title	Surface Dynamics: From dynamic surface to agile spaces
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. 39-48
summary	Behavior, adaptation and responsiveness are characteristics of live organisms; architecture on the other hand is structurally, materially and functionally constructed. With the shift from ‘mechanical’ towards ‘organic’ paradigm (Mae-Wan Ho, 1997) attitude towards architectural adaptation, behavior and performance is shifting as well. This change is altering a system of reference and conceptual basis for architecture by suggesting the integration of dynamics – dynamics that don’t address kinetic movement only but include flows of energies, material and information. This paper presents an ongoing research into kinetic material system with the focus on non-mechanical actuation (shape memory alloy) and the structural and material behavior. It proposes an adaptive surface capable of altering its shape and forming small occupiable spaces that respond to external and internal influences and flows of information. The adaptive structure is developed as a physical and digital prototype. Its behavior is examined at a physical level and the findings are used to digitally simulate the behavior of the larger system. The design approach is driven by an interest in adaptive systems in nature and material variability (structural and functional) of naturally constructed materials. The broader goal of the research is to test the scale at which shape memory alloy can be employed as an actuator of dynamic architectural surfaces and to speculate on and explore the capacity of active and responsive systems to produce adaptable surfaces that can form occupiable spaces and with that, added functionalities in architectural and urban environments.

title	Controlling Kinetic Cladding Components in Building Façades: A Case for Autonomous Movement
doi	https://doi.org/10.52842/conf.caadria.2014.129
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. 129–138
summary	"The movement of building façade cladding is usually used to control buildings’ exposure to environmental conditions such as direct sunlight, noise and wind. Until recently, technology and cost constraints allowed for only limited types of façade cladding movement. One of the main restrictions stemmed from the limitations that architects face in designing and controlling movement scenarios in which each façade or cladding element moves autonomously. The introduction of parametric design tools for architectural design, combined with the advent of inexpensive sensor/actuator microcontrollers, made it possible to explore ways to overcome this limitation. Autonomous movement of building façade cladding elements has several potential benefits. One of the main feasible advantages of this type of movement is that it can deal with changing external and interior local conditions in different parts of the façade by individually controlled movement, by preceding reaction or flock behaviour. Thus, it can increase significantly the performance of the building façade. This paper presents new results from an ongoing research study that is examining the potential of autonomous movement of façade cladding elements. It compares the environmental performance of centrally controlled kinetic façade elements and a prototypic façade made of autonomously controlled elements.

summary	Skin is the primary shield between our body and its surroundings. It protects the body from the harmful environmental effects like dehydration and radiation from intense sunlight. Likewise, the outer layer, or skin of a building has the same function of protecting its inhabitants against the external elements. This research is a part of a larger investigation into geometrical patterning and layering of facades as an effective intervention between the outdoor space and the indoor environment to regulate the conditions for occupant thermal comfort. This paper reports on exploration of an approach for measurement, evaluation and feedback in the design workflow through a mixed digital -physical simulation platform (MDPS) based on the objectives of the larger study. For this purpose, it introduces a new way of analyzing thermal performance of double skin facades by using temperature sensors, Arduino, post visualization with MATLAB and digital energy simulation. The main aspects of this proposed workflow is the design of a thermal performance feedback loop as an integral part of the process of geometrical patterning design for façade.

title	The BIM based Responsive Environmental Performance Design Methodology
source	SIGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay- Montevideo 12,13,14 November 2014, pp. 120-125
summary	The concept of “families” lies in the core of internal data structure in Building Information Modeling (BIM). The elements of this modeling platform are all associated with each other as parts of the “families”, independent of their geometrical structure, materiality, parametric dependencies or their physical connection to other elements. Through the associations introduced among the parameters of the ‘families’ members, this study aims at establishing a methodology for a multi-objective evaluation of the environmental performance of the building as an organism. The methodology is founded on a system of different values and weights attributed to the parameters of the families members which are adjusted and fine-tuned through a series of iterations, thus affecting the overall building performance towards an optimum goal. The performance evaluation method used in the “families” methodology is not limited to the individual assessment of the environmental performance objectives or to an integrated multi-objective weighting mechanism; as an overall evaluation platform it checks and balances the individual characteristics of the system not as static conclusive results but as dynamic criteria intended to guide the overall design and building process. The importance of this paper lies in the construction of a concrete methodological set of tools for the assessment of the environmental performance of the building. It will lead the way in independent research in the field of architectural design and the development of ecological thinking and building in China.

