summary	This paper explores the idea that 3D city models integrated with hypermedia systems can facilitate the sense of belonging to a place. 3D models are powerful tools for buildings and urban space analysis as artifacts, which synthesize men’s reality and aspirations. As such, combined with hypermedia resources, they can strengthen the spectator’s actual experience in the analyzed space. The focus of the investigation is 3D models constructed to represent and analyze city evolution. The experience of developing the models of Latin American cities – Rio de Janeiro, Brazil and Havana, Cuba – developed at PROURB (Faculty of Architecture and Urbanism, Federal University of Rio de Janeiro) is explained with an overview of its methodology.

title	Analysis and the descriptive approach
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The rise of consciousness concerning the quality of working and living conditions has been a permanent though frequently underplayed theme in architecture and building since the reconstruction period. It has led to an explosive growth of programmatic requirements on building behaviour and performance, thus also stimulating the development of design analysis. The first stage of development was characterized by the evolution of prescriptive systems. These reversed the structure of pre-existing proscriptive systems into sequences of known steps that should be taken in order to achieve adequate results. Prescriptive systems complemented rather than replaced proscriptive ones, thereby creating an uncertain mixture of orthodoxy and orthopraxy that failed to provide design guidance for improving design performance and quality.The second stage in the development of design analysis focuses on descriptive methods and techniques for analyzing and supporting evaluation. Technologies such as simulation and scientific visualization are employed so as to produce detailed, accurate and reliable projections of building behaviour and performance. These projections can be correlated into a comprehensive and coherent description of a building using representations of form as information carriers. In these representations feedback and interaction assume a visual character that fits both design attitudes and lay perception of the built environment, but on the basis of a quantitative background that justifies, verifies and refines design actions. Descriptive analysis is currently the most promising direction for confronting and resolving design complexity. It provides the designer with useful insights into the causes and effects of various design problems but frequently comes short of providing clear design guidance for two main reasons: (1) it adds substantial amounts of information to the already unmanageable loads the designer must handle, and (2) it may provide incoherent cues for the further development of a design. Consequently the descriptive approach to analysis is always in danger of been supplanted by abstract decision making.One way of providing the desired design guidance is to complement the connection of descriptive analyses to representations of form (and from there to synthesis) with two interface components. The first is a memory component, implemented as case-bases of precedent designs. These designs encapsulate integrated design information that can be matched to the design in hand in terms of form, function and performance. Comparison between precedents with a known performance and a new design facilitate identification of design aspects that need be improved, as well as of wider formal and functional consequences. The second component is an adaptive generative system capable of guiding exploration of these aspects, both in the precedents and the new design. The aim of this system is to provide feedback from analysis to synthesis. By exploring the scope of the analysis and the applicability of the conclusions to more designs, the designer generates a coherent and consistent collection of partial solutions that explore a relevant solution space. Development of the first component, the design case-bases, is no trivial task. Transformability in the representation of cases and flexible classification in a database are critical to the identification and treatment of a design aspect. Nevertheless, the state of the art in case-based reasoning and the extensive corpus of analysed designs provide the essential building blocks. The second component, the adaptive generative system, poses more questions. Existing generative techniques do not possess the necessary richness or multidimensionality. Moreover, it is imperative that the designer plays a more active role in the control of the process than merely tweaking local variables. At the same time, the system should prevent that redesigning degenerates into a blind trial-and-error enumeration of possibilities. Guided empirical design research arguably provides the means for the evolutionary development of the second component.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	CAD Study in Visual Analysis of the Visual Sustainability for China Urban Natural Landscape Planning
source	Chinese University of Hong Kong
summary	In this thesis a GIS-based CAD system prototype of evaluating visual quality of urban natural landscape environment is presented. This prototype is an indispensable component of the integrative Visual Sustainability research, and offers a calculable and visualizable technique to urban visual natural landscape assessment. This scientific method provides precise data to estimate the visibility of natural landscape in urban construction actuality. Furthermore, it can also work out supporting information for maintaining and protecting valuable visual landscape resources in further planning. Introduction of this methodology intends to improve the natural landscape cooperation in China urban planning through visual protection. Combining with popular CAD software such as AutoCAD and Microstation, the research team uses ArcView GIS software and its 3D Analyst extension to accomplish a set of research procedure, which includes data modification, model making, viewshed and view sensibility analysis. In addition, this system can create simultaneous 3D scenes or hire other information media as reference tools for professional analysis, design consultation and intercommunication. The core technologies of this proposed system are viewshed calculation and overlay analysis. In viewshed analysis, human visual characteristics are simulated by a series of ergonomics parameters of viewpoints. Viewshed of each viewpoint can be calculated into vector data and mapped by polygons identifying which region is visible and which is not. Overlay function of the proposed system is used in visual sensibility analysis to achieve the division of higher visual sensible area which indicates the common visible area from different viewpoints. Additionally, viewshed maps and visual sensibility results can add more information to mark out the areas that can satisfy certain visual parameters such as appropriate visual angle or visual distance. These overlaying results can visualized the visible areas into hierarchical visual perception quality categories in order to define the visual landscape significance of particular planning regions. A case study was operated to evaluate this system. The case is in Zhongshan city, Guangdong Province of China. Jinzishan hill region is the study site that picked by collaborating discussion of research team and the local government. It is located on the edge of urban built-up area. Jinzishan massif is the prominent landscape element of the surrounding environment. There are three topics in Jinzishan visual perception in this paper. The first topic is the visual quality evaluation of the intersections of its surrounding road system. The second is the integrated visual perception of two main roads called Qiwandao and Bo‚Äôailu. Finally is the analysis of the hill skyline visual quality in surrounding area. The analysis results in GIS vector data can be converted into popular data format and combined with other spatial information for practical application. And comments for future urban planning are collected and analyzed by professional responses to the computer-generated information investigation.

