summary	In this paper we examine the potential of combining 2D shape packing algorithms and evolutionary methods in the design process. We investigate the ways such algorithms can be used in architectural design and how they may influence it. In the first part of this paper we introduce the theoretical framework of packing algorithms and genetic algorithms as well as the traditional design process and the nature of design problems. In the second part of the paper we introduce a software prototype that tests these algorithms in two contexts: the preliminary design of a shading façade pattern and the design of commercial housing layouts. The aim for both experiments was to generate optimal configurations based on user-defined criteria without resorting to exhaustive search. Several lessons were learned that point to the potential of evolutionary methods in architecture as well as the limitations of such methods. We conclude the paper with recommendations for further developing this research project.

title	Automatic Floorplan Design Using PIAF
source	August, 1988. 36 p. : ill. tables
summary	This paper presents PIAF (a Package for Intelligent and Algorithmic Floorplanning), developed at Sydney University Electrical Engineering (SUEE) for use in custom integrated circuit design. Floorplanning plays a crucial role in the design of custom integrated circuits. When design is approached in a top-down fashion, the function to be implemented on silicon is first decomposed in a conceptual phase into a Functional Block Diagram (FBD). This FBD has a 'blocks and buses' structure where blocks represent sub- functions and buses represent the interconnections that carry data and other information between blocks. The decomposition of the function into sub-functions is hierarchical and aims at reducing the complexity of the design problem. When the FBD is known, the floorplanning process may be performed. When this task is performed manually, the designer searches for a relative placement of the blocks and for an area and shape for each block to minimize the overall chip layout area while at the same time meeting design constraints such as design tool limitations, interconnection characteristics and technological design rules. PIAF is a knowledge-based system (KBS) that has been developed at SUEE during the last four years. It relies on a strategy that partitions the floorplanning task in a way that allows efficient use of heuristics and specialized design knowledge in the generation and pruning of the solution space. This paper presents the operation of PIAF and discusses several implementation issues including; KBS structure, knowledge representation, knowledge acquisition, current context memory design, design quality factors and explanation facility. This paper uses a running example to present the operation of each PIAF's KBS-based solving phases

title	VISTA VERSA – Critical Considerations on the Evolvement of Designerly Attitudes, Instruments and Networks in Design Driven Studies
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	Keynote Paper - We are all involved in design.Besides being the (sub)conscious recipients of all sorts of design driven activities, we are professionally concerned with products of design and acts of designing, either as practitioners or as academics, in some cases as both… As someone who was trained as a designer, drifted into design teaching and presently attempts to combine composition research with design practice, I feel there is a need to bridge the cultural gap between design and design research. I intend to put forward the case for more designerly approaches in the study of design. In this context I would like to discuss perspectives for design driven studies by considering the following ensemble of aspects:- the matter of shifting attitudes to design in a scientific context; - the necessity of expanding the scope of instruments of design in relation to methods and insights. - the furthering of opportunities for networks aimed at bringing out and communicating findings concerning different aspects of design.It is on the topic of interaction, between the targeted creativity of designing on the one hand and the open minded search for relevant knowledge, insights and applications on the other, that I would like to dwell. Furthermore, I hope to provoke some thoughts – and hopefully responses – concerning the roles of computer based applications in such studies. What kinds of impulses have computer technologies offered, should they perhaps have offered and indeed might they still be able to offer in this field? I would like to by take a critical look back and try to turn things around, towards a possible view forward…

title	Fabricating Sustainable Concrete Elements: A Physical Instantiation of the Marching Cubes Algorithm
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 239-247
doi	https://doi.org/10.52842/conf.acadia.2012.239
summary	This paper explores how an algorithm designed to represent form can be made physical, and how this physical instantiation can be made to respond to a set of design imperatives. Specifically, the paper demonstrates how Marching Cubes (Lorensen and Cline 1987), an algorithm that extracts a polygonal mesh from a scalar field, can be used to initiate the design for a system of modular concrete armature elements that permit a large degree of variability using a small number of discrete parts. The design of these elements was developed in response to a close examination of Frank Lloyd Wright's Usonian Automatic system, an architecturally pertinent historical precedent. The fabricated results positively satisfy contemporary design criteria, including maximal formal freedom, optimal environmental performance, and minimal life-cycle costs.

