title	The Economics of Building : A Practical Guide for the Design Professional
source	xvii, 209 p. : ill. New York: John Wiley & Sons, 1990. includes bibliography
summary	This book is both an introduction to economic principles and theories as they relate to building design decisions, and a practical reference guide on how to use economic principles when making decisions. It unites a variety of specialized topics relating to building economics, such as cost estimating, life-cycle costing, cost indexes, capital budgeting, decision analysis, and real estate feasibility analysis, developing them within the framework of an integrated approach to making building design and management decisions. This integrated approach is developed by adapting basic approaches of decision theory to economic evaluation. This book attempts to achieve a sensible balance between the need to simplify relatively complex economic and decision theory principles and practices without sacrificing the intellectual content of the material

title	What's in a representation, why do we care, and what does it mean? Examining evidence from psychology
source	Automation in Construction 8 (1) (1998) pp. 15-24
summary	This paper examines psychological evidence on the nature and role of representations in cognition. Both internal (mental) and external (physical or digital) representations are considered. It is discovered that both types of representation are deeply linked to thought processes. They are linked to learning, the ability to use existing knowledge, and problem solving strategies. The links between representations, thought processes, and behavior are so deep that even eye movements are partly governed by representations. Choice of representations can affect limited cognitive resources like attention and short-term memory by forcing a person to try to utilize poorly organized information or perform 'translations' from one representation to another. The implications of this evidence are discussed. Based on these findings, a set of guidelines are presented, for digital representations which minimize drain of cognitive resources. These guidelines describe what sorts of characteristics and behaviors a representation should exhibit, and what sorts of information it should contain in order to accommodate and facilitate design. Current attempts to implement such representations are discussed.

title	Binary Oppositions: Should Designers Learn to Think Differently in order to Better Utilize Digital Design Tools?
source	ACADIA Quarterly, vol. 19, no. 4, pp. 2-4
doi	https://doi.org/10.52842/conf.acadia.2000.002.2
summary	The development of information technology and its application to design disciplines has changed how buildings are described and even how they are built. Engineers, architects, contractors, and other parties often exchange files instead of paper drawings, and manufacturers can be sent numeric data to guide the fabrication of customized building components. The tools of the trade, even the things possible in the trade, are changing. This brings up the issue of how best to utilize this emerging technology. Should we mold this technology to fit the tasks and concepts we have in mind, or should we learn new ways of thinking about architecture and our role as architects? Do we need to get used to thinking in terms of RGB values, external file references, geometric transformations, and paper space vs. model space? In short, should designers learn to think differently in order to better utilize digital design tools?

title	Binary Oppositions: Will Computers Be Able to Design as well as Human Designers in the Foreseeable Future?
source	ACADIA Quarterly, vol. 19, no. 2, pp. 19-20
doi	https://doi.org/10.52842/conf.acadia.2000.019.2
summary	Research over the last few decades has suggested the possibility that computer-based systems may transcend their roles as media and tools for design, and actually adopt the role of designer. This prompted the topic for this debate: “Will computers be able to design as well as human designers in the foreseeable future?” Arguing to the affirmative is Ganapathy Mahalingam of North Dakota State University. I offer the argument to the negative. These arguments are presented below, so that you may weigh them and form your own opinions.

title	Toward Making the Language of CAAD Match the Language of Architecture: A Protean Elements Approach
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 93-100
doi	https://doi.org/10.52842/conf.ecaade.1998.093
summary	Both in education and in practice, architecture is experiencing a division between designers and "CAD specialists." One reason for the division may be the inherent division between design concepts and CAD concepts. In a very real sense, computer use and design utilize different languages. Becoming an expert in the "craft" of CAD means having to learn to recognize and manipulate a different set of conceptual elements than is used in design. The set of concepts we use affects our thought and behavior incredibly deeply, and translation from one set of concepts to another has significant cognitive cost. This paper discusses the mismatch between architectural and CAD concepts, and proposes protean elements as a solution to the problem. Protean elements are CAD system elements which correspond to architectural elements and have attributes appropriate for the elements they represent. They can be gradually refined in a top-down manner, without demands for certain pieces of missing data, or requirements for "correctness." The goal is to help CAD systems come closer to speaking the same language as architects. A test implementation of a system based on protean elements is currently underway, and aspects of this implementation are discussed.

