title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	This research aims at stimulating the exploration process in architectural design through the conception and the creation of a computational environment centered on a library of referents. Based on a specific way of describing the referents, as well as on the energizing role we wanted the library to play in the design process, we could draw the characteristics of such an environment. The representation of the referents is seen as a combination of descriptions in different format. Offered to students, it allows for new interpretations, for interaction with their content, and finally, for the integration of knowledge during the process of architectural exploration.

title	Programming framework for architectural design ANAR+: Object oriented geometry
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary	From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

title	Teaching Systems-Thinking with Algorithmic Process: Introduction to computation and programming with processing programming language
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 37-46
summary	This research investigates how algorithm design and scripting as pedagogy can affect generalized design ability and understanding. Logical, systematic thinking is considered foundational in developing architectural design aptitude and is explicit when designing algorithms. The course work presented mandates the construction of process rather than product. Scripting is implemented not as a means to an end but rather a medium for exploration. More valuable than formal generator or problem-solver, these scripted designs test direct aesthetic implications. Further tested is the role of animation in de-linearizing the design process. By isolating the algorithm as topic, technique, and concept, scripting skills and the produced artifact are extendable and are translatable to other media. Algorithm design is presented as a 2-dimensional but temporal endeavor: students script an animate, interactive vector-based image. This facilitates the transition from algorithm to spatial experience while also readying students for form-based explorations. The 2-d temporal exercise is of a similar order of complexity to a 3-dimensional static condition. Pieces of the animation structure are provided as a canvas, specifically the ability of the viewer to manually control a single parametric variable that affects the visual output through a user-interface element. The following and final project of the course expands upon the technique of scripting image in the design of an experience by collaging video, images and animation.

title	Collective Intelligence: An Agent-Based Approach to Programmatic Organization in Architecture
source	International Journal of Architectural Computing vol. 7 - no. 3, 479-499
summary	Architectural programming is the research and decision-making process that identifies the scope of work to be designed. Programming is difficult because it involves identifying, collecting, analyzing and updating information from different sources such as engineers, clients, users, consultants, and others. In this paper I propose a computational model for programming and describe its implementation, a tool called PENA that allows a programming expert to represent different processes and people involved in a project using intelligent agents. By delegating responsibility to agents, a programming expert can better organize and manage project data as well as find creative solutions to conflicting issues through agent negotiation. As a proof-of-concept, I show how an agent, called the Arch-Learner, manages adjacencies of rooms in a simple program for a house by clustering them into public and private rooms. I conclude with a discussion of future work and development of PENA.

title	The Role of Visual Platforms -visual Social Media- in the Creative Design Process
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 639–650
summary	In the current design practice, new digital tools have emerged -visual- also called Infrastructures (Perkel, 2011) such as; Behance 2003, Pinterest 2009, Archdaily 2008, Instagram (2010) -to cite the most recognized in the creative field in Argentina-, which promote different opportunities and support the creative process and problem solving, making it easier for designers to find inspiring material through the Internet. However, very little is known about how these new practices affect professional work, how they themselves see it and the tensions they generate.This article will present the results of a general survey applied to expert designers as part of the first stage of the Doctoral Research project. Which investigates the behavior referred specifically to the use of visual platforms -visual social media- in order to understand, characterize, describe the use and involvement of them within the design process.

title	Appropriating Donald Schön

summary	Donald Schön embraces a constructivist approach to learning and research., characterising designing as a reflective conversation between designer and the materials of a design situation. Accordingly, Schön’s views on digital design support are based on his valuing of indeterminacy, surprise and ambiguity as opportunities to develop new understanding and insight. His criticism of technical rationality is directed towards the privileging of formal and codified knowledge over embodied and tacit forms of knowing. While Schön’s work is increasingly acknowledged in recent CAAD research, respective publications typically remain within the technical rationality perspective. Based on several characteristic examples, this paper examines how Schön’s ideas are absorbed into a perspective incongruous to his own, concluding with a discussion of potential new research approaches that sustain Schön’s values.

summary	The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 5-12
summary	This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects’ use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and unique contexts and site conditions. The masonry module is designed and built through the exploration of a CAD-CAM process. The prototypes produced investigate the repetition of a single module unit, manipulated and interlocked resulting in a continuous surface that is more than just the sum of its individual parts. The material, construction and craft of each unit informs and challenges the entire project to question the making of the masonry module into a wall.

summary	We investigate the recent coincidence of rapid global urbanization and unprecedented formal freedom in architectural design and ask whether this coincidence is an uneasy one. To study an extreme case of the new exotic geometries made possible through CAAD, we employ algebraic surfaces to experimentally design architecture in an university-based research and experimental design project. Such surfaces exhibit unprecedented complexity and new geometric and topological features yet are highly sound and harmonious. We continue and extend our research presented at the eCAADe 2009 conference in Istanbul.

