title	The Prestige and the Money – the Main Goal and the Main Tool in Planning of the City Image in the 21st Century?
source	ENVISIONING ARCHITECTURE: IMAGE, PERCEPTION AND COMMUNICATION OF HERITAGE [ISBN 978-83-7283-681-6],Lodz University of Technology, 23-26 September 2015, pp.299-308
summary	This paper discusses the process of changing in the historical town – Baku in Azerbaijan in comparison to the achievements of European urban planners and architects (for example in: Paris, Vienna, Dublin). In Baku the fast and unlimited development and many investments in the public spaces have caused a lot of transformation not always to the better vision of the image of the city. At the same time, the development in some European cities is proceeding in other ways, preserving existing historical built environment.

title	Biomimetic-Computational Design for Double Facades in Hot Climates - A Porous Folded Façade for Office Buildings
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 687-696

summary	Biomimetic design is an approach that is gaining momentum among architects and designers. Computational design and performance simulation software represent powerful tools that help in applying biomimetic ideas in architectural design and in understanding how such proposals would behave. This paper addresses the challenge of reducing cooling loads while trying to maintain daylight needs of office buildings in hot climatic regions. Specifically, it focuses on double skin facades whose application in hot climates is somewhat controversial. Ideas from nature serve as inspiration in designing a porous, folded double façade for an existing building, aiming at increasing heat lost by convection in the façade cavity as well as reducing heat gained by radiation. The cooling loads and daylight autonomy of an office room are compared before and after the proposed design to evaluate its performance.

summary	Computation, in the context of a digital designing process, is redefining architectural practice. Architects are developing new sets of tools which are dramatically changing the typical way of design procedure. The paper describes the research assumptions, problems and solutions proposition, aimed at creation of a real-time form finding tool for architects based on engineering methods. Through intersecting architectural form evaluation with engineering analysis and optimisation tools it is highly intended to offer the opportunity to variety of architects and designers to use the exceedingly complex and compound process for their design improvement. The form finding tool, to be effective and reliable, has to provide immediate feedback to a designer. This requirement enforces a software developer to use more sophisticated solutions. The paper focuses on possibilities of already known engineering procedures acceleration such as Finite Element Method or Topology Optimization for effective implementation in architectural design process.

summary	The authors of this article argue for 'making time appear' in computational materials and objects so that it can be used to help people become aware of their relation to their environments. [Hallnäs & Redström 2001] As more computational and responsive materials come into play when designing architectural spaces designers might consider opening up the dimension of time to 'make time appear' rather than disappear. [Hallnäs & Redström 2001] Computational materials are materials which transform expression and respond to inputs read by computer programs. Making time appear can have many uses particularly in applications where people can be helped by the awareness of unfolding of time, where the temporality is linked to transformative body experience rather than project efficiency or collapsing distance. If architects, designers, engineers and others could begin to consider and use time as a way to promote reflection then it would be possible to design materials which could expand human thinking through the material itself.

summary	This paper explores four factors contributing to the revival of stone masonry; aesthetics, externalities, representational tools and cutting technologies. The ongoing desirability of stone for architects and designers for aesthetic reasons; sustainability benefits of stone due to its potentially reducing hidden externalities of production and transportation; the development of representational tools in terms of advances in computer aided design, simulation, analysis and manufacturing; and advances in production technologies. This paper focuses on how digital technologies are making stone a viable material for architects and designers.

summary	The current paper develops and extends the methodology of the geometrical description of urban outdoor places, formerly defined as the index keys method. The previously defined features of street and square profiles and skylines, i.e.: central angle, regularity and corrugation, are further completed with variations which develop into a clear, mathematical explanation of the basic notions defining genius loci, including the scale and atmosphere of a place. Altogether, the geometrical analysis defined here stems from the descriptions of urban settings with regard to culture related issues. It also reveals some of the morphological processes in the transformation of urban settings which took place in the discussed locations. The algorithmic method, namely the use of Grasshopper scripting, has been applied for the automation of the process. The preliminary results of analyses are presented as well as further research pathways.

