectural schools with a focus on virtual space design. The virtual campus integrates administrative, curricular, and communicative infrastructures, interactive, multimedia 3-D contents, and pedagogical considerations in respect of the aims, content and technologies employed. Virtual campuses are already established at most universities in the European Community, yet surprisingly e-learning is not yet widespread in architectural schools in Europe. E-learning is arguably still in an initial research phase; although there are best practice examples where e-learning is already replacing traditional study forms in other teaching disciplines. However, it has been found that although all the universities involved in the VIPA project have been involved in e-learning projects for many years, there is a considerable resistance to e-learning as being equally effective as traditional face-to-face studio teaching. Given the new virtual conditions of space design however, new contexts for learning are increasingly relevant. University curricula have developed out of local competencies, networks of teachers and researchers. These local factors need to be woven into the fabric of a transnational VIPA curriculum and supported with organizational layout, platform, user interfaces and their features. Participants will offer existing courses in virtual space design, as well as developing new ones. This offers the option for both present and future participants to adjust the VIPA courseware to suit local curricula demands, while offering a large range of courses and knowledge. An additional feature of VIPA is thus as a platform for curricula development in virtual space design. The paper reports on the VIPA project’s aims, pedagogical problems, solutions, course content and methods; it will describe prototype results from participating universities and include perspectives on its future application.

title	STRONG VALID INEQUALITY CONSTRAINTS FOR ARCHITECTURAL LAYOUT DESIGN OPTIMIZATION
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 179-185
doi	https://doi.org/10.52842/conf.caadria.2006.x.w5d
summary	In the past decades, many attempts have been made to solve the challenging architectural layout design problem such as non-linear programming and evolutionary algorithm (Michalek and Papalambros, 2002). The Mixed Integer Programming (MIP) (Kamol and Krung, 2005) was recently developed to find the global optimal solution. However, the problem can be shown to belong to the class of NP-hard problem (Michalek and Papalambros, 2002). Hence, only the small instances of the problem can be solved in a reasonable time. In order to deal with large problem sizes, this paper utilizes the strong valid inequalities (George and Laurence). It cut off the infeasible points in the integral search space by formulated the disconnected constraints involved with line configurations of three rooms. It is shown to significantly increase the computational speed to more than thirty percents. This exhibits the practical use of the MIP formulation to solve the medium size architectural layout design problems.

title	Revitalization of Existing Buildings through Sustainable Non-Destructive Floor Space Relocation
source	GBEN 2006, Global Built Environment Network: Towards an Integrated Approach for Sustainability, P. 181-189
summary	The revitalisation of existing buildings is getting more and more important. We are facing a situation where in many cases there is no need to design new buildings because an increasing number of existing buildings is not used anymore. The most ecological procedure to revitalise these buildings would be through a continuous usage and by making few or no alterations to the stock. Thus, the modus operandi could be named a “non-destructive” approach. From the architects’ point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilisation of specific rooms to converge in a design solution. With the aid of mathematical rules, which will be executed by the use of a computer, solutions to floor space relocation problems will be generated. Provided that “design” is in principle a combinatorial problem, i.e., a constraint-based search for an overall optimal solution of a problem, an exemplary method will be described to solve such problems.

summary	The revitalization of existing buildings is gaining importance. We are facing a development where, in many cases, there is no need to design new buildings because an increasing number of existing buildings are not used anymore. The most ecological procedure to revitalize these buildings would be through a continued usage and by making few or no alterations to the stock. Thus, the modus operandi could be called a “non-destructive” approach.From the architect’s point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms in order to reach a design solution. With the aid of mathematical rules, which will be executed by the use of a computer, solutions to floor space relocation problems will be generated. Provided that “design” is in principle a combinatorial problem, i.e., a constraint-based search for an overall optimal solution of a problem, an exemplary method will be described to solve such problems.The design of the model developed is related to problems in logistics (e.g., the loading in trans-shipment centers). The model does not alter geometric proportions or locations of rooms, but solely changes their occupancy such that a new usage could be applied to the building. From our point of view, non-destructive models can play an important role in floor space relocation processes. Our examinations demonstrate that new patterns of utilization could be found through the use of this model.

summary	This article explores the correlation between the language of cinema and the architectural spatial discourse of power depicted in the film Equilibrium (Wimmer, 2002). This connection is examined through a discursive approach to communication studies. To analyze a specific sequence from the chosen film, a two-stage multimodal analysis was conducted. Initially, the visual analysis method proposed by Kress and Van Leeuwen (2006) designed for the representation of social actors, was employed. Subsequently, in the second stage, sociological and conceptual associations were drawn from the diverse semiotic resources identified in the first phase. The analyzed case revealed several intertextual relationships, among them; Hitler's figure recontextualized as an exemplifying archetype; the panopticon concept representing the spatial power dynamics; the presence of the German zeppelin symbolizing dominance and spreading propaganda through loudspeakers; the religious iconographic influence, its forms and symbols, contributing to a cultural identity inseparable from the history of the Western world.

source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 341-345
summary	This article is about the experience in the use of digital threedimensional models as an auxiliary tool in the phase of diagnosis on an architecture project of restoration. At first it deals with the importance and the methodology usually used in development of those projects. After telling about an experience that urged to look for new solutions, it was made a first exercise searching a new tool. It had about positive points the fact of being modeled quickly, to have made possible a clear vision of the pathologies and for being easily manipulable, providing a dynamic visualization of the construction. Another experience looked for the possibilities of analysis and quantification of damages in a photorealistic model. Afterwards analyzing the different potentials and restrictions of each accomplished experiment, this work looks for point out news ways that can be followed.