summary	We describe the exploration of the manifold novel shapes found in algebraic geometry and their application in architectural design. These surfaces represent the zero-sets of certain polynomials of varying degrees. They are therefore very structured, coherent and harmonious yet at the same time geometrically and topologically highly complex. Their application in design is mostly unprecedended as they have only recently begun to become accessible through novel software tools. We present and discuss experimental student design and research projects where shapes found in algebraic geometry were developed into pavilion designs. We describe historic precedents for the inspiration of art and architecture through mathematics and show how algebraic surfaces can be used to expand architects’ sculptural vocabulary, make the utmost of three-dimensional sculptural qualities, employ shapes that have a strong internal structure, transcend the imaginable and explore polynomials as a new kind of shape-making tool.

title	Gis in Architectural Education: Design as a place-making process
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 393-407
summary	Responsiveness to site conditions and environment is one of the axioms of architectural design. However, most students’ design is made in a non-geo-coordinated cyberspace through CAAD design and thus leading to “flying” proposals” that are not attached to the context. GIS teaches students in architecture to initially refer to real locations as the space in which they design is geo-coordinated and provides the wider context of the project. Along the design process, the project surroundings from macro scale; that is the globe, to the micro-scale that is reflected in the existing buildings, the road network and the topography are constantly present. At the end stage, the project is seen not as a free standing building but rather as an integral part in a real place on Earth. The 3-D urban visualization gives the possibility of evaluating the degree of success of place-making and the fitness of the project to its context. The aim of the paper is to present how a GIS course can support CAAD and improve the architectural design process as well as the quality of the design output towards a contextual architecture. The paper is based on the experience of the author who is architects and urban planner, in teaching design studios and Urban Planning based on GIS as an elective course to graduating students in architecture at the University of Bahrain. It presents an alternative method that is called Permanent Presence of the Real World PPRW.

summary	The goal to reach Simplicity has been the key point of Human- Computer Interface since 1980s. In this research, we would like to know what Simplicity is and how to reach it. We used case studies to get two factors of Simplicity, which are the information modeling and the experience of perception through senses. Based on the factors, we implemented a prototype to refine the concepts of simplicity. The prototype was a new attempt to consider only the simplicity of HCI. Further research efforts on emotion, creativity, and aesthetics related to simplicity are important.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 461-470
summary	This research attempts to integrate a new technology–Multi- Display Environment (MDE)–into the design and creation of new architectural spaces–multi-display spaces. The research objective is to formulate a set of design guidelines that advise designers on the effective use of the MDE technology, so that the technology may become a new design element and enables designers to show amplification effects of spaces. Two empirical studies are conducted. Based on the results of empirical studies, a set of multi-display space design guidelines is formulated with three key aspects: scene selection, display allocation and display arrangement. The design guidelines require further validations through practical applications. Nevertheless, the research introduces a new design element for designers to think about the future of architectural spaces with more opportunities and possibilities.

summary	The research effort presented here is based on the view of emergent behaviors. The aim is to develop smart building products each of which is independent, self-sufficient and with very limited intelligence. Using “Basic Building Block” as a platform, three building products, interactive louvers, see-through wall panel, and sensible floor tile are developed to illustrate the emergent smart behavior. These smart building products contain intelligent technologies that can be implemented into existing buildings incrementally without having to perform major renovations.

summary	This research intends to provide a comprehensive understanding and tectonic patterns of responsive architecture. By qualitatively analyzing a series of critical responsive buildings from Ito’s early Wind Tower through Diller and Scofidio’s Blur Building to Cloud 9’s recent Habitat Hotel, tectonic themes of “lightness”, “morphing”, ”improvisation”, and “networking” are set to the elucidate methodological relationships between their tectonic expressions and design concepts. Based on these designated themes, manipulation of materiality, techniques of construction, and mechanism of responsiveness in the studied cases are comparatively discussed and demonstrated with visualization of their tectonic design patterns. The objective of this research is to stress on the importance of tectonic consistency and offer evidences in combining physical components with digital configurations in order to achieve poetic expressions of structure, function, as well as aesthetics so that genuine spatial quality for digital era can be truly revealed.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

title	Dynamic Relaxation of Tensegrity Structures
doi	https://doi.org/10.52842/conf.caadria.2009.553
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 553-562
summary	The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these are aggregated in a tensegrity however, the performance of the assembly as a whole is non-linear. In order to investigate further these relationships a method of dynamic relaxation will be developed. This tool allows for simulation and load analysis of a complex tensegrous network, based on the relationships between force, stiffness and dimension formulated by Young and the computational means provided by a parametric/associative modeling environment. This research investigates the possible formfinding through computational means of a double-layer tensegrity grid.

summary	In experimenting with digital processes for simulating the behavior of tension-active cable nets, a method was developed for creating informed geometries by utilizing computational meshes that carry properties of structure, space, and material. A spring-based particle system provided the dynamics to simulate the flow of tension force through the geometry. Particular functions were scripted to embed logics for fabrication and analysis of spatial parameters. This formulated a lightweight, reactive design tool for which multiple cable net morphologies could be quickly generated. This paper will describe the experiments in creating the method to generate such cable net morphologies, and discuss the potential application for this computational framework to apply to other architectural systems.