title	The Computation Turn in Structural Performance Based Architecture Design
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 211-225.
summary	It is necessary for an architect to engage closely with structural design, to interpret their design idea thoroughly, and it requires carefully collaboration between architect and engineer. The structural performance based design is not only to obey structure principle but to explore different possibilities of engineer and architectural innovation. Architects could apply this method in the earlier stage of design, and it could provide the efficient solution for structure, create a new spatial experience and further improve the construction quality in the later phase of development. In comparison to structural performance-based design in history, the computational technology has made it possible for architects to implement further the structural knowledge in more dynamic and sophisticated environment. This paper will discuss the history development and current transformation of this method. Three research project will explain the current experimental design process and back the idea of this method.

title	Gradient-Analysis - Method and Software to Compare Different Degrees of Complexity in the Design of Architecture and Designobjects
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 415-424

summary	The aim of the research presented in this paper is to provide an additional method and tool for architects and designers as well as students and scholars to analyze the degree of complexity of a design. Fractal analysis (box counting) e.g. is one of these methods already used in architecture to measure the degree of complexity of an architectural design, for example of the elevation of a building. The method of semi-automated gradient-analysis described here focuses on the repetition of gradients and thus of proportion-repetition in a given design as one of several aspects of complexity reduction by redundancy.

summary	This paper addresses the needs of exhibition curation with the concept of a virtual gallery (which may or may not be translated into reality). Curation is often an overly linear process - as opposed to an iterative exercise, whereby collaboration between stakeholders is somewhat limited by time, distance and the opportunity for virtual communication. This suggests that the implementation of a system for sharing visual data - especially in the real-time mode that a virtual studio might offer - could facilitate a more dynamic and iterative design process, where the design team remains engaged throughout.Two (architectural) designers - from Vienna, Austria and Liverpool, UK - are collaborating to create a process for exhibition design for existing venue, involving international stakeholders in remote locations. The key outcome for this research is to create a framework for future collaborative workflow that enhances the delivery of exhibition design through improved decision-making, without the need for all of the team to have extensive software knowledge.The paper thence reflects on current experience, reporting changes in curatorial processes and suggesting areas of added value that might benefit future works.

summary	Being overwhelmed by computing technologies, we are forwarding more and more of our skills into area of "thinking by head". Our designing capabilities are turning into capabilities of "how to work with very intelligent technology". The processes of human brain, nevertheless, are different to the processes in computer. Designers are said to think by hand. As architects we are looking for final forms that not only fulfil the technical requirements, but are beautiful as well. Therefore sketching is one of the skills that belongs to an architect in order to design and particularly to work in a team. The workshop will accordingly focus on sketching on electronic devices in comparison with sketching on paper. Is it actually possible to switch to tablets when sketching? If yes, which application is the best to use? In order to find that out, there will be a test of three applications: ColLab Sketch, Queeky and FlockDraw. The participants will be sketching on-line and helping to find the best way of communication by sketch. By drawing they will become a part of the research, their work will be post-produced and exhibited at the welcome dinner.

title	Algorithmic Thinking in Design and Construction - Working with parametric models
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 19-28
summary	This paper examines the parametric model in algorithmic design processes, using the outcome of an educational digital design and fabrication course as a case study. In its long history, algorithmic design as a form-finding method, allowed designers to manage complex non-standard associative geometries, suggesting a shift from the digital representation of form, to its systematic representation into a parametric model through code. Rather than a style or a tool, the parametric model is best defined in mathematical terms; in practice it incorporates the organizational logic of the form and the topological associations of its parts, so that a change in its constitutive parameters will invoke a concerted update of the entire model, and, iteratively, formal and structural variations. In a series of design experiments that took place at the School of Architecture of the Technical University of Crete in the spring of 2015, we used parametric models represented into visual code, from the initial conceptual stage to fabrication. From the experience and outcome of this course, we deduced that, compared to other digital formation methods, parametric models allow the designer to constantly interact with the model through the code, producing discreet variations without losing control of the design intentions, by “searching” into a wide range (albeit finite) of virtual results. This suggested a shift in culturally embedded patterns of modernist design thinking.

