summary A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.

summary The paper proposes Parametric Systems Modeling (PSM) as a tool for building and city planning. The outlined method is based on the Systems Modeling Language (SysML) and is intended for design, dimensioning, and optimization of buildings and cities as systems. The approach exceeds the geometric approach, considers additional information from physics, technology, as well as biology, and provides a basis for multidisciplinary analyses and simulations. Its application aims at the exploration of innovative sustainable design solutions at system level. The proposal of an innovative buildinggreenhouse-city system serves to illustrate the approach. Features of this system are closed water cycles, renewable energy use, thermo-chemical energy storage and transport of energy for heating and cooling purposes on the base of desiccants, as well as recycling of CO2 , accumulation of biomass and related soil improvement.

title Design and Simulation of Textile Building Elements
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. 161-170
summary In this paper we examine the use of textile building elements and investigate on their potential scope of application in architecture. Other than commonly used for spanned or tent-like structures we concentrate on the use of textiles for folded, crinkled and procumbent assemblies, as these seem to correspond much better with the textiles´ inherent properties. On closer examination of these properties it becomes obvious that fabric primarily exists in a loose, uneven and irregular physicality that can be adjusted and configured into different states that match specific criteria. That is why fabric is mainly used for covering, protecting or hiding objects, e.g. as apparel for people. Only at a second glance does one recognize that textiles can be used for many other purposes such as collecting, separating, filtering or even healing. Thus, in the first instance of this research we examined customary usages and classified them into different categories that aided us to further develop practical application areas for the architectural domain. Subsequently to the fact that the shape of a textile might alter under the influence of forces, the further focus of this research lied on the appraisal of digital simulation techniques and simulation engines to provide sophisticated instruments for the generation of the associated time-based geometric form of the fabric. External elements that might drive this deformation process such as wind, temperature, precipitation, as well as static and dynamic building components were considered in the simulation process in order to generate visual output of the corresponding shapes. Studies about bipartite materials that can control the deformation process and might lead the textile beyond its primary functionality conclude this work.

title Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction
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. 151-158
summary Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

summary The paper presents a teaching experiment using the LOGO language to introduce geometric programming to architectural students with no a priory coding knowledge. Based on extreme simplicity as well as instant visual feedback, the language allows to introduce core programming concepts with little technicality. The extension of the language to a 3D space triggers designers interest and creativity while the introduction of a simple robotic drawing machine confront them with a simple fabrication context. These elements concur to develop a critical approach of the use of digital tools in the architectural design process, with the underlying aim to raise the students awareness on the implication of tooling on their design practice.

summary This paper gives insight into an ongoing funded research project dealing with architectural geometry and nonstandard fabrication methods. The innovative aspect of the project lies in the way it uses geometric ornamentation as a method to control the construction of double curved free-form surfaces out of planar building elements. After a short outline of the state of the art the paper gives an overview of the project’s novel constructive and esthetic approach to the planarization of curved forms, discusses the implications of the approach and presents some preliminary results.

title Mathematically Driven Forms and Digital Tectonic: A formula for realizing the digital

summary Mathematics has been the interest of architects for hundreds of years and has been used in projects ranging from the Denmark Pavilion at Expo 2010 to Gaudi’s cathedral. Generative form finding frequently takes the inspiration of the geometric aesthetic found in mathematic forms. Today, the influence of digital computation technology is increasingly evident in architectural form seeking and analysis as they relate to mathematics. The sculptural possibilities of math forms have reconditioned the design process that establishes new modeling and tectonic approaches. This paper focuses on the study of current constraints and new procedures within mathematical approaches to architecture. Furthermore, this paper describes three experimental projects exploring mathematically driven designs and their potential within architectural vocabulary. In these experiments, the designers and students explored the manipulation of a planar surface through algorithmic equations and the molecular make-up of a surface through voxel representation.

summary The use of digital fabrication in the discourse and education of architectural students has become a common skill in many schools of architecture. There is a growing demand for computer-aided design (CAD) skills, computer-aided manufacturing (CAM) logic, programming and fabrication knowledge in student education. The relevance of fabrication tools for architecture and design education goes beyond mere competence and can pursue innovation in what Branko Koleravic (2003) observed, “The digital age has radically reconfigured the relationship between conception and production, creating a direct digital link between what can be conceived and what can be built through “file-to-factory” processes of computer numerically controlled (CNC) fabrication”. However, there has been very little written about what students are actually learning through digital fabrication courses and the relevance of the skills required for innovation in the field of digital fabrication.

summary Since 2008 the preference for using different programming methods (Rhinoscript) had been analyzed using blogs. Searching for answers to explain the negative tendency of this year (from 48,063 to 16,332), a second repository was created (Grasshopper) featuring interactive methods and techniques. It has been discovered that of the five geographic regions analyzed Latin America is the only one that preferred the interactive interface (18% over programming). This shows that we are still keeping a strong dependency on the use of stable and safe technologies over disruptive ones that proved to be more efficient in design and fabrication.

