title Integrating Design Tools within a Human Collaborative Working Context
source International Journal of Construction IT, Vol5, No 2, pp 35-53
summary Integrating design tools has been an important research subject. The work to be reported in this paper differs from many previous efforts in that it not only tackles tool-tool interoperation, but also does so within a human collaborative working context We suggest that design integration support should include not only tool interoperability, but also mechanisms for co-ordinate and control the tool use. We also argue that the higher-level management support should include not only formalised and automated mechanisms, but also semi-automated and even informal mechanisms for human designers to directly interact with each other. Within a collaborative working framework, we'll present a hybrid architecture for tool integration, in which the human designers and the design tools are assumed to be distributed while the management is centralised. In this approach, each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A meta-data augmented product model, which populates a central meta-data repository serving as a "map" for locating the distributed design objects, is devised to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. A design object broker is used to mediate among the distributed tools, and the central meta-data repository. The reported work has been part of a collaborative design system called virtual studio environment We'll illustrate how the integrated design tools might be used in human design work within the virtual studio environment.

title Architecture in Landscape: Integrated CAD Environments for Contextually Situated Design
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi https://doi.org/10.52842/conf.ecaade.1997.x.q6p
summary This paper explores the future role of a more holistic and integrated approach to the design of architecture in landscape. Many of the design exploration and presentation techniques presently used by particular design professions do not lend themselves to an inherently collaborative design strategy.

Within contemporary digital environments, there are increasing opportunities to explore and evaluate design proposals which integrate both architectural and landscape aspects. The production of integrated design solutions exploring buildings and their surrounding context is now possible through the design development of shared 3-D and 4-D virtual environments, in which buildings no longer float in space.

The scope of landscape design has expanded through the application of techniques such as GIS allowing interpretations that include social, economic and environmental dimensions. In architecture, for example, object-oriented CAD environments now make it feasible to integrate conventional modelling techniques with analytical evaluations such as energy calculations and lighting simulations. These were all ambitions of architects and landscape designers in the 70s when computer power restricted the successful implementation of these ideas. Instead, the commercial trend at that time moved towards isolated specialist design tools in particular areas. Prior to recent innovations in computing, the closely related disciplines of architecture and landscape have been separated through the unnecessary development, in our view, of their own symbolic representations, and the subsequent computer applications. This has led to an unnatural separation between what were once closely related disciplines.

Significant increases in the performance of computers are now making it possible to move on from symbolic representations towards more contextual and meaningful representations. For example, the application of realistic materials textures to CAD-generated building models can then be linked to energy calculations using the chosen materials. It is now possible for a tree to look like a tree, to have leaves and even to be botanicaly identifiable. The building and landscape can be rendered from a common database of digital samples taken from the real world. The complete model may be viewed in a more meaningful way either through stills or animation, or better still, through a total simulation of the lifecycle of the design proposal. The model may also be used to explore environmental/energy considerations and changes in the balance between the building and its context most immediately through the growth simulation of vegetation but also as part of a larger planning model.

The Internet has a key role to play in facilitating this emerging collaborative design process. Design professionals are now able via the net to work on a shared model and to explore and test designs through the development of VRML, JAVA, whiteboarding and video conferencing. The end product may potentially be something that can be more easily viewed by the client/user. The ideas presented in this paper form the basis for the development of a dual course in landscape and architecture. This will create new teaching opportunities for exploring the design of buildings and sites through the shared development of a common computer model.

