title An Adaptive Decision-Making Framework for Designing Material Behaviours

summary This paper describes an adaptive decision-making design framework for investigating the synergies between aesthetically-driven and performance-driven criteria, specifically in designing the material behaviour of an electroresponsive building envelope system. An immersive and interactive simulation environment developed in the C++ programming language provides a computational tool for testing the visual and energetic performance of a dynamic building envelope as it negotiates bioclimatic energy flows with participants’ aesthetic preferences and interactions. Experiments in bioresponsive feedback loops examine the impacts that user engagement and real-time energy performance feedback have on participants’ design choices. Preliminary results demonstrate that exposure to energy performance feedback and to the collective design choices of multiple users leads to adaptive decision-making that favours synergistic system performance with the potential for increased socio-ecological connections. Critically, this research provides new methods for supporting the design of emerging material behaviours for dynamic building envelopes that can negotiate multiple performance criteria.

title Thinking the BIM Way - Early integration of Building Information Modelling in education

summary Since Building Information Modelling as a technology depends on recognizing parts of the buildings as objects that can be simulated digitally, to prepare students to grasp the BIM way of thinking, educators can start introducing the concept early in the architectural curriculum without using the real tools. The researchers monitored the students' progress over a period of time while they were using different 3 dimensional CAD tools in several situations such as design studio visualization and construction document production until eventually the same group of students have been introduced formally to a real BIM tool. The research tries to establish a relationship between the pedagogical techniques and the success of the students to grasp what BIM is about and the development of their ability to use it fruitfully. Comparisons between their performances should shed the light on the best method to use in order to prepare students for the use of BIM.

summary Real estate development may benefit from a decision-support software system that is implemented with Building Information Modelling to perform Quadruple Net Value Analysis. Schemes may be created rapidly using BIM and parametric modeling. They may be assessed for economic, social, and environmental factors using spreadsheets and simulation software. They may be assessed for sensory value by using an immersive visualization system. The idea has been tested as a proof of concept in undergraduate and graduate design studios. It appears to be easy to use for students and effective in directing attention to the four factors and obtaining objective measurements.

summary This paper describes the design and testing of a mobile sensing kit for real-timeurban site analysis. It aims to contribute to a discussion on the importance ofsensing-based mapping of urban phenomena following our assertion that current delivery of urban analysis methodologies, with their emphasis on visuo-spatialanalysis only, fail to create maps that reflect the nuanced and layered interrelationships between the people and the physical environmental space they live in. In essence, the paper will bring to light the set up components and deployment of a mobile sensing kit that allows for usually mapped static invisible data (air quality, temperature, humidity) to be mapped as visible data. In other words, we want to explore how real-time geo-referenced data collection can enhance traditional data mapping and visualization methods enabling designers to understand better the urban space.

title Exploring Immersive Digital Environments

summary In contemporary architecture firms, most design drawings are done via use of 3D modelling software. This method requires advanced knowledge of the software in order to produce an accurate representation of space into the digital environment. The paper argues that conventional 3D visualization methods to design and analyse are restrictive to how well the user understands the space on a computer, as drawings are done ex-situ and without testing the design concept in-situ, hence there might be a level of disparity between the design and final fabrication. This is particularly a challenge when designing Urban Interaction Design concepts, as combinations of variables play a role in how the design will be received by the audience. Observing the design challenges for Urban Interaction Design and applying knowledge to architectural representation, potentially an alternative sketching process can be developed to alleviate the disparity between the conceptual design and post fabrication. This paper discusses an experimental process of using wireless spatial sensing devices to digitize physical spaces in real-time and to use on-the-spot analysis. In its conclusion the paper argues that this method enables the designer to gain advanced conceptual understandings of the intended space and thus make more informed decisions.

