source Behaviour and Information Technology 1986 v.5 n.3 p.259-271
summary In an effort to understand how computer-assisted design (CAD) can be optimized in an organizational setting, perceptions and attitudes of CAD users about their jobs and workplace are compared with those of non-users. Results indicate that the implementation of CAD may not result in the expected benefits if CAD is not appropriately managed. Job unpredictability, job autonomy, and job interdependence are three areas in particular needing management attention if CAD benefits are to be achieved.

summary The waste produced in construction and demolition presents social, economic, and environmental challenges on a global scale. Research suggests that effective decision-making mechanisms are needed during preliminary design stages to minimise the production of waste. In early research, we presented a beta version of a waste reduction tool which is now in need of a User Experience (UX) and Interaction Experience (IX) strategy to meet our research aims of (a) supporting architects in making informed decisions and (b) offer general as well a specific design optimisation to reduce waste. Thus in our research, we arrived at a point that required an investigation into computational methods and strategies to meet these aims. While optimisation and decision-making in architecture are often achieved through generative design strategies, we aim to investigate and discuss alternatives. Thus we propose the hypothesis of employing augmented intelligence. The paper presents work in augmented intelligence undertaken outside the architecture discipline and presents our literature review with a discussion and conclusion.

title A model of information management for construction using information technology
source Automation in Construction 10 (2) (2001) pp. 257-263
summary The construction industry is slow in utilising information technology (IT) to manage projects. Application of IT is piecemeal, discrete and non-systematic. Managing information for construction projects is crucial in order to make good and full use of IT in the construction industry. This paper proposes a simplified model to achieve managing information for construction by utilising the ubiquitous Internet technologies. The openness of these technologies is receiving attention of not only academics and amateurs but also of business entities and government organisations. A database-web link is required in order to properly store, organise and archive information. Internet technologies can be adapted to a corporate Intranet or business Extranet. Experiencing the advantages of Internet technologies is crucial in order to avoid negative perceptions.

summary This paper presents a specific aspect of a post-graduate research entitled "Between Design and Designer: Considerations on digital design" and investigates the designer in the digital design processes. It is believed that the unique and subjective nature of the designers are key part of the result and the own choice of architectural design method. Currently, digital technology has enabled new design methods, casting a revaluation of theories related to design. Considering the complexity of contemporary designs it is necessary to open the black box of design and show the context in which the design acts or should act.

title Control of Morphological Variation Through Population Based Fitness Criteria

summary A primary challenge for the application of an evolutionary process as a design tool is the ability to maintain variation amongst design solutions while simultaneously increasing in fitness. The 'golden rule' of balancing exploration versus exploitation of solutions within the population becomes more critical when the solution set is required to present a controlled degree of phenotypic variation but ensure that convergence of the solution set continues towards increased levels of fitness. The experiments presented within this paper address the control of variation throughout the simulation by means of incorporating a population-based fitness criterion that is utilised as a fitness objective and is calculated dynamically throughout the algorithmic run in both single and multi objective design problems.

summary The use of evolutionary solvers in design has introduced the potential of dealing with multiple conflicting objectives under a single design model. The experiments presented in this paper employ an evolutionary solver towards the generation of a 4x4 urban superblock in the city of Barcelona, one of the highest population density cities in Europe. The superblock is based on Cerda's iconic 8-sided block and takes three conflicting objectives into account, aiming not only to achieve a high density proposal but one that considers block relations, as well as green space throughout the city. The design is based on principles of evolutionary science, generating a population of solutions, whose individuals are ranked and selected based on a fitness criteria. Rather than aiming to reach a single 'optimal' solution, the model produces a population of solutions that are optimized in relation to the design environment.

title Evolutionary algorithms for generating urban morphology: Variations and multiple objectives
source International Journal of Architectural Computing vol. 17 - no. 1, 5-35
summary Morphological variation of urban tissues, which evolve through the optimisation of multiple conflicting objectives, benefit significantly from the application of robust metaheuristic search processes that utilise search and optimisation mechanisms for design problems that have no clear single optimal solution, as well as a solution search space that is too large for a ‘brute-force’ manual approach. As such, and within the context of the experiments presented within this article, the rapidly changing environmental, climatic and demographic global conditions necessitates the utilisation of stochastic search processes for generating design solutions that optimise for multiple conflicting objectives by means of controlled and directed morphological variation within the urban fabric.