title	Structural, Deployable Folds - Design and Simulation of Biological Inspired Folded Structures
source	International Journal of Architectural Computing vol. 12 - no. 3, 243-262
summary	This paper presents a concept of folding as a form-generator for a structural system that allows the ability to deploy large spanning structures. The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modeling process that allows structural performance evaluation of different types of the same origami family in order to optimize the geometry for a given scenario. The workflow between scripting based form generation - within Rhinoceros and Excel - and LS-DYNA is presented in detail. Additionally, within the context of an architectural project we discuss the question of scalability from a thin microstructure to a thickened roof structure.

title	Evolutionary Optimisation of Semitransparent Building Integrated Photovoltaic Facades
source	International Journal of Architectural Computing vol. 12 - no. 1, 81-100
summary	The optimisation of semi-transparent building integrated photovoltaic facades can be challenging when attempting to find an overall balance performance between conflicting performance criteria. This paper presents a three-phase design optimisation method that maximises overall electricity savings generated by these types of facades by simulating the combined impact of electricity generation, cooling load, and daylight autonomy. Two demonstrations are performed, with the difference being that the second demonstration uses an enhanced model for calculating daylight savings that takes into account the use of blinds to counteract glare. For both demonstrations, the three-phase optimisation method significantly reduces optimisation run times. Comparing the design variants evolved by the two demonstrations, the use of the enhanced daylight savings model results in a total electricity savings that is more accurate but in terms of visual differentiation, the difference between the optimized design variants is relatively small.

summary	This work describes a design methodology to minimize direct solar incidence in facades, exploring the shape of brise-soleil. The methodology correlates parametric design and evolutionary algorithm, through the integration of computational tools. At first, are established shade’s shape variable and restrictions, through the Rhinoceros software and Grasshopper plug-in. Subsequently, the shape is studied to minimize the sunlight incidence through the genetic platform ‘Galapagos’ and the simulation software ‘Ecotect’. The results indicate the relevance between the parametric design and the evolutionary algorithms during the project process, reducing the time in researching for optimized solutions.

title	Measurability of Loos' rejection of the ornament - Using box-counting as a method for analysing facades
doi	https://doi.org/10.52842/conf.ecaade.2014.1.495
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 495-504
summary	As evidence from recent years has demonstrated, box-counting provides an objective fractal analytical method to evaluate the visual complexity of architecture. This paper for the first time explores the potential of box-counting with regard to the work of the Viennese architect Adolf Loos (1870-1933). Loos is seen as the pioneer of modern architecture, as someone who anticipated the International Style. This impression derives from his resentments towards the ornament, expressed especially in his texts. However, Loos did not reject ornamentation in general. Thus, the group of smooth plastered facades provides a narrowed view on his overall architectural concept. A more differentiated view on Loos' oeuvre is not new; however, the author further develops the possibilities of describing facades geometrically by using an implementation of the fractal analytical method, especially created for facades. This paper not only focuses on the possibility of grouping facades with similar characteristic values, but considers other aspects of Loos' design such as space as well.