title	Making Models Architectural: Protean Representations to Fit Architects’ Minds
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 354-365
doi	https://doi.org/10.52842/conf.acadia.1998.354
summary	A rich vocabulary has evolved for describing architecture. It serves not only as a means of communication, but also as an embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in terms of walls, rooms, roofs, arches, etc., we see in terms of them and think in terms of them, as well. Such concepts are integral to our ability to design. Typical CAD representations, however, are based on geometric/mathematical elements like points, lines, planes, and symbols. Even more experimental approaches like parametric shapes or procedural assemblies correspond poorly to architectural elements, and seldom lend themselves well to making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even between computer and studio faculty. Different ways of talking and thinking are involved. The concepts involved are often mutually exclusive. This paper discusses an attempt to address this conceptual mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to architectural concepts like “wall,” or “dome.” They each have parameters appropriate for the particular type of element they represent, and produce the polyhedra necessary for graphics based on these parameters. A system is being implemented to allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some elements hierarchically contain others, and some elements are essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element are discussed, including the underlying object-oriented structure, the relationship between elements and graphics, and functions associated with the objects. A scheme is explained whereby all parts of a design can be represented even when the design includes extremely unusual forms not conforming to predictable classes of elements. The necessary support framework is also discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained. The current status of the project, and intentions for future work are discussed. The project has been partially implemented, and the necessary framework to support the system is mostly complete.

title	Linking Analysis and Architectural Data: Why It's Harder than We Thought
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 230-243
doi	https://doi.org/10.52842/conf.acadia.2004.230
summary	This paper considers high-level, architecturally oriented representations, like Building Information Models (BIMs), and examines the difficulty of integrating analyses with such representations. Structural analysis is selected as a sample analysis domain, and is examined by integrating a structural analysis into the test implementation of a program that utilizes architecturally oriented elements. A fundamental problem is found to be that architecturally oriented elements are inappropriate for structural analysis. Methods for sequentially analyzing architectural elements are discussed, but are found to be inadequate. Accurate analysis requires analyzing the entire structure at once using a representation specific to structural analysis. A method for generating a structural representation based on the architectural representation is discussed, but the process is not simple. The process is complicated by the fact that architectural elements and structural elements do not correspond in a one-to-one or even a one-to-many manner. An accurate structural representation may even require semi-fictitious elements not corresponding to actual physical components. These findings are believed to be true for other analysis domains, as well.

summary	In the previous issue of the Quarterly, Dr. Ganapathy Mahalingam and I debated whether computers themselves would be able to design well in the foreseeable future. The topic for the current issue concerns computers aiding human designers. It is a separate goal from that considered in the previous issue, and it might be either easier or more difficult to achieve.

title	Mental Models
source	Cambridge, MA: Harvard University Press
summary	As psychological representations of real, hypothetical, or imaginary situations, mental models were first postulated by the Scottish psychologist Kenneth Craik (1943), who wrote that the mind constructs "small-scale models" of reality to anticipate events, to reason, and to underlie . The models are constructed in working memory as a result of perception, the comprehension of discourse, or imagination (see 1982; Johnson-Laird 1983). A crucial feature is that their structure corresponds to the structure of what they represent. Mental models are accordingly akin to architects' models of buildings and to chemists' models of complex molecules.

title	Integrated building simulation tool RIUSKA
source	Building Simulation, Prague, Czech Republic
summary	A new integrated simulation system for the building services design and facilities management purposes is being developed by Insinööritoimisto Olof Granlund Oy. The system covers the thermal simulation needs of the whole building life cycle from the preliminary design to renovations. The main components of the simulation system are a simulation database, user interfaces, a result module, a building geometry modeller and a calculation engine. The building geometry modeller generates a 3-D surface model of the building. The calculation engine of the first version is DOE 2.1E. The simulation database is linked to other design databases and design programs so that redundant input data is avoided.

