title	On the Structure and Elements of SEMPER
doi	https://doi.org/10.52842/conf.acadia.1996.071
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 71-84
summary	This paper introduces the concept, structure, components, and application results of "SEMPER", an active, multi-aspect computational tool for comprehensive simulation-based design assistance. Specifically, SEMPER seeks to meet the following requirements: a) a methodologically consistent (first- principles-based) performance modeling approach through the entire building design and engineering process; b) seamless and dynamic communication between the simulation models and an object- oriented space-based design environment using the structural homology of various domain representations; and c) "preference-based" performance-to-design mapping technology (bidirectional inference). SEMPER involves the integrated computational modeling of heat transfer, air flow, HVAC system performance, thermal comfort, daylighting and electrical lighting, acoustics, and life-cycle assessment.

title	Integrated Energy Modeling for Computational Building Design Assistance
source	Carnegie Mellon University, Department of Architecture
summary	Insights into the importance of energy modeling in building design have not yet resulted in the sufficient and systematic use of modeling tools in practice. In recent years, there has been considerable discussion on the limitations of simulation tools, and there is a noteworthy consensus as to the nature of the contributing factors (material and time implications, problematic user-interfaces, inefficient data communication structures, poor integration with CAD systems, absence of 'active' design support). This thesis deals with three research questions that are especially pertinent to the quest for active, multi-aspect design and simulation environments: (1) The appropriateness and feasibility of a methodologically consistent performance modeling approach through the entire design process. (2) Strategies for a structurally 'seamless' containment of performance simulation within a computational design environment. (3) Technologies to facilitate dynamic and interactive performance-to-design mapping. At a paradigmatic level, this thesis critically examines the existing responses to each of these questions, and proposes alternative computational frameworks and technologies to overcome some of the system-immanent ('endogenous') limitations of the existing approaches. At an operational level, this thesis demonstrates the proposed solutions by implementing an active thermal simulation module (NOD

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.

title	An Outline of the Requirements for a Computer-Supported Collaborative Design System
source	Open House International, vol 21, no 1, March 1996
summary	Computer-Aided Architectural Design (CAAD) systems have adequately satisfied several needs so far. They have dramatically improved the accuracy and consistency of working drawings, enabled designers to visualize their design ideas in three-dimensions, allowed the analysis of designs through data exchange and integrated databases, and even allowed the designers to evaluate (and in some cases generate) designs based on comparisons to previous cases and/or the formalization of grammars. Yet, there is a consensus that CAAD systems have not yet achieved their full potential. First, most systems employ a single-user approach to solving architectural problems which fails to grapple with the fact that most design work is done through teamwork. Second, current systems still can not support early design stages which involve client briefing, data collection, building program formulation, and schematic design generation. This paper seeks to study remedies to both of the afore-mentioned limitations through focusing on the fundamental dialectic and collaborative nature of what is called designing: a concerned social activity that proceeds by creating architectural elements to address a set of requirements and their re-thinking as a result of architectural conjecture. To investigate this relationship, it is proposed to build a computer-supported collaborative design environment using the tools of conceptual modeling, object-oriented algorithms, and distributed agents. Based on findings regarding the role of artifacts in collaborative design and a literature survey, this paper concludes with an outline of the requirements for the above system.

title	The Continuing Dichotomy: Practice vs. Education
doi	https://doi.org/10.52842/conf.ecaade.1996.131
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 131-142
summary	While it is apparent from the architectural literature that some practices are innovative in their use of computers for architectural design, clear evidence indicates that most architectural practices have applied computing to traditional practice paradigms. Information technology is therefore being applied to practice systems which were in place prior to computers being available. This has significant implications for architectural education in which there is tension developing between the requirements of the commercially oriented architectural practice and the innovation driven computer-aided architectural design educator. The first wishes to equip graduates for immediate and productive employment in computerised architectural practices and may be loosely interpreted as a graduate’s ability to work as a CAD operator within an architectural practice environment. The second has the desire for students to be innovative in their use of information technology as an aid in informing and evaluating parts of both the design process and its outcomes. However, it is only when both architects and educators identify the architectural process as an integrated information system that these tensions can be resolved. This requires reconsideration of the function and use of information technology in both educational institutions and in architectural practices. The paper discusses how fruitful this can be in the current environment and outlines current developments at Deakin University which aim at providing a middle ground

title	The Right Tool at the Right Time - Drawing as an Interface to Knowledge Based Design Aids
doi	https://doi.org/10.52842/conf.acadia.1996.191
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 191-199
summary	Designers use different symbols and diagrams in their drawings to explore alternatives and to communicate with each other. Therefore, a useful design environment should attempt to infer the designer's intentions from the drawing and, based on this inference, suggest appropriate computational tools for the task at hand. For example, a layout bubble diagram might activate design cases with similar configurations. Scribbles of view lines on a floor plan might bring up a spatial analysis tool. This research aims to develop an integrated digital sketching environment to support early design activities. The paper proposes RT, an intelligent sketch environment that provides the designers with the right tools at the right time.

