summary	Voxelbeam explores precedents in the optimization of architectural structures, namely the Sydney Opera house Arup beam. The authors research three areas crucial to conceiving an innovative contemporary reinterpretation of the beam: A shift in structural analysis techniques from analytical to numerical models such as topology optimization, the fundamental differences between digital and analog representations of structural forces, and the translation of structural analysis data into methods for digital fabrication. The research aims to re-contextualize the structural beam within contemporary digital platforms, explores the architectural implications of topology optimization, and proposes two fabrication strategies based on the analysis results – including automated off-site pre-casting and multi-material 3d printing.

title	The next city and complex adaptive 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. 203.
summary	Urban futures are typically conceptualized as starting anew; an urban future is usually represented as a quest for an ideal state, replacing the status quo with visionary statement about ‘better’ futures. Repeatedly, propositions reinvent the way we live, work and play. The major urban innovations for the changing cityscape from the last 100 years, however, have opportunistically taken advantage of unprecedented technical developments in infrastructure rather than be drawn from architectural inventions in their right, such as telecommunications, services, utilities, point-to-point rapid transit including the elevator. Howard’s Garden City therefore presaged the suburb, just as Le Corbusier et al proposed the erasure of significant sections of inner city Barcelona and Paris to replace them with the newly contrived towers; the city reformed as the significantly more mobile and dense ‘Ville Radieuse’. More recently Masdar emerged from virgin sand and Milton Keynes from pristine pasture, serving as counterpoints to the paradigm of erasure and rebuild. Despite all these advances in technology and science, little has changed in the paradigm of urban form; the choices we have today are largely restricted to the suburban house or the apartment in the tower. Should the “next city” offer an alternative vision for the future, and what new design processes are required to realize the next city?

title	Pattern, cognition and spatial information processing: Representations of the spatial layout of architectural design with spatial-semantic analytics
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. 484.
summary	In this paper, we review and extend the idea of Alexander’s “pattern language”, especially from the viewpoints of complexity theories, information systems, and human-computer interaction, to explore spatial cognition-based design representations for “intelligent and adaptive/interactive environment” in architecture and urban planning. We propose a theoretic framework of design patterns “with spatial information processing”, and attempt to incorporate state-of-the-art computational methods of information visualization/visual analytics into the conventional CAAD approaches. Focused on the spatial-semantic analytics, together with abstract syntactic pattern representation, by using “spatial-semantic aware” graph grammar formalization, i.e., Spatial Graph Grammars (SGG), the relevant models, algorithms and tool are proposed. We testify our theoretic framework and computational tool VEGGIE (a Visual Environment of Graph Grammar Induction Engineering) by using actual architectural design works (spatial layout exemplars of a small office building and the three house projects by Frank Lloyd Wright) as study cases, so as to demonstrate our proposed approach for practical applications. The results are discussed and further research is suggested.

title	Lost in Translation: Towards an Automated Description of John Portman’s Domestic Architecture
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 657-661.
summary	The prevalent mode of shape grammar output is a two-dimensional drawing grammar. For architectural applications, these two- dimensional shape rules can hold a variety of interpretations in three-dimensional space. This work translates an existing grammar from a manual two-dimensional drawing grammar to an automated three-dimensional building grammar to explore the challenges and opportunities that this translation suggests in the larger context of shape computation. The case study considered here is a grammar interpreting John Portman’s architectural language as defined by the house Portman identifies as emblematic of his design principles, his 1964 personal residence Entelechy I.

summary	The new digital fabrication technologies are changing the production methods in contemporary society. The sharing of information, within a new logic of production, has the potential to change the current economic system. The present work look after the open source architecture for digital fabrication, through the constructive experience of House Magazine, developed by LAMO3d, Laboratory of 3d Models and Digital Fabrication on FAU-UFRJ. The project, sold in newsstands with the correspondent assembly instructions, aims to popularize the fabrication technologies by its absorption and transfiguration in popular culture. The open source projects and technologies promote the widening of uses of knowledge and technological advances, unlinking them from the big business and generating a dispersion of production. It is up to us to recognize its potential and shape its endless application possibilities.

