title	Transient Thermal Exchange and Developmental Form for Tactile Surfaces
doi	https://doi.org/10.52842/conf.acadia.2015.431
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 431-441
summary	The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.

title	Heuristic Optimization in Design

source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 357-369
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.

summary	EMOVERE, interdisciplinary project that aims at creating innovative interactive performance, brings together dance, sound and image. Bio-data related to emotions, heart and respiratory rate, are mediated by dancers and gives them control over music and video- mapping on stage. A creative process occurs through successive approaches, where technical possibilities are systematically explored until controlled, then body expression is lead by Alba Emoting, building an artistic discourse. Video-mapping is used for lighting purposes, creating a visual atmosphere for dancers. Fusion of media on stage creates synesthetic scenery where physical and digital aspects combine and interact in a codependent relationship.

title	Digital Fabrication Methods of Composite Architectural Panels for Complex Shaped Buildings
doi	https://doi.org/10.52842/conf.caadria.2015.703
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. 703-712
summary	Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most developments started outside the realm of architecture such as automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of this new technology. In this paper, the authors introduce preliminary results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This research examined the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a containerized facility for on-site panel production. Experiments focused on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, methods, assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.

title	Dynamic façades and computation: Towards an inclusive categorization of high performance kinetic façade systems
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. 243.
summary	This chapter provides a panorama of the current state of computationally controlled dynamic facades through a literature review and a survey of contemporary projects. This was completed with an underlying interest in understanding how innovative design solutions with the capacity to ‘react to’ and/or ‘interact with’ the varying states of climatic conditions have been developed. An analysis of these projects was conducted, and led to the identification of tendencies, which were subsequently synthesized and articulated. While most classifications are limited to describing the movement or structure needed to achieve morphological transformation, an important recommendation is to also consider control as a determining factor. For this reason, the culmination of the investigation presented here is a proposal for a classification structure of dynamic facades, developed according to the functional modus operandi of each structure in terms of movement and control.

title	Real-Time Multi-Zone Building Performance Impacts of Occupant Interaction with Dynamic Façade Systems
doi	https://doi.org/10.52842/conf.ecaade.2015.2.669
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. 669-678
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.

title	The Cave Is the Campfire: Thermal Forms in Architecture
doi	https://doi.org/10.52842/conf.acadia.2015.395

summary	The thermal categories established by Reyner Banham are useful for identifying historical points at which structure is "liberated" from the task of being the prime controller of the environment, as well as identifying the impact on design culture, which given the freedom to invest structure with a high degree of sculptural plasticity, exaggerated the disconnect between form and thermal performance, resulting in a situation in which form is inherently viewed as incapable of performing work equivalent to mechanical systems.

summary	Since 1985 the Computer-Aided Architectural Design Futures Foundation has fostered high level discussions about the search for excellence in the built environment through the use of new technologies with an exploratory and critical perspective. In 2015, the 16th CAAD Futures Conference was held, for the first time, in South America, in the lively megalopolis of Sao Paulo, Brazil. In order to establish a connection to local issues, the theme of the conference was "The next city". The city of Sao Paulo was torn down and almost completely rebuilt twice, from the mid 1800s to the mid 1900s, evolving from a city built in rammed-earth to a city built in bricks and then from a city built in bricks to a city built in concrete. In the 21st century, with the widespread use of digital technologies both in the design and production of buildings, cities are changing even faster, in terms of layout, materials, shapes, textures, production methods and, above all, in terms of the information that is now embedded in built systems.Among the 200 abstracts received in the first phase, 64 were selected for presentation in the conference and publication in the Electronic Proceedings, either as long or short papers, after 3 tough evaluation stages. Each paper was reviewed by at least three different experts from an international committee of more than 80 highly experienced researchers. The authors come from 23 different countries. Among all papers, 10 come from Latin-American institutions, which have been usually under-represented in CAAD Futures. The 33 highest rated long papers are also being published in a printed book by Springer. For this reason, only their abstracts were included in this Electronic Proceedings, at the end of each chapter.The papers in this book have been organized under the following topics: (1) modeling, analyzing and simulating the city, (2) sustainability and performance of the built environment, (3) automated and parametric design, (4) building information modeling (BIM), (5) fabrication and materiality, and (6) shape studies. The first topic includes papers describing different uses of computation applied to the study of the urban environment. The second one represents one of the most important current issues in the study and design of the built environment. The third topic, automated and parametric design, is an established field of research that is finally becoming more available to practitioners. Fabrication has been a hot topic in CAAD conferences, and is becoming ever more popular. This new way of making design and buildings will soon start affecting the way cities look like. Finally, shape studies are an established and respected field in design computing that is traditionally discussed in CAAD conferences.

title	C-Lith: Carbon Fiber Architectural Units
doi	https://doi.org/10.52842/conf.acadia.2015.069
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 69-79
summary	C-LITH is the reconsideration of the architectural building unit through the exploration of new composite techniques and materials. Our project develops individual compo- nents that exploit the strength, lightness, and variability possible with carbon ber laments when paired with computation, digital fabrication, and hand assembly. Traditionally, architectural units made of brick or concrete are small and multiple, heavy, dif cult to vary, and are much better in compression than tension. Using carbon ber laments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, developed through winding pre-preg carbon ber tow around disposable molds, bene t structurally from the quasi-isotropic properties that are developed through the winding patterns. The specific structural capacities of the units remain to be understood through further testing and analysis, which falls outside the scope of this current research. At this junction, structural capacities have been determined empirically, i.e. will it stand? Most importantly, as a formal study, our units address the use of carbon ber at the scale of architectural production. A majority of the effort involved in materializing C-LITH was the development of a two-fold prototypical manufacturing process that produces the components and assembly. For this we invented a method to quickly and cheaply construct variable cardboard molds that could withstand the wound casting and baking steps, but could also be easily weakened through water immersion to be removed. For the assembly we developed a rigid dummy-jig system to hold the joint plates in position with a high level of precision but could also incrementally absorb the adjustment errors unavoidable in hand assembly systems. Using a simple pin connection the resultant structures can be easily disassembled for transportation and reassembly elsewhere.