title	Using Formal Specifications in the Design of a Human-Computer Interface
source	Communications of the ACM April, 1983. vol. 26: pp. 259-264 : diagrams. includes bibliography.
summary	Formal specification techniques are valuable in software development because they permit a designer to describe the external behavior of a system precisely without specifying its internal implementation. Although formal specifications have been applied to many areas of software systems, they have not been widely used for specifying user interfaces. In the Military Message System project at the Naval Research Laboratory, the user interfaces as well as the other components of a family of message systems are specified formally, and prototypes are then implemented from the specifications. This paper illustrates the specification of the user interface module for the family of message systems. It then surveys specification techniques that can be applied to human-computer interfaces and divides the techniques into two categories: those based on state transition diagrams and those based on BNF. Examples of both types of specifications are given. Specification notations based on state transition diagrams are preferable to those based on BNF because the former capture the surface structure of the user interface more perspicuously. In either notation, high-level abstraction for describing the semantics of the user interface is needed, and an application-specific one is used here

title	A grammar-based system for the participatory design of urban structures [A grammar-based system for the participatory design of urban structures ]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	We propose a three-step participatory design cycle for the early urban design phase that can be integrated into the digital design chain. Step one involves a visualization method that is implemented as an interactive card-based interview technique for the collaborative requirement specification of urban designs. In step two these specifications are a) translated into simplified GIS data and then b) implemented into a grammar-based system together with the corresponding design regulations. The final outcome is a generative and iterative urban model, which includes buildings, building blocks, transportation networks and open spaces that visually communicates spatial impacts of urban design proposals.

title	The CAD Design Studio: 3D modeling as a fundamental design skill
source	McGraw-Hill, New York
summary	Until now, books on CAD aimed at architects have addressed the use of computer-aided design and drafting as a recording tool, a faster means of producing and storing finished working drawings-and not as an adjunctive creative tool for the design process. Without being software specific, this book will guide the professional and student architect and graphics designer in how to use the computer as an electronic modelling tool, exploring graphic and geometric forms and systems with the freedom and speed of the computer. The reader will be led through a progression of design exercises and design problems, learning how to come up with multiple solutions to a given program. Beautifully illustrated throughout, including 10 four-color CAD drawings!

title	Capturing the Infinite: Bottom up CAD - CAM Technology for Regenerative Development
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.b0l
summary	In most design practices there is a division between the generation of information to describe buildings and the production of information to construct them. Today architects are in charge of the design of the building (aesthetics) while the contractor is accountable for the means of construction (tectonics). The advent of digital technologies within the field of architecture however has begun to cause and will continue to cause fundamental changes within the AEC industry. The Paper describes a possible scenario where a Bottom – Up, part to whole approach to architecture can be adopted using the freedom afforded by Parametric Design within the CAD-CAM environment. This approach is explored through the design of a smart block in concrete that is integrated into a wall system.

title	Information management in creative engineering design and capabilities of database transactions
source	Automation in Construction 7 (1) (1997) pp. 55-69
summary	This paper examines the information management requirements and sets forth the general criteria for collaboration and concurrency control in creative engineering design. Our work attempts to recognize the full range of concurrency, collaboration and complex transactions structure now practiced in manual and semi-automated design and the range of capabilities needed as the demands for enhanced but flexible electronic information management unfolds.The objective of this paper is to identify new issues that may advance the use of databases to support creative engineering design. We start with a generalized description of the structure of design tasks and how information management in design is dealt with today. After this review, we identify extensions to current information management capabilities that have been realized and/or proposed to support/augment what designers can do now.Given this capability-based starting point, we review existing database and information management capabilities, as presented in the literature. In the review, we identify the gaps between current concurrency and collaboration technology and what is needed or would be desirable. Our objective is to assess current research and to identify new issues that may advance the use of databases to support creative engineering design.

title	The Chair Back Experiment: Hierarchical Temporal Memory and the Evolution of Artificial Intelligence in Architecture
source	International Journal of Architectural Computing vol. 8 - no. 2, 151-164
summary	Computational synthesis tools that automatically generate solutions to design problems are not widely used in architectural practice despite many years of research. This deficiency can be attributed, in part, to the difficulty of constructing robust building specific databases. New advances in artificial intelligence such as Hierarchical Temporal Memory (HTM) have the potential to make the construction of these databases more realistic in the near future. Based on an emerging theory of human neurological function, HTMs excel at ambiguous pattern recognition. This paper includes a first experiment using HTMs for learning and recognizing patterns in the form of visual style characteristics in three distinct chair back types. Results from the experiment indicate that HTMs develop a similar storage of quality to humans and are therefore a promising option for capturing multi-modal information in future design automation efforts.