summary	This paper describes an on-going effort, initiated at Stanford's Civil Engineering Department, to develop, implement, and test a new and innovative "Computer Integrated Architecture./Engineering/Construction" (A/E/C) course. The course takes a multi-site, cross- disciplinary, project-centered, team-oriented approach to teaching. The paper presents the motivation, methodology, computational infrastructure, and initial observations in the experimental A/E/C course. The course is sponsored by NSF Synthesis Coalition and is the result of the collaborative effort of faculty and researchers from Civil Engineering Department at Stanford University, and Architecture Department and Civil Engineering Department, at UC Berkeley. In this computer integrated A/EIC environment a new generation of architecture, engineering, construction students learns how to team up with other disciplines and the advantage of the emerging information technologies for collaborative work in order to design and build higher quality buildings faster.

title	OPSALC: A computer-integrated operations planning system for autonomous landfill compaction
source	Automation in Construction 5 (1) (1996) pp. 39-50
summary	Construction workers and operators associated with sanitary waste landfilling operations face significant health risks because of high levels of exposure to harmful solids and gases. Automation of the spreading and compacting processes of a landfilling operation using an autonomous compactor can reduce exposure of workers to the harmful environment, and thereby lead to improved safety of workers. This paper describes a computer-integrated operations planning system that facilitates (1) the design of landfill cells and (2) the generation of area-covering path plans for spreading and compaction processes by the autonomous compactor. The partitioning of a given landfill site into three-dimensional cells is accomplished by a recursive spatial decomposition technique in which the cell sizes are determined using a probabilistic model for waste generation. A recursive sub-division of each cell into monominoes facilitates the system to automatically deal with any differences between the actual amount of waste generated on a particular day and the amount predicted by the probabilistic model. The partitioned configuration of the landfill site is used to generate the path plan for the autonomous compactor using three motion models, namely straight-up, straight-down, and zig-zag. The computer-integrated system is implemented using PHIGS graphics standard and MOTIF toolkit with C-program binding.

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title	The Building Design Advisor
doi	https://doi.org/10.52842/conf.acadia.1996.085
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 85-97
summary	The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, schematic design phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools. The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to any number of parameters addressed by the tools linked to the BDA. The BDA is implemented as a Windows-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA supplies “smart” default values from a Prototypical Values Database (PVD) for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE and the PVD, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia Case Studies Database (CSD). The next version of the BDA will be linked to additional tools, such as a photo-accurate rendering program and a cost analysis program. Future versions will address the whole building life-cycle and will be linked to construction, commissioning and building monitoring tools.

source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 325-334
summary	Although there is an important commitment to the use of Computer Aided Design (CAD) systems in the design studio, there are still technologies that are not broadly accepted as useful to the designer especially in the early design stage. This is because CAD systems use the monitor and mouse which differ from the sketch paper and pen of manual media. This presentation explores how CAD systems can be applicable and integrated to this early design stage by allowing paper as a digital medium. With this exploration, I look at some ways for bridging manual media and digital media. For accommodating this approach, this article includes the evaluation of a prototype CAD system that discusses enhancing the role of CAD systems in the early design stage and linking the realms of the two currently distinct media — manual and digital. This system allows the designer to work with computer based and paper based tools in the same conventional environment. The method provides interesting insights into the relationship between digital and manual media.

