summary	This research will explore and provide an initial study into the diversity of contemporary computational design methodologies emerging in the field of architecture. It will rely on modern philosophical and mathematical ideas as a resource to integrate a seemingly disparate set of design techniques into a unified framework for architectural design. The explorations in this paper will demonstrate a preliminary study into various methods of operating across this framework through a series of parametric design experiments that span across multiple scales. The result indicates new techniques and skills that are becoming increasingly important for architectural design.

summary	Folding strategies in architecture have been explored since the 1990s – if not before – as a method to generate spatial and structural concepts by applying complex geometries. These strategies are generally related to an analogue working method that involves paper folded models rather than digital form finding processes. Against this background the paper focuses on the impact and possibilities of folding principles from origami for the digital design process in using parametric software to generate integral and adaptive systems within an experimental and intuitive design approach.

title	Complexity, Digital Consciousness and Open Form: A New Design Paradigm

summary	Complexity as a result of improved design capabilities through the use of computer tools was introduced in the architectural debate since these became irreplaceable. On the other hand, not every designer is genuinely aware of the logical implications that the use of these tools may entail. Used as a simple emulation of enhanced traditional design tools—drawings and models, they do not alter the process of design significantly. However, the potential of such tools beyond their instrumentality introduces designers into the realm of digital consciousness. This paper analyzes complexity as an inherent quality of computer aided architectural design in relation to four different digitally conscious design strategies. First, the increase of complexity involved in digital architectural designs because of their potentiality to manage enormous amounts of differentiated information. Second, the complexity inherent to an open form such as parametric or generative designs may be defined. Third, the use of the computer as a smart partner involved in the design process —i.e., form finding strategies— rather than as a simple efficient machine able to repeat our abilities faster and more effectively in certain roles of the design process. Finally, it analyzes the possibility of generating parameterized typologies as a result of the openness of form, as well as the increased complexity that randomness may introduce in algorithmic design. The paper concludes with reflections on complexity vs. simplexity considering the fact that the simplicity characteristic of Modernism aesthetics and constructive values collide with the baroque formal complexity achieved in generative design.

summary	The imminent disruption of the modern paradigms of serialization, repetition and standardization, poses us a myriad of new questions regarding both the emerging aesthetics and the upcoming production means for a new architecture. Despite the canonic approach in which architects tend to invest, the public and private demand for mass housing production is increasing at an astonishing rate, requiring architects to rethink traditional— modern—strategies and to gain control over contemporary—digital—tools. This paper describes an academic research project focused on the implementation of such tools. Some related work is presented, emphasizing some of the approaches in parametric plan layout generation. And a case study is formulated in which the mass design of serially customized layouts is prepared to be solved through a beta plugin for Rhino – Grasshopper.

summary	The paper presents our experience and findings of teaching Building Information Modeling (BIM) at both the undergraduate and graduate levels. At the undergraduate level for Environmental Design students, basic BIM concept and modeling were exercised. At the graduate level for Ph.D. and MS students in Architecture, MArch students, and MS students in Construction Science, advanced topics including parametric design, database, Application Programming Interface (API), and building lifecycle applications of BIM were introduced. We suggest an incremental BIM skill development with a course agenda, for example: first year college – modeling; second year and third year – simulation and analysis for building systems; and fourth year and above until graduate level – customization. Detailed description of the courses, strategies, student projects, findings, and discussions are given in the paper.

doi	https://doi.org/10.52842/conf.acadia.2010.258
summary	This paper presents recent research for new mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on insect and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The proposed façade system uses integrated sensors and actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to manufacturing methods and material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli, and ultimately, effective performance of the whole system.

summary	It is perhaps no longer relevant to discuss digital tools purely as means in themselves; the growth of abstract systems or computational patterns for their own sake simply strain justification in light of real-world concerns such as climate change and economic crises. While growing concerns over climate change have necessitated an increased interest in sustainable urbanism and design, sustainability has done little to yet alter the morphological and typological consequences of architectural space (Hardy, 2008). In a series of overlapping research projects and design studio briefs, students, research assistants and we worked with the iterative and variable processes of Rhinoscript, McNeel’s Grasshopper and Bentley’s Generative Components to explore the possibilities of changing environmental extremes (specifically flooding) as catalysts for providing new urban morphologies and spatial organizations. Working between the master plan and the individual housing unit, we investigated arrays of terrace homes in the London Thames Valley flood zones while simultaneously exploring the potential for computational generation and parametric optimization.