title Decision support for inner-city development - An interactive customizable environment for decision-making processes in urban planning.
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. 43-52

summary Re-densification of inner-city areas is a highly topical socio-political issue. In order to meet the increasing demand for centrally located living space, the cities have to amend building laws. At present, there are no analytical means of directly comparing and assessing different strategies and measures aimed at identifying the potential for internal development in specific urban quarters and learning about the consequences for the citizens. In this publication, we describe an interactive digital tool that monitors the key building codes and visualizes their effects on the urban structure in real-time, so that this can serve as an informed basis for debate and argumentation in the political decision-making and planning process, consequently supporting the development of re-densification strategies that are well-suited to their urban context.

summary This ongoing research describes a feedback loop procedure where physical inputs are used as the medium for offline robotic simulation. The purpose is to investigate the ability of industrial robots that are currently used in manufacturing processes to work in a flexible and productive manner whilst providing a continuous feedback loop between physical inputs and fabrication artifacts. In order to achieve this, a methodology is developed that involves the use of data acquisition devices to enable the transference of information from the physical to the digital environment and then to use this data as real-time parameters to control the robot's behaviour during fabrication. The aim is to achieve active involvement of robots in the manufacturing process to address complex construction issues and to ensure accuracy, a reduction in manufacturing defects and flexibility in the materials used. This investigation is accompanied by relevant experiments to exemplify the potential of control mechanisms to be used in prototyping case studies.

summary This paper introduces a counter-mapping attempt augmented by a Geoweb 2.0 platform in the context of two Belgian inner-city neighborhoods. The two aims of this project were to build a platform for the collective construction of a better understanding this dynamic super-diverse arrival environment and bring the various qualities and aspects of these super-diverse urban neighborhoods to foreground. In this study we report on the first results of this project which took place in Ghent and Brussels in 2014. Around 300 architecture students registered, interpreted and geocoded visible signs along preconceived tracks by means of a Geoweb 2.0 platform. Through field observations and interviews, the students created dynamic and interactive maps. We found that the large-scale mapping through Geoweb 2.0 makes it possible to discern different layers of use in arrival neighborhoods. These layers referred to different population groups which continuously have to negotiate each other's presence. Furthermore, the platform created the possibility to effectively and efficiently combine student fieldwork with online and offline lectures and offered students the opportunity to comment on, peer-review and learn from each other's insights. The findings will serve as an alternative information resource in the forthcoming Master's thesis graduation design studio which will be led by the first author.

title A Thousand BIM: A rapid value-simulation approach to developing a BIM tool for supporting collaboration during schematic design
source International Journal of Architectural Computing vol. 12 - no. 1, 47-60
summary The purpose of this study is to develop a BIM-based plug-in that is able to assist a collaboration among heterogeneous professionals. The tool will enable them to communicate in the same language, articulate criteria and priorities in multiple perspectives, and to share rapidly simulated evaluations of schematic design variations. Among many barriers that block collaborations among professionals, a quintessential barrier in the building and design industries may be epistemological rather than physical. The professionally different ways of thinking, expertise, values, and priorities can be a block on the collaborative development process of architectural design projects. This paper takes the example of the relationship between developers and architects, who tend to have different evaluation criteria. A real-time value simulation tool is introduced as a means to generate possible building typologies on a given project site, with computation of expected total values expressed in simple financial terms.

summary The main purpose of this research is to introduce and verify selected advanced computational methodologies operating with agent-oriented approach that are applicable within the framework of emergent urban design strategies in early stages of zoning proceedings. The aim is to demonstrate that speculative matter of the phenomenon of emergence in terms of design thought driven by computational models can also be applicable within real existing urban conditions. The research concurs previous researches in the field of urban pre-reconfigurations in the selected city environments. It concentrates on developing a simulation model as an analytical and generative instrumental platform for architects in early phases of urban design and synthetizes accumulated computational advancements based on agent-oriented approach.