summary	At many schools of architecture the studies are directed to practical, professional use, and this fact results in different attitudes. But normally, it will be so that the longer the student goes in the study the more aspects from practice will be involved. Therefore, the studies passes from the work with the design itself and the more artistic sides to the work with planning and production. The basis of the educational progress and the professional level is research and development. Within CAD it is important that this research develops as well the theoretical foundation and includes experience in the practical use. An attitude which prioritizes the practical qualifications late in the studies has of course an effect in the CAD instruction. Tendencies to consider the computer to be a tool of drawing and visualization will dominate, and the work with structuralized information models for a general documentation has had minor interest until now, and this also includes the use of professional applications developed from different conventions in support of collaboration and quality control. The dialogue between the environment of education and research on one hand and the professional business in practice must be considered important for the developing process in the use of CAD and for the building of usable IT models. The work with "The Masonry House" and later "The Building Trade House" tries to expose how a deliberate structuralization of the CAD model early in the sketching- and planning process can support as well the more esthetic estimates as the building technology documentation. And also point out the professional qualifications bound up with 11 to be integrated in the study course.

title	Integrated Support Systems for Architectural Design
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Many software systems are used in the field of architectural design. On the other hand, we can state that there is a significant lack of integrated systems providing a general support for the designer during the whole design process from initiative till demolition. This research project deals with the development of such an integrated design support system. We consider a complete automation of architectural design as an unlikely proposition and undesirable for the architect. Therefore, the general objective is to give support to the architect to improve the quality and to increase the efficiency of the design process. So far there are different tools providing such functionality. Nevertheless, there are no appropriate tools for many of the sub-processes. Furthermore, the current state of available design software is characterised by a lack of integration of different tools. To overcome these two problems our research project involves the development of tools as well as it deals with the aspect of tool integration. We will give a general description of the support that software can offer to architects during the materialisation phase of design. We conclude that many different tools are needed which have to be integrated in an open, modular, distributed, user friendly and efficient environment.

summary	We suggest and motivate a system to support city traffic planning. Our approach is derived from Case-Based Reasoning (CBR), where former experiences (cases) are stored and made available for reuse. To start with, a collection of examples from books or other sources is stored as hypermedia documents. Retrieval of useful examples is enabled by describing (indexing) the examples in several aspects. While some descriptors have to be attached by users or system administrators, others could be automatically inferred. The vision is, that in the long run cases are derived from GIS plans and the CBR support is an integrated tool in a GIS working environment.

title	LIGHT AS LANGUAGE
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	With the unlimited supply of electric light our surroundings very easily may be illuminated too strongly. Too much light is unpleasant for our eyes, and a high level of light in many cases disturbs the conception of form. Just as in a forest, we need shadows, contrasts and variation when we compose with light. If we focus on the term compose, it is natural to conceive our environment as a wholeness. In fact, this is not only aesthetically important, it is true in a physical context. Inspired by old windows several similar examples have been built in the Trondheim Full-scale Laboratory where depth is obtained by constructing shelves on each side of the opening. When daylight is fading, indirect artificial light from above gradually lightens the window. The opening is perceived as a space of light both during the day and when it is dark outside. Another of the built examples at Trondheim University which will be presented, is a doctor's waitingroom. It is a case study of special interest because it often appears to be a neglected area. Let us start asking: What do we have in common when we are waiting to come in to a doctor? We are nervous and we feel sometimes miserable. Analysing the situation we understand the need for an interior that cares for our state of mind. The level of light is important in this situation. Light has to speak softly. Instead of the ordinary strong light in the middle of the ceiling, several spots are selected to lighten the small tables separating the seats. The separation is supposed to give a feeling of privacy. By the low row of reflected planes we experience an intimate and warming atmosphere in the room. A special place for children contributes to the total impression of calm. In this corner the inside of some shelves are lit by indirect light, an effect which puts emphasis on the small scale suitable for a child. And it also demonstrates the good results of variation. The light setting in this room shows how light is “caught” two different ways.

summary	In April of 1995 the Internet took a step into the third dimension with the introduction of the Virtual Reality Modeling Language (VRML) as a commercial standard. Another event that month caused fewer headlines but in retrospect was just as significant. A small company from San Francisco, Worlds Incorporated, launched WorldsChat, a three dimensional environment allowing any Internet user to don a digital costume, or avatar, and travel about and converse with other people inhabiting the space. WorldsChat was appropriately modeled on a space station complete with a central hub, hallways, sliding doors, windows, and escalators to outlying pods.