summary	The number of variables acting upon urban landscapes is numerous and interconnected, closely resembling complex systems in constant dynamic transformation. Current analytical methods and descriptions of the city are domain specific, limited in scope, and discretize the city into quantifiable individual representations, resulting in an equally limited urban policy and design. If we are to produce urban systems capable of contributing to the robustness and resiliency of cities, we ought to understand and represent the comprehensive network of actors that construct contemporary urban landscapes. On one hand, the natural sciences approach the analysis of complex systems by primarily focusing on the development of models capable of describing their stochastic formation, remaining agnostic to the contextual properties of their individual components and oftentimes discretizing the otherwise continuous relationships among parts. signers work in groups. They need to share information either synchronously or asynchronously as they work with parametric modeling software, as with all computer-aided design tools. Receiving information from collaborators while working may intrude on their work and thought processes. Little research exists on how the reception of design updates influences designers in their work. Nor do we know much about designer preferences for collaboration. In this paper, we examine how sharing and receiving design updates affects designers’ performances and preferences. We present a system prototype to share changes on demand or in continuous mode while performing design tasks. A pilot study measuring the preferences of nine pairs of designers for different combinations of control modes and design tasks shows statistically significant differences between the task types and control modes. The types of tasks affect the preferences of users to the types of control modes. In an apparent contradiction, user preference of control modes contradicts task performance time.

summary	In the aspiration to design the built environment, architects and designers are continuously trying to create spaces that positively affect users. Both aspects of rational and emotional combined simultaneously with technological advancement are essential to implement in a comprehensive architectural design process. While our ability to create complex architectural forms through computation is in the state of a continuous improvement, our knowledge about their emotional effects over users remain ambiguous. Recent developments in simulation of virtual spaces, along with advancement in neuroscience may enable us to conduct an empirical research on the way we perceive space and the way space affects us emotionally. This paper presents initial results from an ongoing research that examines the connection between human feelings and architectural space. We discuss the first stage of the research in which as we examine the emotional reaction of designers and non-designers to various spatial geometries in an immersive 3D virtual environment inside a visualization laboratory. We then present the methodology for the second stage of the research, in which we repeat the experiment while using Electroencephalography (EEG) device together with a wireless eye tracker and emotional engagement measurements (EEM) system.

summary	Computer-aided design tools have become an integral part of much architectural design practice, to the point where design is heavily dependent on the assistance of these tools. But current computer-aided design tools are fundamentally limited by the WIMP (windows, icons, menus, and pointer) interface, reliant on 2d input and output. Design of buildings and other 3D objects via 2D workflow is slowed by the conversions that designers must make. In this paper, we explore the potential of transformable physical design media through two design tool prototypes: Integrated spatial gesture-based direct 3D modeling and display system (InSpire), and tangible objects based massing study tool kits (CuBe). Both of these design tool prototypes allow designers to develop their design within a fully 3d environment with optical and haptic references, so that the interaction between designer and design object become much more intuitive and direct.We conclude by discussing some related subjects in the domain of HCI and argue that transformable physical design media represent a desirable solution for enhancing design experience. Architects and designers could benefit from the usage of transformable physical design media, especially during the early phases of architectural design by allowing designers to efficiently alter the topology properties.

summary	Digital fabrication technologies are changing rapidly the way we design, as any other tool would affect the way we produce space. Multi layered 3D printing is already allowing architects, designers and engineers to experiment with new design processes and new ways of production. At the same time, little research has being done in the way gradient transparency (through multiple layered surfaces) can affect the design process through computation; a field that deserves further investigation. The focus of this paper is to explore bio-inspired material finding design processes while combining biology, architecture and material science. We explore performance driven design possibilities through a study of marine animals -and specifically cephalopods- where opacity between skin layers is controlled through color pigments - while black pigments are called melanophores - which is often used as a type of camouflage. We propose a computation model that follows the logic of gradient transparency through pigments to fit complex “host surfaces”. We define a “host” surface as a basic geometry on which the pigments are computed. This study provides the methodology for the design of biomimetic surfaces with gradient transparency, using controlled and computated sub geometries analogous to the melanophores pigments. We finally propose Pigment Skin, a computational design model as an example to materialize this study.

title	An Empirical Foundation for Design Patterns in Parametric Design

summary	This paper presents the results from exploring the impact of using a parametric design tool on designers’ behaviour in terms of using design patterns in the early conceptual development stage. It is based on an empirical cognitive study in which eight architectural designers were asked to complete two architectural design tasks with similar complexity respectively in a parametric design environment (PDE) and a Geometric modelling environment (GME). Protocol analysis was employed to study the designers’ behaviour. To explore the development of design patterns during the design process, we utilise the technique of Markov model analysis. Through Markov models analysis of the PDE and GME results, we found that there are significantly more Function to Structure transitions in PDE than in GME. During this transition process, designers select an existing structure/solution for the particular function/design problem based on their experience or knowledge, which is a process of applying an existing design pattern to the problem. From this result we can infer that when architects apply programming and scripting in their design, such as in a PDE, they exhibit the characteristic of using design patterns.

