title Harnessing Design Space: A Similarity-Based Exploration Method for Generative Design
source International Journal of Architectural Computing vol. 13 - no. 2, 217-236
summary Working with multiple alternatives is a central activity in design; therefore, we expect computational systems to support such work. There is a need to find out the tool features supporting this central activity so that we can build new systems. To explore such features, we propose a method that aims to enable interaction with a large number of design alternatives by similaritybased exploration. Using existing data analysis and visualization techniques adopting similarity-based search, we formalized the method and its elements by focusing on systematic filtering, clustering, and choosing alternatives. We present a scenario on developing conceptual designs for a residential apartment to illustrate how the method can be applied, as well as to reveal the limitation of current tools and the potential interactive clustering and filtering features for the new systems coupled with parametric design.

title Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures

summary The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

summary Detection of emergent shapes in sketches requires extensive exploration of the design space. Automating this process with computational methods enables locating various alternatives sequentially or all at once simultaneously via high computational power. This not only helps efficient design space exploration but also provides a systematic way for keeping track of the design process. However, it is a challenge to define a generic computational method which optimizes the design space searches in time and space. The approaches that are based on optimization may suffer from time efficiency and local minima problems. These problems are substantially solved in this work by performing comprehensive parallel searches in the design space with a genetic algorithm. Advantage of this approach is that the local minima problem is reduced significantly without increasing the execution times.

title Making Sense of those Batteries and Wires: Parametric Design between Emergence and Autonomy
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. 279-296.
summary This paper reports on the process and outcomes of a digital design studio that integrates parametric design and generative systems in architectural and urban design projects. It explores the interrelationship between the emergence of innovative formal representations using parametric design systems on the one hand, and design autonomy; more specifically the conscious process of generating and developing an architectural concept, on the other. Groups of undergraduate students working on an architectural project are asked to identify a specific conceptual parti that addresses an aspect of architectural quality, define strategies that satisfy those aspects, and computational methodologies to implement those strategies, such as rule-based systems, self-organization systems, and genetic algorithms. The paper describes the educational approach and studio outcomes, discusses implications for CAAD education and curricula, and addresses issues to be considered for parametric and generative software development.

summary In continuation to the Deceptive Landscape Installation research project (Agkathidis, Kocatürk 2014), this paper investigates the implementation of generative design techniques in undergraduate architectural design education. After reviewing the main definitions of generative design synoptically, we have assessed the application of a modified generative method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of the design outputs, student performance, external examiners reports as well as student course evaluation surveys indicate a positive outcome on the studio's design approach, as well as its suitability for an undergraduate design studio. They initiate a flourishing debate about accomplishments and failures of a design methodology, which still remains alien to many undergraduate curricula.

summary This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title Re-inventing ceramic tiles: Using shape grammars as a generative method and the impact on design methodology
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. 467.
summary The following paper describes the process and results achieved with the workshop entitled ‘Re-inventing Portuguese ceramic tiles’ reflecting on design methodology and design teaching. Workshop participants were invited to rethink ceramic tile patterns developing a different process which used shape grammars as a generative system. Each participant group developed a three stage task using shape grammars principles and methodology. The preliminary results the work developed are of particular relevance in shape grammar research: firstly shape grammar formulae does not constitute an intuitive process to most creative designers which are often trained to design singular solutions for a specific problem, secondly more than one operative shape grammar can be formulated to represent the same corpus of solutions and lastly the generative potential of grammars transcends the normal capacities of the original grammarist aiding in design exploration and enlarging the corpus of feasible solutions. This paper also reflects on the impact of shape grammars as a design methodology.

title A window to the autism: the political role of the difference of an objectile in the homogeneous school
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 848-853
summary This paper approaches the insertion of an objectile in the homogeneous space of a school, looking to bring flexibility and responsiveness to assist a user with Autism Spectrum Disorder (ASD). The research concerns with photosensitivity, a problem faced by almost 25% of the children with autism (Miller-Horn; Spence; Takeoka, 2011). The study is based on the theories for ASD environments that speak of ‘sensorial perception’ and ‘thinking with imagery’ (Mostafa, 2008), and the coexistence of Sensory Design Theory and Neuro-Typical Method (Pomana, 2015). The result consists of a gadget developed in MIT App Inventor tool and a curtain that interact responsively through an Arduino code, for a new connection between the user and his surroundings.

