title	Solar Form Finding: Subtractive Solar Envelope and Integrated Solar Collection Computational Method for High-Rise Buildings in Urban Environments
doi	https://doi.org/10.52842/conf.acadia.2017.212
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 212-221
summary	Daylight standards contribute significantly to the form of buildings and the urban environment. Direct solar access of existing and new buildings can be considered through the use of solar envelope and solar collection isosurface methods. The first determines the maximum volume and shape that new buildings cannot exceed to guarantee the required solar rights on existing surrounding facades. The latter predicts the portion of facades of new buildings that will receive the required direct sunlight hours in urban environments. Nowadays, environmental design software based on the existing methods permits the generation of solar envelopes and solar collection isosurfaces to use in the schematic design phase. Nevertheless, the existing methods and software present significant limitations when used to design buildings that must fulfil the Estonian daylight standard. Recent research has successfully developed computational workflows based on the existing methods and available tools to tackle such shortcomings. The present work uses the findings to propose a novel computational method to generate solar envelopes and integrate solar collection analysis. It is a subtractive form-finding method that is more efficient than the existing additive methods and other recent workflows when it is applied to high-rise buildings in fragmented urban environments. The tests performed show that the new method permits the realisation of compliant and larger solar envelopes, which furthermore embed formal properties. The objective of the research is to contribute to the development of computational methods and tools to integrate direct solar access performance efficiently into the design process.

title	An experimental design framework for the personalization of indoor microclimates through feedback loops between responsive thermal systems and occupant biometrics
source	International Journal of Architectural Computing vol. 15 - no. 1, 54-69
summary	How can building technologies accommodate different and often conflicting user preferences without dissolving the social cohesiveness, intrinsic of every architectural intervention? Individual thermal comfort has often been considered a negligible sensorial experience by modern heating and cooling technologies, and is often influenced by large-group norms. Alternatively, we propose that buildings are repositories of indoor microclimates that can be realized to provide personalized comfort, to create healthier environments, and to enhance the attributes of architectural interventions into haptic dimensions. In response, the goal of this study is to characterize an experimental framework that integrates responsive thermal systems with occupants’ direct and indirect experience, which includes stress response and biometric data. A computational model was used up to inform and analyze thermal perception of subjects, and later tested in a responsive physical installation. While results show that thermal comfort assessment is affected by individual differences including cognitive functions and biometrics, further computational efforts are needed to validate biometric indicators. Finally, the implications of personalized built environments are discussed with respect to future technology developments and possibilities of design driven by biometric data.

title	Design and Additive Manufacturing of Lattice-based Cellular Solids at Building Scale

summary	The amounts of material that is being extracted, harvested and consumed in the last decades is increasing tremendously and bringing to the serious problem of resource scarcity. As a direct consequence to this claim, designers are challenged to rethink architecture and develop new ways of confronting with materials. A potential answer to this problem is the exploration of computational logics for architectural design and fabrication inspired by the observation of biological formations. This work explores how the biological model of bone microstructure can be applied to a larger scale architecture that is structurally responsive, by means of computational design and Additive Manufacturing.

summary	This paper proposes a design and fabrication approach based on the conceptualization of architectural formations as spatial assemblies of discrete building blocks to be aggregated through custom robotic procedures. Such strategy attempts to create synergies between different technological methods and to define a new and open design space where discrete design, serial prototyping and robotic assembly can be exploited to create complex reconfigurable structures. With the aim to allow users to explore the field of discrete geometries for architectural application without need for prior programming knowledge, we developed a software framework for representing and designing with discrete elements, different digital fabrication techniques integrated with conventional production processes for serial prototyping of repetitive units, and custom robotic fabrication routines, allowing a direct translation from aggregated geometry to assembly toolpath. Together these methods aim at creating a more direct connection between design and fabrication, relying on the idea of discrete elements assembly and on the parallel between modular design and modularized robot code generation.

