summary Acoustic performance is defined by the parameter of reverberation time; however, this does not capture the acoustic experience in some types of open plan spaces. As many working and learning activities now take place in open plan spaces, it is important to be able to understand and design for the acoustic conditions of these spaces. This paper describes an experimental research project that studied the design processes necessary to design for sound. A responsive acoustic surface was designed, fabricated and tested. This acoustic surface was designed to create specific sonic effects. The design was simulated using custom integrated acoustic software and also using Odeon acoustic analysis software. The research demonstrates a method for designing space- and sound-defining surfaces, defines the concept of acoustic subspace, and suggests some new parameters for defining acoustic subspaces.

summary This paper presents a framework of study of an iterative evolution of a modular component designed in an attempt to simulate material constraints and motional response with the perspective to be multiplied into a dynamic system. The main scope of this project was to investigate the process that maps a territory of possibilities, among which lies the potential architectural solution. In order to explore this field a parametric model has been developed. The simulation of the materials nature has been embedded in the algorithm on a geometry constraint basis in an attempt to simulate the behavior of the system comprised by elements in tension and torsion. A multiplication process of the module was introduced at a following stage of the research focusing on regular tessellations and circle packing on the plane. Responsive performance has been studied on a selected specimen of the evolution given a hypothetic context scenario according to which the scale of the design was set at a façade component level. The resulting responsive permeable skin was presented as a potential design solution among the successive approximations of this algorithm. Along the course of the research the parametric tools were used not only as a medium of synchronous output visualization but also as a mechanism to simulate material properties, structural constrains, environmental data, and worked as stimuli of inspiration driving the overall design process.

summary The paper describes research developed with the aim of enquiring into the concepts of adaptability, transformation, and interactivity between the built space, its users and the surrounding environment to find appropriate responses to variations in spatial and functional needs, prompted by different uses and activities. After a look into the roots of kinetic architecture and a brief survey of the state of art, it presents the prototype of a responsive kinetic structure for a multi-purpose pavilion, concluding that by the integration of existing and emergent technologies, we now have the basic means to design and implement such structures.

summary As the architectural community becomes more and more “aware” of the ecological problems that our environment faces, digital tools gain a prominent position in the attempts to inform the design process with environmental sensibilities. However digital tools could provide more than the means to evaluate the energy efficiency of a design. The paper discusses the possible ‘digital-to-analogue’ design methodologies that are developed through the use of advanced computational techniques, alongside with material explorations, through example-projects designed and constructed by the students of the School of Architecture of the Aristotle University of Thessaloniki during an intensive, one week workshop.

summary The main topics of the conference are recognition, development and encouragement of virtual space design which in a consequence respect the problematic of sensitive and even fragile places of our physical and virtual surroundings. How do we define the levels of fragility either in physical or in virtual space, or in any fluid architectural endeavours? How do we respect the diversity of spatial fragility levels while introducing new design interventions? What can be defined as a (eCAADe-) sensitive / responsive / responsible design intervention? How to develop physical and virtual laboratories for sensitive / responsive / responsible design interventions? How to promote sensitive / responsive / responsible design interventions as members of eCAADe and related communities? What is the future of physical and virtual environments, requiring the most sensitive and responsible design interventions? These are just a few questions which were addressed at the eCAADe 2011 conference.

summary This paper discusses a collaborative project by RDAI architects, Bollinger+Grohmann and the timber construction company Holzbau Amann. The project is located in a former swimming pool in Paris and it is part of the new interior of a flagship store of the French fashion label Hermes. In late 2009, Rena Duma Architects, asked Bollinger+Grohmann to collaborate as structural engineers on a challenging design proposal within a very short timeframe. Three wooden lattice structures, the so-called “bulle” and one monumental staircase with a similar design approach characterize the interior of the new flagship store. The lattice structures are dividing the basement into different retail spaces. They vary in height (8-9 m) and diameter (8-12 m) and have a free-form shaped wicker basket appearance. Wood was the chosen material for these structures to strengthen the idea of the wickerbaskets and to create an interior space with a sustainable and innovative material.

summary Parametric modeling is a powerful tool to create variations of a design following specified criteria. Physical modeling provides flexible relationships between design elements and can simulate the behavior of hanging chain models. Building Information Modeling can contain geometry and design properties and relations. In this paper it is proposed to join all three to create a Simulation Design Tool that allows the intuitive creation of double curved surfaces which follow the rules of funicular systems. This tool is implemented in B-Processor, open-source Building Information Modeling software to bridge the break that occurs when moving from a design software package to Building Information Modeling. It is shown how the tool balances intuitive sculpting and accurate simulation and how the user can interact to mediate different design requirements.