title	Simulation and representation. Learning from airflow analyses in buildings
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 657-666
summary	The simulation of environmental aspects is a current priority in design research and practice. The availability of relatively efficient and reliable simulation systems and the emphasis on environmental aspects throughout a building’s lifecycle combine to stimulate exploration of aspects such as lighting and air quality by computational means. Nevertheless, a frequent complaint is that the addition of such simulations makes design information processing timeconsuming and cumbersome, thereby increasing uncertainty and indecision. Therefore, it is imperative that simulation is integrated in the strategies and tools normally used by the digitally-minded architect. In this respect a central issue is the relations between the simulation and the design representation used as connecting tissue for the whole design environment. Input of design information in the simulation means identification of relevant objects, aspects, parts and properties of these objects, as well as relationships between objects. The explicit description of objects such as spaces, doors and windows in the design representation allows for ready extraction of relevant information, including automatic recognition of relationships such as adjacency between a window and a space. The addition of information specific to the airflow analysis was resolved by the extension of the representation to cover front-end service components such as inlets and outlets and general properties (annotations) such as activities accommodated in a space and the primary choice of cooling and heating subsystems. The design representation is also the obvious target for the output of the simulation (feedback). Visualization of airflow in terms of the resulting voxels makes effortless and enjoyable viewing but merely allowing the visualization to coexist with the representation of spaces and building elements does not provide design guidance. One way of achieving that is by treating spaces not as integral entities but as containers of relevant surfaces. These surfaces determine the adaptive subdivision of the space and function as attractors for voxel clustering.

title	Mass-Customization in the Design of 4,000 Bus Stops
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

summary	Building projects are communicated through project documents. A collection of these documents are stored, related, and managed within digital environments for various purposes. These environments are all concerned with the complexity of organizing an information space: how to organize the information and to relate the individual entities within this organization in order to support effective searching and browsing of the resulting information structure. We present a methodology to handle this complexity through integrating a number of design documents of different formats within a single information structure. When this integrated structure is highly intra-related, it provides support for effective searching and browsing of this information. To achieve such intra-relatedness, we consider a notion of types from architecture as a semantic structure for project document management in the AEC industry. We discuss specific techniques to support this use of types with respect to EDMS’s and Web-based project management systems. We describe a prototype application, a presentation tool for architectural analyses, which combines these techniques.

title	Can simulations in VE support architects in solving complex design problems?

