title Computers for Windows: Interactive Optimization Tools for Architects designing openings in walls (IOTA)

summary Size, shape and disposition of windows in walls has long been an integral expression of style in architecture. As buildings have grown taller the relationships of the windows to the ground plane and to the surrounding environments have become more complex and difficult to predict. Traditionally architects have had to use their own knowledge, experience and feelings in the design of windows. There may be few, if any, scientific bases for their decisions. The difficulty in making good design decisions is compounded because many criteria for window design, such as daylight, sunlight, ventilation, sound, view and privacy have to be considered simultaneously. It is here that computers can help, on the one hand, by providing ‘expert knowledge’ so that architects can consult the cumulative knowledge database before making a decision, whilst on the other hand, evaluations of the decisions taken can be compared with a given standard or with alternative solutions.

‘Expert knowledge’ provision has been made possible by the introduction of hypertext, the advancement of the world wide web and the development of large scale data-storage media. Much of the computer’s value to the architects lies in its ability to assist in the evaluation of a range of performance criteria. Without the help of a computer, architects are faced with impossibly complex arrays of solutions. This paper illustrates an evaluation tool for two factors which are important to the window design. The two factors to be investigated in this paper are sunlighting and views out of windows.

Sunlight is a quantitative factor that can theoretically be assessed by some mathematical formulae provided there is sufficient information for calculation but when total cumulative effects of insolation through the different seasons is required, in addition to yearly figures, a design in real-time evolution requires substantial computing power. Views out of windows are qualitative and subjective. They present difficulties in measurement by the use of conventional mathematical tools. These two fields of impact in window design are explored to demonstrate how computers can be used in assessing various options to produce optimal design solutions. This paper explains the methodologies, theories and principles underlying these evaluation tools. It also illustrates how an evaluation tool can be used as a design tool during the design process.

title Multimedia Training "Designing Randstad"
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The project multimedia training "Designing Randstad" (MTDR) is an experimental attempt to introduce multimedia in education at the Faculty of Architecture in Delft. It intends to develope teachware which will learn the students the basics of Geographic Informational Systems (GIS) implementation in land use evaluation appropriate for physical planning purposes. Interaction between students and the system will enable students to learn about GIS, to design a model of the spatial development of Randstad area and to evaluate their own designs, to produce immediate graphic visualisation of the evaluation and to compare it with the evaluations of the fellow students. The project will be applied in the first year curriculum, in the course "Region" of the Department of Urban planning of the Faculty of Architecture, in the first half of the year 1997.

title A Computer-Aided Evaluation Tool for the Visual Aspects in Architectural Design for High-Density and High- Rise Buildings
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 345-356
summary The field of view, the nature of the objects being seen, the distances between the objects and the viewer, daylighting and sunshine are some major factors affecting perceived reactions when viewing through a window. View is one major factor that leads to the satisfaction and comfort of the users inside the building enclosure. While computer technologies are being widely used in the field of architecture, designers still have to use their own intelligence, experience and preferences in judging their designs with respect to the quality of view. This paper introduces an alternative approach to the analysis of views by the use of computers. The prototype of this system and its underlying principles were first introduced in the C A A D R I A 1997 conference. This paper describes the further development of this system where emphasis has been placed on the high- rise and high-density environments. Architects may find themselves facing considerable limitations for improving their designs regarding views out of the building under these environmental conditions. This research permits an interactive real-time response to altering views as the forms and planes of the building are manipulated.

title Observations from an experimental study of computer-mediated collaborative design
source M.L. Maher, J.S. Gero, and F Sudweeks eds. Preprints Formal Aspects of Collaborative CAD, Key Centre of Design Computing, University of Sydney, Sydney, pp.165-185
summary The use of computer technology in design practice is moving towards a distributed resource available to a team of designers. The development of software to support designers has been based largely on the assumption that there will be a single person using the software at a time. Recent developments have enabled the feasibility of software for two or more simultaneous users, leading to the possibility of computer-mediated collaborative design. Research in integrated CAD, virtual design studios, and design protocol studies provide the basis for a formal study of computer-mediated design. We develop an experimental study of computer-mediated collaborative design with the aim of collecting data on the amount and content of design semantics documented using computer applications when designing alone as compared to designing collaboratively. The experiment includes the definition of an hypothesis, aim, methodology, data collection and coding schemes. The experiment and some preliminary observations are presented, followed by directions for further research.

