summary The paper presents ongoing applied research on the development of a computational design tool addressing planning deficiencies in the city of Addis Ababa, Ethiopia. Because of increasing population pressure and a lack of planning resources, Addis Ababa is clearly in need of new efficient planning solutions. The tool proposed utilizes and combines different generative design methods in order to increase the efficiency of planning and construction processes. The paper discusses design goals and the implementation strategy involved.

title Bridging GIS-based landscape analysis/modelling and 3D-simulation.Is this already 4D?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

summary The dynamics of a physics-based algorithm which acquires its complex organization through a number of localised interactions applied over a prescribed network can be described as a self-organised system. This in turn has the capacity to define explicit form and space based upon behavioural computational processes with an embedded structural logic. This paper discusses the way in which physics based algorithms can be used to inform the organisation of a compressional structure in a case study. Its structure is based on Hooke’s law of elasticity; which establishes a three dimensional catenary logic through a number of localised interactions applied over an entire network. This is applied to a project with specific constraints to site, boundary conditions and maximising solar gain whilst maintaining structural rigidity. The methodological approach describes the design to assembly process in which the project has been developed. This includes the applied generative design tools in order to establish the self-organised logic, the form finding process, the techniques of design documentation, the fabrication process and the logistics of construction and assembly.

title Towards a modular design strategy for urban masterplanning - Experiences from a parametric urban design studio on emerging cities in Ethiopia
source Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 1, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 485-494
summary In emerging countries there is a need for rapid urban planning, since they are confronted by unprecedented wave of urbanization. This need is even bigger since usually there is no adequate number of professional educated urban planners in these countries. Therefore, we investigate in this paper how to develop a set of methods that allow to generate urban fabric semi-automatically. The challenge is to come up with a generative planning model that adapts to multiple boundary conditions.Through a modular design strategy generative methods are applied by students in an urban design studio in order to combine them into more complex planning strategies for small cities in the emerging country of Ethiopia. The modular approach allows to break down planning into sub-issues to better deal with the overarching problem. For testing the implemented generative urban design strategies various cities are generated at different locations in Ethiopia with various topographic situations. Their underlying design strategies and modular approach are discussed in this paper.

title Using Virtual Reality Aided Design Techniques for Three-dimensional Architectural Sketching
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 199-212
summary With this paper we would like to introduce a system which supports the early phases of the architectural design process. The system consists of two main components: the software solution "voxDesign" and the physical environment "platform". Our aims are: to formulate, develop, and evaluate an architectural design system through the use of VR (virtual reality) space. The exploration and development of design intentions is supplemented by a new method of three dimensional sketching. In the second part of this paper we will show how these components were used to train students in architecture and design at our university. Parts of this paper were published to the academic public at "Designing Digital Space". (Regenbrecht 1996)

title Integrated Computer-Assisted Building Surveying for Architectural Planning
source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 183-192
summary The paper describes a concept for the step-by-step computer-aided capture and representation of geometric building data in the context of planning-oriented building surveying. Selected aspects of the concept have been implemented and tested as prototypes. The process of step-by-step capture and representation is determined by the order in which the user experiences the building. Only the information that the user knows (can see) or can reasonably deduce is represented. In addition approaches to the flexible combination of different measuring techniques and geometric abstractions are described which are based upon geodetic computational adjustment. The paper also examines the flexible combination of different surveying techniques and geometric abstractions achieved with the help of geodesic computational adjustment methods. Selected aspects have been implemented and investigated as prototypes. All prototypes will be shown and discussed.

source eCAADe Conference Proceedings / 0-9523687-6-5 / Weimar (Germany) 22-24 June 2000, 334 p.
summary This years annual eCAADe conference in Weimar about the theme "promise and reality", wants to focus on the "effusive feelings" related to the use of computers, digital media and information technology in the field of architecture. It was strictly forced by the conference committee to discuss and highlight the actual situation in applied computer science in architectural design and planning. The reader will find both in the conference proceedings, the formal description of interesting research and teaching projects as well as the description of existing or expected conflicts in using computer technologies as an architect. Scientists from around the world contributed the results of their action research in the field of applied computer science for the building and urban design, planning and construction process. Architects, civil engineers, computer scientists, designers, philosophers and social scientists will illuminate and critically reflect their current work. Their contributions circumstantiate the present situation in Computer Aided Architectural Design. It might be said that we all share imaginations about the use of digital media in the future.

