title The Consideration of Lifelong Owner’s and Property’s Characteristics in Nd Cad System: The case of affordable housing in kingdom of Saudi Arabia
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. 191-204
summary Residential property value is affected by several factors during its useful time. . These factors include people’s lifestyles, traditions and culture, and the way they live and interact with the built environment. The property characteristics such as its location, building quality, adaptability, and energy efficiency would also have an impact on the property value. On the other hand, the nD CAD research that emerged in the late 1990s proposed endless dimensions of CAD modelling that would incorporate the building regulations’ requirements, basic user needs and client requirements. However, there is a need to implement lifelong parameters that would have significant effect on the property value in 3D models during the early stages of design. This can be done through a knowledge base integrated into a 3D model and links the lifelong property’s and the user’s characteristics with the property’s value. A survey was carried out on banks and Real Estate Development Fund (REDF) in the Kingdom of Saudi Arabia to find out the level of impact of lifelong users and property characteristics on the property’s value. The results of the survey showed a number of lifelong property and user driven parameters that may have major impact on the property’s value. The implementation of lifelong parameters in nD CAD models would have a number of benefits. It would provide the decision makers such as banks and investors with a tool to assess the level of impact of possible lifelong factors on the property value and consider alternative schemes. Designers would use it during the early stages of design to produce optimum design solutions that provide an adequate product that is evaluated regarding its lifelong value to the end users. Eventually it would provide a comfortable environment that is tailored to the user’s needs and aspirations, while reserving the property’s lifelong value.

title Unified Energy-Based Qualitative Representation for Building Analysis
source in J McDonnell and P Lloyd (eds), About: Designing. Analysing Design Meetings, CRC Press, pp. 213-229.
summary Currently, when designers develop a building design project, different representations are used for different building subsystems, such as spatial system, electrical system, lighting system, hydraulic system and HVAC. These representations are mainly used in the final design documentation stage. This book presents a qualitative approach to the development of a unified energy-based representation for building analysis called qualitative Archi Bond Graphs (QABGs). QABGs integrate different representations in the architectural domain into a unified representation. They can be applied in the conceptual, intermediate, and final building design stages. Combining graphical representations and qualitative equations, QABGs are applicable for building simulation and analysis for building dynamics in the space-people system and the building energy systems, and for energy interactions between the space-people system and the building energy systems.

title Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
doi https://doi.org/10.52842/conf.acadia.2013.109
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 Testing the relevance of parameterization to architectural epistemology
source Architectural Science Review, Volume 52.2: 135-141
summary Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

title A Design Interaction Tool That Adapts
source VDM Verlag
summary Despite different computerised approaches have been hardwired to solve various complex practical problems; few are founded on an adaptive paradigm such that a computational model interacts with its environment, loosely wires itself and learns from experience like humans do. This book presents our attempt to craft a computational model that learns from interactions and adapts based on its experience. We draw ideas from cognitive psychology in relation to human experiential learning, particularly the notions of ?situatedness?, ?constructive memory? and ?concept formation?. When applied to design activities, which are intrinsically dynamic and interactive, this model constructs concepts from interactions between the agent, the design problem and the use of the design tool. Such a design interaction tool generates knowledge based on the agent?s grounded generalisation from contextual information in a situated manner. Adaptive behaviours emerge from coupled interactions of the system from a macroscopic and a microscopic level. This book is suitable for researchers and students interested in pursuing computerised approaches based on cognitive science and natural computing.