summary In order to support exploration in the early stages of the design process, researchers have proposed the use of population-based multi-objective optimisation algorithms. This paper focuses on analysing the resulting population of design variants in order to gain insights into the relationship between architectural features and design performance. The proposed analysis method uses a combination of k-means clustering and Archetypal Analysis in order to partition the population of design variants into clusters and then to extract exemplars for each cluster. The results of the analysis are then visualised as a set of charts and as design models. A demonstration of the method is presented that explores how self-shading geometry, envelope materials, and window area affect the overall performance of a simplified building type. The demonstration shows that although it is possible to derive general knowledge linking architectural features to design performance, the process is still not straightforward. The paper ends with a discussion on how the method can be further improved.

title Performance-Based Parametric Design : A Framework for Building Envelope Design

summary Existing performance-based design exploration methods typically suffer from a lack of real-time feedback and a lack of actionable feedback. This paper proposes a hybrid design exploration method that overcomes these issues by combining parametric modelling, surrogate modelling, and evolutionary algorithms. The proposed method is structured as a mixed-initiative approach, in which parametric modelling is the key to creating a synergistic relationship between the architect and the computational system. Surrogate-based techniques will address the issue of real-time feedback, the evolutionary exploration techniques will address the issue of actionable feedback. As a first stage in developing the PEX method, this paper reports on two experiments conducted to identify an appropriate surrogate modelling technique that is efficient and robust.

title Analysis of Space Layout Using Attraction Force Model and Quadratic Assignment Problem

summary This paper researches the usefulness of computerized space layout programs in an actual problem of space layout of more than 50 design units of unequal sizes. This was tested with two existing space layout optimization methods, Quadratic Assignment Problem (QAP) and Attraction Force Model (AFM) as well as a satisficing method, intuitive approach. Necessary inputs for the evaluation processes, the evaluation processes and the resulting space layouts were analyzed for each approach by one designer. Their performance in the design process was criticized on subjects like preparation of inputs, situations related with multiple trials, evaluation of the resulting space layouts based on given inputs and what those space layouts represented. Generating alternatives is an advantage of computerized space layout approaches so that conditioning on the resulting space layouts decreases in the process but more research has to be done for their practicality in terms of input preparation, evaluation and transfer of outputs. Possible improvements were suggested to increase their usefulness in the professional field.

title Interactive Design Exploration with Alt.Text
source International Journal of Architectural Computing vol. 13 - no. 2, 103-122
summary It is well accepted that search is an effective model for design. Newell and Simons’ Human Information Processing model is foundational to this view. Designers use symbols and structures to express, store, off-load, recall, and manage their work. They mix general and detailed elements, organize their problem-space differently, seek ways to identify repetitive tasks, and utilize external media. An integral aspect of design-search is the comparison of alternatives, because the goal is usually to come close, if not fully satisfy, a set of requirements. Searching problem-spaces with currently available tools is challenging due to a number of issues related to creating and comparing alternative representations of one’s thought process and outcome. In this paper, we present Alt.Text, a prototype that we developed to explore strategies for supporting design search. While Alt.Text only handles text-based documents, we believe that many of its features can be generalized to the domain of architectural design.

summary With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary Environmental analysis as part of the initial design process, affords precise consideration of the bioclimatic human conditions within the environmental local context. The daily growth in inter alia knowledge of effective parameters in environmental conditions, quality weather data, human thermo-physiology studies – all contribute to improving the potential for achieving a relatively accurate analyses of environmental conditions by overlaying and computing all the climatic and thermo-physiological data. This paper describes a digital method for examining different points in the same context by computing all the input data available to understand the corresponding human comfort condition levels, thus leading to better decision-making at early design stages. Information about the site, climate, human thermo-physiology and behavioral aspects among others are collected where each data parameter is matched and analyzed to the context of every node on the model through a series of specific computational algorithms. Thereafter, the data from the nodes are statistically cleaned, classified and integrated based on the CBE thermal comfort calculation for ASHRAE-55. The results obtained using this method, can be tailored according to the desired outcomes. The proposed method identifies effective factors for human comfort condition improvement for different points on the context. It also provides a means to priorities specific parameters so that they can be manipulated for optimal digital design solutions, ie. Aligned to the desired conditions in the specific parts of the site with the aim of optimize outdoor space usage.