title Modelling for eye level composition; design media experiments in an educational setting.
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 In order to simulate the visual effects of designs at eye level, it is necessary to construct models from which (sequences of) images can be taken. This holds true for both Optical Endoscopy and Computer Aided Visualisation techniques. In what ways can an eye level approach stimulate spatial awareness and create insights into the workings of a design concept? Can Endoscopic methods be used effectively as a creative environment for design decision-making and teamwork and even to stimulate the generation of new design ideas? How should modelmaking be considered if it is to be of use in an ‘impatient’ design process, and how can students be made aware of the opportunities of both direct eye level observations from design models and of the more sophisticated endoscopic imaging techniques? This paper explores the theme of eye level modelling by focusing on a number of formal exercises and educational experiments carried out by the Delft Media group in recent years. An attempt is made to describe and evaluate these experiences, in order to draw conclusions and to signal possible new opportunities for eye level composition for the benefit of both design education and practice...

summary Computer assistants to building design are more and more oriented to construct repertories of cases to be recalled as possible suggestions to a real design situation. For this purpose it is necessary that the cases be described by the parameters most apt to describe the design situations. In this way it will be possible to extract out of the repertory the existing case most akin to the design problem the designer is dealing with. This kind of help is the most fit to the usual behaviour of a designer which, in order to find the best solution to a design problem, resort to his culture, his knowledge of real cases, which he tries to adapt to the peculiar need of his present case. This paper presents an attempt to construct such a tool also if restricted to only one building component: the exterior brickwork. It is structured as an Hypertext, which allows a net of relationships much richer than the one of a conventional handbook.

title Semantically Rich Building Representation

source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 207-227
summary At the core of any computational system that can support design development, analysis, and evaluation is a building representation which should be able to represent all the different components that make up a building, along with the manner in which they come together. In other words, the representation must be informationally complete and semantically rich. The paper discusses these two criteria in detail, and briefly reviews other research efforts aimed at developing building representations for CAAD that attempt to meet them. Our solution to this problem is then presented. It is aimed primarily at the schematic design phase, the rationale for which is also stated. Taking the view that buildings are unique assemblies of discrete, mostly standardized components, our representation is clearly divided into two components: the Object Database (ODB) which stores detailed information about various building elements, and the Project Database (PDB) which holds information about how these elements are assembled to make up a particular building. An ODB may be shared by many building projects, while the PDB must necessarily be unique to each. The data schemas of both the PDB and the ODB are described in detail and their computational implementation, to the extent that it has been completed, is illustrated.

title Beyond Photorealism
source Architects’ Journal, 12/6/97
summary Computer rendering has come a long way in the last twenty years. But is it going in the right direction? Is the glossy photo-realistic image the only goal worth pursuing? And does the process of making it contribute enough to the design, or the ongoing dialogue with the client? There certainly are alternative modes of image-making. Frank Lloyd Wright, according to legend, could conceive a whole building in his head, and set it down rapidly, in plan and section. He would leave these drawings overnight to his assistant, who would set up a perspective. In the morning, FLW would spend an hour or two completing the rendering, ready for a lunch-time meeting with his clients. Today, many architects use their computers in the same way as FLW used his night-staff, to set-up an outline perspective, over which a rendering is produced by hand. Students, we observe, will often attempt to complete the rendering using a paint program such as Photoshop to apply textures and entourage in a kind of electronic collage.

summary Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology.

In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry.

The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards.

The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established.

Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry.

Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

title Computer analysis of visual perception - endoscopy without endoscope
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 This paper presents a method of using computer animation techniques in order to solve problems of visual pollution of city environment. It is our observation that human-inducted degradation of city environmental results from well - intentioned but inappropriate preservation actions by uninformed designers and local administration. Very often, a local municipality administration permits to build bad-fitting surroundings houses. It is usually connected with lack of visual information's about housing areas of a city, its features and characteristics. The CAMUS system (Computer Aided Management of Urban Structure) is being created at the Faculty of Architecture of Bialystok Technical University. One of its integral parts is VIA - Visual Impact of Architecture. The basic element of this system is a geometrical model of the housing areas of Bialystok. This model can be enhanced using rendering packages as they create the basis to check our perception of a given area. An inspiration of this approach was the digital endoscopy presented by J. Breen and M. Stellingwerff at the 2nd EAEA Conferences in Vienna. We are presenting the possibilities of using simple computer programs for analysis of spatial model. This contribution presents those factors of computer presentation which can demonstrate that computers achieve such effects as endoscope and often their use be much more efficient and effective.

summary The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.

summary Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

summary Windows in buildings must respond to five major issues – daylight, sunshine, view, ventilation and sound. Each of these processes in its own way can be critical to the synthesis of a successful architectural design. All factors except view are engineering criteria that can be evaluated by some mathematical formulae provided there is sufficient information for the calculations. In contrast view” being a qualitative entity has difficulty in being measured by using conventional mathematical tools but it is probably the major factor that leads to the satisfaction and comfort of the users inside the building enclosure. This paper introduces a new approach in analyzing views by the use of computers. One of the advantages of this analysis process is that the psychological aspects are less biased in the end product. This paper explains the methodologies, theories and principles underlying these modeling and analyzing tools.