summary	Building design is facing development of industrialization of the production on the one hand and more complex 'One of a Kind' products on the other. This will be for rebuilding of a large stock of existing buildings and what can be left to new production. In both cases the results of the design process have to be solid to guarantee a successful product. In both cases an integrated and careful design process is absolutely crucial. The demands on the built environment make the systems of buildings more and more complex and have to be handled by a lot of different expertise. To avoid the 'Relay Race' of today the design teams of tomorrow must work much more integrated. To make integrated solutions, which means simultaneous constrains on all systems, the experts of different fields have to understand more of how all engaged systems relate and influence each other. Communication then consists of complex situations and processes that have to be understood and related to reality. In this aspect a multidimensional Virtual Environment interface has advantages and has been successfully used in design processes in other industries. In this paper the problems that have to be studied are for example Methodical, Conceptual, Technical and Process economical.

title	Facilitating the complexity of architectural analyses

summary	It is common practice for architecture students to collect documents on prominent buildings relevant to their design task in the early stage of design. While practitioners can rely on a body of design experience of their own, during the process of a new design, students can only draw from the examples of success and failure from other architects. In the past, such precedent based learning was implicit in the master-apprentice relationship common in the educational system. Nowadays academics commonly no longer have the possibility to maintain an extensive design practice, and instead introduce important outside precedents to the students. Thus, the study of important historical precedents or designs plays an important role in design instruction and in the students’ design processes. While there is no doubt that the most effective outcome of such a study would be achieved when the student does entire the study herself, students also benefit from a collaboration with peers, where they form groups to do an analysis of various aspects of a same building or over a group of buildings. By integrating the respective results into a common, extensible, library, students can draw upon other results for comparisons and relationships between different aspects or buildings. The complexity this introduces is best supported in a computer medium.The Web offers many examples of architectural analyses on a wide variety of subjects. Commonly, these analyses consist of a collection of documents, categorized and hyperlinked to support navigation through the information space. More sophisticated examples rely on a database for storage and management of the data, and offer a more complex categorization of the information entities and their relationships. These studies present effective ways of accessing and browsing information, however, it is precluded within these analyses to distinguish and relate different components within the project documents. If enabled, instead, this would offer a richer information structure presenting new ways of accessing, viewing, and interpreting this information. Hereto, documents can be decomposed by content. This implies both expanding the document structure, replacing document entities by detailed substructures, and augmenting the structure’s relatedness with content information. The relationships between the resulting components make the documents inherently related by content.We propose a methodology to integrate project documents into a single model, and present an application for the presentation of architectural analyses in an educational setting. This approach provides the students with a simple interface and mechanisms for the presentation of an analysis of design precedents, and possibly their own designs. Since all the information is integrated within a single environment, students will benefit from each others’ studies, and can draw new conclusions across analyses and presentations from their peers.

title	Interactive Walkthrough Environments for Simulation
source	University of California at Berkeley
summary	This thesis describes a second-generation walkthrough framework that provides extensive facilities for integrating many types of third-party simulation codes into a large-scale virtual environment model, and puts it in perspective with first-generation systems built during the last two decades. The framework provides an advanced model database that supports multiple simultaneous users with full consistency semantics, system independent storage and retrieval, and efficient prefetching and object reconstruction techniques to support second and third-generation walkthrough systems. Furthermore, our framework integrates support for scalable, distributed, interactive models with plug-in physical simulation to provide a large and rich environment suitable for architectural evaluation and training applications. A number of third-party simulations have been integrated into the framework, including dynamic physical interactions, fire simulation, multiple distributed users, radiosity, and online tapestry generation. All of these simulators interact with each other and with the user via a data distribution network that provides efficient, optimized use of bandwidth to transport simulation results to clients as they need them for visualization. These diverse simulators provide proof of concept for the generality of the framework, and show how quickly third-party simulations can be integrated into our system. The result is a highly interactive distributed architectural model with applications in research, training, and real-time data visualization. Finally, an outlook is given to a possible third generation of virtual environment architectures that are capable of integrating different heterogeneous walkthrough models.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	Object-Oriented Application Development in CAD
source	Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary	This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