summary The building needs to be designed to minimize its environmental footprint and to be sufficiently adaptive to changing indoor and outdoor environmental conditions. The smart building envelope is an interactive system which is adaptive to environmental conditions by transforming its shape and functions. This is a kind of machine, not like a traditional building component, which should be based on integrated engineering design methods in addition to the exploration of formal aesthetics. As artistic genius or technical skill alone cannot not fully support the design of such a novel product, the design needs to be systemized by introducing a product development method such as prototyping in other industries. Prototyping needs to be integrated in school environment, even if it requires fundamental reconfiguration of current computer-based design studios. This paper aims at proposing a teaching methodology for educating the prototyping-based design of smart building envelope system in digital design studio. This methodology allows novice designers to operate interactions between virtual-physical models. And sketches are used to share ideas to other collaborators such as programming, mechanical operations without technical knowledge. The interactions between virtual-physical models and sketches contribute to not only complement virtual models and physical models, but also achieve high-performance of smart building envelope practically.

summary Our paper presents research on the development of technologies and methodologies to support preliminary design phases through data based modelling. A digital parametric model informs costs evaluations and supports iterative and visual space exploration solutions. Thanks to associative modelling, the architectural conception is renewed and digital tools support design decision-making in a creative way. We propose to make project cost a design parameter through an interactive handling of a 3D geometric model that is relevant to strategic architectural intentions. In our experimentation, cost calculation spreadsheets are linked to a parametric models. An initial substructure of the building cost is defined based on the architectural concepts. The parametric tool directly informs the evaluation spreadsheet and a real time cost analysis is afforded to the designer. The tool supports the design process by displaying immediate feed back to the designer who can consider and control the financial implications of his hypothesis.

The author outlines the processes developed by students, the tools they used and the final results of design studio project and the supporting seminar, focused on exploring information processes in design. For the purpose of the design studio the students developed their own generative strategies that allowed incorporating optimization procedures into the design process. Within the framework of the seminar classes students developed individual optimization tools with the use of genetic algorithms in order to explore the search space and select the best possible architectural solutions for the specified criteria. The students used the above-mentioned tools mostly during the building's form-finding design stage or attempted to optimize just the building structure.

summary In dealing with unexpected impacts of climate change current spatial planning tools are irresponsive and inflexible. The outcomes of applications of these tools are very limited in number, producing static plans that if implemented are very vulnerable to climate hazards. Therefore, an innovative generative tool has been developed to support spatial planning which results in designs that are responsive and adjustable to unexpected, simulated changes. The development of the generative tool is informed by swarm planning theory, and by contemporary generative approaches in urban design and planning. The generative tool is modeled as an Agent-Based System and utilizes versions of the canonical flocking algorithm. The agents are abstract cubical units of space that represent building envelopes. The agents exist and work within an environment that represents a site in terms of topography, land value, and available/buildable land. The agents receive information from the environment and act upon this information. The unexpected climate impact is a simulated flood, which affects both the environment and the agents. The outputs of the tool are generated 'bottom-up' in order to study emergent spatial configurations, as massings of building units.

summary The crisis of architecture is a crisis of form, therefore new approaches and definitions are necessary. The children´s game of Hide-and-Seek seems extremely relevant to learn the complex interplay of social interaction and space. What if its hiding places were to be designed by an architect? Is there a method to relate the rules of the game to the number, design and layout of its obstacles in such a way as to create a successful game?A possibility to tackle this problem is the use of metaheuristic solvers. But even for the simple game of Hide-and-Seek, their use is confined to cases with a very limited set of obstacles and players, since the time needed to calculate the fitness function increases rapidly. To overcome this we suggest the use of statistical methods to develop a heuristic fitness function based on properties which can be directly computed from the values of the genotype. The resulting function makes is possible to solve the given problem using a metaheuristic solver not only for the simple cases with 3 or 4, but also for those with n obstacles.

summary Thermocatalytic Metafolds comprises a paper-based fabrication process that initiates ascetic self-assembly via heat application. Metafolds utilizes a composite material of paper with a selectively applied shape-changing polymer crafted via a multi-step computational, two-dimensional drafting fabrication method. Upon heat application, the paper self-folds into predetermined, three-dimensional, highly accurate, rigid shapes. The final product maintains a notable resilience to alteration, and the stringency of form serves as a testament to the process’ potential to transform the ways in which design is undertaken. This exploration of material properties has cumulated in a process that demonstrates a design based on a detailed understanding of how the composite material behaves under specific conditions.