summary The paper describes the development, testing, and initial findings of a design tool that generates parametrically defined, semi-automatically analyzed, and visualized structural performance of specific truss designs. The prototypical design tool provides structural truss solutions for spans of uniform to non-uniform surface curvatures. Real-time visual structural performance feedback enables the designer to more rapidly develop viable and potentially more efficient designs under user defined load conditions. The research methodology is an example of reinforcing structural learning and intuition within the design process. The research presents findings of the impact of iterative and interactive structural feedback through the development of a parametrically integrated structural truss analysis tool for aiding in design decision support.

title Among The Fear of the Virtual and Radical Typologics
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 713-724
summary It might seem that architecture has been forced to choose, once again, between two worlds of existence. One of them might be the construction of the tangible, the other, a “formal fantasy” that will never reach a legitimate status among the “tectonic” or the “structural”. This vague spectrum has confirmed the fear of loosing typology as a proof, of loosing a foremost validation for architecture. But one could see the virtual as a possibility to generate a structure of discourses and interactive tactics to reformulate the typological. This meaning that the virtual could transcend the so called “graphic” stigma and actually produce the discourses and spatial strategies to radicalize typologics.

title Travels in Space and Time, Explorations of Virtual SoundScapes, Multi-dimensionalism of Digital Music
source International Conference on Generative Art
summary Composition and performance of Computer Music still keep some of the features of traditional music, together with new ones. Rhythm, melody, harmony can still be present in new paradigms (even if they are not necessarily required when dealing with computer music), but new compositional parameters are coming to light, causing the term «music» not always to be appropriate to describe new phenomena of sonic art. This paper will show some new paradigms of this kind of sonic art, as well as different view of old ones. Any past dogmas should be wiped out when dealing with digital arts. The rebellion against tonality of the first half of 20th century is surpassed now, and I believe that new music could use harmonic intervals without generating conflicts with the ideological problems which arose at that time (even if there are still many people who don’t admit it). Actually, digital domain opens a huge amount of unexplored worlds, making any past ideological dogma a prison we should free ourselves from. Nowadays, making music has many things in common with visual arts and scientific research. Many musical parameters can be applied to video arts, architecture, and vice-versa. Structure of sound has a lot of similarities with many other physical phenomena such as inner atomic structure, particle physics, astronomy, biology etc. This paper will deal with new uses and interpretations of old musical parameters (rhythm, harmony, melody) together with a presentation of some of the new ones. Debated topics are: ? Harmonic/inharmonic sounds, rhythm and melodies. The Deep Harmony (the harmony of spheres or cosmic harmony CYCLES). ? The inner structure and evolution of a single sound ? Interpretative music: Music generated by exploration of soundscapes or sonic architectures, generative processes constrained by interpreter’s gestures, state transitions between musical structures. ? Generative music: stocastic generation, algorithmic composition, levels of action. ? Music or non-music this is the problem (a terminology problem) ? Hyper-spatial music, virtual times, hyper-times. Time travels by means of sonic matter. ? Visual music. Generating 3D video by means of musical processes.

source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 117-125
summary Programming takes designers away from typical domain- and task-based interfaces such as three-dimensional modellers. It thus imposes additional cognitive load on the already challenging design task. Programming in the model is a system design strategy that embeds the act of programming in a 3D CAD model. This paper presents the argument for programming in the model and two user interface constructs that support such programming.