summary	"Architectural harmony with natural systems - including natural light - is essential to the wellbeing of building occupants" (Shrum, 2017). A preliminary study of existing daylight recommendations in standards and sustainability certificates, applied in Denmark, revealed a neglectance of the importance of receiving direct sunlight in dwellings. The qualities of sunlight were defined through a modest qualitative analysis, resulting in five parameters: Sunlight Hours, Winter Sun, Morning Sun, Golden Hours and Magic Moments. These were defined as specific time periods supported by research on the visual and non-visual effects on well-being. The parameters were subsequently translated into a parametric analysis tool, using design application Rhinoceros 3D and elaborating on a new usage of the design software Ladybug Tools. This analysis tool is predicted to be of high use to identify problematic apartments in the architectural design phase, to compare different design proposals and to meet the individual needs of new occupants.

title	Streamlining the Modelling to Virtual Reality Process - Semi-Automating Mesh Quadrangulation and UV Unwrapping for Grasshopper.
doi	https://doi.org/10.52842/conf.caadria.2017.053

summary	Visualisation in architecture often involves a transition between different modelling programs. This is done in order to be able to manually prepare and repair three-dimensional models for visualisations such as renders and VR simulations. In this paper the development of a direct link between a three-dimensional modelling platform and a Virtual Reality (VR) Engine is investigated. This is researched through the generation and manipulation of clean quad mesh topology, UV mapping and UV texture map creation. Through a reiterative process, all possible solutions for improved quad mesh topology for doubly curved surfaces are explored. The resulting clean quad mesh improves the usability of the model and application of textures to accurately simulate a real material. In parallel, the development of a UV unwrapping and UV map creation process was investigated to enhance the texturing process inside the same architectural modelling platform. The overall system was developed as an advanced tool for semi-automating and streamlining the process between modelling and VR simulation. The paper concludes with the limitations of the process and points out to future research to improve speed and quality as well guides to where future testing and experiments should be further investigated and applied.

title	Furniture Design Using Custom-Optimised Structural Nodes
doi	https://doi.org/10.52842/conf.caadria.2017.841

summary	Additive manufacturing techniques and materials have evolved rapidly during the last decade. Applications in architecture, engineering and construction are getting more attention as 3D printing is trying to find its place in the industry. Due to high material prices for metal 3d printing and in-homogenous material behaviour in printed plastic, 3D printing has not yet had a very significant impact at the scale of buildings. Limitations on scale, cost, and structural performance have also hindered the advancement of the technology and research up to this point. The research presented here takes a case study for the application of 3D printing at a furniture scale based on a novel custom optimisation approach for structural nodes. Through the concentration of non-standard geometry on the highly complex custom optimised nodes, 3D printers at industrial product scale could be used for the additive manufacture of the structural nodes. This research presents a design strategy with a digital process chain using parametric modeling, virtual prototyping, structural simulation, custom optimisation and additive CAD/CAM for a digital workflow from design to production. Consequently, the digital process chain for the development of structural nodes was closed in a holistic manner at a suitable scale.

title	Simulation of Sound Diffusion Patterns of Fractal-Based Surface Profiles
doi	https://doi.org/10.52842/conf.acadia.2017.052
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 52-61
summary	Acoustical design is one of the most challenging aspects of architecture. A complex system of competing influences (e.g., space geometry, size, proportion, material properties, surface detail, etc.) contribute to shaping the quality of the auditory experience. In particular, architectural surfaces affect the way that sound reflections propagate through space. By diffusing the reflected sound energy, surface designs can promote a more homogeneous auditory atmosphere by mitigating sharp and focused reflections. One of the challenges with designing an effective diffuser is the need to respond to a wide band of sound wavelengths, which requires the surface profile to precisely encode a range of detail sizes, depths and angles. Most of the available sound diffusers are designed to respond to a narrow band of frequencies. In this context, fractal-based surface designs can provide a unique opportunity for mitigating such limitations. A key principle of fractal geometry is its multilevel hierarchical order, which enables the same pattern to occur at different scales. This characteristic makes it a potential candidate for diffusing a wider band of sound wavelengths. However, predicting the reflection patterns of complicated fractal-based surface designs can be challenging using available acoustical software. These tools are often costly, complicated and are not designed for predicting early sound propagation paths. This research argues that writing customized algorithms provides a valuable, free and efficient alternative for addressing targeted acoustical design problems. The paper presents a methodology for designing and testing a customized algorithm for predicting sound diffusion patterns of fractal-based surfaces. Both quantitative and qualitative approaches were used to develop the code and evaluate the results.