title	Architects' Cognitive Behaviour in Parametric Design
source	International Journal of Architectural Computing vol. 13 - no. 1, 83–102
summary	This paper presents the results of a protocol study of professional architects' cognitive behaviour in a parametric design environment. A design experiment was conducted in which eight professional architects completed an architectural conceptual design task in a typical parametric design environment -Rhino and Grasshopper. Protocol analysis was then applied to analyse the cognitive behaviour of the architects. In analysing the protocol data, the FBS ontology adopted for developing the coding scheme was sub-divided into design knowledge and rule algorithm classes as the means to capture designers' cognitive behaviour. Applying the method of cumulative analysis, results of the relative cognitive effort expended on design knowledge and rule algorithm classes have been compared and are discussed in the paper.

title	Poisson's Ratio Material Distributions

doi	https://doi.org/10.52842/conf.caadria.2015.735
summary	The Poisson’s ratio of materials describes the ratio of the transverse to axial strain. While most materials exhibit non-negative Poisson ratio, here we focus on the topological properties of negative ratio materials also known as auxetic constructs. Digital modelling and physical fabrication are employed to generate and test experimental auxetic configurations. The first set of studies employ 2D space-filling tessellations integrating both negative and positive Poisson ratio cells. The tessellations are designed through binary state transitions and gradual morphing transitions. A second set of studies explores the topological optimization of a single negative Poisson cell configuration following the logic that a cell constitutes the building block of auxetic materials. The third set of studies focuses on the translation of heterogeneous Poisson ratio 2D tessellations into 3D constructs. Here, two methods of fabrication are explored: lamination method and cellular grading. The precision of the cellular grading method renders it particularly suitable for multi-material 3D printing fabrication which is theoretically studied and proposed. Space-filling heterogeneous tessellation studies are applied to architectural and product design proposals. These proposals exhibit properties that could serve to design and develop further research on real-world applications.

title	Digital Design of High-Rise Buildings with Tessellation and Mapping

summary	A new high-rise building, when inserted in an existing urban environment, cannot have all the floor plans identical since the visual and environmental constraints change from floor to floor due to the interference of neighboring buildings, sun light, prevailing wind and noise. So how can we design a building that takes into consideration all this variables? How can digital design tools help? (DELPINO, 2014). We believe that a building like that can be designed constructing facade maps which allow a floor by floor analysis considering visual, wind, noise and sun light constraints. We believe that facade maps analysis and their superposition provide clues of how each floor plan can be built to provide comfort and to take most advantage of the view. (DELPINO, 2014). We believe that variation techniques such as tessellation and morphing can provide the formal bases for such design. We believe that digital design tools are vital both for analysis as well as for designing this type of building. (IWAMOTO, 2009, p. 35-59; MOUSSAVI, 2009, p. 42-216).

title	AI-Assisted Design: Utilising artificial intelligence as a generative form-finding tool in architectural design studio teaching

summary	Artificial Intelligence (AI) tools are currently making a dynamic appearance in the architectural realm. Social media are being bombarded by word-to-image/image-to-image generated illustrations of fictive buildings generated by tools such as ‘Midjourney’, ‘DALL-E’, ‘Stable Diffusion’ and others. Architects appear to be fascinated by the rapidly generated and inspiring ‘designs’ while others criticise them as superficial and formalistic. In continuation to previous research on Generative Design, (Agkathidis, 2015), this paper aims to investigate whether there is an appropriate way to integrate these new technologies as a generative tool in the educational architectural design process. To answer this question, we developed a design workflow consisting of four phases and tested it for two semesters in an architectural design studio in parallel to other studio units using conventional design methods but working on the same site. The studio outputs were evaluated by guest critics, moderators and external examiners. Furthermore, the design framework was evaluated by the students through an anonymous survey. Our findings highlight the advantages and challenges of the utilisation of AI image synthesis tools in the educational design process of an architectural design approach.
