title	This is not a Glitch: Algorithms and Anomalies in Google Architecture
source	ACADIA 14: Design Agency [Proceedings of the 34th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 9781926724478]Los Angeles 23-25 October, 2014), pp. 389-398
doi	https://doi.org/10.52842/conf.acadia.2014.389
summary	This paper presents a body of research that explores the ways in which computer vision is being paired with big data collection engines to map/simulate the physical environment in digital space. These algorithms are producing increasingly ubiquitous representations of 3 dimensional space which are accessed by governments, security agencies, private citizens and in the context of this paper, designers. Designers often accept these simulations as highly accurate despite understanding very little about how they are produced.

title	Binocular Disparity and Depth Cue of Luminance Contrast
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 637–646

summary	Luminance contrast has been identified as an effective depth cue through perceptual studies using digital images generated by the integrated technologies of physically based lighting simulation and perceptually based tone mapping. However, the prior established framework utilizes a single camera viewpoint, failing to address the binocular vision of the human visual system. In this study, the computational framework is extended to incorporate 3-dimensional (3D) stereo display technology. Psychophysical experiments were conducted to investigate the depth effect of luminance contrast on the experimental scenes presented on conventional and stereo displays. The objective of this study was twofold: first, to investigate the effect of luminance contrast on depth perception, considering binocular vision; second, to further advance the visual realism of the computer-generated environment to reflect the perceptual reality of static pictorial and binocular disparity cues.

title	Computational Analysis of Architectural Visual Space Along Walking Path by Using Virtual Reality Display
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 709–718
doi	https://doi.org/10.52842/conf.caadria.2014.709
summary	This study evaluated architectural space quantitatively based on ambulatory vision. In this paper, we propose a computational analysis method of a visual space along a walking path by using a virtual reality display. A display image of our system is shown from the first-person perspective. We consider the perspective to be the visual field of the users. To convert the perspective into a visual field, we take advantage of depth buffer data, which can specify how far a pixel of an object is on the perspective. To analyse a visual space by a sequence of visual field, we quantify the geometric characteristics based on isovist theory. A virtual reality display, which employs a wide range view angle and a head-tracking system, also enables us to analyse the relation between the visual field and head motion.

title	Creativity and VR Use
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 719–728

summary	Creativity with its various processes is involved in all design actions. Creativity used in architectural design is different than creativity in other domains. However, creativity in general with its related cognition processes has no general theory. This research proposes certain activities of initial architectural design phases in which the role of activity is important. The research proceeds to present a case study of two architectural design studios in which a VR environment is employed in order to investigate the effect of VR use on the creativity in those initial design phases. The research applies a methodology of qualitative and quantitative analysis. Various architectural design factors are neutralized to overcome the influence generated from human factors variation and design thinking prejudice on architectural designing and the associated creativities.

title	Collaborative Environments in Small and Medium-sized Enterprises in Architecture, Engineering and Construction
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 183-193
summary	The general picture of Architecture Engineering and Construction (AEC) is of a sector that is a pyramid with control being in the hands of large players with a large base of Small and Medium Enterprises (SMEs). It ensues naturally that SMEs are key players in supporting the large companies. This suggests that, the AEC sector has a continuous demand for collaboration. Collaborative working has been implemented in numerous companies. These efforts have resulted in the wide recognition of the opportunity that emerging technologies offer the AEC sector. It is, however, commonly observed that SMEs are likely to magnify the sector trend and to be less technically forward thinking than large companies. The main focus of this paper is, therefore, to explore the use of IT within AEC, and the barriers and different implementation factors that can influence SMEs to develop, in response to business pressures using the opportunities provided by collaborative technologies.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

title	Integrated Generative Technique for Interactive Design of Brickworks
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 49-64
summary	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

