title	Cognitive Biases - The case of tropical architecture
source	Delft University of Technology
summary	This dissertation investigates, i) How cognitive biases (or illusions) may lead to errors in design thinking, ii) Why architects use architectural precedents as heuristics despite such possible errors, and iii) Develops a design tool that can overcome this type of errors through the introduction of a rebuttal mechanism. The mechanism controls biases and improves accuracy in architectural thinking. // The research method applied is interdisciplinary. It employs knowledge from cognitive science, environmental engineering, and architectural theory. The case study approach is also used. The investigation is made in the case of tropical architecture. The investigation of architectural biases draws from work by A. Tversky and D. Kahneman in 1982 on “Heuristics and biases”. According to Tversky and Kahneman, the use of heuristics of representativeness (based on similarity) and availability (based on ease of recall and imaginability) for judgement of probability can result in cognitive biases of illusions of validity and biases due to imaginability respectively. This theory can be used analogically to understand how errors arise in the judgement of environmental behaviour anticipated from various spatial configurations, leading to designs with dysfunctional performances when built. Incomplete information, limited time, and human mental resources make design thinking in practice difficult and impossible to solve. It is not possible to analyse all possible alternative solutions, multiple contingencies, and multiple conflicting demands, as doing so will lead to combinatorial explosion. One of the ways to cope with the difficult design problem is to use precedents as heuristic devices, as shortcuts in design thinking, and at the risk of errors. This is done with analogical, pre-parametric, and qualitative means of thinking, without quantitative calculations. Heuristics can be efficient and reasonably effective, but may not always be good enough or even correct, because they can have associated cognitive biases that lead to errors. Several debiasing strategies are discussed, and one possibility is to introduce a rebuttal mechanism to refocus the designer’s thinking on the negative and opposite outcomes in his judgements, in order to debias these illusions. The research is carried out within the framework of design theory developed by the Design Knowledge System Research Centre, TUDelft. This strategy is tested with an experiment. The results show that the introduction of a rebuttal mechanism can debias and improve design judgements substantially in environmental control. The tool developed has possible applications in design practice and education, and in particular, in the designing of sustainable environments.

title	A Generalization of Algebraic Surface Drawing
source	ACM Transaction on Graphics, vol. 1, no. 3, pp. 235-256, 1982
summary	The technology of creating realistic and visually interesting images of three- dimensional shapes is advancing on many fronts. One such front is the develop- ment of algorithms for drawing curved surfaces directly from their mathematical definitions rather than by dividing them into large numbers of polygons. Two classes of surfaces which have received attention are the quadric and the bivariate parametric surfaces. Bivariate parametric surfaces are generated by three func- tions of two variables (most popularly polynomials), as the variables take on different values. Algorithms dealing with such surfaces are due to Catmull; Lane, Carpenter, Whitted and Blinn; and Clark.

summary	The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

title	On Deep Disjunctive Cutting Planes for Set Partitioning : A Computationally Oriented Research.
source	Pittsburgh: Design Research Center, CMU [DRC-70-11-82], 10 p.
summary	Several mathematical programming problems can be formulated as Disjunctive Programming Problems. This approach offers a powerful procedure for the generation of new and strong cutting planes with desirable properties. For general integer programs, the traditional cutting plane methodologies proved less efficient than enumerative techniques. However, for certain classes of problems, such as set partitioning, cutting planes are known to be efficient. Since the disjunctive cuts are strong, they can be expected to perform better. This paper reports on computational results with disjunctive B(.) cuts for the set partitioning problem, evaluated in terms of computer resources and other independent measures in solving specific randomly generated test problems under controlled conditions.

title	Adaptive Finite Element Mesh Generation Using the Delaunay Algorithm
source	3 p. : ill. Pittsburgh: Design Research Center, CMU, December, 1982
summary	Includes bibliography. A two-dimensional generator is described which automatically creates optimal finite element meshes using the Delaunay triangulation algorithm. The mesh generator is adaptive in the sense that elements containing the largest normalized errors are automatically refined, providing meshes with a uniform error density. The system runs on a PERQ computer made by Three Rivers Computer Company. It is menu oriented and utilizes multiple command and display windows to create and edit the object description interactively. Mesh generation from the object data base is automatic, although it may be modified interactively by the user if desired. Application of the mesh generator to electric machine design and to magnetic bubble simulation shows it to be one of the most powerful and easy to use systems yet devised