summary In this case study we observed an experimental cooperative design project: a parking lot design using a video conference system. Twelve graduate students of planning and design were divided into two teams for landscape design and traffic planning. They used ProShareTM, a computer-supported video conference system, to co-design at two separate rooms. We used video equipment to record this conference for a detailed analysis. Some experiences on using this system are described. The results indicate the relationships within the work organization, physical workplace and cooperative design. We argued that this workplace becomes more important, even though much research has put emphasis on the cyberspace in cooperative design. The team members’ tacit protocol has importance, but it does not guarantee any resolution of conflicts. This cooperative design is not only a social process, but also a logic of iterative verifications and falsifications. It is dangerous to construct a theory of computer-supported cooperative design simply based on this case study; however, such an observation could be the first step towards the theory.

summary The use of computer technology in design practice is moving towards a distributed resource available to a team of designers. The development of software to support designers has traditionally been based on the assumption that there will be a single person using the software at a time. Recent developments have enabled the feasibility of software for two or more simultaneous users, leading to the possibility of computer mediated collaborative design (CMCD), where the computer plays the role of mediator and design information handler. There is the potential for the computer to play a more active role in collaborative design through enhanced visibility of 3D models and assistance in generating alternative designs and design critiques. With this potential the computer not only mediates the collaborative design process but actively supports the designers. Research in integrated CAD, multimedia and design database systems, virtual design studios, and design protocol studies provide the basis for a formal study of CMCD. We have developed an experimental methodology to study the difference in design semantics documented using computer applications when designing alone as compared to designing collaboratively. This methodology can be applied to study other aspects of CMCD.

title Performance Analysis and Conceptual Design
source School of Architecture and Fine Arts, University of Western Australia
summary A significant amount of the research referred to by Manning has been directed into the development of computer software for building simulation and performance analysis. A wide range of computational tools are now available and see relatively widespread use in both research and commercial applications. The focus of development in this area has long been on the accurate simulation of fundamental physical processes, such as the mechanisms of heat flow though materials, turbulent air movement and the inter-reflection of light. The adequate description of boundary conditions for such calculations usually requires a very detailed mathematical model. This has tended to produce tools with a very engineering-oriented and solution-based approach. Whilst becoming increasingly popular amongst building services engineers, there has been a relatively slow response to this technology amongst architects. There are some areas of the world, particularly the UK and Germany, where the use of such tools on larger projects is routine. However, this is almost exclusively during the latter stages of a project and usually for purposes of plant sizing or final design validation. The original conceptual work, building form and the selection of materials being the result of an aesthetic and intuitive process, sometimes based solely on precedent. There is no argument that an experienced designer is capable of producing an excellent design in this way. However, not all building designers are experienced, and even fewer have a complete understanding of the fundamental physical processes involved in building performance. These processes can be complex and often highly inter-related, often even counter-intuitive. It is the central argument of this thesis that the needs of the building designer are quite different from the needs of the building services engineer, and that existing building design and performance analysis tools poorly serve these needs. It will be argued that the extensive quantitative input requirement in such tools acts to produce a psychological separation between the act of design and the act of analysis. At the conceptual stage, building geometry is fluid and subject to constant change, with solid quantitative information relatively scarce. Having to measure off surface areas or search out the emissivity of a particular material forces the designer to think mathematically at a time when they are thinking intuitively. It is, however, at this intuitive stage that the greatest potential exists for performance efficiencies and environmental economies. The right orientation and fenestration choice can halve the airconditioning requirement. Incorporating passive solar elements and natural ventilation pathways can eliminate it altogether. The building form can even be designed to provide shading using its own fabric, without any need for additional structure or applied shading. It is significantly more difficult and costly to retrofit these features at a later stage in a project’s development. If the role of the design tool is to serve the design process, then a new approach is required to accommodate the conceptual phase. This thesis presents a number of ideas on what that approach may be, accompanied by some example software that demonstrates their implementation.

Within the ambit of O.R., Mathematical Programming. deals with decisional problems of simplest structure: only one decision factor, only one preference function, complete (deterministic) knowledge of the environment in which one operates.

Such a problem, in standard form, presents an objective function Z=f(x), of n variables x, to be minimized and a system of linear equations and/or inequalities, on the same variables, which represent the constraints and which define an admissible area for the solution.

The architectural organism is modelled as an assembly of parallelepiped shaped space entities or units, provided with a certain number of "holes" that permit functional corresponding connection. The pursued intent being optimal assembly.

The model, in its mathematical form, fits a standard Non-Linear M.P. (N.L.P.) problem, since the objective function Z is non-linear and the constraints are represented by inequalities. In its graphic form it reproduces an image of all the space units constituting the organism; moreover it is able to represent these units, in their logical and physical individuality, and their mutual relationship, as well as the ones with the external environment.