summary	Subject of study is the possible organisation of the Olympic Games of 2028 in the Netherlands, as seen from an urban development viewpoint. The project focuses on the decision-making process in the initiative phase. Aim of the project is the development of a decision support tool for the complex, interdisciplinary decision-making process which should result in an optimum interorganisational design. The methodology used to find the optimum choice is the combination of sub-solutions. Preference Measurement modelling based on a multi-criteria decision analysis is the technique employed. The group decision is a choice out of a number of Olympic urban development combinations, which is made in such a way that the preferred combination is the 'best' among the possible candidates for all relevant stakeholders.

title	A Framework For Generating And Evolving Building Designs
source	International Journal of Architectural Computing vol. 3 - no. 4, 449-470
summary	This paper describes a comprehensive framework for generative evolutionary design. The key problem that is identified is generating alternative designs with an appropriate level of variability. Within the proposed framework, the design process is split into two phases: in the first phase, the design team develops and encodes the essential and identifiable character of the designs to be generated and evolved; in the second phase, the design team uses an evolutionary system to generate and evolve designs that embody this character. This approach allows design variability to be carefully controlled. In order to verify the feasibility of the proposed framework, a generative process capable of generating controlled variability is implemented and demonstrated.

summary	The success of the international Zollhof project in Düsseldorf, Germany, in which virtual communication played a crucial role, was the catalyst for introducing interdisciplinary digital methods in the field of teaching. The firm of Frank O. Gehry and Associates, Santa Monica, California, served as an initial field of experimentation in order to bring together a heterogeneous group of project partners to participate in the design and construction phases of the Zollhof project. The design development, construction document, and construction phase was considerably enhanced by the employment of digital media as a communication and information tool. Parallel to the design process in the office in Santa Monica, a line of information flow and management had to be established to connect the local design team with consultants that were located in Europe and specifically in Germany. This line of communication required the team to send precise descriptions of project steps to the participants abroad, as well as receiving and processing a flow of responses returning to the Santa Monica office in very short intervals. By advancing and documenting each design and development step, the project progression was clearly documented by the project teams and thus understandable to everybody involved. The process demanded a highly articulated project description in text and images that were refined and exchanged daily. This helped to strengthen the cooperation between the design team and the project consultants and started to dissolve the role of the prime architect or designer toward a more team-related and democratic structure. All participants had quick access to all necessary information, which set aside the vertical hierarchy in favor of transparent communication tools and platforms.

summary	The “Case Studies in Architecture” phase of a course in architectural design includes in-depth comparisons and analyses of architectural precedents. However, with the large number of cases now readily available, Web searching and navigation is a time-consuming, low precision activity. In the work described in this paper, we built eCAADe, an educational commendation system for the adaptive semantic Web to allow students to query and retrieve semantically for architectural cases during the case study phase of an architectural design process. In our suggested system, we built a Semantic Web for design knowledge representation to make query and retrieval efficient. We also applied a hybrid recommendation mechanism, which is combining both content-based filtering and collaborative filtering to help for students to find relevant cases more efficient and precise with their preferences. We illustrate our concepts with several concrete examples.

summary	In a multi-player urban planning process, the outcome of any individual decision of the actors is uncertain until a state where the plan is satisfactory for all. To support the plan generation phase, this paper develops a generic multi-agent system, in which agents represent particular land-uses. In the system, agents higher in the hierarchy have priority over agents lower in the hierarchy to claim units of land. This one-direction claim process may result in a plan that is not optimal for every agent. The system, therefore, allows agents to revise their plans in an iterative procedure. A case study illustrates centralized, semi-centralized and decentralized solutions for a plan area based on the outcomes of different strategies used by facility agents (retail, green, schools) and a housing agent. The results show that the proposed system is able to generate rational and realistic plan alternatives for new residential areas.

title	VIRTUAL ENVIRONMENTS FOR THE EVALUATION OF HUMAN PERFORMANCE: Towards Virtual Occupancy Evaluation in Designed Environments (VOE)

summary	Analyzing and evaluating designs for modifications to suit the requirements of human performance is typically performed only after the architectural spaces and structures have been built and used, a process that is known as retrofit or post-occupancy evaluation. For people with disabilities, there is a special need to overcome this problem by evaluating the suitability of their home environments before the construction phase. Our work introduces a new methodology in which virtual reality (VR) is used for virtual pre-occupancy environmental evaluation (VOE). Our study demonstrates the potential of the VOE concept by developing an interactive living environments model to evaluate human performance before the construction phase. This paper presents an interactive virtual environment, ‘HabiTest’, as well as the initial results of a usability evaluation of this interactive environment.

title	Computational Assessment of Passive Cooling Methods in Buildings
source	Vienna University of Technology; Building Science & Technology
summary	Various factors have been contributing to a recent steady increase in buildings’ demands for cooling energy: environmental changes, increased heat gains due to equipment and growing expectations in view of acceptable indoor thermal conditions. Given this context, it’s both environmentally and economically meaningful to develop and implement passive cooling techniques toward the reduction of buildings’ demand for cooling energy. In the present study, we use parametric simulations to compute the relative impact of various passive cooling technologies toward the reduction of overheating risk in residential buildings. The cooling measures under examination are shading, natural ventilation (emphasizing on night time natural ventilation), and the application of phase change materials (PCM). The buildings that are being used for the parametric studies are an apartment and a double-storey single house, both simulated for a Mediterranean climate (Athens, Greece) and middle-European one (Vienna, Austria). The results showed that passive cooling methods can significantly contribute the reduction of overheating in buildings. In particular shading and night time ventilation have been shown to be very effective especially if applied in combination. PCMs on the other hand, showed a limited potential in the reduction of overheating risk, at least under the specific climatic circumstances.