title	Virtual Communication and IT in Architectural Education and Practice
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 116-121
summary	Research and innovation in the field of IT and communication facilities and technologies represents a new dimension, characteristic for the end of 20th and beginning of 21st century. Information technologies provide great opportunities in the process of architectural and urban design creation and spatial evaluation. They are very powerful tools for the architect, either in practice or still student, to express his thoughts, work, design. Information technologies also present strong means for communication in the process of generation of architectural and urban design. Main target in the educational activity of the Department of Computer Aided Architectural Design at the Faculty of Architecture is to train students in making the most efficient choices for software methods and technologies, which they use in their studio project works in architecture, landscape design, interior or industrial design. The aspects of teaching, research activity and own architectural practice creativity is in many way stressed.

title	The Quantum Matrix:A Three Dimensional Data Integration and Collaboration ToolFor Virtual Environments
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	If a picture is worth a thousand words, what if they could walk and talk? How would you like to bring a whole new dimension to your ideas; to use visualization to convey a sense of time and motion, to use imagery to give your ideas vividness; to use sound to give them voice and view them threedimensionally. The Matrix allows you to do all of this and much more. The Matrix resembles Rubik’s cube, but its purpose is to store, manage and access data of all types and to view them in three dimensions in virtual environments such as the CAVE and on your desktop. The current version can store, access and view almost anything that is in digital form, including:Text files Pictures Video Clips Sound Files Spreadsheets URL’s HTML pages Databases CAD drawings Gantt Charts Business Graphics VRML modelsExecutable Programs OLE (Object Link & Embedded) The Matrix is a three-dimensional multimedia and document management tool. The Matrix anticipates the convergence of electronic media into one consistent environment for analysis and representation. the Matrix uses VMRL and OpenGL technologies to allow the user to be immersed in their data as withCinerama, IMAX and Virtual Reality Environments. The Matrix allows the user to exercise their creativity by interactively placing and organizing their data three dimensionally and navigating through and viewingdata and documents in 3D (monocular and binocular – stereo). The Matrix user interface is simple to use. Employing the now familiar “drag and drop” method to manage data and documents. Items can be placed into the matrix grid at a user selected matrix cube location. Upon dropping a document on a cube it appears as a mapped image onto the surface. Navigating through the 3D Matrix-space is fun. All navigation uses real-time animation giving you instant feed back as to where you are. Data drilling is as simple as mouse click on a Matrix cube. Double clicking the on an object in the matrix activates that object. Data dreams was an image that preexisted the program by several years. The dream was to create a new way oforganizing and exploring data. The Qube image was created using Microstation by Bentley Systems, Inc. The figure was modeled using Poser by MetaCreations and composited using Adobe Photoshop.

summary	The goal of the presented research is to explore human-machine interaction and to study how Augmented Reality (AR) may be a potential tool to inform Architectural Rehabilitation and Conservation processes. Nowadays obtaining data to inform both marchitecture projects and real estate investments is a very bureaucratic process. City councils technicians suffers from the same diffi culties when are in fi eldwork to do inspections and lack a complete sort of information. This proposal considers that the use of mobile technologies as smart phones and tablets can empower these technicians to obtain building related data. The specifi c goal of the study aims to develop a data model and an interface that can be made available to professionals which allows an efficiently reply to the user’s needs as the system enables the gathering of updated information considering a particular building.

title	A Spatial Relational Reference Model (3RM)
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 85-91
summary	In this chapter we hope to provide the reader with an impression of the objective, framework and possibilities of 3RM in the construction industry. In Dutch, 3RM stands for 'Ruimtelijk Relationeel Referentie Model' (Spatial Relational Reference Model). The model could begin to be used as an information-bearer in the building industry within which the specific trade information for each of the building participants could be interrelated, including drafting symbolism, building costs, physical qualities and building regulations. In this way, the model can be used as a means to a more efficient running of the building process and enabling the integration of information, at project level, provided by various building participants. The project should be defined in the same way as is a typical architectural project, whereby the actual development as well as the project management is carried out by architects. For the time being, development is limited to integral use at the design stage, but it also offers sufficient expansion possibilities to be able to function as a new communications model throughout the complete building process. We shall first provide information as to the origin, the objective and the execution of the project. Thereafter, we shall attempt to state the theoretical information problem within the building industry and the solution to this offered through 3RM. Finally, we shall report upon the results of the first phase of the 3RM project.