doi	https://doi.org/10.52842/conf.ecaade.2015.1
summary	This is the first volume of the conference proceedings of the 33rd eCAADe conference, held from 16-18 September 2015 at TU Wien, Vienna, Austria. Both volumes together contain the 145 accepted papers that are also available digitally in CuminCAD (Cumulative Index of Computer Aided Architectural Design, http://cumincad.scix.net). The theme of the 33rd eCAADe conference is Real Time: Seeing architectural design as a time-critical and time-related activity requires new tools, methods and theories that deliver results not only accurately but also timely. As project cycles begin to accelerate, a variety of design decisions need to be taken swiftly and nevertheless accurately. Today's practice needs to explore the solution space through a rapid feedback loop between digital and physical products, used collaboratively and over a distance. To facilitate such a back-and-forth, geometries must be converted to manageable approximations on which intelligent tools can act, providing the designer with feedback and advice. This year's conference seeks to be a platform for research, teaching and practical work conducted in that spirit. The first volume of the proceedings contains 74 papers grouped under 19 sub-themes. Generally speaking, these are the formal contributions whereas volume 2 contains papers with a more educational or designerly background. This volume is furthermore preceded by keynote contributions summarising the positions of our invited speakers.

title	A model for sustainable site layout design of social housing with Pareto Genetic Algorithm: SSPM
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. 240.
summary	Nowadays as the aim to reduce the environmental impact of buildings becomes more apparent, a new architectural design approach is gaining momentum called sustainable architectural design. Sustainable architectural design process includes some regulations itself, which requires calculations, comparisons and consists of several possible conflicting objectives that need to be considered together. A successful green building design can be performed by the creation of alternative designs generated according to all the sustainability parameters and local regulations in conceptual design stage. As there are conflicting criteria's according to LEED and BREAM sustainable site parameters, local regulations and local climate conditions, an efficient decision support system can be developed by the help of Pareto based non-dominated genetic algorithm (NSGA-II) which is used for several possibly conflicting objectives that need to be considered together. In this paper, a model which aims to produce site layout alternatives according to sustainability criteria for cooperative apartment house complexes, will be mentioned.

title	Digital Design for Disassembly
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. 371-382

summary	The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.

title	Solar attic by parametric optimization and digital fabrication for NZE dwellings
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. 317-321.
summary	In order to support the usual enlargement of houses in developing countries and proper integration of renewable sources, this paper exposes a parametric design of attic with insulated timber boards and integrated solar panels. The proposal is based on urban map of solar potential available on-line (www.msc.ubiobio.cl), that for single houses suggest a solar attic customized to each dwelling shape and orientation, with industrialized timber construction elements. The calculation of optimal volume by house is developed with a multi-objective genetic algorithm (NSGA-II) and dynamic simulation, which provides different buildings alternatives with digital manufacturing.

summary	As the global population continues to climb and environmental conditions become further unpredictable, the creation of a more robust, intelligent, adaptable yet affordable housing system will become an evermore-significant issue. Existing housing typologies find themselves lagging behind other industries such as aerospace and even automotive, lacking advanced fabrication infrastructures as well as embedded intelligent technologies that could allow for: Global interconnectivity and or manipulation, automatic software/hardware updating and physical/computational adaptability. The use of advanced tools for manufacturing resembling industrial robotics, 3D printing and as well as intelligent fabrication systems currently remains nearly non-existent. Constructed using outdated design methodologies, materials and construction techniques, the current dwelling functions merely as an enclosure for life rather then an integrated system for information, comfort and commerce. This paper questions the current typology of “house” through the rethinking of not only form and material, but by reimagining the dwelling as a whole. Rather then observing the dwelling as a static form for infrastructural permanence, this paper redefines the home as a globalized commodity, which is both physically and technologically connected and adaptable.

