title	Knowledge-based Stair Design

summary	The application of computer--based technique to support architectural design has often concentrated on matters of representation. Typically, this means computer-aided drafting, and less frequently, computer-aided modeling and visualization. The promise of new computer-based tools to support the process of design has thus far failed to produce any significant tool that has had a widespread impact on the architectural profession. Most developments remain in university based research labs where they are used as teaching instruments in CAD courses or less often in design studios. While there are many reasons for this lack of dissemination, including a reluctance on the part of the architectural profession itself, the primary obstacles deal with difficulties in explicating design knowledge, representing this knowledge in a manner that can be used for design, and providing an intuitive and effective user interface, allowing the designer to easily use the tool for its intended purpose. This study describes a system that has been developed to address a number of these issues. Based on research findings from the field of Artificial Intelligence which expounds on the need for multiple techniques to represent any complex area of knowledge, we have selected a particular approach that focuses on multiple techniques for design representation. We review this approach in depth by considering its many facets necessary when implementing a knowledge-based system. We then partially test the viability of this approach through a small case study, implementing a knowledge-based system for designing stairs. While this effort only deals with a small part of the total design process, it does explore a number of significant issues facing the development of computer-based design assistants, and suggests several techniques for addressing these concerns.

title	Towards a Genome for Zero Carbon Retrofit of UK Housing
doi	https://doi.org/10.52842/conf.ecaade.2023.2.197
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 2, Graz, 20-22 September 2023, pp. 197–206
summary	The United Kingdom has some of the worst insulated housing stock in Northern Europe. This is in part due to the age of housing in the UK, with over 90% being built before 1990 [McCrone 2017, Piddington 2020]. Moreover, 85% of current UK housing will still be in use in 2050 by which stage their Government are targeting Net Carbon Zero [Eyre 2019]. Domestic energy use accounts for around 25% of UK carbon emissions. The UK will need to retrofit 20 million dwellings in order to meet this target. If this delivery were evenly spread, it would equate to over 2,000 retrofit completions each day. Government-funded initiatives are stimulating the market, with upwards of 60,000 social housing retrofits planned for 2023, but it is clear that a system must be developed to enable the design and implementation of housing-stock improvement at a large scale.This paper charts the 20-year development of a digital approach to the design for low-carbon domestic retrofit by architects Constructive Thinking Studio Limited and thence documents the emergence of a collaborative approach to retrofit patterns on a National scale. The author has led the Research and Development stream of this practice, developing a Building Information Modelling methodology and integrated Energy Modelling techniques to optimise design for housing retrofit [Georgiadou 2019, Ben 2020], and then inform a growing palette of details and a database of validated solutions [Moorhouse 2013] that can grow and be used to predict options for future projects [D’Angelo 2022]. The data is augmented by monitoring energy and environmental performance, enabling a growing body of knowledge that can be aligned with existing big data to simulate the benefits of nationwide stock improvement. The paper outlines incremental case studies and collaborative methods pivotal in developing this work The proposed outcome of the work is a Retrofit Genome that is available at a national level.

summary	From 1959 to 1990, East St. Louis, Illinois deteriorated from an “All-American City” to a national symbol of urban blight. Located on the Mississippi River, the East St. Louis of today faces severe economic, social, and environmental problems. Nearly onequarter of the city’s work force is unemployed and about 40 percent of families are living below the poverty level. But East St. Louis was not always a distressed community. With strong ties to St. Louis and the surrounding region, East St. Louis onceflourished as the country’s second busiest railroad hub. Powerful economic and socio-political forces, as well as unfortunate historical circumstance, propelled the city into a downward spiral that drastically decreased the quality of life in East St. Louis. This paper presents the digital re-construction of the buildings and the analyses of the historical aspects of the housing construction and types in this area. Furthermore, it reports the survey and assessment of the quality of building stocks based on therevitalization plan that will provide some guidelines and suggestions for improvement, stability, and future needs.

doi	https://doi.org/10.52842/conf.acadia.1999

summary	Throughout known architectural history, representation, media and design have been recognized to have a close relationship. This relationship is inseparable; representation being a means for engaging in design thinking and making and this activity requiring media. Interpretations as to what exactly this relationship is or means have been subject to debate, disagreement and change along the ages. Whereas much has been said about the interactions between representation and design, little has been elaborated on the relationship between media and design. Perhaps, it is not until now, surrounded by all kinds of media at the turn of the millennium, as Johnson argues (1997), that we have enough context to be able to see and address the relationship between media and human activities with some degree of perspective.