summary To help architects in real life work it is needed to clarify what a building is from their point of view. Till now we have seen that building design aid programs are mainly conceived from an “external” perspective, that of computer scientists. Difficulties related to architectural design support programs result from: an insufficient overall model of the building; an inadequate formalization of information; an underestimated complexity inherent in the design process. To overcome these difficulties we introduce a ‘systemic’ building model that takes into account discipline-specific goals by means of relation structures to relate entities of domains and ontologies to formalize knowledge.

summary Today, right along with the products marketed and manufactured by the mass production techniques, continuously developing computing and technology have an undeniable impact on customized design, in which the users have a say on the products design and manufacturing. Mass customization is slowly settling down in architectural design concepts as well, like housing which is one of the best areas where users can reflect their living habits and preferences. In this study, user centric mass customization based model is developed, which creates housing floor plan combining the user-supplied data with the best possible creations generated by the genetic algorithms.

summary Computer technologies are used frequently and effectively in film-making. It is almost inevitable to exclude computer aid in different phases of the process such as video editing, compositing and generation of visual effects. Therefore, techniques and software used in this field are improving every day. In this paper, potentials of a technique known in film making industry as matchmoving will be elaborated to be used in architectural design process. The types of software available for matchmoving purposes excel at generating 3D environment data from video shots, making them very useful tools for architects.

summary Ambient displays allow physical space to be transformed into a dynamic and ever-changing environment in which boundaries are dissolved. However, it is likely that the incorporation of such digital elements affects people’s perception and understanding of space. In this particular study, a series of experiments were conducted to examine how a skewed perspective projection via an ambient display influences people’s navigation in public spaces. The findings are then presented showing how the participants’ responded to the presence of the skewed projection and the effects on the movement patterns. This study discusses the ability of an ambient display to influence navigation paths and suggests that a projection with skewed perspective can determine the creation of new movement patterns.

summary In architecture various approaches have been developed do deal with changing demands on the building. The most recent development is interactive architecture. In this paper we aim to outline what interactive architecture is. First we define the type of performance behavior that an interactive building or environment has. Following, we consider the relation between the system and the user. We derive four types of relations, characterized as “perfect butler,” “partner,” “environmental,” and “wizard.” Interactive systems are composed of sensors, controllers, actuators, and materials. Various degrees of interactivity can be achieved with such systems, ranging from passive, reactive, autonomous, to agent systems. Complete with earlier discussion of design methods this provides the range of aspects that should be considered when designing interactive architecture.

summary The issue of collaborative design has been elaborated extensively within the framework of previous CAAD–conferences. Today, an appreciation for traditional attitudes and methods can be observed, but interestingly, a mixture of approaches is also noticeable (computational techniques used in low–tech fabrication environments, for example). This allows for a round–table survey of the current state–of–the–art focused on experiences related to distant learning in the architectural curriculum. To make VDS viable, not only are technological solutions necessary, but so are social (among people) and professional (ways of behavior) ones. In this round–table we aim to identify critical factors of success (or failure).

summary As computational design processes have moved from representation to simulation, the focus has shifted towards advanced integration of performance as a form defining measure. Performance, though, is often assessed purely on the level of geometry and stratified between hierarchically independent layers. When looking at tension-active membrane systems, performance is integrated across multiple levels and with only the membrane material itself, defining the structural, spatial and atmospheric qualities. The research described in this paper investigates the integrative nature of this type of lightweight structure and proposes methodologies for generating highly articulated and differentiated systems. As material is a critical component, the research focuses on a system-based approach which places priority on the inclusion of material research and parameterization into a behavior-based computational process.

summary Performance as an architectural design paradigm has been emerging during the recent years. We have developed an understanding that we formalized as a taxonomy for performative architecture that considers performance from three points of view: health, safety and security performance; functional and efficiency performance; and psychological, social, cultural, and esthetic performance. This paper focuses on a design project that explores these ideas as a performative architecture proposal. The project focuses on the architectural transformation of the Defense Line of Amsterdam, 41 forts, as a green belt. This transformation considers a holistic approach of defining a general method and guideline. We developed a series of parametric models for the definition and generation of designs. The first model computes an urbanization level for each fort. Consequently, models are developed in 4 stages: regional design, urban design, building design, and production of a scale model, and these are applied in an iterative manner to reach design outcomes for the project.
