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.

title	Tactile models of elements of architectural heritage: from the building scale to the detail
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. 434-446.
summary	This paper describes the development of three-dimensional models, produced using digital fabrication techniques with the goal of providing a haptic experience of architectural heritage. These models were produced in three different representations: the building as a whole, elements and details. This study first undertakes a process of analysis and the formal decomposition of architectural components to identify basic or simplified elements which make it easier to understand the represented object by touching. The results obtained come from assessment tests of the tactile models as experienced by mainly blind individuals. Secondly, as part of this process, a method of constructing such models is defined. This study facilitates a greater understanding of the relationship between the represented objects (historic buildings) and the tactile models, and provides a technological and discursive basis for future implementation of tactile models in a specific context.

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	Assisted Construction of Non-Standard Wooden Walls and Envelope Structures by Parametric Modeling
doi	https://doi.org/10.52842/conf.caadria.2015.653
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. 653-662
summary	The non-standard approach, widely discussed in the past years as Architecture progressively uses alternative design methods different from the Euclidean paradigm, has allowed architects to transform the way architecture is conceived and materialized. Such evolution uses computer-aided design along with automation in production to originate the environment for the aided architectural conception field in which we present a method, in its early development stage, intended to create non-standard walls and envelopes based on cellular patterns using wood as base material. We present the results obtained from modeling and building two full-scale prototypes of non-standard wooden walls.

title	Informed Design to Robotic Production Systems - Developing Robotic 3D Printing System for Informed Material Deposition
doi	https://doi.org/10.52842/conf.ecaade.2015.2.287
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. 287-296
summary	This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architecture.

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.

title	Workshop: Developing Building Information Model Visualizations Using a Domain Specific Language
doi	https://doi.org/10.52842/conf.ecaade.2015.2.021

summary	The rise of digital building models has devalued the broad domain of architectural visualization, a former core topic of the domain. At the same time, digital media has opened up new possibilities for interactive and explorative visual representations. Against this background the workshop advocates to rediscover visualization as a distinct topic in the context of architecture and construction. The workshop introduces a method and a theoretic framework for the creation of visual representations from building information models under involvement of architects and engineers as domain experts, and a prototypical implementation, which serves as a proof of concept and allows for the practical application of the method. The workshop presents the prototype based on selected hands-on examples.

summary	The Processing language was created to teach programming to the design, architecture, and electronic arts communities. Despite its success, Processing has limited applicability in the architectural realm, as no CAD (Computer-Aided Design) or BIM (Building Information Modeling) application supports Processing. As a result, architects that have learnt Processing are unable to use the language in the context of modern, script-based, architectural work. This work joins Processing with the world of CAD or BIM applications, creating a solution that allows architects to prototype new designs using Processing and generate results in a CAD or BIM application. To achieve this, we developed an implementation of Processing for the Rosetta programming environment, allowing Processing scripts to generate 2D and 3D models in a variety of CAD or BIM applications, such as AutoCAD, Rhinoceros3D, SketchUp, and Revit.

summary	Within the architecture, engineering, and construction (AEC) industry, the application of multidisciplinary optimization methods has been shown to reach significant improvements in building performance compared to conventional design methods. As a result, the use of multidisciplinary optimization in the process of design is growing and becoming a common method that provides desired performance feedback for decision making. However, there is a lack of BIM-based multidisciplinary optimization tools that use the rich information stored in Building Information Models (BIM) to help designers explore design alternatives across multiple competing design criteria. In this paper we introduce Optimo, an open-source visual programming-based Multi-Objective Optimization (MOO) tool, which is developed to parametrically interact with Autodesk Revit for BIM-based optimization. The paper details the development process of Optimo and also provides the initial validation of its results using optimization test functions. Finally, strengths, limitations, current adoption by academia and industry, and future improvements of Optimo for building performance optimization are discussed.

summary	The protection and preservation of historical heritage are important tasks for all walks of life because rebuilding the exclusionary social memory, symbolically representing the nation’s identity. From this reflection, the problem arises of how to make the people appreciate the historic buildings. The Region of Medium High Uruguay, will serve as pilot study on a method of applying to the enhancement of national heritage by the population that is through the materialization of form. It is with the help of computer modeling combined with digital prototyping that seeks to find effective alternatives that use new technologies in the upgrading of historic buildings, a form of knowledge, integration and collaboration. In many areas of knowledge, consciousness makes the human being is connected to the world through all the senses. And touch, as experimentation and understanding of space it inhabits, may be the most overlooked sense in recent informatization times. In this research, the new realization techniques used to attempt to leverage awareness and understanding of a heritage, for a population hitherto alien to the cultural and historical values of a local architecture.

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.

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.

title	Analysing Populations of Design Variants Using Clustering and Archetypal Analysis
doi	https://doi.org/10.52842/conf.ecaade.2015.1.251
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 251-260
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	Multi-objective Optimisation of Building Geometry for Energy Consumption and View Quality
doi	https://doi.org/10.52842/conf.ecaade.2015.1.287

summary	In property development, the view quality contributes significantly to the property value. In many cases, the architect is constrained by the property developer to take full advantage of the view by designing large glazed facades ignoring the consequence on the energy consumption of the building caused by the conflicting orientation of the view. This paper presents a design tool to help the architect interactively explore different building and window geometries that trade-off energy consumption (kWh) and view quality (€). This design tool allows interaction with parametric building geometry, simulation of energy consumption and view quality, and an optimisation search engine. The simulation of the view quality quantifies a view according to the visibility and quality of its contents by using a novel view-scoring method. The design tool is tested with both north-oriented and south-oriented views and produces a Pareto front from which resulting geometries are visualised.

summary	Modeling the fragmented and heavily eroded remains of early temple architecture poses several challenges in accurate reconstruction of shape and form from digitally acquired datasets. This paper describes a collection of stepwise ad-hoc modeling methods that can re-assemble ambiguous and fragmentary evidence to provide a robust and empirical platform for the reconstruction of ruined temples. The paper presents the results of the method and the degree of accuracy and ambiguity in the acquisition, processing and reconstruction phases. A key aspect of the method is the maintenance of multiple “ground truths” from plural sources of partial evidence. Key findings of the paper demonstrate early results from the manipulation of geometric modeling primitives based on point collections, an advance in extending the classical tools of architectural analysis and comparison. The problem of accuracy and ambiguity in these methods and their algorithmic implementation is the subject of further investigation.

title	Analysis of Space Layout Using Attraction Force Model and Quadratic Assignment Problem
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. 247-267.
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.