title	Conceptual Collaborative Building Design Through Shared Graphics
source	IEEE Expert special issue on Al in Civil Engineering, June vol. 33-41
summary	The Interdisciplinary Communication Medium computer environment integrates a shared graphic modeling environment with network-based services to accommodate many perspectives in an architecture/engineering/construction team. Communication is critical for achieving better cooperation and coordination among professionals in a multidisciplinary building team. The complexity of large construction projects, the specialization of the project participants, and the different forms of synchronous and asynchronous collaborative work increase the need for intensive information sharing and exchange. Architecture/engineering/construction (A/E/C) professionals use computers to perform a specific discipline's tasks, but they still exchange design decisions and data using paper drawings and documents. Each project participant investigates and communicates alternative solutions through representational idioms that are private to that member's profession. Other project participants must then interpret, extract, and reenter the relevant information using the conventional idioms of their disciplines and in the format required by their tools. The resulting communication difficulties often affect the quality of the final building and the time required to achieve design consensus. This article describes a computer environment, the Interdisciplinary Communication Medium (ICM), that supports conceptual, collaborative building design. The objective is to help improve communication among professionals in a multidisciplinary team. Collaborative teamwork is an iterative process of reaching a shared understanding of the design and construction domains, the requirements, the building to be built, and the necessary commitments. The understanding emerges over time, as team members begin to grasp their own part of the project, and as they provide information that lets others progress. The fundamental concepts incorporated in ICM include A communication cycle for collaborative teamwork that comprises propose-interpret-critique-explain-change notifications. An open system-integration architecture. A shared graphic modeling environment for design exploration and communication. A Semantic Modeling Extension (SME), which introduces a structured way to capture design intent. A change-notification mechanism that documents notes on design changes linked to the graphic models, and routes change notifications. Thus, the process involves communication, negotiation, and team learning.

Parks, Carol Johnston, David Maidment, Michael Crane, and Sandi Glendinning, Editors With growing pressure on natural resources and landscapes there is an increasing need to predict the consequences of any changes to the environment. Modelling plays an important role in this by helping our understanding of the environment and by forecasting likely impacts. In recent years moves have been made to link models to Geographical Information Systems to provide a means of analysing changes over an area as well as over time. GIS and Environmental Modeling explores the progress made to date in integrating these two software systems. Approaches to the subject are made from theoretical, technical as well as data stand points. The existing capabilities of current systems are described along with important issues of data availability, accuracy and error. Various case studies illustrate this and highlight the common concepts and issues that exist between researchers in different environmental fields. The future needs and prospects for integrating GIS and environmental models are also explored with developments in both data handling and modelling discussed. The book brings together the knowledge and experience of over 100 researchers from academic, commercial and government backgrounds who work in a wide range of disciplines. The themes followed in the text provide a fund of knowledge and guidance for those involved in environmental modelling and GIS. The book is easily accessible for readers with a basic GIS knowledge and the ideas and results of the research are clearly illustrated with both colour and black and white graphics.

summary	Computerization has been a positive factor in the evolution of both kinds of analysis with respect to cost, availability and efficiency. Knowledge-based systems offer an appropriate implementation environment for normative analysis which can be more reliable and economical than evaluation by human experts. Perhaps more significant is the potential of interactive computer simulation where designs can be examined intuitively in full detail and at the same time by quantitative models. The advantages of this coupling are evident in the achievements of scientific visualization. Another advantage of computational systems is that the analysis can be linked to the design representation, thereby adding feedback to the conventional visualization of designs in drawing and modeling systems. Such connections are essential for the development of design guidance systems capable of reflecting consequences of partial inadequacies or changes to other aspects in a transparent and meaningful network of design constraints. The possibilities of computer simulation also extend to issues inadequately covered by normative analysis and in particular to dynamic aspects of design such as human movement and circulation. The paper reports on a framework for addressing two related problems, (a) the simulation of fire escape from buildings and (b) the simulation of human movement on stairs. In both cases we propose that current evaluation techniques and the underlying design norms are too abstract to offer a measure of design success, as testified by the number of fatal accidents in fires and on stairs. In addition, fire escape and stair climbing are characterized by great variability with respect to both the form of the possible designs and the profiles of potential users. This suggests that testing prototypical forms by typical users and publishing the results as new, improved norms is not a realistic proposition for ensuring a global solution. Instead, we should test every design individually, within its own context. The development of an affordable, readily available system for the analysis and evaluation of aspects such as fire escape and stair safety can be based on the combination of the technologies of virtual reality and motion capture. Testing of a design by a number of test people in an immersion space provides not only intuitive evaluations by actual users but also quantitative data on the cognitive and proprioceptive behaviour of the test people. These data can be compiled into profiles of virtual humans for further testing of the same or related designs.