title	Virtual Reality: an approach for building Makkah’s architectural identity
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 331-342
summary	This paper explores a new approach in the architectural design process aiming to construct Makkah's architectural identity. Makkah, which is a city of unique sacred values, has been losing its battle to preserve it heritage buildings. Traditional districts with their heritage buildings have been cleared in order to construct skyscrapers to accommodate the increasing number of pilgrims. While some argue for preserving heritage buildings others insist in building more skyscrapers. Within these conflicting views, architects and urban designers use CAD software to document heritage buildings without informing the future architectural design process. This paper argues for adopting digital architecture as an approach for preserving the architectural heritage of Makkah by studying heritage buildings as systems that can be digitally represented in virtual world. This goes beyond the physical representation of heritage artefacts to investigate in depth the logic that guide the design process. The roushan, which is one of the unique heritage artefacts in Makkan's architecture can be an interface between reality and the virtual environment in the design process. This goes behind modeling the roushan, to employ the principle of virtual representation in the design process. The digital representation of heritage becomes the realm for research transforming the virtual into reality. The hope is to produce an architecture that is related to its local heritage, contemporary in design and responsive to its environment, as well as to advocate principles, references and techniques at the core of the design process, in an educational and professional context. In broader picture the goal is to achieve a city that is responsive to human activities adapted to changes, sustainable in physical forms and social relations and above all unique in design and identity.

title	Using Genetic Algorithms for the Generation of New Designs Derived from Islamic Schools Plans
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 119; 431-442
summary	Historic buildings are fruitful sources of architectural concepts which can be used to generate new designs characterized by authenticity and originality. Design computing methods have used varied techniques of knowledge representation in deriving new designs from architectural precedents such as: case-based design and genetic algorithms. This research has adopted genetic algorithms, a simulation of biological evolution to generate new plans from old ones belonging to the Islamic historical schools. The implemented method represents architectural knowledge in a simple schema (chromosome) and allows it to be modified easily using crossover operation to generate new plans with high fitness value. The research considered the fitness function as a measure of differences among the design characteristics of the sample of the Islamic schools. The results show the effectiveness of genetic algorithms in both analyzing past precedents and synthesizing their characteristics to produce new designs.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

title	Temporary Architecture: An urban mirage
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 405-413
summary	One of the emerging multidisciplinary contemporary art practices is interactive installation art, which is concerned with constructing a temporary artistic environment that is digital, responsive and engaging. It is usually displayed within existing architectural context whether indoor in a gallery space or outdoor in a public space. Recent examples of such art projects show that interactivity and illusion are effectively present and highly influential in the perception and memory of the place. A digital display on a building façade can remain attached to the history of the site in the spectator’s memory even after the display is removed. An interactive space that involves body response and emotional sensory interaction can determine the narrative perceived from the experience. These trends seemingly bring together the physical context and the digital space to contain the spectator. The two mediums are merged to provide a new genre of space, hence a new mode of perception where the art space mediates people’s movement and overlay the context with new meanings. Multiple backgrounds are involved in the creative process of interactive installation art, all of which involve examining various concepts through artistic engagement with temporary spaces. Here, particularly because of interactivity and immerseveness, the spectator becomes part of the performance (the subject); with his moving and reacting he activates the narrative and probably gives it its shape. This paper aims to explore the potentials of the digital spatial display to enhance or weaken our sense of belonging to the surrounding environments while creating an illusionary space within the real physical one. It also aims to discuss how this influence would affect the memory of the mixed experience; the installation being digital, temporary and illusive and the space being physical, permanent and real. What happens to the “spectator” when contained by the digital-interactive and the physical medium(s)?. In order to unfold the mentioned questions, the study uses theories of perception and performance reflected on live case studies of recent art projects where the researcher becomes a member of the audience and an observer at the same time in order to trace the journey inside this new medium. In an era where time is being more difficult to grasp and identities of visual culture is becoming more difficult to define, temporary responsive environments can provide some openings where space becomes durational, yet, influential, and where people’s movements become more meaningful in the visual terrain.

title	Pedagogic Approach in the Age of Parametric Architecture: Experimental method for teaching architectural design studio to 3rd year level students
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 211-226
summary	In this era, Architectural Design Practice is faced with a paradigm shift in its conventional approaches towards computational methods. In this regard, it is considered a pedagogic challenge to boost up knowledge and skills of architectural students’ towards an advanced approach of architectural design that emphasizes the potentials and complexity of computational environments and parametric tools for design problem solving. For introducing the concept of Parametric Oriented Design Methods to 3rd year level architectural students, an experimental pedagogic course was designed in the scholastic year of 2012-2013 at German Jordanian University GJU (School of Architecture and Built Environment SABE) to approach this concept. In the preparation phase, the experimental course was designed to incorporate structured instructing and training method to be consecutively performed within experimental lab environment to target predetermined learning outcomes and goals. The involved students were intentionally classified into three levels of previous involvement associated with the related software operating skills and computational design exposure. In the implementation phase, the predetermined instructing and training procedures were performed in the controlled environment according to the planned tasks and time intervals. Preceded tactics were prepared to be executed to resolve various anticipated complication. In this phase also, students’ performance and comprehension capacity were observed and recorded. In data analysis phase, the observed results were verified and correlations were recognized. In the final phase, conclusions were established and recommendations for further related pedagogic experiments were introduced.

