title Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 109-118
summary This paper outlines an approach to adaptive residential design explored through recent research and an executed prototype, the North House project (2007-2009), undertaken through an interdisciplinary collaboration of researchers and students from the University of Waterloo, Ryerson University and Simon Fraser University in concert with professional and industry partners. This project aimed to develop a framework for the delivery of adaptive detached residential buildings capable of net-zero energy performance in the temperate climate zone, or the near north. Within this project, the term “adaptive” is developed across several tracts of conceptualization and execution including site and climatically derived models for building material composition and envelope ratios, environmentally-responsive kinetic envelope components, intelligent HVAC controls and interactive interface design aimed at producing co-evolutionary behaviors between building systems and inhabitants. A provisional definition of adaptive architecture is outlined to address this range of considerations that calls into question the stable image of domestic architecture and its relationship to energy and contemporary assumptions regarding sustainable design. This paper also outlines computational approaches to design optimization, distributed building systems integration and the human-controls interfaces applicable to the home’s ecology of physical and information technologies.

title Animation vs. Simulation
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 803-808
summary In his book “Cinema as an Art”, Rudolf Arnheim states that cinema (art) cannot achieve to realize the mechanical reproduction of the real (nature) because of technical limitations but also states that these limitations are compulsory for the production of art. According to Arnheim, these limitations cause artists to interpret the real (nature) and to materialize impressive expressions. Architecture presents its productions to its viewers (customers) using some kind of media, before materializing them in the physical world. The most common ones nowadays are technical drawings (perspectives), models, photographs and computer aided models and animations. The architect makes impressive expressions based on the technical limitations of the medium he/she uses. With the computer technology, simulation gives possibilities to the architect for presenting and experiencing his/her art very close to reality. Simulation is the best way to reproduce the reality mechanically, when it is compared to other mediums. In this study, simulation’s potential as an architectural presentation technique is examined through Arnheim’s vision and Rembrandt’s painting “Staalmeesters”.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.797-804
summary “A city can not be designed” Watanabe [1]: our ambition can be at the maximum to guide someway and in some part its growth. So as planners need tools to aid an open design with uncertain goals. This research group beginto develop such a tool at high level of abstraction (Fioravanti 2008), with theaim of investigating the potentiality of a collaboration among complementary research domains. The present work reports about early implementation results of an innovative approach developed by the authors, for representation of design knowledge. It has been identified in the Urban Design Ontology (Montenegro and Duarte 2009) some design entities and their internal relationships that have been formalized and visualized by means of an intuitive interface. As a matter of fact, this approach, by means of inference engines allows coherence’s check and constraint verification, pointing out incompatibility between initial design program and each partial specialist design solution and/or the overall shared one.

title Methodology for Ideation of Interaction Design
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 371-380
summary This paper explores new methodology, tools, and techniques for ideation of interaction design. On one hand, our work takes a mixed approach to developing design methodology by integrating usability tests and ethnographic studies in the ideation process. On the other hand, parallel design with user participation is attempted to reduce interactive design life cycle. An interaction design example is drawn from i-Awn project, an activity-coordination and reminding system in smart homes. This example demonstrates our mixed approach and shows how a new methodology is developed for validating the quality of user experience in a critical process of designing. The objective is to get the right interaction and the interaction right, provoking new ways of thinking about usability evaluation in the ideation process. The social, cultural and emotional uses of interactive systems in smart homes are discussed.

summary We propose and describe a working computer implementation for shape grammars that handles embedding relations in two dimensional shapes. The technical framework proposed explores a graph data structure to temporarily represent boundary elements of shapes and how they are assembled. With the associated algorithms, this structure enables a systematic search for parts. The employment of user defined constraints allows for an interactive search. In accordance with the continuous character of shapes, the study puts forth a practical part detection method, which extends to non-deterministic cases.

title Role of Studio Exercises in Digital Design Education: Case Study of the Nine-Square Grid
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 145-152
summary This paper is about short term and contextually limited kit-of-parts exercises in architectural education. Studio exercises are one of the key educational tools in architecture, which should be reconsidered with the developing technologies. As design computing becomes the mainstream thinking in architecture, the need for not only renewed studio exercises but for new educational frameworks becomes an essential issue. Thus, in this paper we will be proposing a different perspective on digital studio education, by explaining the fundamentals of studio exercises and their digital transformation potentials. Our experience with one of the most common kit-of-parts exercises, the nine-square grid, as a computational design problem for the first year students will be presented here as a part of this on going study.

title Virtual Ampang Jaya: An interactive visualization environment for modeling urban growth and spatio-temporal transformation
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 379-394
summary Virtual Ampang Jaya is an interactive visualization environment for modeling urban growth and spatio-temporal transformation to expose and evaluate the different layers of Ampang Jaya, consisting of social, economic, built and natural environments. The research will investigate the techniques of data acquisition, data reconstruction from physical to digital, urban analysis and visualization in constructing a digital model which may include low geometric content such as 2D digital maps and digital orthographics to high geometric content such as full volumetric parametric modeling. The process will integrate the state of the art GIS system to explore GIS powerful analytical and querying capabilities with interactive visualization environment as well as test the model as a predictive tool. The model will set as an experimental test pad in providing a new platform to support decision making about the spatial growth of Ampang Jaya by the various stakeholders in the planning processes. Such an environment will improve the subsequent digital models and research in the area of urban design and planning where visual communication is central.

