title	A "spelling" checker for architectural drawings: Grammatical and syntactic analysis in structured representations
doi	https://doi.org/10.52842/conf.caadria.2001.369
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 369-378
summary	CAAD representations for the early design stages have traditionally focused on aspects apparently relating to design creativity. These, however, may be unconnected to the control and analysis of design constraints that affect the further development of the design. The stability and reliability of control and analysis rely on what (despite the dangers of the linguistic analogy) we might call the grammatical and syntactic well-formedness of the representation. The paper reports on the control of grammar and syntax in a representation of spatial and building elements with respect to both the syntagmatic and the paradigmatic dimension.

title	Simulation and representation. Learning from airflow analyses in buildings
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 657-666
summary	The simulation of environmental aspects is a current priority in design research and practice. The availability of relatively efficient and reliable simulation systems and the emphasis on environmental aspects throughout a building’s lifecycle combine to stimulate exploration of aspects such as lighting and air quality by computational means. Nevertheless, a frequent complaint is that the addition of such simulations makes design information processing timeconsuming and cumbersome, thereby increasing uncertainty and indecision. Therefore, it is imperative that simulation is integrated in the strategies and tools normally used by the digitally-minded architect. In this respect a central issue is the relations between the simulation and the design representation used as connecting tissue for the whole design environment. Input of design information in the simulation means identification of relevant objects, aspects, parts and properties of these objects, as well as relationships between objects. The explicit description of objects such as spaces, doors and windows in the design representation allows for ready extraction of relevant information, including automatic recognition of relationships such as adjacency between a window and a space. The addition of information specific to the airflow analysis was resolved by the extension of the representation to cover front-end service components such as inlets and outlets and general properties (annotations) such as activities accommodated in a space and the primary choice of cooling and heating subsystems. The design representation is also the obvious target for the output of the simulation (feedback). Visualization of airflow in terms of the resulting voxels makes effortless and enjoyable viewing but merely allowing the visualization to coexist with the representation of spaces and building elements does not provide design guidance. One way of achieving that is by treating spaces not as integral entities but as containers of relevant surfaces. These surfaces determine the adaptive subdivision of the space and function as attractors for voxel clustering.

title	Grammatical and syntactic properties of CAAD representations for the early design stages
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	CAAD representations for the early design stages have traditionally focused on aspects apparently relating to design creativity, such as flexible, effortless and rich geometric modelling. However, modelling capabilities are generally unconnected to the control and analysis of design constraints that affect the further development of the design. These usually refer to functional and spatial aspects that are only implicit in a CAAD representation of design ‘solids’. Moreover, the stability and reliability of control and analysis rely on the grammatical and syntactic quality of the representation. In particular, (a) the grammatical well-formedness of spatial and building primitives, and (b) the syntactic completeness and unambiguity of spatial relations are essential prerequisites to any meaningful analysis of aspects such as fulfilment of programmatic requirements, indoor climate, lighting or human interaction with the built environment. The paper describes a dual spatial and building element representation implemented on top of a standard drawing system. The representation attempts to minimize input requirements, while at the same time providing feedback on the grammatical and syntactic quality of the design description.

title	Types and precedents in design guidance
doi	https://doi.org/10.52842/conf.ecaade.2003.653

summary	In recent years Dutch secondary education has been undergoing a fundamental change due to the introduction of new didactic approaches which relate strongly to ongoing social and technological developments. This affects existing school buildings, the majority of which is quite conventional in spatial terms and is characterized by limited flexibility and transformability. Consequently, most schools require extensive modifications in their spatial and building structure. The requirements underlying these modifications are not stable. Many schools have become interested in experimental ideas that may require inevitably further changes in the buildings. The paper considers the continuous transformation of Dutch school buildings with respect to their typology: by correlating new design briefs to building types rather than their instances we arrive at general guidelines that can be easily adapted to specific cases. To achieve this, the types are analysed with respect to geometry, topology and zoning. The results of the analysis describe the affordances of each type in terms of general flexibility, transformability and adaptability, as well as in relation to generic briefs. They also provide an explanation of the historical evolution of the types and the means for relating primary characteristics to local configurations, thereby allowing the accurate description of hybrid instances. The descriptions and analysis of buildings are organized into a polyhierarchical multilevel database that supports typological abstraction and offers several starting points (at various abstraction levels) for matching a new brief to an existing building. This enriches the development of the brief or a design solution with explicit, specific information derived from concrete precedents with known form, structure, behaviour and performance.