title Reinterpreting Rasmi Domes with Geometric Constraints:A Case of Goal-seeking in Parametric Systems
source International Journal of Architectural Computing vol. 6 - no. 4, 375-395
summary Geometry has long been a generator of architecture. In traditional Persian architecture, Rasmi domes project a drawing onto a predefined 3D geometry. In fact, the word 'rasmi' and the verb for drawing in Persian have the same linguistic root. Projection is readily done in manual drawings or conventional CAD programs. From a constraint perspective, the dome is constrained by the drawing and the 3D geometry. If the latter constraint is replaced by invariance of distance on the original drawing, a class of domes results, but members of this class cannot be computed conventionally. Class members are developable from a planar layout of triangles, which is, in turn, generated by a simple drawing rule. This yields a parametric structure of four parameters. Three determine the initial planar diagram. One determines configuration. Further, domes in the class are mechanisms: they are not fully specified by the constraints and parameters. We develop the geometric constraints representing the location of the defining points of a dome and present a goal-seeking algorithm to solve the constraints within a propagation-based parametric modeling system.

summary Programming, often called scripting, has become a key feature in most CAD systems and an equally key area of expertise in CAD. However, programming surrenders many of the benefits of direct manipulation and introduces notational elements that are cognitively distant from the designs being created. In addition, it creates barriers to use and is often perceived as being too difficult to apply. We introduce Programming In the Model (PIM) through a prototype, implementing live side-by-side views, multi-view brushing and highlighting, live scripting, auto- translating from modeling operations to script and localized relational information within model windows. A qualitative user study confirms PIM’s features and raises issues for future development. A key result is the need for multi-directional extreme liveness , that is, maintaining consistency of action across views at the smallest possible scale. We argue that PIM principles are applicable in textual and visual programming alike.

A shared knowledge base is at the core of the proposed system. The system is designed to allow independent modules that target the different aspects of a building design and analysis (e.g. thermal analysis and morphological analysis) to access and modify the knowledge contained in this knowledge base. The paper discusses the structure of the system and issues pertaining to its implementation. An example of the use of the system is illustrated. Conclusions and findings about the utility of the system are drawn.

title Representing Collaborative Multi- Knowledge Agents as Generic Rules
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary This paper discusses the internal representation of a multi-knowledge agent decision support system that was developed for building thermal design. The system is able to provide designers with specific problem detection in thermal design without the use of rules of thumb. The paper describes how generic rules can be used as virtual agents and how these agents can interact using a blackboard model. The generic rules utilized use logical variables as a strategy to capture generality. This allows the rules todeal with variables that can be replaced by any possible term. In addition, it allows the rules to be equivalent to the infinite set of rules that could be obtained if the variables were replaced in all possible ways by terms. In the system, these terms include the building elements and systems that affect the thermal behavior of the building. Problems associated with agent conflicts and how they were resolved in such a model are described.

source Proceedings of the Solar ‘96 Conference. Asheville, North Carolina: American Solar Energy Society, 1996, pp. 271-276
summary This paper describes an experiment that integrates shadow casting methodology and thermal simulation algorithms developed by the authors. The 3D shadow procedures use a polyhedral representation of solids within a Cartesian space that allows for accurate casting of shadows. The algorithm is also capable of calculating surface areas of polygonal shadows of any arbitrary shape and size. The thermal simulation algorithms – using the Transfer Function Method (TFM) – incorporate the shaded area calculations to better predict solar heat gain from glazing based on transmitted, absorbed, and conducted cooling loads. The paper describes the use of a 3D computer model to illustrate the impact of the pattern and area of shading on the visual and thermal properties of building apertures. The paper discusses the objectives of this experiment, the algorithms used, and their integration. Conclusions and findings are drawn.

title Interfacing with the real space and its performance
source International Journal of Architectural Computing vol. 3 - no. 1, 43-56
summary This paper presents an immersive gesture-recognition-based system to visualize the indoor thermal environment using Computational Fluid Dynamics (CFD). To enable efficient visualization of CFD in actual space, an Augmented Reality system was integrated with a CFD simulation engine. To facilitate efficient data manipulation of the simulated postprocessed CFD data and to increase user control of the immersive environment, an intuitive method of Human-Computer Interaction (HCI) has been incorporated using gesture and speech recognition. While gesture recognition aids in transforming hand postures into command functions through forward kinematics and computation of hand segment positions and their joint angles, speech recognition allows better control of the data manipulation. This enabled real-time interactions between the users and simulated CFD results in actual space.