title	AND WOULD COMPUTER SAVE THE MAGIC PLACE? A BOJARY STORY
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	Each city has its own magic, the spirit of the place. Not always are these ‘magic’ places commonly known. There are cities, however, for which such places are their pride and fame. Is there anybody who would not associate the Golden Street with Prague, or the Spanish Stairs with Rome? In Bialystok the magic quality is attributed to the district of Bojary.Currently Bojary is one of the districts of Bialystok. The town was first created as such in the 18th century as a result of merging of two villages: Bojary and Skorupy, church grounds and Kolonia Lowiecka known as Krolikarnia. Only Bojary has retained the old communication plan of the former village and characteristic type of wooden structure from the 19th and the first half of the 20th century.

doi	https://doi.org/10.52842/conf.caadria.2004.845
summary	Cyberspace is more malleable than a physical environment, so it can afford much wider range of responsiveness. By applying the concept of place-making, we are experimenting virtual environments which are responsive to their users’ context-specific needs. Since objects are essential components that anchor the users’ various activities, having interactive objects in a 3D virtual environment is a major design concern for developing a dynamic and experience-rich virtual environment. We propose a layered agent model for intelligent behavior control of 3D objects, based on constraint solving process.

summary	The space layout planning problem belongs to the class of NP-hard problems with a wide range of practical applications. Many algorithms have been developed in the past, however recently evolutionary techniques have emerged as an alternative approach to their solution. In this paper, a genetic programming approach, one variation of evolutionary computation, is discussed. A representation of the space layout planning problem suitable for genetic programming is presented along with some implementation details and results.

title	Parametric Design and Analysis of Dynamic Louver for Optimized Daylighting in High-Rise Office Buildings
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 493–502
doi	https://doi.org/10.52842/conf.caadria.2023.1.493
summary	This paper presents an innovative approach to optimize daylighting in high-rise office buildings, through parametric analysis of dynamic shading system designs. This study concentrates on a kinetic shading angle optimization plot to determine the optimum angles of the dynamic horizontal louver shading systems at specific times with integrated operationalization equations and parametric performance simulations. Solar irradiance and daylighting were considered as performance metrics in this research, which investigated the integration process using the operationalization method in order to find an optimal rotational angle of dynamic horizontal louver shading systems at the specified time. In this study, dynamic horizontal louver shading systems were positioned in different orientations (Southeast and Southwest) to evaluate the effect of the shading’s tilt angles on daylighting. To quantify the daylight quality, maximum and average illuminance were obtained from the raw illuminance on the work plane. At the end, the outcomes of the analyses as well as the optimized angle of the dynamic louver shading were compared to a base case with no shading, and the results prove that dynamic louver with the support of an operationalization method to find optimum angle and testing with parametric performance software leads to optimizing the daylighting performance, enhancing it by approximately 14%.

title	Creating Immersive Virtual Landscapes A User-Centered Approach to Enhance Depth Perception in Head-Mounted Displays
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 149–158
doi	https://doi.org/10.52842/conf.ecaade.2023.1.149
summary	This paper investigates the effects of color, luminance, and transparency as depth distortion cues in Virtual Reality (VR) Head-mounted Displays (HMD). The aim is to tackle more in-depth immersion: focusing on interaction accuracy with transparent objects in HMDs. Due to the illumination and absence of texture, transparent objects are mainly displayed with colors. Recently, studies on transparent hands and objects have elucidated potential approaches regarding interaction with transparent elements. However, findings have not considered color and luminance as depth distortion cues for interacting in virtual landscapes. This paper used the forced-choice pairwise comparison experiment method and evaluated data based on the Kendall coefficient of agreement and consistency. Reverse effects of transparency on color and luminance are discovered. Cool colors are perceived nearer than warm colors in 90% transparency. Dark colors are sensed closer than bright colors in high transparency levels. These results reject the classical effects of color and luminance within VR HMDs. These findings help VR design tool developers who emphasize a particular use of depth cues. Designers can utilize the studied effects of color and luminance on transparent objects as an advantage in designing more interactive and immersive virtual landscapes.
