summary	Recent developments in responsive electroactive materials are increasing the rate at which next-generation façade technologies can respond to environmental conditions, building energy demands, and the actions of building occupants. Simulating the real-time performance of dynamic façade systems is critical for understanding the impacts that occupant response will have on whole-building energy performance and architectural design. This paper describes a method for real-time analysis of the multi-zone building performance impacts of occupant interaction with a dynamic façade system, the Electroactive Dynamic Display System (EDDS). The objective is to optimize EDDS implementation and define system limitations, incorporate EDDS as a dynamic factor in multi-zone building energy analyses, and provide real-time feedback of building performance data based on environmental conditions and occupant interactions. Preliminary results of parametric simulation methods demonstrate the ability of dynamic façade systems to consider real-time occupant interaction in the analysis of daylighting and thermal performance of buildings.

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	Perceived Emotional Effects of Digital Pattern in Façade Design
doi	https://doi.org/10.52842/conf.caadria.2015.623
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 623-630
summary	This study raises the question of what the emotional significance of the digital patterns has and attempts to provide an answer to such a question. The purpose of this study is to propose a direction to effectively support the façade designs of buildings by understanding the emotive design characteristics of the patterns. This study explains the design patterns on façade designs. There are five types of digital patterns which include applied patterns, perforated patterns, layered patterns, cast patterns, and tiled patterns. Among those patterns, perforated patterns are focused in further detail. This study deals with identifying emotional effects of perforated design patterns. The emotional word ‘asymmetrical’ and ‘irregular’ shows the high average of the emotional value. In the bipolar adjectives, the high emotional value is ‘irregular-regular’ and ‘asymmetrical-symmetrical’. Therefore, the final design characteristics of the perforated patterns are ‘regularity’ and ‘symmetry’. This means to be able to use the perforated patterns in order to be perceived a building façade design as the regular and symmetrical emotional effect. In this paper, it is worth analyzing design characteristics of a building façade by the support of the digital technologies and discussing the utilization of design characteristics derived. This study has contributed to the process and method of deriving the analysis results.

title	Phototropism of Tensile Façade System through Material Agency
doi	https://doi.org/10.52842/conf.caadria.2015.127
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 127-136
summary	This paper researches material agencies, mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on plants and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The design approach of this research is based on a data-driven methodology spanning from design inception to simulation and physical modeling. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. The driving concepts are three types of evolutionary adaptation: flexibility, acclimation, and learning. The proposed façade system is a responsive textile shading structure which uses integrated actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli and ultimately effective performance of the whole system.

title	The geometry of Chuck Hoberman as the basis for the development of dynamic experimental structures

summary	The cognitive-theoretical foundation referring to teach drawing as a way of thinking, as well as the construction of the environment by means of drawing using transforming geometries and the formal and para-formal computational process, creating unusual geometries through generative design processes and methodologies, can be seen as some of the main possibilities in exploring dynamic experimental structures for an Adaptive Architecture. This article presents the development of a model for articulated facades, inspired by Hoberman´s Tessellates, and his Adaptive Building Initiative (ABI) project to develop facades models that respond in real time to environmental changes. In addition, we describe an experiment based on the retractable structures, inspired by Hoberman´s work and experimentations. Solutions for responsive facades can offer more flexible architectural solutions providing better use of natural light and contributing to saving energy. Using Rhinoceros and the Grasshopper for modeling and test the responsiveness, the parametric model was created to simulate geometric panels of hexagonal grids that would open and close in reaction to translational motion effects, regulating the amount of light that reaches the building.

title	The definition of semantic of spaces in virtual built environments oriented to BIM implementation
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. 331-346.
summary	The BIM today can be a provider of inputs to performance analysis of different phenomena such as thermal comfort, energy consumption or winds. All these assessments are fundamental to the post occupation of the building. The attainment of approximate information of how the future building would behave under these conditions will reduce the waste of materials and energy resources. The same idea is used for evaluating the users occupation. Through simulation of human behavior is possible to evaluate which design elements can be improved. In complex structures such as hospital buildings or airports is quite complex for architects to determine optimal design solutions based on the tools available nowadays. These due to the fact users are not contemplated in the model. Part of the data used for the simulation can be derived from the BIM model. The three-dimensional model provides parametric information, however are not semantically enriched. They provide parameters to elements but not the connection between them, not the relationship. It means that during a simulation Virtual Users can recognize the elements represented in BIM models, but not what they mean, due to the lack of semantics. At the same time the built environment may assume different functions depending on the physical configuration or activities that are performed on it. The status of the space may reveal differences and these changes occur constantly and are dynamic. In an initial state, a room can be noisy and a moment later, quiet. This can determine what type of activities the space can support according to each change in status. In this study we demonstrate how the spaces can express different semantic information according to the activity performed on it. The aim of this paper is to simulate the activities carried out in the building and how they can generate different semantics to spaces according to the use given to it. Then we analyze the conditions to the implementation of this knowledge in the BIM model.