title ADELINE, an Integrated Approach to Lighting Simulation
source Proceedings of Right Light 4, 4th European Conference on Energy-Efficient Lighting, pp.99-103
summary The use of daylighting and artificial lighting simulation programs to calculate complex systems and models in the design practice often is impeded by the fact that the operation of these programs, especially the model input, is extremely complicated and time-consuming. Programs that are easier to use generally do not show the calculation capabilities required in practice. A second obstacle arises as the lighting calculations often do not allow any statements regarding the interactions with the energetic and thermal building performance. Both problems are mainly due to a lacking integration of the design tools of other building design practitioners as well as due to insufficient user interfaces. The program package ADELINE (Advanced Daylight and Electric Lighting Integrated New Environment) being available since May 1996 as completely revised version 2.0 presents a promising approach to solve these problems. This contribution describes the approaches and methods used within the international project IEA Task 21 for a further development of the ADELINE system. Aim of this work is a further improvement of user interfaces based on the inclusion of new dialogs and on a portation of the program system from MS-DOS to the Windows NT platform. Additional focus is laid on the use of recent developments in the field of information technology and experiences gained in other projects on integrated building design systems, like for example EU-COMBINE, in a pragmatical way. An integrated building design system with open standardized interfaces is to be achieved inter alia by using ISOSTEP formats, database technologies and a consequent, object-oriented design.

doi https://doi.org/10.52842/conf.acadia.2018.226
summary From the “Edge of Chaos”, a mathematical space discovered by computer scientist Christopher Langton (1997), compelling behaviors originate that exhibit both degrees of organization and instability creating a continuous dance between order and chaos. This paper presents a project intended to make this complex theory tangible through an interactive installation based on metamaterial research which demonstrates emergent behavior using Cellular Automata (CA) techniques, illustrated through sound, light and motion. We present a multi-sensory narrative approach that encourages playful exploration and contemplation on perhaps the biggest questions of how life could emerge from the disorder of the universe.

We argue a way of creating intelligent architecture, not through classical Artificial Intelligence (AI), but rather through Artificial Life (ALife), embracing the aesthetic emergent possibilities that can spontaneously arise from this approach. In order to make these ideas of emergent life more tangible we present this paper in four integrated parts, namely: narrative, material, hardware and computation. The Edge of Chaos installation is an explicit realization of creating emergent systems and translating them into an architectural design. Our results demonstrate the effectiveness of a custom CA for maximizing aesthetic impact while minimizing the live time of architectural kinetic elements.

title Towards Comprehensive Space: A context for the programming/design of cybrids
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 161-171
doi https://doi.org/10.52842/conf.acadia.2003.161
summary Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture’s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should be integrated with material structures requires that their relationship be developed from the outset of a project. Hence, this paper provides a method for their integration from the project’s earliest stages, the establishment of its program. This study for an actual project, the Planetary Collegium, describes a distributed campus comprising buildings and cyberspaces in various locales across the globe. The programming for these cybrids merges them within a comprehensive space consisting not only of the physical and cyberspaces, but also in the cognitive spaces of its designers and users.

doi https://doi.org/10.52842/conf.ecaade.1997.x.m9r
summary This paper presents a virtual reality interface tool which allows a user to perform the following action :

1.Import design from other CAD tools.

2.Assemble an architecture structure from a library of pre-built blocks and geometry primitives dynamically created by user.

3.Export the design interactively in VRML format back to the library for Internet browsing.

The geometry primitives include polygon, sphere, cone, cylinder and cube. The pre-built blocks consist of fundamental architecture models which have been categorized with architectural related style, physical properties and environmental attributes. Upon a user’s request, the tool or the composer, has the ability to communicate with the library which indeed is a back-end distributed client-server database engine. The user may specify any combination of properties and attributes in the composer which will instantly bring up all matching 3-dimensional objects through the database engine. The database is designed in relational model and comes from the work of another research group.

title Hierarchical Decomposition of Architectural Computer Models
source CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 197-203
doi https://doi.org/10.52842/conf.caadria.1997.197
summary Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

title Integrating Design Tools within a Human Collaborative Working
source The Int. Journal of Construction IT 5(2), pp. 47-73
summary This paper stresses the importance of establishing a collaborative working context as the basis for design integration. Within a virtual studio environment framework, a hybrid architecture for design tool integration is presented. Each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A global product model, which is augmented with meta-data description, is employed to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. Collaboration-aware information is modelled and structured through the meta-data model and a tool model. Based on this, mechanisms for tool service coodination in varying modes are developed. It is then illustrated, through an implemented prototype system, how the integrated design tools might be used in human design work.

title Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title Adaptive architecture: integrating low-energy technologies for climate control in the desert
source Automation in Construction 6 (5-6) (1997) pp. 417-425
summary The article describes a `climatically adaptive' approach to intelligent building in which a variety of technologies are integrated in the architectural design to provide thermal comfort with a minimal expenditure of energy. This concept is illustrated by the design of the Blaustein International Center for Desert Studies, a multi-use complex completed recently at the Sede-Boker Campus of Ben-Gurion University of the Negev. In response to the local climate of this desert region, a number of strategies were developed by the authors to exploit natural energy for heating and cooling: earth berming of major parts of the building, 'selective glazing' for seasonal shading and energy collection, a down-draft 'cool-tower' for evaporative cooling and a hybrid mechanism for hot-air supply are several of the unique systems whose performance and feasibility are analyzed within the context of the overall building design.

summary This paper reports on findings of a November 1996 exploratory survey of architecture-engineering clients (Fortune 500 corporate facility managers). This research investigated how the practices of corporate facility managers are being influenced by rapid changes in information technology. The conceptual model that served as a guide for this research hypothesized that information technology acts as both an enabler (that is, information technology provides an effective mechanism for managers to implement desired changes) as well as a source of innovation (that is, new information technology innovations create new facility management opportunities). The underlying assumption of this research is that information technology is evolving from a tool that incrementally improves "back-office" productivity to an essential component of strategic positioning that may alter the basic economics, organizational structure and operational practices of facility management organizations and their interactions with service providers (architects, engineers and constructors). The paper concludes with a discussion of researchable issues.

summary This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.

summary This paper discusses the impact of a continuously developing CAAD learning strategy, describing in detail a few of these principles, and considering their dynamic impact through deeper more lasting learning, feeding a substantial intensification in the application of Architectural Designing with Computers, changing design methods with interesting analytical and creative results.Aspects of the CAAD teaching discussed include extended collaboration between CAAD and design tutors in defining learning outcomes and tutoring the students’ application of CAAD to design projects, inclusion of CAAD within traditional interim reviews and feedback for design projects and bringing emphasis on conceptual principles, structuring the model and simple programming into earlier stages of the teaching programme and a simple excursion into programming. Studio project examples indicate the interplay between teaching, learning and achievement. Some evidence is explored in greater detail. from the "Interstitial Layers" project utilising the appropriateness of CAAD to store and switch the visibility of spatial data in endless permutations and extensive combinations for mapping, analysing and strategically projecting patterns of city centre activities, fabric and space. Students’ demonstrate a dynamic command of CAAD: as a vehicle for conceptual design, a device to analytically review, criticise and modify the design, as a means to explain design ideas to tutors and to develop and detail final building designs. Reciprocal valuing of quality CAAD achievement between architecture students and staff is seen to be contributing to involvement and motivation, reinforcing striving for equality of achievement. Reference to a further strand of the new methodology considers the impact of tutoring based in researcher findings from video case study precedents of architects practising creative design through use of computers, on a more open, effective development of the architecture students’ own designing processes, culminating in interesting design work.

title High-end developments within the framework of dynamic-endoscopic viewing of models.
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary As far back as the seventies the first experiences with endoscopic viewing of models were made in the field of architecture and urban construction by introducing an endoscope into the model of the planned architectural and urban space. The monitor shows an approximation of real view of the new portion of building or city, resp. The endoscopic picture provides the viewer with the usual height of viewing and roughly the perspective of a pedestrian, whereas very often planning models of houses and city quarters are evaluated predominantly by means of the bird's eye view. Meanwhile, mechanical installations of relatively limited means have been installed at several university sites making for a simulation of spatial experience by means of endoscopic rides through a construction model such as from the view of a car driver. This paper presents a sketch for a research proposal which is aimed at anticipating high-end-developments based on the experience acquired so far using low-cost-simulations.