title	Integrative Design Strategies for Multimedia in Architecture

summary	Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

summary	This paper introduces a JAVA based library for parametric modeling through programming. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depends on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations. We introduce key concepts of the library and show a use of the library within a form finding process driven by irradiance simulation.

summary	Several building works have demonstrated the possibilities of architectural design based on structural performance. This work discusses some examples and digital design strategies that approach this issue, as well as an exercise for a tower generated through topological optimization. That experience presents alternatives for a traditional office tower in Santiago, Chile, the Torre Santa Maria, based on generative design strategies for the incorporation of structural and environmental requirements to define parametric models. The experience and the capabilities studied reveal an intensive variation of architectural shape. This approach challenges conventional building regularity and suggests new ways of designing based on material performance.

summary	The purpose of this paper is to make apparent critical and theoretical aspects of the instrumentation of new technologies inside architectural processes. After twenty five years of “Choral Work” between architecture and post-structuralist philosophy superimposed together inside architectural processes, we now face a new technological era which seems to provide a new figure of authority by replacing logocentrism to mathematical logicocentrism. Everywhere, the “insemination” of computer by biogenetic algorithms and codification processes transform matter into a zoocentric paradigmatic system, which is supposed, by its internal “modulation,” to extend our potential of social dynamics into space. The goal of our demonstration will then be to examine new technical and theoretical strategies, in a way that the positivistic structure of computation can avoid a totalizing effect (that leading architecture under technological domination), but open up to an un-programmable (emergent) future far above “weaving” and calculated design.

summary	Computers are very common drawing tools in university design studios, but their potential as training tools in arts and design has not been explored in depth. Therefore, there is little understanding of how to incorporate digital and virtual media as learning tools in design studios. This paper describes the use of training programs in an experimental design course at the university level. This experiment was carried out as part of PhD research performed at the Faculty of Architecture and Arts at the Universidad de los Andes in Merida, Venezuela.

source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1077–1088
summary	This article aims to demonstrate how a theoretical-didactic model and its respective teaching strategies for algorithmic-parametric logic can act as potential elements of innovation in the architectural design process. Based on the theories of parametric design thinking by Oxman (2017) and the studies by Woodbury (2010) and Romcy (2017), such strategies are based on the principle that algorithmic logic can be understood, in certain circumstances, as a procedural framework and not just an instrumental one. It will also be discussed how the situation of remote learning in the face of the COVID-19 crisis brought about the use of virtual teaching tools as an increment of the learning process.

summary	The Solar Decathlon is an academic competition of houses powered exclusively by the sun. Around twenty university teams have been called on to build more sustainable and efficient solar houses. This paper presents some challenges of the design and construction process of the Brazilian team for the Solar Decathlon in Europe. The challenges focused on in this paper refer to the search for technologies and strategies for the creative integration and collaboration of more than 100 members from six universities and different research areas. Collaboration is one of the main objectives of the event and probably the greatest challenge among the participant teams.

summary	With the advent of Web 2.0 technologies, the Virtual Design Studio (VDS) has been revived in many schools of architecture around the globe. The recently evolving online Social Networks (SN) Platforms, as instruments for learning, have provided a potentially fruitful operative base for VDS. Yet these platforms have not enabled the VDS to explore new frontiers. All participants come from the same professional field and learn elements directly related to their existing design curriculum. The development of the VDS for interprofessional learning moves design education beyond conventional boundaries. The Interprofessional VDS (IPVDS) is an innovative method of teaching students from two different professional faculties the skills required for successful consultancy and promotional communication in the public realm. The IPVDS enabled students to develop consultancy skills and evidence-based communication strategies appropriate for disparate target audiences. It employed a digital SN learning platform to engage remotely-located students in acquiring new skills, transferring knowledge and achieving learning outcomes that enrich their professional experience. The paper presents details of the IPVDS, its methodology, outcomes, and evaluation of the studio, and discusses how the IPVDS is effective in enabling architectural students to understand and use communication and consultancy skills for collaboration across professional disciplines for the purpose of community engagement.

