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‚Äôs 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.

summary	This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural system’s reproductive process at a microscopic scale with the scope of generating optimal Delaunay triangulated space frames for dynamic loads. The algorithm repositions a firm number of nodes within a space envelope, by establishing Delaunay tetrahedra and, consequently, creating adaptable optimised space frame topologies. The arbitrarily generated tetrahedralised structure is compared against a canonical designed one and the results of this comparison indicate that the method proposed has advantageous properties and is capable of generating an optimum structure that exceeds statically the performance of an engineered tetrahedralised space frame.

title	Reusable Augmented Concrete Casting System - Accessible method for formwork manufacturing through holographic guidance

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

title	The Study of Building Management by using 3D Digital Modeling and Database: ABFM
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 235-243
doi	https://doi.org/10.52842/conf.caadria.2009.235
summary	The principal objective of building management is to control facilities planning and facilities operations and maintenance, that effective criteria in strategic planning about preventive maintenance and predictive maintenance. The key of success in managing the building and facilities is all about collecting and interpreting data on diverse facets of property use. Computer databases are the ideal vehicles in which to log, store and manipulate data; almost unlimited information can be measured and entered en masse. The strength of such information storage is its capacity for expansion and the diversity of subject; it becomes large and requires greater and greater operator familiarity with its structure in order to interrogate successfully. The ultimate solution is to computer–base the entire operation, by using the three-dimensional building modelling to control the operation. This solution will simulate building in virtual environment and the building system data (Architectural part and Engineering part) will collect in digital data type. The digital data will classification and made three-dimensional database relations. This research focus in three sections of the operation as three-dimensional database relationship, topological simulation and smart system, that applied to generate the prototype building management application “Architecture Building Facilities Management: ABFM”.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

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
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	From texture to volume: an investigation in quasi-crystalline systems
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in “De re aedificatoria” (Book VI, Chapter 2), is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty. Only the ornamentation adds pulcritudo to the raw structure and massing. Rather than starting with a volume and applying texture afterwards, the Digital Girih project started with textural operations that informed the overall volume later. The stereometric, top-down methodology is questioned through the bottom-up methodology of the Girih project. Girih lines of traditional Islamic patterns were used as a starting point. The aspect of 3-dimensionality was developed analogue as well as digital, using the deformability of different materials at various scales and digital construction techniques as parameters. The flexibility within the Girih rules allowed the system to adapt to different tasks and situations and to react to different conditions between 2- and 3- dimensionality. The project in that way explored a bottom-up process of form generation. This paper will describe the process of the project and explain the necessity of digital tools, such as Grasshopper and Rhino, and fabrication tools, such as laser cutter and CNC fabrication technology, that were essential for this process.

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 ‚Äúgingerbread houses‚Äù, 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	Content Management Systems Versus Learning Environments
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 285-294
doi	https://doi.org/10.52842/conf.caadria.2009.285
summary	Schools and teachers increasingly apply Online Learning Environments for teaching and course management. In many cases, an existing platform is used to support the curriculum. At the K.U. Leuven in Belgium a campus-wide platform is provided, using a commercial Content Management System. At the same time, the Design and Building Methodology research group at the Department of Architecture, Urbanism and Planning developed a custom portal to organize Computer Aided Architectural Design courses and seminars. Integration of this portal into the university system was rather disappointing, since much of the flexibility and customizability was lost, without any chance of filling in the gaps. This article discusses the possibilities and limitations of existing web-based systems to support Computer Aided Architectural Design teaching and reports on our own experiences from the last decade. A comparison of selected systems is juxtaposed with the requirements derived from these experiences.

doi	https://doi.org/10.52842/conf.caadria.2009.065
summary	This paper reports an investigation of the establishment and performance of a distributed computer rendering system for advanced computer graphics production within a centralized university information technology environment. It explores the proposal that the use of distributed computer rendering systems in industry and universities offers synergies for university-industry collaborative agreements. Claims that cluster computing and rendering systems are of benefit for computer graphics productions are to be tested within a standard higher education environment. A small scale distributed computer rendering system was set up to investigate the development of the optimum use of intranet and internet systems for computer generated feature film production and architectural visualisation. The work entailed using monitoring, comparative performance analysis and interviews with relevant stakeholders. The research provides important information for practitioners and the general public and heralds the initiation of a Centre for Visualization and Animation research within the School of Architecture, Landscape Architecture and Urban Design, University of Adelaide.