summary	The application of new digital media provides a methodology for reconstructing and analyzing certain architectural elements from the past. In this paper, a research project is described to develop a prototype system to represent and manipulate information in urban settings. In general, our research is aimed at developing a prototype urban database model and Philadelphia is chosen as a case study. An emphasis is placed on identification, categorization and representation of information in a way that is useful for urban researchers for analysis.

summary	This research seeks to establish guidelines for a model to take advantage of AR as a tool in the process of developing new products in the formative stages of the design professional. For this it is necessary to determine in which part of the design process the use of these guidelines creates a greater impact in terms of time, money and results, later to define relationships between the guidelines found and generate schemes to visualize relationships, delivering a tool that can be used by students in their design processes.

title	Geometric Searching In Extended CSG Models : Application to Solid Modeling and Viewing
source	February, 1987. 30 p. : ill
summary	In this paper, the CSG representation scheme is augmented with the 'cartesian product.' The sweep method of generating solids is encompassed by this 'Extended CSG' formalism. The point inclusion problem encountered in the area of geometric searching in computational geometry is discussed in the context to solid models represented by 'extended CSG.' A simple algorithm to solve it that has a time complexity O(n), where n is the number of primitives, is presented. Allowing for preprocessing and extra storage, a second efficient algorithm, having a time complexity O(log n), is developed. The relevance of point inclusion problem in solid modelling techniques is indicated. An extended CSG based solid modeling method is proposed. A solution to the problem of hidden line removal, that uses the faster algorithm for the point inclusion problem, is also presented in the paper

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

title	Research on the design technique begun from "human activity" in an environmental design
doi	https://doi.org/10.52842/conf.caadria.2005.026
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 26-37
summary	In environmental design, an important point is that each person concerned deals with a specific aspect of a project, and it is important these people discuss with, arrive at consensus, and advance steadily. One general problem in this environmental initial design stage that should be mentioned is that of concentrating only on the act of building, "field and facility". That is, the human activity, such as use, maintenance management, etc. after construction, and building usage are seldom considered. The purpose of the research is to make sharing the image of "human activity" easy within a team, and the research proposes media which support this as part of a design technique which performs examination and proposal smoothly, and can examine "field and facility" continuously.

title	The Assembly and Fabrication of Double Curved Panel Structure Using Japanese wood Joints created by Desktop 3D Printers
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1245–1255
summary	This research presents a new direction for freeform structure assembly and fabrication through the collaboration of 3D printing technology and Japanese wood joining technology. Full-scale, self-build prototyping is demonstrated without glue or metal fittings. Rather than relying on digital fabrication machines to match the architectural scale, this study utilizes the Fused Filament Fabrication (FFF) with desktop 3D printers, which is the most widespread and inexpensive printing technology. By incorporating the perspectives of wood joinery and compact 3D printers, this study promotes a drastic change in 3D printed architectural production from a massive structure-oriented system to a module-oriented system. The project demonstrates how artisanal knowledge integrates with 3D printing architectural production by reconfiguring joint geometry, parametric modeling, fabrication, and assembly processes. We discuss our research process and final achievements, and we provide new ideas for architectural production using digital fabrication.

summary	Working on the margins of the discipline, traditionally untouchable, constitutes a substantial challenge for contemporary professional practice, as technological innovations can produce significant changes and benefits. Government founded social housing constitutes a relevant object to explore and explode, incorporating new methods of analysis rendered possible by new information and knowledge management digital technologies. Therefore, it is possible to produce an expanded field of knowledge, analyzing each case and bringing into play a large number of variables in order to offer socially responsible alternatives.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 231-244
summary	We present a physics-based generative design approach to interactive form-finding. While form as a product of dynamic simulation has been explored previously, individual projects have been developed as singleton solutions. By identifying categories of computational characteristics, we present a novel unified model that generalizes existing simulations through a constraint-based approach. The potential of interactive form finding simulation is explored through exemplary studies: a conceptual approach to a fixed form that acts as a visualization of interacting forces, and a constraint-based model of the fabrication logic for a panelization system are examined. Implications of constraint-based simulation on future directions are discussed.

