title Making Sense of those Batteries and Wires: Parametric Design between Emergence and Autonomy
source The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 279-296.
summary This paper reports on the process and outcomes of a digital design studio that integrates parametric design and generative systems in architectural and urban design projects. It explores the interrelationship between the emergence of innovative formal representations using parametric design systems on the one hand, and design autonomy; more specifically the conscious process of generating and developing an architectural concept, on the other. Groups of undergraduate students working on an architectural project are asked to identify a specific conceptual parti that addresses an aspect of architectural quality, define strategies that satisfy those aspects, and computational methodologies to implement those strategies, such as rule-based systems, self-organization systems, and genetic algorithms. The paper describes the educational approach and studio outcomes, discusses implications for CAAD education and curricula, and addresses issues to be considered for parametric and generative software development.

summary This paper discusses the process of changing in the historical town – Baku in Azerbaijan in comparison to the achievements of European urban planners and architects (for example in: Paris, Vienna, Dublin). In Baku the fast and unlimited development and many investments in the public spaces have caused a lot of transformation not always to the better vision of the image of the city. At the same time, the development in some European cities is proceeding in other ways, preserving existing historical built environment.

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 The geometry of Chuck Hoberman as the basis for the development of dynamic experimental structures
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. 485.
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 Spatial Nets: the Computational and Material Study of Reticular Geometries
doi https://doi.org/10.52842/conf.acadia.2015.123
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. 123-135
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.

summary This paper has argued that interdisciplinary approach is necessary to get better understanding of the problem within a built heritage area. It is found that inhabitants perceived the mixed heritage architecture as their own, an appreciation also expressed toward perception values of building: uniqueness, aesthetic and age. The research has also shown that inhabitants in the Darmo residential area - Surabaya, Indonesia perceived that their area are worth to be conserve due to the function such as the city amenities and attribute of the shady environment. Taken together, these results suggest that a better understanding of inhabitant’s awareness will contribute to the successful conservation program.

summary In this study, we revisit the concepts of abstraction and materialization with regards to the theoretical framework of new materialism. Underlining the changing relationship between design through abstraction (DtA) and design through materialization (DtM) in design history, we propose an integration of the two towards achieving design emergence. Additional to a theoretical framework, we provide a showcase through material experiments of plaster and abstractions in the form of shape computation. We discuss results as parameters for future digital implementations and potentials for design practice and education.

summary The lack of urban planning has made the recreation areas increasingly smaller in the cities. Parks and squares gradually gave way to streets and avenues to try to accommodate the growing number of cars and motorcycles. An alternative that tries to balance recreation areas and urban roads was found in the city of San Francisco (USA). Parklets are temporary extensions of urban sidewalks that occupy a few parking spaces. This article aims to demonstrate the potential of parametric modeling in the development of parklets. Thus, anthropometric studies, amount of parking spaces and types of benches were used as input parameters. Rhinoceros and grasshopper programs were used for modeling, while 3D Studio Max was used for rendering. With this study it was possible to verify that when the project is parameterized the processes of creation and modification became faster, reducing design and implementation time.

title Re-inventing ceramic tiles: Using shape grammars as a generative method and the impact on design methodology

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

title Alternative Fabrication Process for Free-Form FRP Architectural Elements Relying on Fabric Materiality Towards Freedom from Molds and Surface Articulation
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. 397-410.
summary FRP (fiber reinforced polymers) is a family of composite materials combining fibers and polymers to offer exceptional mechanical properties. Its unique material properties have led to its wide application across industries. Although we witness a growing interest in the material in the architectural field in recent years, a significant barrier to its application lies in the need for a mold. The paper describes a new alternative fabrication process for architectural FRP elements that relies on fabric materiality. It suggests a mold free process, combining form finding and garment making techniques, to allow for complex morphologies, surface articulation and variation. The paper describes both the fabrication process through physical experiments, as well as the design process through the use of two design software tools. It demonstrates the potential for sustainable variation of large component facade system.