summary This paper concretely presents the design processes and results of Composer Tod Machover's Brain Opera, an interactive, multi-media, traveling opera. It will present the importance of successful collaboration between artists and scientists at the functional intersection of their research -- design. It will discuss the opposing design strategies necessary for integrating technology into the physical environment at various levels of scale, from architecture to interface. At the level of architecture flexibility in design is stressed. In interface design, the needs for specificity and detail, new materials and manufacturing processes are presented. The paper will demonstrate how the aesthetic goals of the Brain Opera's visual designers, creating an organic, humorous and unexpected technology environment, influenced audience interaction. The conflict between artistic control and interactivity will also be examined through the specific results of acoustic design in the project. The influences of quickly changing technology and funding on the design of the Brain Opera are also revealed. The prominence of the proscenium arch stage in existing music venues and its influence on new media projects is presented. Successful and unsuccessful models for audience participation are also presented. Concrete interface examples are used to counter the notion of intuitive interface design. Finally, the Brain Opera is presented as a design model for an interactive research laboratory.

doi https://doi.org/10.52842/conf.acadia.1997.111
summary When spaces are evaluated, clients and architects often discuss design proposals by looking down at scale models. This overhead perspective forces viewers to imagine themselves looking and moving about within the model. Misperceptions may well result from such a point of view. With the advancement in virtual reality (VR) technology, and with its rising popularity in architecture, it is becoming plausible to consider using VR to evaluate design projects.

The projects presented here are of three types: (1.) The first project compares people's evaluation of several slightly modified virtual models of a space. (2.) The second project compares how people evaluate a foam core model of a space to how they evaluate a virtual representation of the same space (3.) The third project compares people's evaluation of a real space to that of a virtual representation of this space. //

The wide range of results presented provides one argument in support of using VR simulations to study spaces and how they are perceived. For example, results shows that a virtual window serves to alleviate perceived crowding and that added furniture serves to make a virtual room feel slightly larger and less constraining. However, problems did emerge with using virtual reality simulations to gain information about peoples' behavioral reactions to a space. Thus, not all circumstances under which VR representations are used creates valid results. Differences appear to be in the type of evaluations measured (e.g. dimensional versus behavioral). More research is needed to clarify this issue.

summary The graphic intention is a peculiarity of the architectural drawing. It is enough to compare the ground plan of an unifamiliar housing insulated of Le Corbusier with another of Mies van der Rohe to realise the diversity of graphic styles, but is important to take conscience of the complexity that carries to interpret the symbols that appear in those documents, because as architects we either realize plans that the instructions are described or measures to be able to execute the work and in other occations representations for his edition aimed to a especialized public.

For this reason, and because not always is arranged the best possible documentation, we consider that the majority of vectorisations they exist in the market don’t plenty satisfied our needs as teaching staff of graphic expression and CAD, althoug we can always be using the same systems of projection or codified representations, it is imposed a lot of times to interpret acording the context the different signs and graphic registers used.

We know experimental applications that go beyond, they even arrive to generate a 3D model from a lifted hand draw that represents three orthogonal projections of it, but it isn’t less certain that its utility is restricted to fields very specialised and the option that we propose, there is not knowledge at least to us that it exist; commercially speaking.

Our porpose has been to develope a symple metedology of vectorisation but adapted to the special idiosyncrasy of the needs of an architecture student that with frequency for his formation requires to generate with CAD models 2D and 3D of architectural projects from the information contented in magazines, and with them create several formas analysis.

The most important difference in the matter to other systems is the interactivity of the procedure that let personify the exit file, even the wide diversity of graphic registers that it exist in the entrance, being the user only once has to identify and interpret the signs to detect, and then the process is realized automatically to any plant of the building or equivalent projection.