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.

doi	https://doi.org/10.52842/conf.caadria.2009.381
summary	This research examines the value of “redesigning the brick,” in creating a new vocabulary of basic architectural building blocks with autonomous reconfigurable robotics. The paper highlights several built examples by the author of robotic architectural environments and the work of architecture students whereby individual modules were created within the context of a design studio and applied to scenarios of space making at various scales. Several strategies for decentralized control were explored dictating how individual parts of a system should behave and how local interactions between individual modules can lead to the emergence of global behaviour. The students schematically designed selfreplicating models which would allow for each object to be able to attach, detach, and reconfigure according to predetermined computational logic. The projects successfully demonstrate various strategies for mechanical design, locomotion and control.

summary	The purpose of this research is to develop a process capable of optimizing the capture of light in a circumscribed space, using a responsive system of skylights. Research is focused on the design of irregular dome-like pavilion spaces circumscribed by curved surfaces, but the envisioned process might be applied to other functional, formal, and spatial typologies. The design of the pavilion starts with the generation of a surface, later tessellated into a matrix of skylights depending on the geographic location and sun orientation. In the constructed pavilion, the skylights react to the variation of daylight intensity during the day to satisfy specified internal lighting needs. Simultaneously, the integration of conception and fabrication using digital tools (CAD-CAM) facilitates the construction of a non-standard, parametric geometry, thereby diminishing the costs of production and allowing for personalization, while assuring global sustainability.

summary	The overall economical benefits of Building Information Modeling are generally comprehensible, but are there other problems with the implementation of BIM as a formulized system in a field that ultimately is dependent on a creative input? Is optimization and economic benefit really contributing with an architectural quality? In Denmark the implementation of the digital working methods related to BIM has been introduced by government law in 2007. Will the important role of the architect as designer change in accordance with these new methods, and does the idea of one big integrated model represent a paradox in relation to designing? The BIM mindset requires changes on many levels.

title	Systems-Thinking: Formalization of parametric process
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. 215-223
summary	This paper details a design process focused on explicit digital parametric modeling as an integral system-outcome design. This investigation isolates and alters a simple geometric form (cylinder) in a constructed architectural design method. Systems are defined as logical, sequential operations inherent to the resultant effects. These operations within each system are composed of various parameters, singular entities containing or referencing data. Given specific data, operations are preformed culminating with corresponding outcomes. The two main components of this research pertain to object extraction and transformation. A single grain silo (cylinder), as the architectural/geometric object under examination, is tested using a system of varied parameters inputted into the program Grasshopper, an “explicit history” graphic plug-in for Rhinoceros. This application is utilized to digitally manipulate parameters as objects in a nodal arrangement. Throughout the operations execution, this isolated silo will be transformed into a multitude of versions, then regrouped into the original cluster of silos to expose the implications from patterning, adjacency, and repetition given the proximity of the each silo and its new parametric characteristics. As the various parameters in specific operations affect the system as a whole, so is each adjacent silo in proximity given the same or similar operation? This then is translated and reflected in the outcome. This research seeks to explore design process by applying constant digital 3-D reductive geometric, modular forms inviting systems thinking in parametric environments that can lead to architectural design implications. By focusing on the technical aspect of the parameterization and valuing functionality rather then style, the process becomes focused on formal qualities as the system-outcome relationships. This research tests the “aesthetic implications” of a varied mode of digital design, namely the investigation of an architectural process utilizing parametric design.

title	A Prototype System for developing two- and Three-Dimensional Shape Grammars

summary	A number of researchers have developed shape grammar systems, with a variety of aims. These systems all help users (to varying degrees) to run grammars, but not to develop grammars. However, we believe that developing grammars is also work and needs to be supported. A system to do this would make it easier and more convenient for people using grammars to do design work. Following the generate-test model, we design and implement a prototype system that supports the user in editing grammars, testing grammars, and switching easily between the two types of activity. We emphasize the graphic nature of the task: the user is all the time working with graphic objects, namely shapes.

title	Análise da Emissão de CO2 em Edificações através do Uso de uma Ferramenta CAD-BIM [Analysis of CO2 emission in construction using a CAD-BIM system]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The main objective of this research is to determine through the use of a CAD-BIM system, the emission of CO2 in the pre-operational phase of construction. Based on a case study in quantitative analysis of materials and the BIM system, it was possible to quantify the amount of CO2 emitted during the pre-operational life cycle of a building. By using this feature you can provide, before the begining of construction, the total CO2 that will released to the environment, and other analysis.