title Dynamic 3D-Sketching
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. 107–116
summary Sketching by hand is without doubt – alongside building models – the most common tool that architects employ when designing. A disadvantage of the sketch is, even if it is a perspective drawing, that it is a purely two-dimensional planar representation of a three-dimensional product: the three-dimensional impression that the sketch communicates is a product of the viewer’s imagination. Digital modelling tools on the other hand support the creation of three-dimensional content but fall short in their ease of handling: their complexity and potentially unintuitive operation hinder rather than support the design process. Taking this discrepancy as a starting point, the presented system details the development and prototypical implementation of a dynamic 3D-sketching tool. The underlying core idea is to create a seamless connection between a perspective hand-sketch and the corresponding digital 3D-model in order to benefit from the advantages of hand sketching as a design tool and computer maintained 3D models. The system allows the designer to work as usual, visualizing his or her thoughts using perspective sketches. The user sketches on a touchscreen surface. The 2D drawing is automatically interpreted and converted into a system of 3D lines, surfaces and volumes in real-time.

summary In decades past, the architect was the master-builder with hands-on craftsman experience to design and direct the various trades in the construction of the building. The role of digital design, computation methodologies and processes are poised to transform how we think and craft architecture to deliver today's built environment. Digital crafting methods in today's thinking process for a designer/builder/manufacturer are affecting the delivery of buildings as a final product with aspiration to create rich sensory and habitable environments. ASCAAD 7th Conference theme explores the linkages among digital design process thinking, constructability, the digital manufacturing process and their impact on the practice of architecture, engineering and construction. ASCAAD society has invited academics, researchers and professionals to join and contribute to the debate on the use of Computer-Aided Architectural Design and Information Technology and how the use/ implementation would support and lead to innovative concepts, tools, systems and products on architectural, Urban/City/ regional planning, and building science levels.

summary Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

summary The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Passive and active building skins are developed using shape memory alloys and pneumatic actuators through investigations of smart systems that integrate smart materials and smart geometries. Nitinol springs are integrated in tensegrity systems to actuate the adaptive behaviour, which forms the passive roof system. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

summary This paper introduces a new spatial analysis methodology based on visibility graphs. Through various design elements architects can create configurations where our visual field and the relations of spaces can be challenged in a combinatorial game beyond the easily accessible and understandable boundaries of the environment. This research explores the trans-spatial architectural elements, transparencies and projected realities that playfully challenge visibility, permeability and accessibility in built environment. The paper presents the computational problem of analysing spaces that include 'augmented visibilities' and areas with 'inaccessible but visible' locations, where dislocated multi-dimensional overlaps frequently occur. Furthermore, proposes a new 'mixed-directionality graph structure' and the definition of 'Augmented Visibility Graph Analysis' (AVGA) as a new spatial analysis methodology. AVGA overcomes limitations of current visibility graph analysis theories and allows the analysis of architectural and urban space that includes visuo-spatial overlaps, hybrid configurations and multi-dimensional information. Finally, a series of mathematical graph analysis measures and test cases associated with observations and experimental data from real spaces is presented in order to demonstrate AVGA.

title Comparison of Partitioning Methods for Estimating the Layout of Green Spaces
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. 873–882
summary The urban green space positively affects the quality of the environment and urban life. To estimate the layout of urban green spaces, especially to describe the real difference of regional properties, the influenced zone of each green space should be identified firstly. The influenced zone can be used to quantitatively analyse the difference of regional environmental quality. The identification of the influenced zones of green spaces actually is a problem of space partitioning. The study compared three methods mostly used in space partitioning. The regular grid is a most common partitioning method. It is easy to use, but cannot link the grid with green space separately. Voronoi algorithm is a constructive method which partitions the urban space based on each green. Another approach is the application of gravity models, which assumed analogies between human behaviour and Newtonian gravity laws. The gravity model could calculate the probabilities of residents to choose the green space and partition the urban space. In the comparison of these three methods, we conclude that the gravity model can take more characteristics of the green space as the calculating parameters. The gravity model is a better method to estimate the layout of urban green spaces.