title Architect Friendly: A Comparison of Ten Different Building Performance Simulation Tools
source IBPSA
summary Performance Simulation tools BPS is available internationally. The users of those tools are mainly researchers, physicists and experts who value empirical validation, analytical verification and calibration of uncertainty as defined by e.g. BESTEST. However, literature and comparative surveys indicate that most architects who use BPS tools in design practice are much more concerned with the (1) Usability and Information Management (UIM) of interface and (2) the Integration of Intelligent design Knowledge-Base (IIKB). Those two issues are the main factors for identifying a building simulation program as “Architect Friendly”. Now, with the advancement of BPS tools and the recent announcements of direct links between BIM or non-BIM modeling tools and BPS tools it is important to compare the existing programs. Based on an online survey, this paper presents the results of comparing ten major BPS tools. The following programs are compared: ECOTECT, HEED, Energy 10, Design Builder, eQUEST, DOE-2, Green Building Studio, IES VE, Energy Plus and Energy Plus-SketchUp Plugin (OpenStudio). With 249 valid responses, the survey ranked the tools in three classes and revealed that architects seek the IIKB above the UIM of the interface. Finally, the paper summarizes the key findings and underlines the major requirements for future improvement and development of BPS tools, mainly from an architectural perspective.

summary A system for using organic polymers as electrochromic components for a building’s facade is proposed, and early prototypes are presented. The potentialities of such system, Croma, are considered in two aspects: a) as interactive facades that change opacity in reaction to touch –hence “drawing with transparency”- and b) as elements to automate energy-smart behaviors of a building. Some implications are discussed.

summary Within computational environmental design (CED), different Machine Learning (ML) models are gaining ground. They aim for time efficiency by automating simulation and speeding up environmental performance feedback. This study suggests an approach that enhances not the optimization but the generative aspect of environmentally driven ML processes in architectural design. We follow Stan Allen's (2009) idea of 'field conditions' as a bottom-up phenomenon according to which form and space emerge from local invisible and dynamic connections. By employing parametric modeling, environmental analysis data, and conditional Generative Adversarial Networks [cGAN] we introduce a generative approach in design that reverses the typical design process of going from formal interpretation to analysis and encourages the emergence of spatial configurations with embedded environmental intelligence. We call it Intensive-driven Environmental Design Computation [IEDC], and we employ it in a case study on a residential building typology encountered in the Mediterranean. The paper describes the process, emphasizing dataset preparation as the stage where the logic of field conditions is established. The proposed research differentiates from cGAN models that offer automatic environmental performance predictions to one that spatial predictions stem from dynamic fields.

summary The deconstruction (DeCon) and repurposing (ReCon) of existing structures and materials are worthwhile and relevant endeavors given the potential for such procedures to be more economically and environmentally sustainable than conventional construction methods. Conventional construction methods often utilize virgin materials for the production of architecture, requiring extensive energy to harvest, process, and manufacture the materials for use. Today, we must face the fact that we exist in a carbon-sensitive economy, and demand design approaches that reduce architecture’s impact on the environment. Our goal was to develop a CADCAM ReCon design methodology that would have the potential to mitigate carbon consumption. To explore this goal, students engaged a design research project that looked for novel and innovative approaches to the DeCon and ReCon of an existing barn. The student researchers created parametric models and surface designs derived from the existing materials. The digitally fabricated tectonic design constructions resulted in economical, novel, and material-efficient design methodologies for DeCon and ReCon.

summary The purpose of this project is to provide an interactive platform for clients and design teams to evaluate the consequences of shape, form, and briefing decisions on the energy use, embodied energy, and capital / life-cycle cost of a tall building early in the design process. The Tall Building Simulation (TBS) model is the result of a collaborative partnership between Aedas, Arup, Hilson Moran (HM), and Davis Langdon (DL). It is estimated that most decisions determining the sustainability of a project are made in the first 1 percent of a project’s program, whereas the majority of the information required for sustainability assessment is not usually available or examined until after the concept stage. By this time, most solutions would need design or briefing changes that are too costly to implement. Using the TBS model, architects, engineers, and clients can simultaneously explore the impact of typical technical and design decisions on a tall building’s energy footprint and its dynamic relationship to cost at the briefing stage.

summary This paper presents a parametric analysis where WWR and color glass was varied to determine their influence in the thermal performance of an office building’s room. Design Builder tool was used to calculate the thermal load and the internal gains. The WWR variation in different orientations resulted in a significant increase of the thermal load. The reflective glass allowed a better thermal performance of the room. With the use of computer simulation was possible to analyse many constructive and design characteristics of the facade and its influence on the results, when considered together.