title Identification and Visualisation of Construction Activities’ Workspace Conflicts Utilising 4D CAD/VR Tools
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the same workspace and may cause health and safety hazard issues. The aim of this paper is on presenting a computer-based method and developed tool to assist site managers in the assignment and identification of workspace conflicts. The author focuses on the concept of ‘visualising space competition’ between the construction activities. The concept is based on a unique representation of the dynamic behaviour of activity workspace in 3D space and time. An innovative computer-based tool dubbed PECASO (Patterns Execution and Critical Analysis of Site-space Organisation) has been developed. The emerging technique of 4D (3D + time) visualisation has been chosen to yield an interesting 4D space planning and visualisation tool. A multi-criteria function for measuring the severity of the workspace congestions is designed, embedding the spatial and schedule related criteria. The paper evaluates the PECASO approach in order to minimise the workspace congestions, using a real case study. The paper concludes that the PECASO approach reduces the number of competing workspaces and the conflicting volumes between occupied workspace, which in turn produces better assessment to the execution strategy for a given project schedule. The system proves to be a promising tool for 4D space planning; in that it introduces a new way of communicating the programme of work.

title Applying generative modeling procedure to explore architectural forms
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 697-712
summary Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design process mainly the practicality of design during the conceptual design stage; it is cumbersome to develop construction drawings for complex architectural forms; and the necessity for producing conceptual designs quickly in less time as design requirements and decisions are constantly being changed. This paper initially reports on a practical development of a computer program which generates architectural massing designs based on integrating forms generation technique in a design scheme. The influence for this development was inspired by Spirolaterals technique used in generating complex 3D architectural forms that are based on parametric shape configuration. The development has three goals: to review the principles for constructing generative forms in the conceptual design stage using simple CAD tools, to assist in the production of design schemes based on a few basic shapes and rules, and to explore 3D forms finding and generation without the need to write a complicated computer program that are difficult to produce by hand. The development resulted in generating an interesting number of 3D compositions. The author applied this technique to experiment during the production of a design scheme. The paper hence describes the current development of ArchiGen tool to produces generative 3D forms utilizing ArchiCAD © GDL programming language. The tool is embedded within ArchiCAD for generating 3D shapes. One of the main features of this implementation is that users are able to sketch 2D shapes and the tool will deform its three dimensional generation. Moreover, the user being able to abstract the architectural character from the resulting complex 3D shapes. This development extends current related work by allowing the designer to load shapes into ArchiGen which acts as vocabulary of shapes for a design scheme constraints. It is intended from this work to inspire future work focusing on using generative tools in the early conceptual design stages.

title A Pixels-Based Design Approach for Parametric Thinking in Patterning Dynamic Facades
source Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 654-673
summary In today’s Architectural design process, there has been considerable advancements in design computation tools that empowers designer to explore and configure the building façades schemes. However, one could formally argue that some processes are prescribed, lacks automation and are only for the purpose of visualizing the aesthetic design concepts. As a result, these design concept explorations are driven manually to exhibit variations between schemes. To overcome such limitations, the development presented here describes a proactive approach to incorporate parametric design thinking process and Building Information Modeling (BIM). This paper reports on an ongoing development in computational design and its potential application in exploring an interactive façade pattern. The objective is to present the developed approach for exploring façade patterns that responds parametrically to design-performance attractors. Examples of these attractors are solar exposure, interior privacy importance, and aesthetics. It introduces a paradigm-shift in the development of design tools and theory of parameterization in architecture. This work utilizes programming script to manipulate the logic behind placement of faced panels. The placement and sizes for the building facade 3D parametric panels react to variety of Analytical Image Data (AID) as a source for the design-performance data (e.g.: solar exposure, interior privacy importance, and aesthetics). Accordingly, this research developed the PatternGen(c) add-on in Autodesk ® Revit that utilizes a merge (or an overlay) of AID images as a source to dynamically pattern the building façade and generate the facade panels arrangement rules panels on the building exterior. This work concludes by a project case study assessment, that the methodology of applying AID would be an effective dynamic approach to patterning façades. A case-study design project is presented to show the use of the AID pixel-gradient range from Red, Green and Blue as information source value. In light of the general objectives in this study, this work highlights how future designers may shift to a hybrid design process.
