title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
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 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 Parametric Modelling of Architectural Surfaces
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 635-644

summary Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

title Modelling Behaviour of Configurable VR Applications
source International Journal of Architectural Computing vol. 7 - no. 1, 77-103
summary Creation of complex behaviour-rich and meaningful content is one of the main difficulties that currently limit wide use of virtual reality technologies in everyday applications. To enable widespread use of VR applications new methods of content creation must be developed. In this paper, we propose a novel approach to designing behaviour-rich virtual reality applications, called Flex-VR. The approach enables building configurable VR applications, in which content can be easily created and modified by domain experts or even common users without knowledge about VR design and computer programming. The VR content is configured from reusable programmable content elements, called VR-Beans. Appearance and behaviour of the VR-Beans are controlled by scripts programmed in a novel high-level language, called VR-BML (Behaviour Modelling Language). The language enables specification of generic behaviours of objects that can be dynamically composed into virtual scenes. The paper introduces the Flex-VR component and content models, describes the VR-BML language and provides an example of a Flex-VR application in the cultural heritage domain.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Performative Building Skin Systems: A Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
source International Journal of Architectural Computing vol. 7 - no. 4, 643-676
summary Morphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioral and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems.

doi https://doi.org/10.52842/conf.caadria.2009.043
summary For sustainable building design, computational tools, mostly in the form of simulations, are employed to determine loads and to predict systems performance typically in terms of energy use. Currently, sustainability, in the building domain, is judged by a rating system. Design choices are validated, by measuring against one. The objective of the framework is to provide a general approach to processing the informational needs of any rating system, by identifying, categorizing and organizing relevant data requirements. Aspects of sustainability that designers deal with intuitively will have a structured guideline and gauge as one selects a rating system of choice.

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.

title Thermal Simulation In Residential Building Within Computer Aided Architectural Design: Integrated model
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. 235-243
summary Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

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 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 Daylighting is an important part of designing sustainably. Daylighting is the use of natural light for primary interior illumination. This reduces our need for artificial light within the space, thus reducing internal heat gain and energy use. Direct sunlight, once it enters the building, is not only light but heat, and that additional heat will need to be taken into account in your energy analysis." While Autodesk Revit Architecture 2010 (ARA) itself cannot perform the actual analysis, there are some ways to do that. This papper focuses on the study of parametric modeling using a BIM tool for daylighting analysis. This paper presents the first part of the building method of LUME, a plug-in maked whit C# programming language in Microsoft Visual Studio 2010 and ARA Software Developer Kit (SDK) package. The script accepts as its input a standard three dimensional model of building opening and his position on space.

doi https://doi.org/10.52842/conf.acadia.2013.109
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 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.

summary This study aims to present a classification of methodological procedures for using computer programmes to simulate architectural historical heritage. Produced for a Master’s Degree dissertation in Architecture, the methodology was developed based on several analyses of applications, possibilities and restrictions, with the assistance of photogrammetric reconstruction and several computer-graphics programmes. The files generated enable production of animations recording the changes experienced by buildings at various historical periods. These procedures were applied to the simulation of several buildings around the Praça Dante Alighieri in the centre of Caxias do Sul, Rio Grande do Sul, demonstrating their appropriateness and effectiveness and also showing the potential of computer-simulation resources for the historical environment, both educationally and in appreciation of architectural heritage.

title Automatic Extraction of Planar Clusters and their Contours on Building Facades Recorded by Terrestrial Laser Scanner
source International Journal of Architectural Computing vol. 7 - no. 1, 1-20
summary Since 3D city models need to be realistic not only from a bird's point of view, but also from a pedestrian's point of view, the interest in the generation of 3D façade models is increasing. This paper presents two successive algorithms for automatically segmenting building façades scanned by Terrestrial Laser Scanner (TLS) into planar clusters and extracting their contours. Since majority of façade components are planes, the topic of automatic extraction of planar features has been studied. The RANSAC algorithm has been chosen among numerous methods. It is a robust estimator frequently used to compute model parameters from a dataset containing outliers, as it occurs in TLS data. Nevertheless, the RANSAC algorithm has been improved in order to extract the most significant planar clusters describing the main features composing the building façades. Subsequently, a second algorithm has been developed for extracting the contours of these features. The innovative idea presented in this paper is the efficient way to detect the points composing the contours. In order to evaluate the performances of both algorithms, they have successively been applied on samples with different characteristics, i.e. densities, types of façades and size of architectural details. Finally, a quality evaluation based on the comparison of planar clusters and contours obtained manually has been carried out. The results prove that the proposed algorithms deliver qualitative as well as quantitative satisfactory results and confirm that both algorithms are reliable for the forthcoming 3D modelling of building façades.

title Contextual ontology support as external knowledge representation for building information modelling
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 487- 500
summary There is an increasing awareness of formal ontologies in knowledge-intense problem domains in the AEC industry. This paper analyzes the general use of ontologies, points to the importance of context-dependent ontology descriptions in AEC, and describes the use and management of multiple (external) ontologies as knowledge management tools within a complex information model of a building performance assessment tool CLIP (Computational support for Lifecycle Integral Performance assessment), previously developed by the authors. The paper provides a discussion of our approach, analysis of the benefits and limitations of external ontologies, suggestions for further development and research areas for the integration of multiple AEC knowledge representations.

summary The architectural planning process is influenced by social, cultural and technical aspects (Alexander, 1977). When focussing on computer based planning for retrofitting or modification of buildings it becomes clear that many different data formats are used depending on a great variety of planning methods. Moreover, if building information models are utilized they still lack some essential criteria. It is rarely possible to attach individual data from survey systems. This paper will show both a way to add data from building survey systems as an example for special data attachment on IFC files and how to utilize content management systems for IFC files, deviated plans, lists of building components, and other data necessary in a planning process.