wos	WOS:000372316000067
summary	This paper is focusing on the idea of error as the origin of difference in form but also as the path and the necessity for optimization. It describes the use of Cellular Automata (CA) for a series of structural and formal elements, whose proliferation is guided through sets of differential grids (multigrids) and leads to the buildup of big span structures and edifices as, for example, a cathedral. Starting from the error as the main idea/tool for optimization, taxonomies of morphological errors occur and at a next step, they are informed with contextual elements to produce an architectural system. A toolbox is composed that can be implemented in different scales and environmental parameters, providing variation, optimization, complexity and detail density. Different sets of experiments were created starting from linear structural elements and continuing to space dividers and larger surface components.

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	This paper studies the architectural potential of the implementation of material feedback using computer vision before and during an automated fabrication process. The combination of an industrial robot and a 3D camera is used expand the typical one-way design and fabrication process (from a digital design to a physical output), to a feedback loop, where specific material information becomes the main trigger of design decisions and fabrication processes. Several projects developed by the authors and tested during a robotic workshop aim to unveil different aspects of material feedback in architectural design, opening a discussion for the benefit and challenges of this new approach to design and fabrication.

summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

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	Reticular systems are in many aspects a distinct taxonomy of volumetric geometries. In comparison with the conventional embodiment of a ‘volume’ that encapsulates a certain quantity of space with a shell reticular geometries emerge from the accumulation of micro elements to define a gradient of space. Observed in biological systems, such structures result from their material properties and formation processes as well as often ‘simple’ axioms that produce complex results. In micro or macro levels, from forest tree canopies to plant cell walls these porous volumes are not shaped to have a singular ‘solution’ for a purpose; they provide the fundamental geometric characteristics of a ‘line cloud’ that is simultaneously flexible in response to its environment, porous to other systems (light, air, liquids) and less susceptible to critical damage. The porosity of such systems and their volumetric depth also result in kinetic spatial qualities in a 4D architectural space. Built upon a ‘weaving’ organization and the high performance material properties of carbon fiber composite, this research focuses on a formal grammar that initiates the complex system of a reticular volume. A finite ‘lexical’ axiom is consisted of the basic characters of H, M and L responding to the anchor points on the highest, medium and lower levels of the extruding loom. The genome thus produces a string of data that in the second phase of programming are assigned to 624 points on the loom. The code aims to distribute the nodes across the flat line cloud and organize the sequence for the purpose of overlapping the tensioned strings. The virtually infinite results are then assessed through an evolutionary solver for confining an array of favorable results that can be then selected from by the designer. This research focuses on an approximate control over the fundamental geometric characteristics of a reticular system such as node density and directionality. The proposal frames the favorable result of the weave to be three-dimensional and volumetric – avoiding distinctly linear or surface formations.

title	Fusing Conflicts Within Digital Heritage Through the Ambivalence of Gaming
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. 839-848

summary	Digital Heritage is amphibian by spanning between unreal-real (digital) and real-real (actual) environments. Or its amphiboly derives from a fact that relies not on contrasting realities but a hub from which an oscillation occurs between the real and the actual. Inferring to Baudrillard’s criticism of contemporary art, this paper presents these disparities and ambivalent conditions found in digital heritage by examining a full-dome media-art application called Look-Up. Touching upon the authenticity issue in cultural heritage, a design research project, Augmenting Kashgar, is then introduced on the basis of the claim that a design manner can fuse conflicts within Digital Heritage. Developed within the special context of Kashgar, China’s westernmost city, the methodology of the project that follows a Research through Design (RtD) approach is provided. Making use of the architectural features of Kashgar, designing a digital game as a counter-strategy to existing cultural heritage programmes is discussed with references to Baudrillard’s perspective on video games and gamers.