title	Data Mapping and Ornament in Digital Craft

summary	With an ever-increasing index of digital artifacts, we have begun to exhaust variation as an adaptive technique. The problem with incremental modulation (here understood as sequential and slowly progressing change of a set of parameters within a field condition) is that in essence it leads to morphologically equivalent and, hence, repetitive patterns of habitation. While the role of variation proved key in pushing forward an essential body of research testing and optimizing principles of mass customization, its residual effects become critically disconcerting. This paper presents an investigation of tectonic mutations for the generation of form, seen through data simulation experiments and machining artifacts. Through several projects we investigate the effects of ornament created as a result of the new relationship between generative modeling, simulation, and fabrication in the digital age. Subject to (de)generative mutation techniques, ornament can be under-stood as a result of overlaid data, whether the data is performance related or not, in both massing and surface conditions. This new working methodology will mitigate between the incertitude regarding time, history and memory, and by reinventing their relation it will reassess ornament’s agency within the digital culture. Design methods are extended by exploring, collecting, analyzing, and representing data through various materialization processes. Design is therefore reconsidered as being injected with the concepts of data driven design and dependent on the inter-play between performance and aesthetics. In this way, we consider the footprint - or the subsequent impact - of the human onto the nonhuman using artificial intelligence as a medium. These intentionally or accidentally engraved layers of information begin to describe potential trajectories of novel survival modes in the Anthropocene.

title	Design Methods for Large Scale Printing

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. 331-339
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.

title	Gradient Transparency: Marine Animals As a Source of Inspiration. - Exploring Material Bio-Mimicry through the Latest 3D Printing Technology in Architectural surfaces
doi	https://doi.org/10.52842/conf.ecaade.2015.2.325
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. 325-330
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	Transient Materialization: Ephemeral, Material-Oriented Digital Fabrication
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. 411-420.
summary	This paper introduces the notion of transient materialization through an exploration of the relationship between digital and material-based digital fabrication. The research was inspired by direct observations of nature’s beauty in the form of thin films. The building block of the experiment is an n-hedron structure composed mainly of soap foam, which is blown into a foam structure. The paper questions this structure’s materiality, examines its physical performance and ephemeral characteristics, and expands on its meaning through an experiment in digital fabrication. Specifically, this experiment demonstrates various configurations of dynamic and programmable foam structures on a large scale of fabrication. The fabrication interacts with the algorithm, which involves a mixture of air and helium (controlled by pneumatic valves), as well as additive chemical substances and thickening agents, all of which exist in a certain space and time.

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.

title	Mass Regimes: Geometric Actuation of Thermal Behavior
source	International Journal of Architectural Computing vol. 13 - no. 2, 169-194
summary	The Mass Regimes is a research project that investigates the effect of complex geometry on processes of passive heat distribution in thermal mass systems. In the context of systems thinking, this research intends to instrumentalize design principles that engage a wider range of design tactics for choreographing thermal gradients between buildings and their environment. Research for this project has brought about a deeper understanding of how specific geometric manipulations of surface area over the same mass (Figure 1) affect the rate of thermal transfer. Leveraging physical simulations of geometric populations, along with current computational and design tools, the project sheds light on performative trends that may enhance creative design explorations in the use of passive systems. Preliminary analysis of varied geometric populations suggest an exciting trend and the possibility for a more synthetic incorporation of morphology, one in which surface geometry can be passively utilized to generate effects with more fidelity over the pace of thermal absorption and the release of sensible heat.

title	Modulating Thermal Mass Behavior Through Surface Figuration

source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

title	Dialogue between Building Shape and Thermal Performance
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 174-179
summary	This paper deals with the research of the building shape in a constant and dialectical relationship with thermal performance. The purpose of this research is to understand and explore the dialogue between shape and performance with generative strategies. The method was based on the works by Oxman (2010), Olgyay (2015), and Di Mari & Yoo (2012), by means that relate the form to performance issues. The thermal performance data found to result from the relationship between thermal conditions, the shape of the envelope, and the characteristics of the eight Brazilian bioclimatic zones.

title	BIM for thermal performance analysis in Minha Casa Minha Vida Program buildings
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 25-29.
summary	The Minha Casa Minha Vida institutional housing program aims to build millions of residences in Brazilian cities. This situation decreases the building quality as the Federal Government, who founds the program, demands very low costs, so it is even more complicate to achieve quality enhancement. To solve this situation, many regulations have been instituted and, in 2013, ABNT published NBR 15575, a regulation regarding housing building performance, including aspects such as thermal, acoustic and maintenance performance. This paper aims to study thermal analysis section and the possibility to use BIM to achieve accurate data about thermal performance.

summary	This work is part of a research on decision-making processes in architecture involving computer programs in the early stages of designing the building envelope. The research involves two steps: (1) intuitive processes analysis during the handling of the building envelope components - floor, roof, walls, windows, solar protection elements - and (2) generative processes analysis of building envelopes supported by performance models. This article is the first step, analyzing four housing prototypes, designed and built for the Solar Decathlon competition. First, the building envelope elements and thermal characteristics of these prototypes were modeled; then different materials that make up the envelope were tested, aimed at assessing thermal performance against the modifications proposed in six different scenarios. The results showed that it is possible to obtain intuitive solutions that equalize temperature changes in the early stages of design with computing environments even without the use of detailed data on the characteristics of buildings, features of the later stages of the project.

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.