summary The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

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.

summary This paper examines the progressive and pragmatic use of computers and CAAD systems in the architectural practice. With the aid of three scenarios, this paper will illustrate gainful implementation of computer aided project planning in architecture. The first scenario describes an actual situation of implementation and describes conceptual abortive developments in office organization as well as in software technology. Scenario two outlines the essential features of an integrated building design system and the efforts involved in its implementation in the architectural practice. It clearly defines preconditions for implementation and focuses on feasible concepts for the integration of different database management systems. A glance at paradigms of conceptual work currently under development will be taken. The third scenario deals with the structure and integration of innovative concepts and the responsibility the architect will bear with regard to necessary alterations in office and workgroup organization. A future-oriented building design system will be described that distinguishes itself from existing programs because of its modular, net-based structure. With reference to today’s situation in architectural offices and according to realizable improvements, this article will demonstrate courses for future IT-support on the basis of an ongoing research project. The presented project is part of the special research area 524 “Materials and Constructions for the Revitalization of Existing Buildings” which is funded by the Deutsche Forschungsgemeinschaft. It deals with the integration of various parties that are involved in the revitalization process of existing buildings as well as with the provision of adequate information within the planning process resting upon the survey of existing building substance. Additional concepts that might change the way an architect’s work is organized will also be presented. “Case-based-reasoning” methods will make informal knowledge available, leading to a digital memory of preservable solutions.

summary This paper describes the development of a software concept and a prototype system for a structured way of collecting and organising information about existing buildings. An analysis of traditional methods and processes involved in architectural surveying forms the basis for the development of a programming system for the structured surveying, preparation, organisation and use of digital information about existing architectural objects. Use is made throughout of current tools and techniques in the field of applied informatics, and these in turn are evaluated as to their suitability and usefulness. Particular emphasis is given to the systematic breakdown of a building into its component parts and information relevant to its use and planning, and to the integration of different methods of capture and presentation of this information. The architects' normal working methods inform the entire process.

summary The aim of this project is to develop a software system for generating complex digital models of existing buildings and structures, i.e. in the broadest sense a computer-supported surveying and management system for existing buildings. The built environment is registered by surveying a series of geometrical and building relevant information broken down into different levels of abstraction. The recorded data consists of a variety of geometric, multimedia and verbal - less structured - pieces of information. The starting point for developing such a system is both an analysis and reworking of the methods used in architectural surveying, and the evaluation and use of current techniques and tools in the field of computer applications.

source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 333-341
summary The paper describes the concept and development of software to support the architectural design and planning of colour schemes for interiors and buildings. “Coloured Architecture” is a plausibility instrument for the formulation of colour scheme proposals for building interiors and elevations. In practice colours schemes are arrived at through the production of many different colour design studies before a final colour scheme is decided upon. With the help of intuitively usable light simulations, colour, material and spatial concepts can be assessed realistically. The development concept incorporates numerous aspects which must be considered in the selection of a colour scheme: colour schemes for built environments must be realisable . This initial development prototype already demonstrates the added value possible through the consequent use of CAAD: function, construction and not least design aspects have equal status and can be worked upon in direct relation with one another.

summary As a result of growing activity in the field of renovation and building within existing built contexts, modern digital tools and methods are increasingly in demand. Support of the planning process means: the step-by-step capture of building-relevant information, a rule and parameter-based development of solutions and the combination of traditional and automated methods and technologies used for model creation (building surveying) and model transformation (planning). This article discusses general requirements and the results from our own research and development as well as illustrating how building surveying can already contribute to the planning process more effectively using currently available tools.

summary Architecture is more than form. It must be more than form. It can be spectacular, it can be revolutionary,but it should also be comprehensible, reasoned and plausible and this should be reflected in its form.This very nature of architecture makes it different from other design disciplines. However, it is thesecentral aspects that are not supported by current computer-aided planning systems. The developmentof digital models concentrates on the purely formal aspects.

summary In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during four years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Two programs were developed at Bauhaus University with the aim of teaching students in architecture in three-dimensional sketching. An other program for free and own interfaces and environments is currently under construction and will be presented at the international computer fair "CeBit" in 1999. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. All programs force the users to design in a 1:1 scale, which means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by the students are explained too.