title Architectural design analysis, historical reconstruction and structured archival using 3D models: Techniques, methodology and long term preservation of digital models
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 119-132
summary With the increased usage of 3D modeling, visualization, simulation and Building Information Modeling, architects produce 3D models, both for new designs and for historic reconstructions. However, these models are seldom shared to transfer structured information about the project. Even if they are exchanged, they are often not usable outside of their original design application. Additionally, digital archives with architectural content can not easily provide structured information about these 3D models, limiting their usefulness. This article discusses an approach to provide better structured models, using a combination of a sound methodology, the application of open file formats and additional metadata creation.

title Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

summary The base of informal urban settlements (slums) is housing, basic urban cell with both habitation and productive functions - tertiary, social and environmental. Intermediate spaces between housing and the city (the ground floor and the free space between the house and the street) become mediating mechanism between the individual and collective life, hence, urban tissue catalysts. New technologies get inserted in this intermediate scale through locutorios (premise offering public telephones and Internet connection), key spaces in social life.This scale between the house and the city allows proximity, accessibility, appropriation and identity, and shows rhe capacity of intermediate scale to absorve urban transformations.

title How much is it? About the use of the element method in conjunction with optimization techniques
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 5-15
summary It is obvious that the preparation and compliance with cost estimates for a proposed architectural design is indispensable for successful realization of building projects. A variety of methods exists that can be used by the architect to achieve this objective. However, most of these methods are regularly not used until the design is completed. In many cases this procedure leads to cost overruns. Hence, our paradigm is to estimate the total building costs prior to the generation of detailed designs and thus use the costs of building elements as design parameters right from the beginning to produce design solutions which entail the least possible costs. For this purpose we invert the customary process through the use of building element costs as a means for the automatic generation of monetarily assessable design solutions. For various reasons we concentrate on the design of housing projects. The methodology however, can be adopted to any other kind of building typology.

title Programmatic Formation: Practical Applications of Parametric Design
source International Journal of Architectural Computing vol. 7 - no. 4, 587-604
summary Programmatic Formation explores design as a responsive process. The study we present engages the complexity of the surroundings using parametric and generative design methods. It illustrates that responsiveness of designs can be achieved beyond geometric explorations. The parametric models can combine and respond simultaneously to design and its programmatic factors, such as performance-sensitive design-decisions, and constraints. We demonstrate this through a series of case studies for a housing tower. The studies explore the extent to which non-spatial parameters can be incorporated into spatial parametric dependencies in design. The results apply digital design and modeling, common to the curriculum of architecture schools, to the practical realm of building design and city planning. While practitioners are often slow to include contemporary design and planning methods into their daily work, the research illustrates how the incorporation of skills and knowledge acquired as part of university education can be effectively incorporated into everyday design and planning.

summary The study reports an application of VR models in the assessment of a part of physical planning project. The project outputs were different reports, GIS data and maps, and CAD drawings. The GIS data were used to create the VR models by importing Shpfiles of the GIS project outputs to VR software. The study presents VR models and the assessment of the physical planning project in terms of: 1) effect of the population increase, 2) effect of the required residential units, and 3) quality assurance for the current situation and future situation. The method used to build up the VR Models was through satellite images (by Google Earth Pro) and VR software (by UC Win/Road). Different models were built up to visualize and assess the alternative solutions and various influential factors. The study employed Virtual Reality in various urban and planning problems through models that are employed as tools of communication and design. The visualized environment and the associated models facilitated the evaluation of important areas, namely: impact of different factors and alternative solutions. The study concludes that the processes, such as decision making, visualization and representation, performed through VR manifest its importance to different design phases of urban and physical planning.

summary What sort of interfaces will allow, in the future, to manage the evolution of information and knowledge generation? What new scenarios would emerge in contemporary architecture when the access to a multidimensional architectural database is open and it is written and visited by anyone, anywhere in earth? Internet evolution is fast and unpredictable, propelling deep changes at different levels of our society. Spinoffs, unexpected outcomes are result of those changes, unfolding uncertain, unstable scenarios. This paper discusses the question of what could be the way to organize the process of registering, documenting and online publishing, native digital, three-dimensional content of Architecture, assuming the critical issue of information integration.

summary The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

summary This paper argues that familiarity is the tool that enables the understanding of space abstraction and representation. Familiarity in this context is independent from embodied interaction, and is crudely based on the connection between the various similar images of space; in this particular case, virtual space. Our investigation into the nature of human interaction with space, its abstraction and its representation is based on the critical contrast between the outcomes of interaction with two virtual versions of a physical reality; the first version is a non-linear interactive graphical abstraction of the space where no assertions or indicators are given as to whether or not there is a relationship between the abstraction and its physical reality, whereas the second is a none-linear interactive 3D virtual environment clearly representing the physical space in question. The paper utilises qualitative methods of investigation in order to gain an insight into human embodied experience in space, its abstraction and representation.

summary “Digital city” is a copy of an actual city in the virtual space. It is expected to play an important role in urban planning, disaster simulation etc. Recent advanced remote sensing technologies, which are capable to quickly provide detailed information of city areas, ease the construction of 3D city models. Urbanization has evinced interest from a wide section of the society including experts, amateurs and novices. With the development and infrastructure initiatives mostly around the urban centers, the impacts of urbanization and sprawl would be on the environment and the natural resources. The research introduces an application of 3D GIS on Manama City.