title	Logic Programming as a Representation of Knowledge
source	IEEE Computer. IEEE Computer Society, October, 1983. vol. 16: pp. 106-110 : ill. includes bibliography
summary	Logic has traditionally provided a firm conceptual framework for representing knowledge. As it can formally deal with the notion of logical consequence, the introduction of Prolog has made it possible to represent knowledge in terms of logic and also to expect appropriate inferences to be drawn from it automatically. This article illustrates and explores these ideas with respect to two central representational issues: problem solving knowledge and database knowledge. The technical aspects of both subjects have been covered elsewhere (Kowalski, R. Logic for problem solving, North- Holland pub. 1979 ; Dahl, V. on database system development through logic ACM Trans.vol.7/no.3/Mar.1982 pp.102). This explanation uses simple, nontechnical terms

title	Development of interior finishing unit assembly system with robot: WASCOR IV research project report
source	Automation in Construction 5 (1) (1996) pp. 31-38
summary	The WASCOR (WASeda Construction Robot) research project was organized in 1982 by Waseda University, Tokyo, Japan, aiming at automatizing building construction with a robot. This project is collaborated by nine general contractors and a construction machinery manufacturer. The WASCOR research project has been divided into four phases with the development of the study and called WASCOR I, II, III, and IV respectively. WASCOR I, II, and III finished during the time from 1982 to 1992 in a row with having 3-4 years for each phase, and WASCOR IV has been continued since 1993. WASCOR IV has been working on a automatized building interior finishing system. This system consists of following three parts. (1) Development of building system and construction method for automated interior finishing system. (2) Design of hardware system applied to automated interior finishing system. (3) Design of information management system in automated construction. As the research project has been developing, this paper describes the interim report of (1) Development of building system and construction method for automated interior finishing system, and (2) Design of hardware system applied to automated interior finishing system.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	The Impact of CAD On Architectural Design Education in the United States

source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 348-355
summary	Computer-Aided Design (CAD) began to appear in schools of architecture in the United States over 15 years ago. By 1982, over 50% of all accredited schools of architecture in North America included some form of CAD in their curricula. This number has continued to steadily increase. For the most part, the use of CAD has been restricted to the few individuals working on special "CAD projects" and to the researchers developing CAD products. The reasons for this limitation have included the low availability, difficulty of use, restricted access and high cost of the CAD systems, as well as limited faculty and administrative support. Recently, however, partly due to the introduction of micro- computer CAD software, and partly due to the growing awareness of the importance of CAD in architectural education and practice, some schools have begun to introduce CAD as part of the general design curriculum.

title	An Integrative Approach to Computer-Aided Design Education in Architecture
source	February, 1985. [17] p. : [8] p. of ill
summary	With the advent of CAD, schools of architecture are now obliged to prepare their graduates for using the emerging new design tools and methods in architectural practices of the future. In addition to this educational obligation, schools of architecture (possibly in partnership with practicing firms) are also the most appropriate agents for pursuing research in CAD that will lead to the development of better CAD software for use by the profession as a whole. To meet these two rather different obligations, two kinds of CAD education curricula are required: one which prepares tool- users, and another that prepares tool-builders. The first educates students about the use of CAD tools for the design of buildings, whereas the second educates them about the design of CAD tools themselves. The School of Architecture and Planning in SUNY at Buffalo has recognized these two obligations, and in Fall 1982 began to meet them by planning and implementing an integrated CAD environment. This environment now consists of 3 components: a tool-building sequence of courses, an advanced research program, and a general tool-users architectural curriculum. Students in the tool-building course sequence learn the principles of CAD and may, upon graduation, become researchers and the managers of CAD systems in practicing offices. While in school they form a pool of research assistants who may be employed in the research component of the CAD environment, thereby facilitating the design and development of advanced CAD tools. The research component, through its various projects, develops and provides state of the art tools to be used by practitioners as well as by students in the school, in such courses as architectural studio, environmental controls, performance programming, and basic design courses. Students in these courses who use the tools developed by the research group constitute the tool-users component of the CAD environment. While they are being educated in the methods they will be using throughout their professional careers, they also act as a 'real-world' laboratory for testing the software and thereby provide feedback to the research component. The School of Architecture and Planning in SUNY at Buffalo has been the first school to incorporate such a comprehensive CAD environment in its curriculum, thereby successfully fulfilling its obligation to train students in the innovative methods of design that will be used in architectural practices of the future, and at the same time making a significant contribution to the profession of architecture as a whole. This paper describes the methodology and illustrates the history of the CAD environment's implementation in the School

