summary In order to achieve interactive architecture it is necessary to consider more than the technological components of sensors, controllers, and actuators. The interaction can be focused to different interaction activities: instructing, conversing, manipulating, and exploring (we propose to call this the interaction view). Additionally, the purpose of the building may range from performing, sustaining, servicing, symbolising, to entertaining (we propose to call this the world view). Combined, the interaction view and world view establish 20 different attitudes, which are flavours of behaviour for the interactive building. Through attitudes interaction profiles can be established and criteria derived for the design of interactive buildings.

title DesignScript: Scalable Tools for Design Computation

summary Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.

summary Visual rules are powerful in loosely capturing the impact of material behavior on form in designer’s hands-on experimentation. They present a first step to translate the causal relations between material and form to computation without sacrificing the uncertainties in the designer’s interaction with the materials. This study investigates how to model the relation between material and form with visual rules so that the model embodies some of the phenomenological aspects of reality, rather than merely reproducing it.

title Urban Body Mutations through the Use of the Network Configuration

summary Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.

summary Since the almost simultaneous publication of Kevin Lynch and Jane Jacobs´ seminal and pioneer urban manifestos, the discipline has been increasingly permeated by what could be rightly called the phenomenological impulse. While sharing methodological principles, however, they represent two very distinct approaches to the study of urban matters, a distinction rooted on their chosen object of study. The drawing of this distinction constitutes this research´s point of departure. Its fundamental aim is to help further the development of what we characterize as the Jacobs´s lineage of urban thought. To this end, the paper outlines methodological rudiments for the development of a methodological tool that would allow the beginning of a systematic study of the patterns of people´s presence and absence in urban space (streets). We call it Urban Polaroid. This work is part of a government funded (fondecyt 11110450) project.

summary This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

summary In this paper we explore the concept and design guidelines for an Autonomous Learning Oriented Proto System (ALOPS), a construction system designed to enhance its own performance through time. Our research has been focused on the fabrication of a prototype for a porous wall system which reacts to light intensities by closing or opening its apertures. Taking that aim, we used a combination of robotics, programing, and material behaviour to endow the system with the capacity to record reactions towards encountered sets of conditions during its active energy periods, allowing the system to use this knowledge database to evolve autonomously by feeding this information back into the computation process. This approach in construction systems opens up the architectural design processes to address the creation of digital memory structures rather than complex algorithms in order to operate specific functions. With this development, the architect could think of architectures constantly evolving by learning from their environments as well as of users forming symbiotic and behavioural bonds with the emergent spatial personalities, thus affecting the underpinning relationships between architecture, user and context.

title Measuring the Usability, Efficiency and Effectiveness of CAAD Tools and Applications
doi https://doi.org/10.52842/conf.ecaade.2013.1.147

summary Computer Aided Architectural Design (CAAD) decisions and judgments have been at the heart of architectural design practice. Despite the increasing popularity of computer aided design applications, measuring the decision making of designers empirically remains elusive. Past research claiming usefulness of the CAD has relied largely on anecdotal or case studies that are vulnerable to bias. The study reviews results of prior investigations. The relatively few laboratory experiments report hardly any empirical results regarding the measurement of CAD decision making. The study provides an overview of the literature of existing measurement methods that have been used in psychology and neuroscience to assess individual variations in design making, and highlight these different measurement methods’ strengths and weaknesses. We conclude with a comparative evaluation of the different measures and provide suggestions regarding their constructive use in building realistic theories of designer’s decision making measurement.

title Achieving Informed Decision-Making using Building Performance Simulation
doi https://doi.org/10.52842/conf.ecaade.2013.1.021
source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 1, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 21-30
summary Building performance simulation (BPS) is the basis for informed decision-making of Net Zero Energy Buildings (NZEBs) design. This paper aims to investigate the use of building performance simulation tools as a method of informing the design decision of NZEBs. The aim of this study is to evaluate the effect of a simulation-based decision aid, ZEBO, on informed decision-making using sensitivity analysis. The objective is to assess the effect of ZEBO and other building performance simulation (BPS) tools on three specific outcomes: (i) knowledge and satisfaction when using simulation for NZEB design; (ii) users’ decision-making attitudes and patterns, and (iii) performance robustness based on an energy analysis. The paper utilizes three design case studies comprising a framework to test the use of BPS tools. The paper provides results that shed light on the effectiveness of sensitivity analysis as an approach for informing the design decisions of NZEBs.