source	J.A. Clarke, J.W. Mitchell, and R.C. Van de Perre (eds.), Proceedings, Building Simulation '91 IBPSA Conference, pp. 367-374
summary	We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process. We review and discuss current efforts in the US and Europe in the development of next-generation simulation tools and design integration techniques. In particular, we describe initiatives in object-oriented simulation environments (including the US Energy 'Kernel System, the Swedish Ida system, the UK Energy Kernel System, and the French ZOOM program.) and consider the relationship of these environments to recent R&D initiatives in design integration (the COMBINE project in Europe and the AEDOT project in the US).

summary	The advent of BIM in the AECO industry brings with it profound transformations in the design process. These changes are necessary to meet the requirements of the current project market and make the traditional design process into an integrated design process. Although the advantages obtained from this practice, new job functions and standardization of communication must be embraced to ensure its success. This work presents the conception of the integrated project in BIM with its practices related to the PDP and identifies the evolution of the norms of aid to the realization of projects in BIM in Brazil.

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.379-387
summary	The Attractive City Generator is an interactive installation with which users can create or rearrange virtual cities by placing and moving physical objects. Through the set of simple inputs that the users provide and which represent city areas, landscapes or landmarks, the ACG is capable of creating complex and growing cities. In addition, a plethora of factual feedback on these cities is calculated. Becoming physically involved enhances the learningprocess and increases the user’s interest. The users are drawn to the colourful and simple interface. Due to the practical feedback that the city returns, the users can feel more attached to the city they have created. A dynamic dialogue is formed between the city and its creators, that involves the wishes of the users versus the needs of the virtual city, the practical interaction on the table versus the theoretical calculations taking place inside the computer, the physical input versus the digital output.

summary	Previous studies have described the effects of urban attributes such as the Spatial Openness Index (SOI) on pedestrians’ experience. SOI uses 3-dimensional ray casting to quantify the volume of visible space from a single viewpoint. The higher the SOI value, the higher the perceived openness and the lower the perceived density. However, the ray casting simulation on an urban-sized sampling grid is computationally intensive, making this method difficult to use in real-time design tools. Convolutional Neural Networks (CNN), have excellent performance in computer vision in image processing applications. They can be trained to predict the SOI analysis for large urban fabrics in real-time. However, these supervised learning models need a substantial amount of labeled data to train on. For this purpose, we developed a method to generate a large series of height maps and SOI maps of urban fabrics in New York City and encoded them as images using colour information. These height map - SOI analysis image pairs can be used as training data for a CNN to provide rapid, precise visibility simulations on an urban scale.

summary	The influence of urban morphology on the energy consumption of a fabric has been recently established by research into the energy use of existing cities. This paper suggests a framework for generating environmentally adapted urban tissue by using genetic algorithms as form-finding processes. A series of multi-objective optimization algorithms are described. The geometric abstractions used as a basis for these algorithms are illustrated in detail, and the results and implications of these types of simulations are discussed. The methodology developed within this paper was tested on one km2 site in three cities of varying climates, and further expanded into a detailed case study within one city.

summary	The representational and visual aspects of architectural de- sign education cause certain pedagogical stresses in student’s capaci- ties to learn how to code, and this paper will serve as a critique of the current state of algorithmic pedagogy in architectural education. The paper will suggest that algorithmic curriculum should not frame code as ‘a design tool’, but as something to be designed in its own right; the writing of the code is the ‘design brief’ itself and not something addi- tional to an architectural design brief. The paper will argue for an ar- chitecture-less educational environment that focuses on computational competencies such as logic, loops and lists along with building a strong analytical basis for students’ understanding of programming and digital geometries.

summary	This thesis explores the phenomenon of community networking in Canada, particularly as it impacts the issue of universal access to emerging broadband networks. The regulatory context of community networking is examined, and recent government efforts reviewed and critiqued. Through two case studies, an analysis of three potential benefits arising from community networking is developed. These three benefits are: increased participation in the democratic system, increased access to education, and community development. Several models for providing universal access, through community networks, are presented.