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

title	Computational and Physical Modeling for Multi-Cellular Pneumatic Envelope Assemblies
source	International Journal of Architectural Computing vol. 13 - no. 2, 143-169
summary	This article describes recent research on the performative, formal and aesthetic potentials of multicellular pneumatic foil-based envelope systems for lightweight, responsive building skins able to control thermal insulation and air exchange with minimal amounts of energy and mechanical components. The prototype-based research involves the use of principles from biological examples of pneus, which inform the design of physical analogue models at an architectural scale. The process entails physical-computational feedback loops wherein physical performance findings are fed into computational design models for pneumatics and membranes, as well as modified energy models, in order to advance the predictive design capacities of simulation tools in designing such systems. In this process, material agency allies with computational agency to develop novel possibilities for dynamic pneumatic envelopes.

summary	This research paper describes the implementation of virtual reality immersive simulation studios in academia, facilitated by the use of the “Virtual Sketching Method” (VSM). The VSM allows the basic expression of architectural forms and the perceptual experience of interior and exterior spaces. It fosters simulations based on render-less (low resolution) visualization in contrast to other simulation workflows based on render-more (high resolution) visualization techniques. It bridges between different types of media and supports iterative cycles of formulation, prototyping, and assessment. The paper reports on students’ learning outcomes and their qualitative correlation with the VSM usability and effectiveness in design learning.

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	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	Research investigating water-driven passive actuation demonstrates the potential to transform how buildings interact with their environment while avoiding the complications of conventionally powered actuation. Previous experiments evidence the possibilities of bi-layer materials (Reichert, Menges, and Correa 2015; Correa et al. 2015) and mechanical assemblies with discretely connected actuating members (Gupta et al. 2019). By leveraging changes in weather to power actuated building components these projects explore the use of smart biomaterials and responsive building systems. Though promising the implementation of these technologies requires deep engagement into material synthesis and fabrication. This paper presents the design and prototyping of a rain responsive faÃ§ade system using chitosan hygroscopic films as actuators counterbalanced by programmed compliant mechanisms. Building on previous work into chitosan film assemblies this research focuses on the development of compliant mechanisms as a means of controlling movement without over-complicated rotating parts.

summary	Based on the premise that the form generation phase in the design of handicraft products is one of the most complexes, the article proposes the use of the "Roles of products and users expectations" model by Jacob-Dazarola (2015), and “Pre-inventive 2D and 3D forms” method based on Finke (1993). The methods are evidenced in a case study, in which five handicraft product projects were developed, based on the cultural identity of Guapi, a town in the Colombian Pacific.

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.

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.

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.

summary	We have developed a modular approach to the parametric design of a patterned façade for tropical climates, using a “lighter” data set and model that integrates a number of performance considerations. This modular approach separates the façade's design into form, façade pattern, façade density requirements, and façade components, and reintegrates these aspects via a triangular mesh, represented as a fast and convenient data structure based on half-edges. Through this separation, the design team can simultaneously work on the architectural appearance of the design, its performance, and its fabrication, while retaining holistic control through the constant reintegration of design changes via the half-edge data structure. In this way, we retain the advantages of a parametrically driven design process, such as automatic design generation and the integration of performance aspects, while permitting more flexible and non-sequential design explorations by different members of the design team.

summary	This paper describes a novel method for determining the capacity to generate solar energy integrated into the roofs of buildings by aerial survey using UAVs and BIM models for sizing the covering surfaces and integration of solar panels. Various digital procedures are enchained like planning of trajectories, image processing, geometric reconstitution, simulation of solar radiation and calculation of energy generation to promote on-site installation of clean energy sources in existing buildings, to ensure a more sustainable habitat.

title	Heuristic Optimization in Design

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.