title	Evolutionary Algorithms in Islamic Architecture

summary	The cosmological nature of Islamic architecture makes it a useful case study for the capability of the adaptation, assimilation and accommodation with the development of evolutionary algorithms and their applications in architectural design. Genetic algorithm derives its structure from the observation of nature. We shall review the concept of intelligent agents and their organization into complex adaptive systems as well as genetic-type algorithms for learning and evolution. Since algorithmic art consists of generation of images on the basis of algorithms, algorithms can be viewed as a notation, and notation is something that music has but visual artefacts in general miss. This paper aims to discover the role of evolutionary algorithms in historical Islamic architecture. Also, we shall try to investigate the way in which the future development could occur not only through the discovery of new facts or theories, but also through the rise and dissemination of new visions having different explanation of Islamic architecture that considers it as a result of serious application of formation through evolutionary genetic algorithms.

summary	Several architectural studies tackled the methodologies of teaching the architectural design subject in general and their relation to the use of computer in particular. The trends varied in accordance with the research that is relevant to the subject due to its importance in generating new architectural models, but it didn’t crystallize a theoretical framework that identifies clear and specific vocabularies related to the methodology of teaching the computer-aided architectural design. The current study discusses the importance of this concept in an attempt to explore the particular problem represented by the non-clarity of this methodology in the department of architecture in Mosul University. Therefore, the problem of the research crystallized and its objective and its methodology were identified and this was represented by constructing a theoretical framework which includes several main items. Then the theoretical framework was applied to selected projects of architectural department students in order to manifest the particularity of teaching the computer-aided architectural design. Results showed the distinction of this department as this methodology led to the derivation of different architectural products in accordance with the particular effects using the computer technologies. The results also manifested the change in the architectural design trend that was caused due to the digital intervention in the way of the student's thinking from one hand and the components and the elements of the building from the other hand that the quality of the design can be improved by using the computer and the quantity will be more in shorter time.

title	Experimenting with CAAD: As a means to solve conceptual design by architecture and architecture technology students
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 227-239
summary	This study sought to characterise students’ design activity while designing with Computer Aided Design (CAAD) professional programs and its impact on the students’ design process. The design protocol participants were final year students (architectural design and architectural technology), who have spent at least four years in a school of architecture and were confident CAAD users. The analysis represents four CAAD-based protocols of final year students at a school of architecture. The analysed protocols varied in more than one aspect. This variation includes: (1) programs, (2) the mode of using programs whether single or multiple, (3) protocol segments (total number, duration and frequencies), and (4) design categories and total time spent in designing. In light of the study results, the participants demonstrated that, for the same design problem, restraining the conceptual design medium would not necessarily bind them to a certain design strategy. However, there are some disciplinary differences between AD and AT final year students, on how CAAD is used during to solve conceptual design.

title	Towards a BIM-Based Energy Rating System

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary	Surrogate models (SM) present an opportunity for rapid assessment of a building's performance, surpassing the pace of simulation-based methods. Setting up a simulation for a single concept involves defining numerous parameters, disrupting the architect's creative flow due to extended simulation run times. Therefore, this research explores integrating building energy analysis with advanced machine learning techniques to predict heating and cooling loads (KWh/m2) for single and multi-zones in buildings. To generate the dataset, the study adopts a parametric generative workflow, building upon Chou and Bui's (2014) methodology. This dataset encompasses multiple building forms, each with unique topological connections and attributes, ensuring a thorough analysis across varied building scenarios. These scenarios undergo thermal simulation to generate data for machine learning analysis. The study primarily utilizes Random Forest (RF) as a new technique to estimate the heating and cooling loads in buildings, a critical factor in building energy efficiency. Following that, A random search approach is utilized to optimize the hyperparameters, enhancing the robustness and accuracy of the machine learning models employed later in the research. The RF algorithms demonstrate high performance in predicting heating and cooling loads (KWh/m2), contributing to enhanced building energy efficiency. The study underscores the potential of machine learning in optimizing building designs for energy efficiency.