title	On the Correlation of Design and Computational Techniques in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1993.x.g6i
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Many studies employ analyses of human intelligence as justification or guideline for the development of machine intelligence. The main benefit brought on by such studies has been the improvement of our understanding of both human and machine intelligence. In teaching architecture with computers the same approach can make explicit design techniques architects use by means of equivalent or similar computational techniques. Explicitation of design techniques leads to a better understanding of architects' activities, as well as to which computer tools can offer automated support to these activities. In the curriculum of the Faculty of Architecture, Delft University of Technology, relations and correspondences between computational and design techniques form a major underlying theme in computer-aided design courses. The purposes of this theme are (i) comprehension of the computational structure of a computer design tool, and (ii) explanation of how such computational structures relate to architectural design. (correspondences between the computational principles of computer programs and design techniques are instrumental in defining the scope of each computer tool in architectural design while improving the students' understanding of architectural design as a cognitive process and thus promoting automation as a natural extension of established conventional practices. The paper outlines the correlation of computational and design techniques in the case of electronic spreadsheets. Spreadsheets are introduced through a thorough presentation of the various kinds and aspects of constraint propagation, their underlying computational principle. Numerical constraint propagation is explained by means of spreadsheet applications for simple numerical calculations. Symbolic constraint propagation is presented in the framework of machine perception. Both forms are then linked to architectural design through parametric design and the recognition of spaces in floor plans. Exercises linked to spreadsheets and constraint propagation include the parametric calculation of stairs and making parametric variations of a building on the basis of floor area calculations.

summary	Information systems increasingly appear as core elements of computer-aided architectural design environments. They provide the input and accommodate the output of automated and interactive procedures. The paper proposes the development of architectural information systems as an unobstrusive multimedia infrastructure in the background of specialized programs used for performing specific design t.asks. Background multimedia systems facilitate communication between specialized programs by means of their compound representations. These combine different types of information and provide an overview of the overall system and of the processes implemented in it.

title	Multilevel Analysis of Fire Escape Routes in a Virtual Environment
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 331-342
summary	The paper discusses the computer-aided analysis and evaluation of fire safety in relation to pedestrian circulation in buildings, i.e., fire escape routes. It describes an approach employing both detailed and abstract representations. The goals of the research include: (a) the development of a pyramidal structure that links design analyses at different levels of abstraction; (b) the evaluation of abstract, normative levels of the analysis (and though these of underlying legal and professional principles) using the results of detailed, accurate simulations; and (c) the development a reliable framework for testing human behaviour in fire hazard.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 245-266
summary	The first stage of an investigation into the quantification and computability of architectural aesthetics is reported. Issues considered include the function, sources and role of aesthetic analysis in architecture in the framework of a descriptive approach to architectural analysis and design. The main focus is on the applicability of the concept of figural goodness to architectural aesthetics and the derivation of a representation for architectural form suitable to this purpose.