title	Determining the Spatial Containment of a Point in General Polyhedra
source	Computer graphics and Image Processing. 1982. vol. 19: pp. 303-334 : ill. includes bibliography. See also criticism and improvements in Orlowski, Marian
summary	Determining the inclusion of a point in volume-enclosing polyhedra (shapes) in 3D space is, in principle, the extension of the well-known problem of determining the inclusion of a point in a polygon in 2D space. However, the extra degree of freedom makes 3D point-polyhedron containment analysis much more difficult to solve than the 2D point polygon problem, mainly because of the nonsequential ordering of the shape elements, which requires global shape data to be applied for resolving special cases. Two general O(n) algorithms for solving the problem by reducing the 3D case into the solvable 2D case are presented. The first algorithm, denoted 'the projection method,' is applicable to any planar- faced polyhedron, reducing the dimensionality by employing parallel projection to generate planar images of the shape faces, together with an image of the point being tested for inclusion. The containment relationship of these images is used to increment a global parity-counter when appropriate, representing an abstraction for counting the intersections between the surface of the shape and a halfline extending from the point to infinity. An 'inside' relationship is established when the parity-count is odd. Special cases (coincidence of the halfline with edges or vertices of the shape) are resolved by eliminating the coincidental elements and re-projecting the merged faces. The second algorithm, denoted 'the intersection method,' is applicable to any well- formed shape, including curved-surfaced ones. It reduces the dimensionality by intersecting the polygonal trace of the shape surface at the plane of intersection, which is tested for containing the trace of the point in the plane, directly establishing the overall 3D containment relationship. A particular O(n) implementation of the 2D point-in-polygon inclusion algorithm, which is used for solving the problem once reduced in dimensionality, is also presented. The presentation is complemented by discussions of the problems associated with point-polyhedron relationship determination in general, and comparative analysis of the two particular algorithms presented

title	The Concept of a Meta-Font
source	Visible Language. Winter, 1982. vol. XVI: pp. 3-27 : ill. includes bibliography
summary	A single drawing of a single letter reveals only a small part of what was in the designer's mind when that letter was drawn. But when precise instructions are given about how to make such a drawing, the intelligence of that letter can be captured in a way that permits us to obtain an infinite variety of related letters from the same specification. Instead of merely describing a single letter, such instructions explain how that letter would change its shape if other parameters of the design were changed. Thus an entire font of letters and other symbols can be specified so that each character adapts itself to varying conditions in an appropriate way. Initial experiments with a precise language for pen motions suggest strongly that the font designer of the future should not simply design isolated alphabets; the challenge will be to explain exactly how each design should adapt itself gracefully to a wide range of changes in the specification. This paper gives examples of a meta-font and explains the changeable parameters in its design

title	Development of a computerized handbook of architectural plans
source	Delft University of Technology
summary	The dissertation investigates an approach to the development of visual / spatial computer representations for architectural purposes through the development of the computerized handbook of architectural plans (chap), a knowledge-based computer system capable of recognizing the metric properties of architectural plans. This investigation can be summarized as an introduction of computer vision to the computerization of architectural representations: chap represents an attempt to automate recognition of the most essential among conventional architectural drawings, floor plans. The system accepts as input digitized images of architectural plans and recognizes their spatial primitives (locations) and their spatial articulation on a variety of abstraction levels. The final output of chap is a description of the plan in terms of the grouping formations detected in its spatial articulation. The overall structure of the description is based on an analysis of its conformity to the formal rules of its “stylistic” context (which in the initial version of chap is classical architecture). Chapter 1 suggests that the poor performance of computerized architectural drawing and design systems is among others evidence of the necessity to computerize visual / spatial architectural representations. A recognition system such as chap offers comprehensive means for the investigation of a methodology for the development and use of such representations. Chapter 2 describes a fundamental task of chap: recognition of the position and shape of locations, the atomic parts of the description of an architectural plan in chap. This operation represents the final and most significant part of the first stage in processing an image input in machine environment. Chapter 3 moves to the next significant problem, recognition of the spatial arrangement of locations in an architectural plan, that is, recognition of grouping relationships that determine the subdivision of a plan into parts. In the absence of systematic and exhaustive typologic studies of classical architecture that would allow us to define a repertory of the location group types possible in classical architectural plans, Chapter 3 follows a bottom-up approach based on grouping relationships derived from elementary architectural knowledge and formalized with assistance from Gestalt theory and its antecedents. The grouping process described in Chapter 3 corresponds both in purpose and in structure to the derivation of a description of an image in computer vision [Marr 1982]. Chapter 4 investigates the well-formedness of the description of a classical architectural plan in an analytical manner: each relevant level (or sublevel) of the classical canon according to Tzonis & Lefaivre [1986] is transformed into a single group of criteria of well-formedness which is investigated independently. The hierarchical structure of the classical canon determines the coordination of these criteria into a sequence of cognitive filters which progressively analyses the correspondence of the descriptions derived as in Chapter 3 to the constraints of the canon. The methodology and techniques presented in the dissertation are primarily considered with respect to chap, a specific recognition system. The resulting specification of chap gives a measure of the use of such a system within the context of a computerized collection of architectural precedents and also presents several extensions to other areas of architecture. Although these extensions are not considered as verifiable claims, Chapter 5 describes some of their implications, including on the role of architectural drawing in computerized design systems, on architectural typologies, and on the nature and structure of generative systems in architecture.