title Structural design based on performance applied to development of a lattice wind tower

summary This paper studies the process of parametric and algorithmic design, integrating structural analysis and design for the generation of complex geometric structures. This methodology is based on the Performative Model, where the shape is generated using performance criteria. In the approach, the development of complex structures is only possible by reversing the process of thinking to generate the form with established parameters for geometry, material and loading aspects. Thus, the structural engineer no longer only participates in the evaluation phase but also appears in the early stages, creating a process of exploration and production of common knowledge among architects and engineers. To research performance-based design, the development of a conceptual lattice for a wind tower is proposed. Thus, a system is made to generate geometries using Rhinoceros software, the Grasshopper plugin, and the VB programming language, integrated with stress analysis through the Scan & Solve plugin.

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 Nowadays, there is a growing interest in buildings' envelops presenting complex geometries and patterns. This interest is related with the use of new design tools, such as Generative Design, which promotes a greater design exploration. In this paper we discuss and illustrate a structured and systematic computational framework for the generation of facade designs. This framework includes (1) a classification of facades into different categories that we consider computationally relevant, and (2) an identification and implementation of a set of algorithms and strategies that address the needs of the different designs.

title The future of the architect’s employment: To which extent can architectural design be computerised?

summary This paper was motivated by Frey and Osborne’s [1] work about the probability of different occupations being computerised in the near future, titled “The Future of Employment”. In their study, the architect’s profession had a very low probability of being automated, which does not do justice to the past fifty years of research in the field of architectural design automation. After reviewing some concepts in economics and labor, and identifying three categories of tasks in regards to automation, we propose a new estimate, by looking independently at 30 architectural tasks. We also took into account the reported advances in the automation of these tasks through scientific research. We conclude that there is presently a change in skill requirements for architects, suggesting that we have to rethink architectural education, so architects will not need to compete against the computer in the near future.

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 Smart city and Internet of Things: possible changes in the public space

summary This work aims to investigate the concept of smart city within the Internet of Things (IoT), and analyses possible transformations of urban space in areas of surveillance and control. As already seen regularly in the media, surveillance and control of data on the internet is a problem that affects personal freedom. If similar surveillance system is applied in the Internet of Things, where people, objects and environments are interconnected, exchanging a huge volume of data, the problem substantially increases due the possibility of more control over various aspects of people's lives. The purpose of this paper is to do a critical reflection about the consequences of the smart city regarding the public space and privacy of the inhabitants.

summary The problem at hand is to ensure that the perception by means of Augmented Reality (AR) is hence reliable and opinions resulting from a Participatory Design (PD) mediated by this technology could be incorporated into the design solution. This paper presents the evaluation of multiple 3D models recognition in AR, with or without an auxiliary projection. Leisure area designs involve urban equipment of various dimensions that are visualized simultaneously. Therefore, it was necessary to verify if the participants were capable of recognizing them and which would be the best way to visualize: exclusively with the iPad screen or with the iPad associated with an external projection – to verify whether the visualization using an external projection would amplify the visualization area. The results obtained in the evaluation were used to improve the AR application and also, to develop guidelines for the AR use in a PD.

title Modulating Thermal Mass Behavior Through Surface Figuration

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.

summary In a built heritage process, meant as a structured system of activities aimed at the investigation, preservation, and management of architectural heritage, any task accomplished by the several actors involved in it is deeply influenced by the way the knowledge is represented and shared. In the current heritage practice, knowledge representation and management have shown several limitations due to the difficulty of dealing with large amount of extremely heterogeneous data. On this basis, this research aims at extending semantic web approaches and technologies to architectural heritage knowledge management in order to provide an integrated and multidisciplinary representation of the artifact and of the knowledge necessary to support any decision or any intervention and management activity. To this purpose, an ontology-based system, representing the knowledge related to the artifact and its contexts, has been developed through the formalization of domain-specific entities and relationships between them.