summary The paper will be focussing on a number of digital design tools used in [our groups credentials]. A new laboratory called […] is developed with Virtual Reality for collaborative architectural design. A brief description of the systems and how they are used to support a design team is given. Synchronic and a-synchronic, local and inter-local communication is made possible. Methods for introducing sustainability in the digital design process and user participation over the Internet will be discussed. The results of the author’s PhD research “Collaborative architectural design in virtual reality” are used to develop a new approach in which team members use their own specific software. Swarm design applications developed in Virtools are used at the start of a project. The objects in the swarm can be urban and architectural functional volumes. Examples of the first are houses, offices, factories, roads and water ways. Examples of the second are working, dining, shopping and waiting spaces. Relations between the functional volumes with or without constraints make the functional volumes swarm to find equilibrium. Everything is dynamic, meaning that relations and functional volumes can change any time. Alternatives can be developed using different values for these parameters and by top-down intervention. When the final global layout has been chosen, using a criteria matrix with sustainability criteria to be judged by all participants, including the future users, a next phase is started amongst professionals using parametric design software. A study into different types of parametric design software makes clear why object parametric software can be used for IFC based BIM, while the more interesting process parametric software can not. To make this clear a pragmatic description of the IFC format is given with a simple example of such a file. Future research will be proposed in which applications of different disciplines are connected through the application programming interfaces, while integrating as much as possible the building information and knowledge in the IFC format.

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.

source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 117-125
summary Programming takes designers away from typical domain- and task-based interfaces such as three-dimensional modellers. It thus imposes additional cognitive load on the already challenging design task. Programming in the model is a system design strategy that embeds the act of programming in a 3D CAD model. This paper presents the argument for programming in the model and two user interface constructs that support such programming.

summary A design studio and a parallel research project focused on transformable fabric architecture. To facilitate a part of this work, computer based shape generation tools were used to optimize the placement of thin-film photovoltaic cells onto a transformable roof structure. In addition, the tension membrane fabric is rigged in a way that is similar to a sailing boat. The fabric is set into position by winches and cables. The winches are hand-operated so as to lower the overall energy cost. The initial computer models proceeded concurrently with the mockup of small-scale physical prototypes. In addition, the author used an open source programming language to implement a particle spring real time simulation of the fabric shapes. The simulation included a three-dimensional graphical representation of solar insolation and helped to further determine the physical geometry of the project. One of the goals was to evaluate whether larger transformations to the structure as a whole or smaller movements in the fabric would help to optimize the solar insolation benefits. As the examination of potential forms narrowed down to classical saddle shapes, the practical details of rigging the fabric imposed further limitations on its transformable nature. This paper is focused on how modeling with ad hoc tools and especially real-time computer simulation influenced the direction of the work.

summary Differently from other regions in the Planet, since 2010, in Latin America textual programming language (Rhinoscripting) is being replaced by its visual equivalent (Grasshopper). This is a consequence of our preference for an interactive platform, and because our design problems are not as complex, so we aim to control geometrical problems or aspects belonging to an product scale instead of an architectural one. Problems emerging when creating code could be improved by modifying and reusing existing solutions as a starting point, since learning would not be centered in the object but in the process of creating it, using a suitable instrument.

title Parametric Performative Systems: Designing a Bioclimatic Responsive Skin
source International Journal of Architectural Computing vol. 8 - no. 3, pp. 279-300
summary This paper assumes the façade as an innovative element of interaction between the inside and the outside: the architectural skin. As in nature, one of its most significant functions is the energy exchange with the environment. Similarly, efficiency increases by passive and active responses to climate conditions and site orientation. This research explores the potential of parametric techniques, programming and digital manufacturing, to design and build a Bioclimatic Responsive Skin (BRS). Firstly, we designed a bio-component applicable to any surface due to its parametric nature. Secondly, we fabricated two non-reactive working prototypes to study the manufacturing and construction details. Thirdly, we integrated the physical and the digital interfaces by using Generative Components™, Arduino, and Ubimash to generate a kinetic responsive model. This prototype was presented at SmartGeometry Workshop and Conference 2010. Finally, Lem3a architecture used this BRS in a real design project for a Sustainable house in New Hope, PA.

title Shaping building volumes through life cycle costs: a constraint programming approach for building volume optimisation
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 185-194
summary Due to a general freedom in the architectural design process, a wide range of possible alternatives exist; although building-volume designs must also continue to meet numerous, possibly conflicting design requirements originating from various related disciplines. This research addresses problems associated with missing quantitative design aids during the early design stages. It aims to provide designers with solutions that provide optimal cost-effectiveness. The demonstrated building-volume optimisation model minimises life cycle costs by determining optimal-volume dimensions, floor number, building orientation and ‘window / wall’ opening ratios while satisfying site and building code regulations and design constraints. Results indicate an optimal solution can be found within a practical timeframe. The proposed, novel approach to introduce cost objectives into building-volume design provides designers with a valuable decision support tool in a design domain that is known to be complex owing to multiple design criteria and constraint influences.

summary This paper is focusing on integrating footprint formations of buildingvolumes into an existing research of building-volume optimization (BVO). While earlier BVO experiments concentrated on single rectangular floor-area units per floor, the current BVO model allows footprint assemblies of combinatorial rectangular floor-area units per floor. The aspect of using these combinatorial floor assemblies is to provide more flexibility into the shaping of possible building-volumes and thus a more realistic approach to building-volume design. The investigation regarding combinatorial floor-area units concentrated on running time in reference to amount of allowable unit combinations per floor and the ability to provide close to optimal solutions through additional search runs. Results of the experiments documented a sharp increase of running time due to the additional allocation of floor-area units, while the BVO model was improved through the ability to generate combinatory footprint formation and offer close to optimal solutions.