summary Agent-based systems have been widely investigated in simulation and modeling. In this paper, it is proposed that agent-based systems can also be developed as generative systems, in which different aspects of performative design can be defined as separate drivers in a proper computational framework. In this manner constrained generating procedures (CGP’s) are studied to integrate the discrete design processes into one system. Subsequently, this generative agent-based design tool is accompanied with generating and constraining mechanism which are informed by material characteristics and fabrication constraints, bringing to the forefront emergent complexity.

summary We present and discuss a didactic for augmenting architectural design education with computational design techniques via integrative feedback loops and show examples of student projects. Our goal is to embed new technical skills into existing design abilities as quickly as possible, in order to enable our students to exploit and explore the extended capabilities of digital design techniques within the framework of architectural design projects. We instigate a process of continuous mutual feedback between different fields: on the one hand between technique-based exercises and design-related steps, and on the other hand between the digital and the physical. Through oscillation and feedback, the newly learned skills are directly interwoven with the existing ones. Special emphasis is put on the illuminative effects of transitions between different media and on issues of fabrication.

The purpose of the tool is to extend limits of early design thinking. It uses fuzzy modeling techniques to adapt the ambiguous design phase. There are several commands in this digital tool to generate and modify layouts. Users can create, move, combine sketchy bubbles to form bigger footprints and see them in action dynamically. The tool offers a manual creation process.

summary “Frequency analysis of wood textures” presents the application of Fourier analysis to translate images of wood textures to the frequency domain. With this encoding, a lot more details can be captured by the same amount of data points than with other descriptions in the spatial domain. A small set of overlapping waves with different frequencies, magnitudes and phase angles allows to characterize the main features of the wood’s grain texture and to quantify and classify different samples. The sample’s color information is thereby enhanced with an array of direction vectors, describing the local orientation distribution.

summary Hyper-Morphology is an on-going research outlining a bottom-up evolutionary design process based on autonomous cellular building components. The research interfaces critical operational traits of the natural world (Evolutionary Development Biology, Embryology and Cellular Differentiation) with Evolutionary Computational techniques driven design methodologies. In the Hyper-Morphology research, genetic sequences are considered as sets of locally coded relational associations between multiple factors such as the amount of components, material based constraints, and geometric adaptation/degrees of freedom based adaptation abilities etc, which are embedded autonomously within each HyperCell component. Collective intelligence driven decision-making processes are intrinsic to the Hyper-Morphology logic for intelligently operating with autonomous componential systems (akin to swarm systems). This subsequently results in user and activity centric global morphology generation in real-time. Practically, the Hyper-Morphology research focuses on a 24/7 economy loop wherein real-time adaptive spatial usage interfaces with contemporary culture of flexible living within spatial constraints in a rapidly urbanizing world.

summary A method for quantifying ambient surveillance is presented, which is based on probabilistic-possibilistic perception. The human surveillance of a scene through observing camera sensed images on a monitor is modeled in three steps. First immersion of the observer is simulated by modeling perception of the scene from the camera locations using probabilistic perception approach. The perceptions are thereafter combined by means of probabilistic union, simulating simultaneous watching of the scene from multiple viewing positions. As third step the combined perceptions are converted to a possibility using triangular possibility density function. The latter step accounts for the fact that surveillance takes place via monitor depiction and not directly as perception of the actual physical scene. The method is described and demonstrated by means of an ambient surveillance application involving three cameras. The resulting possibility of perception is compared to the case of using two cameras, quantifying the added value of additional camera as to surveillance.