title Computer-Aided Design and Manufacturing of Complex Shaped Concrete Formwork
source Doctor of Design Thesis, Graduate School of Design, Harvard University, Cambridge, MA
summary The research presented in this thesis challenges the appropriateness of existing, conventional forming practices in the building construction industry--both in situ or in prefabrication--for building concrete "freeforms," as they are characterized by impracticality and limitations in achieved geometric/formal quality. The author's theory proposes the application of alternative, non-traditional construction methods derived from the integration of information technology, in the form of Computer-Aided Design (CAD), Engineering (CAE) and Manufacturing (CAM), into the concrete tooling and placing process. This concept relies on a descriptive shape model of a physically non-existent building element which serves as a central database containing all the geometric data necessary to completely and accurately inform design development activities as well as the construction process. For this purpose, the thesis orients itself on existing, functioning models in manufacturing engineering and explores the broad spectrum of computer-aided manufacturing techniques applied in this industry. A two-phase, combined method study is applied to support the theory. Part I introduces the phenomenon of "complexity" in the architectural field, defines the goal of the thesis research and gives examples of complex shape. It also presents the two analyzed technologies: concrete tooling and automation technology. For both, it establishes terminology, classifications, gives insight into the state-of-the-art, and describes limitations. For concrete tooling it develops a set of quality criteria. Part II develops a theory in the form of a series of proposed "non-traditional" forming processes and concepts that are derived through a synthesis of state-of-the-art automation with current concrete forming and placing techniques, and describes them in varying depth, in both text and graphics, on the basis of their geometric versatility and their appropriateness for the proposed task. Emphasis is given to the newly emerging and most promising Solid Freeform Fabrication processes, and within this area, to laser-curing technology. The feasibility of using computer-aided formwork design, and computer-aided formwork fabrication in today's standard building practices is evaluated for this particular technology on the basis of case-studies. Performance in the categories of process, material, product, lead time and economy is analyzed over the complete tooling cycle and is compared to the performance of existing, conventional forming systems for steel, wood, plywood veneer and glassfiber reinforced plastic; value s added to the construction process and/or to the formwork product through information technology are pointed out and become part of the evaluation. For this purpose, an analytical framework was developed for testing the performance of various Solid Freeform Fabrication processes as well as the "sensitivity," or the impact of various influencing processes and/or product parameters on lead time and economy. This tool allows us to make various suggestions for optimization as well as to formulate recommendations and guidelines for the implementation of this technology. The primary objective of this research is to offer architects and engineers unprecedented independence from planar, orthogonal building geometry, in the realization of design ideas and/or design requirements for concrete structures and/or their components. The interplay between process-oriented design and innovative implementation technology may ultimately lead to an architecture conceived on a different level of complexity, with an extended form-vocabulary and of high quality.

summary In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title Berlin-Crane City: Cardboard, Bits, and the Post-industrial Design Process

summary This paper explores the impact of information technology on the architectural design process as seen through different design studios from three schools of architecture in Southern California over a two year period.

All three studios tested notions of representation, simulation and the design process in relation to a post-industrial world and its impact on how we design for it. The sites for two of these studios were in the city of Berlin, where the spearhead of the information age and a leftover of the industrial revolution overlap in an urban condition that is representative of our world after the cold war. The three studios describe a progressive shift in the use of information technology in the design process, from nearly pure image-driven simulation to a more low-tech, highly creative uses of everyday computing tools. Combined, all three cases describe an array of scenarios for content-supportive uses of digital media in a design studio. The first studio described here, from USC, utilized computer modeling and visualization to design a building for a site located within the former no-mans' land of the Berlin Wall. The second studio, from SCI-Arc, produced an urban design proposal for an area along the former Berlin Wall and included a pan-geographic design collaboration via Internet between SCI-Arc/Los Angeles and SCI-Arc/Switzerland. The third and last studio from Woodbury University participated in the 1997 ACSA/Dupont Laminated Glass Competition designing a consulate general for Germany and one for Hong Kong. They employed a hybrid digital/non-digital process extracting experiential representations from simple chipboard study models and then using that information to explore an "enhanced model" through digital imaging processes.

The end of the cold war was coincidental with the explosive popularization of information technology as a consumer product and is poised to have huge impact on how and what we design for our cities. Few places in world express this potential as does the city of Berlin. These three undergraduate design studios employed consumer-grade technology in an attempt to make a difference in how we design, incorporating discussions of historical change, ideological premise and what it means to be an architect in a world where image and content can become easily disconnected from one another.