title I think Therefore i-Phone: The influence of Pervasive Media on Collaboration and Multi-Disciplinary Group Work
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 69-84.
summary The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.

title Beyond Traditional CAAD: E-Learning supporting design thinking
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. 71-87
summary A study based on a post-occupancy-evaluation (POE), conducted in housing developments in the region of Campinas, Brazil, evaluated quality of life and sustainability indicators. These indicators were then related to site planning design guideline for low-income public housing projects that considered recommendations for integrated community and security, street and path system and parking, public and private open space and landscaping. Since this work is part of a broader study, which aims to develop evaluation tools, the proposed design guidelines were used by students in a graduate class, in order to verify its effectiveness. Bloom’s Taxonomy was used to determine educational goals for design thinking in this class. First design thinking was instigated based on students’ prior knowledge of life quality and sustainability indicators for housing design. Comprehension of proposed design guidelines was stimulated by the reading and discussion of related literature, paraphrasing or extension of proposed design guidelines and respective illustration with reference images. An existing low-income housing development, with award winning design, was selected and an evaluation of its conformance to proposed design guidelines was conducted comparing site or design images to reference images. This evaluation subsidized a design exercise for the selected housing development. The class was offered as a partially distance course with an agenda including: tutorials, theoretical classes, seminars and conceptual discussions. A new Brazilian open source e-learning environment was experimented and critiqued. Beyond traditional CAAD tools others such as wiki, blog, polls, chat, conferencing, web authoring and visit broadcasting supported collaborative learning and design. Results indicate the viability of design teaching in distance education courses for competent designers; however the experience shows the need for innovation in synchronous communication and visualization tools specific for architectural design users. Students evaluation of selected housing development and final projects indicate that the proposed guidelines for low-income public housing projects successfully supports the decision making process in order to incorporate quality of life and sustainability indicators in design. The experience presents a model of design education which incorporates technology integrated to human and environmental dimensions.

summary This paper reports on three approaches to the translation of Gaussian surface models into scaled physical prototype models. Using the geometry of Eladio Dieste’s Gaussian Vaults, the paper reports on the aspects encountered in the process of digital to physical prototype fabrication. The primary focus of the paper is on exploring the design geometry, investigating methods for preparing the geometry for fabrication and constructing physical prototypes. Three different approaches in the translation from digital to physical models are investigated: rapid prototyping, two dimensional surface models in paper and structural component models using Computer Numerical Controlled (CNC) fabrication. The three approaches identify a body of knowledge in the design and prototyping of Gaussian vaults. Finally the paper discusses the digital to fabrication translation processes with regards to the characteristics, benefits and limitations of the three approaches of prototyping the ruled surface geometry of Gaussian Vaults.

title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.

summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title A Multi-dimensional Exploration of Urban Attributes by Data Mining
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title A Syncretization Of Architecture, Engineering And Science:The use of CAD technology as a pedagogical tool in the teaching of environmentally sustainable design
source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary Energy consumption in buildings is responsible for about 40% of Australia’s greenhouse gas emissions. It is quite feasible that the energy consumption in buildings can be halved, but energy performance analysis must be integral to the entire design process. This imperative has led the authors to propose that architecture, engineering and science should be syncretized in the design process. This syncretization shares some features of the rhizomatic approach introduced by Deleuze and Guattari (2007). In rhizomatic systems all points can be, and should be connected. A rhizome can be considered as a space that develops, not from a point but from milieux. In the expansion of a rhizome, elements of the system do not follow tracings of other elements but they form a map of new vistas. Likewise, a syncretic approach is oblivious to the traditional boundaries between architecture, engineering and science. Syncretization has the potential to enrich the intellectual lives of architects, scientists and engineers, and it would have profoundly beneficial performative benefits.