title	Approaches to the Integration of CAAD Education in the Electronic Era: Two Value Systems
doi	https://doi.org/10.52842/conf.ecaade.1999.238
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 238-243
summary	In recent years the democratization of information and communication technologies (ICT) has become the greatest influence on the structure of CAAD education. While the content of the CAAD courses simply had to absorb the new technological possibilities, the structure of the courses and in particular their relationship to the rest of the curriculum has become the subject of speculation and experimentation. Integration of CAAD education in an architectural curriculum occurs either by (a) placing emphasis on designing in CAAD courses, or by (b) integrating computing in design courses. Both approaches respond to the democratization of ICT by making design computing widely available and acceptable. Further improvement is possible if the student becomes the carrier of integration. This is based on the long-term amplification of two value systems. The first refers to personal cognition: rather than rewarding a student with the teacher's approval, educational goals should be translated into individual skills and knowledge. The second system addresses the values of the peer group: such groups support learning by comparison to other individuals and emerging communal characteristics, either as a result of competition or for reasons of assimilation.

title	Recognition and Indexing of Architectural Features in Floor Plans on the Internet
doi	https://doi.org/10.52842/conf.caadria.2000.357
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 357-366
summary	The Internet promises a worldwide information system, capable of uniting different sources and types of original, up-to-date and directly usable information. Among the main components of this system are retrieval mechanisms characterized by high precision and recall, as well as by supportive relevance feedback. The textual versions of these retrieval mechanisms have been available for some time and have achieved a certain degree of efficiency and sophistication. Image retrieval lags behind, despite the recent advances in content-based retrieval. In architecture this is largely due to the lack of integration of domain knowledge and known formalisms. Indexing and retrieval of architectural floor plans can rely on existing generative systems such as shape grammars and rectangular arrangements. By reversing generative systems in purpose we derive compact descriptions that describe completely a floor plan and make explicit all relevant features rather than a small number of features. The main limitation of reversed generative systems is that they apply to specific classes of designs. Unification in indexing and retrieval can only take place at the level of basic primitives, i.e. spaces and building elements. In both vector and pixel images of architectural floor plans this can be achieved by a universal recognition system that identifies salient local features to produce a basic spatial representation.

title	On the Management of Visual Design Documentation

source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 124-130
summary	One of the most significant consequences of computerization in design practice is a spectacular increase in the amount and complexity of information produced for the specification, analysis and communication of design decisions and products. Computerization is intended to have a positive effect on such subjects but offers no builtin guarantees. The complexity, redundancy and amount of information that is generated on a variety of media has accentuated the problems of archiving, indexing and retrieving design documentation, either in the same project or in related ones. The shortcomings of visual information processing derive from a number of inherent problems: lack of integration in information carriers and kinds; organizational uncertainty, especially with respect to archiving and retrieval; superficial replication of analogue practices; limited understanding of information utility; chronic underestimates of automation potential coupled to overestimates of costs. A progressive improvement of design documentation should focus on: (1) the integration of information kinds and carriers in a single representation (in the direction of virtual prototyping); (2) correlation of information registration and processing with information utility; (3) structural rather than opportunistic or deterministic integration of utility requirements in design representations; (4) recognition of informatization and information management as a new specialization that complements existing roles in the design and management of the built environment

title	Group design evaluation
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 333-337
summary	Architectural visualization refers not only to the bulk of documents produced in the externalization of design representations but also to a major component of design communication and decision-taking. The paper focuses on the use of visualization in group design processes, i.e. processes typically involving the issues of common authorship, multi-actor design and intensive interaction between different aspects. It proposes that effective group design visualization requires hybrid environments that combine digital and analogue media in unobtrusive and efficient support structures. Registration of design information in group visualization refers primarily to two complementary dimensions: the syntagmatic (the sequence of actions that produce an image) and the paradigmatic (the collection of graphic primitives in the image). Recording syntagmatic information (i.e. who drew what and when) is essential for disentangling the usually dense results of group visualization and for distinguishing between actors, aspects and alternatives.