title	Open architectural design: an approach to managing complexity and uncertainty in an open design process
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 629-638

summary	By open exchange of ideas and artifacts and non apriori hierarchical processes, Open Strategies enable a better usage of distributed resources, and the release of more creative potential. Applying these Open Strategies to the architectural design process, is goal of our project. The technical basis for our research is FREAC, a software framework developed in-house which provides a collaboration space for co-operation between different users and tools. This framework is designed not just for exchanging the outcome of the design process but also for opening up the design process itself and making it more transparent. Such highly open and distributed design processes, however, also present new problems and uncertainties which need to be taken into account in order to reach successful design outcomes. As a result proposals for the management of such processes need to be developed that facilitate collaborative work but do not unnecessarily constrain the inherent complexity of the design process. The actor-network theory, and other different management concepts, provides a theoretical underpinning for our approach. The project is a collaboration between the fields of computer science in architecture and media management.

title	Situated Bioclimatic Information Design: a new approach to the processing and visualization of climate data
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 88-96
doi	https://doi.org/10.52842/conf.acadia.2010.088
summary	Currently, most approaches to graphic evaluative frameworks (GEFs) for the early-stage evaluation of bioclimatic design strategies adopt a design-tool metaphor, wherein a battery of analytical routines is performed by a software tool based upon a standardized weather file from which a stock set of graphic material is produced. In seeking to evaluate a broad range of climates and to address a wide variety of passive design strategies, existing climate visualization and evaluation tools position themselves far outside of the context of a situated design problem. Remaining agnostic to the particularities of site, program, tectonic system, and material behavior these tools become, by definition, generic. As a consequence, while such design-tools can be effective in evaluating particular relationships between environmental resource, demand profile, and built-system, they maintain a potential to be rendered ineffective in any outlying cases not specifically anticipated by their authors . Situated Bioclimatic Information Design (SBID) presents an alternative approach that targets a class of design strategies prominent among these outlying cases: those highly responsive to negotiation between the continually fluctuating resources within microclimates and the fluctuating demand profile of the building program. Using a custom-built weather data parser a number of diagrams and data visualizations have been produced under this approach. These visualizations are not only useful in and of themselves for aligning design strategies to specific contexts, but they also illustrate the foundations of a larger theoretical framework for the processing and visualization of climatic data for effective utilization of bioclimatic flows.

summary	The hierarchical organization of information is dominant in the setup of tectonic structures. In order to overcome the inherent limitations of these systems, self-organization is proposed as a means for future design. The paper exemplifies this within the research project “Lamel la Flock”. The research takes its point of departure in the structural abilities of the wooden Zollinger system: a traditional structural lamella system distributed as a woven pattern of interconnected beams. Where the original system has a very limited set of achievable geometries our research introduces an understanding of beam elements as autonomous entities with sensorymotor behaviour. By this means freeform structures can be achieved Through computation and methods of self-organization, the project investigates how to design and build with a system based on multiple and circular dependencies. Hereby the agent system negotiates between design intent, tectonic needs, and production. The project demonstrates how real-time interactive modeling can be hybridized with agent–based design strategies and how this environment can be linked to physical production. The use of knowledge embedded into the system as well as the flow of information between dynamic processes, Finite Element Calculation and machinery was key for linking the speculative with the physical.

title	Parametric Design of the Vela Roof
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 231-240
summary	Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

summary	The paper addresses the design of large roof structures for semi outdoor spaces through an investigation of a type of performance-oriented design, which aims at integrating performance evaluations in the early stages of the design process. Particularly, aiming at improving daylight and thermal comfort under large structures, the paper focuses on the exploration of passive solar strategies to reduce the need for imported energies. Referring to this context, the potential of parametric modeling is investigated with respect to performance-oriented design and a method, denoted ParaGen, is presented, based on the integration of parametric modeling and genetic algorithms. The potentials of the method are shown by discussing a case study, the roof SolSt. The design process of SolSt is based on parametric variations of its curvature, the density of its modules and the geometry of its cladding and explored based on the daylight and solar exposure of the covered spaces.