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	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	Towards a BIM-Based Energy Rating System

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. 285–294
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.

title	Learning to be a Vault - Implementing learning strategies for design exploration in inter-scalar systems
doi	https://doi.org/10.52842/conf.ecaade.2014.1.381
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 381-390
summary	Parametric design models enable the production of dynamic form, responsive material assemblies, and numerically and geometrically analytical feedback. The value potential for design produced through the procedural transformation of input parameters (or features) through algorithmic models has been repeatedly demonstrated and epistemically refined. However, despite their capacity to improve productivity and iteration, parametric models are nonetheless prone to inflexibility and reduction, both of which obscure processes of invention and discovery that are central to an effective design practice. This paper presents an experimental approach for the application of multiple, parallel computational design modelling strategies which are tested in the production of an inter-scalar model array that synthesises design intent, the simulation of material behaviours, performance-driven adaptation, and open-ended processes of discovery and categorical description. It is particularly focused on the computational potentials embedded in interdependent applications of simulation and machine learning algorithms as generative and descriptive drivers of form, performance, and architectural quality. It ultimately speculates towards an architectural design modelling method that privileges open model topologies and emergent feature production as critical operators in the generation of flexible and adaptive design solutions.

summary	Existing typologies of emergency housing rely heavily on conventional designs, materials and labor-intensive construction methodologies, which in post-disaster environments place large amounts of strain on the surrounding communities, material manufacturers and financial systems. With ever more unpredictable environmental conditions, should our new housing prototypes not also have the ability to simultaneously adapt to rapidly changing environmental conditions? This paper investigates the potential of developing a new typology of rapidly deployable emergency housing prototypes through the creation of a system which relies on embedded design intelligence, advanced fabrication and adaptable systems, rather than attempting to make existing building systems smarter.

summary	The last decade have seen substantial calls and increasing pressure for developing an integrated design teaching framework, where sustainability is an imperative priority. This paper focuses on presenting a taxonomy of the main challenges encountered within the educational domain, in the attempt to reach an effective integration. The paper also presents a set guidelines to address and try to resolve the noted challenges. As the use of Building Performance Simulation (BPS) applications is a central approach in this process aiming to reach energy efficient buildings, the paper focuses on the shortcomings noted as a result of the use of these applications in the design studios, with particular emphasis on the thermal and lighting aspects of the simulation. The taxonomy presented is a summary of the findings from literature review, as well as the surveys results which were part of the author's research project discussed in the paper.

summary	This paper reflects a collaborative, research led design project, aiming to explore the potentials offered by incorporating parametric / generative tools and performative lighting simulation software in order to design and fabricate a small pavilion for the School of Architecture. The Deceptive Landscape pavilion was designed in the framework of a masters level, research led, and collaborative design studio. During its intense 12 weeks schedule, student teams were asked to explore and apply generative / parametric tools such as Rhino and Grasshopper, in order to design and later construct a small pavilion, with a theme of their choice. In addition, each team was asked to optimise their design proposal by embedding environmental software plug-ins (e.g. DIVA for Rhino) in their design process, thereby aiming to re-inform their parametric models and set performance targets. Finally each team was expected to propose a file to factory fabrication technique, following all constrains of a limited, predetermined budget. The most convincing and consistent proposal, was then chosen for fabrication. The finalised project serves as verification of the effectiveness of the design system and teaching methods used.

title	Comparison between Genetic Optimization and Heuristic Methods for Prioritizing Infrastructure Rehabilitation Programs
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. 175-182
summary	In recent years, infrastructure rehabilitation has been in the focus of attention in North America and around the world. A large percentage of existing infrastructure assets is deteriorating due to harsh environmental conditions, insufficient capacity, and age. Due to stringent budget limits, however, asset management systems become important to assess the life cycle performance of various assets, and accordingly prioritize the assets for rehabilitation purposes. While many asset management systems have been introduced in the literature, almost no studies have compared the effectiveness of their asset prioritization methods. This paper presents an extensive comparison between heuristic and optimization methods for prioritizing large-scale rehabilitation programs, under budget constraints. The paper first introduces different life cycle cost analysis (LCCA) formulations for three case studies obtained from the literature related to buildings, pavements, and bridges. Based on extensive experiments with the three case studies and on different network sizes, heuristic techniques proved its practicality for handling various network sizes. The performance of genetic optimization, on the other hand, was more efficient on small-scale networks but showed steep degradation in performance with large-scale problems. This research can be beneficial to municipalities and asset managers and can help them design efficient methods to sustain the safety and operability of the civil infrastructure, with least cost.