(ed), Advances in Building Informatics, Proceedings of the 8th EuropIA International Conference on the application of Artificial Intelligence, Robotics and Image Processing to Architecture, Building Engineering & Civil Engineering, Delft, The Netherlands, April 25-27, 2001, pp. 113-125
summary	This paper focuses on three different aspects in which the IDEA+ core model differs from many other product modelling research initiatives: the systematic approach in the construction of the model, the respect for the evolutionary nature of architectural design, and the use of actual and complete design cases to test the model. Key words: CAAD, product modelling, integrated design environment, MERODE 1 The IDEA+ project: towards an integrated design environment In spite of the extensive use of all kinds of hardware and software in the architectural offices, the use of computers still does not contribute essentially to better architecture. For the CAD packages on the one hand, they have proven to be an efficient alternative for the traditional drawing board. Yet they fail in the early conceptual stage of design where creativity and exploration play the leading role. For computational tests and analysis tools on the other hand, they can hardly handle the typical absence o

title	Towards an integrated set of design tools based on a common data format for building and services design
source	Automation in Construction 10 (4) (2001) pp. 459-476
summary	The emerging technology in building product design using knowledge-based engineering (KBE), is currently exciting practitioners in the building construction industry. This paper investigates the use of KBE techniques and assesses the contribution this approach can make to the traditional design process. To do this, the investigation has developed an integrated set of design tools based on a common data format, for integrating 3D electronic prototypes with building services information for use in building design. This approach has been developed on the basis of an open framework and has been applied to the design of an airport terminal building and its plant room. Within the framework, the design process and the information needed, are divided into modules and represented in the form of 3D digital mock-up models (or electronic prototypes). Within the integrated system, an interface has been developed to facilitate the sharing of information with a thermal analysis software application, which contributes to the design process. In this paper, the methodology is discussed and its working system is illustrated and evaluated.

title	Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 695-704

summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	Several commercial real-estate sites provide listings of available commercial property on the Internet. These listings are generated on the basis of selection criteria as floor area, price and location. Despite the obvious utility of the listings and their promise for the transaction process and market transparency, one third of commercial realestate listing sites went bankrupt in 2001 and 2002. To provide an explanation for the failure, 63 commercial real-estate sites were analysed and classified into three basic business models: the Research / Information model, the Marketing model and the Transaction model. A common success factor for all models is the functionality of the site, especially interaction between the user and the available information. The paper proposes that the transfer of existing architectural representations, information-processing instruments and decision-taking tools is an essential component of future development towards integrated services that accompany a building throughout its lifecycle. This transfer amounts to (1) the addition of building and contextual information from standard documentation and online information services, (2) the derivation and coherent description of programmatic requirements database, and (3) advanced user interaction with building information.

title	Planning-oriented building surveying - Modules in the computer aided architectural planning process of existing buildings

summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. Current approaches to these issues are unsatisfactory. Methods and techniques in renovation work are being investigated as part of ongoing research at the Bauhaus- Universität Weimar (SFB524 - “Collaborative research center 524 „Materials and Structure in Revitalization of Buildings”). A sub-group (SFB524 - D2 „Planning-Relevant Digital Building Surveying and Information System”) is currently investigating the possibilities of computer-aided building surveying and of joint communcation platforms for engineering disciplines (www.uni-weimar.de/sfb: May 2001). The objective is the development of a general approach for the renovation of buildings. The paper discusses concepts and requirements for a computer-aided system supporting the entire surveying process from the initial site visit to its use in a CAD system.

title	Evaluation of Design Performance through Regional Environmental Simulation

summary	Computational building simulation tools have historically viewed buildings as artefacts isolated and disconnected from their contexts. At most, the external environmental conditions have been viewed as outside influences or stressors encapsulated in, for example, weather files for energy simulation or sky models for lighting simulation. In the field of environmental assessment, life cycle analysis (LCA) has followed a similar path of isolating the artefact under analysis from its context. Modeling the building artefact as a participant in multiple contexts over time so that the interactions and dependencies between the regions and the building can be adequately explored in the design process requires support for the modeling of regional areas, as well as the artefact and the related life cycle processes. Using computational design and evaluation tools can provide the computing capability required for effective design decision support. This paper presents the implementation of the affordance impact assessment method and the regional environmental simulation in Ecologue. Ecologue is the computational tool for life cycle environmental impact assessment in the SEMPER integrated building design and simulation system. Ecologue contains a building model and an environmental model. The building model is automatically derived from the shared building model of the SEMPER system. The environmental model is a combination of a representation of the processes and emissions occurring in the life cycle of buildings and an impact assessment model. The impact assessment model is a combination of a context model of the physical characteristics of a region and a sub-regional fate and transport model based on the fugacity concept.