title	The continuity style in architectural dynamic visualization
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 468-472
summary	The term “continuity style” in cinema refers to a collection of cinematic conventions aiming at a realistic viewing experience without drawing attention to the elements of illusion used in the representation of 3D space on 2D film. The continuity style underlies the majority of narrative films produced to date and has had a significant influence on other genres, including documentaries. Despite the similarities in purpose, architectural filmmaking owes little to the cumulative knowledge of filmmaking encapsulated in the continuity style. While narrative films focus on the viewing experience, architectural animation tends to be dominated by integral 3D building models. We propose that key elements of the continuity style could be applied to architectural dynamic visualization in order to enhance both lay perception of architectural space and professional analysis of design intentions. These elements refer to four primary areas of architectural dynamic visualization: narrative, camera use, lighting and model structure.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 152-159
summary	Applications of mobile information technologies in architecture and building require a high degree of contextual awareness not only for localization but also for distinguishing between different types of information (relevant, redundant, stable etc.). This awareness refers to the physical context of a device, as well as to the social dynamics of the situation (including interaction with shared information). Architectural knowledge and in particular design representations support the development of contextual awareness but there are significant differences between these representations and the use of information they convey in mobile applications.

summary	The paper presents an overview of mechanisms underlying architectural perception and recognition. These include both general perceptual principles and specific domain constraints. The former determine the objective identification of elements and relationships in any visual scene, while the latter make architectural styles recognizable even to perceivers without extensive acquaintance with architecture. This is because many of the architectural constraints underlying a style have a firm foundation in general principles.

title	Fuzzy Modelling for Early Architectural Design
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 589-610
summary	Fuzzy modelling is simultaneously an extension of existing modelling approaches and a negation of one of their main aspects, the crispness of their definition. As a digital equivalent of analogue sketching it allows designers to register and manipulate imprecise and uncertain information. In the framework of design representations fuzzy modelling supports the development of conceptual design models characterized by flexible definition and interaction. The main advantages of such models are fluency, abstraction and continuity, at a level similar to that of analogue techniques. In addition to that they offer the possibility of local autonomy, i.e. segmentation of a representation into self-regulating and cooperating components. Three alternative forms of fuzzy modelling are proposed: (1) Canonical objects with tolerances, (2) objects described by minimal and maximal values, and (3) point sets comprising discrete, autonomous particles that describe the object by their spatial or structural relationships.

summary	Visual representations play an important role in mobile architectural guides, especially with respect to the identification of buildings, i.e. matching internal representations to external ones (the documentation in the guide) and the perceived scene. By restructuring this documentation into networks of significant architectural entities and features a guide is enriched with flexible, economical means for supporting building identification under the typically variable conditions architectural travelers have to endure.

source	International Journal of Architectural Computing vol. 8 - no. 2, 223-231
summary	Among the founding fathers of architectural computing, the late W.J. Mitchell was arguably the one who managed to capture the imagination of the younger generations through overviews and insights that described the backgrounds and scope of the area in a way that was suitable for novices as well as people outside the area. Calling such overviews successful popularization is only part of the truth. More importantly, they formulate a coherent and comprehensive approach that allowed Mitchell to move between eras and contexts without loosing focus or sacrificing fundamental priorities. It is an approach that remains valid and usable, a source of inspiration and understanding for future generations in the area.

title	Briefing and Building Information Modelling: Potential for integration
source	International Journal of Architectural Computing vol. 15 - no. 2, 120-133
summary	The article brings together the subjects of briefing and Building Information Modelling. It considers the brief as information source for Building Information Modelling and Building Information Modelling as an environment for automating brief- related analysis and guidance. The approach is characterized by feedforward and feedback, incorporation of constraints from the brief in Building Information Modelling, connection of briefing goals to performance analysis and correlation of requirements in the brief to Building Information Modelling object properties and relations. To test the approach, 10 briefs are parsed into goals, constraints and requirements, which are then considered for integration in Building Information Modelling. As the majority of these items can become part of a model and subject to automated analyses, integration of briefing in Building Information Modelling is proposed as a viable option that can improve design and briefing performance but also signals significant changes to briefing.