title	Functionally Graded Architectural Detailing using Multi-Material Additive Manufacturing
doi	https://doi.org/10.52842/conf.caadria.2017.427
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 427-436
summary	The paper presents a future architectural detailing strategy enabled by the design of functionally graded materials (FGM). In specific, our proposal suggests the possibility of removing mechanical fasteners and adhesives from joint details. This is achieved by combining the principles of interlocking joineries found in traditional timber structures and current Multi-Material Additive Manufacturing (MMAM) technology to materialise FGMs. FGM belongs to a class of advanced materials characterised by variation in properties as the dimension varies by combining two or more materials at a microscopic scale (Mahamood et al. 2012). FGM is ubiquitous in nature and, when properly designed, can exhibit superior performance characteristics compared to objects comprised of homogeneous material properties. With the aim of developing interlocking details with improved performance, reliability, and design flexibility, we focus on controlling material stiffness, joint fitting, and geometry through the design of the microscopic material layout. A case study design will be presented to illustrate the process.

summary	This study experiments a process of production of tactile representations of architectural elements of a nineteenth century mansion, house to a university museum: Museu do Doce, Pelotas, RS. The Museum uses the concept of Universal Design to guide its direct and/or mediated communication solutions. The house is distinguished by ceilings of ornamental stuccoes, evidently perceived only by the sense of sight. To describe them, a set of representations is being produced, using 3D scanning and digital fabrication technologies, using formal decomposition, and different scales, to construct a narrative to be understood by touching.

title	From Envelope to Layout - Buildings Massing and Layout Generation for Solar Access in Urban Environments
doi	https://doi.org/10.52842/conf.ecaade.2017.2.431

summary	The use of daylight for the inhabitants health and comfort purposes and for the energy efficiency of buildings influences significantly the shape and outlook of urban environments. The solar envelope and solar collection surface are methods to define the massing of buildings for direct solar access requirements. They have been recently improved to be used in the design of buildings in relation to the Estonian daylight standard. Nevertheless the solar collection method can be applied only to single buildings with simple shape. The present research investigates the direct solar access performance of building clusters with multiple layouts in different urban areas in the city of Tallinn. Result show that different patterns perform in significant different ways whereas the same cluster types have the best and the least performances in all the cases.

title	Solar Collection Multi-isosurface Method: Computational Design Advanced Method for the Prediction of Direct Solar Access in Urban Environments

summary	Direct solar access and daylight requirements contribute significantly when it comes to shaping the layout and appearance of contemporary cities. Urban planning regulations in Estonia set the minimum amount of direct solar access that existing housing has the right to receive and new premises are required to get when new developments are built. The solar envelope and solar collection methods are used to define the volume and shape of new buildings that allow the due solar rights to the surrounding buildings, in the case of the former, and the portion of the own façades that receive the required direct solar access, in the case of the latter. These methods have been developed over a period of several decades, and present-day CAAD and environmental analysis software permits the generation of solar envelopes and solar collection isosurfaces, although they suffer from limitations. This paper describes an advanced method for generating solar collection isosurfaces and presents evidence that it is significantly more efficient than the existing method for regulation in Estonia’s urban environments.

title	Decoding Parametric Design Data - Towards a Heterogeneous Design Search Space Remix
doi	https://doi.org/10.52842/conf.caadria.2017.117
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 117-126
summary	Designers or Non-Designers are not able to effectively access, view, search, discover, collect, reuse, remix and share parametric design data (PDD) for either professional or educational purposes. PDD here refers to the meta-data of 3D models generated by visual dataflow modelling software packages used in CAD/CAM industry. This ineffectiveness is a direct consequence of the deliberately proprietary nature of most PDD file formats and the restricted use within their respective desktop-based software environments. This paper presents an initial software prototype capable of automating the process of decoding a commonly used PDD file format and then re-encoding it with new set of metrics to facilitate multiple PDD searchability, comparability and interoperability, via an integrated web interface querying a design data repository. All PDDs are conceptualized as genealogies of numerical or geometric transformations and explicitly encoded with a graph-based data structure. The goal is to eventually learn from its own big data and begin to artificially generate novel PDDs heterogeneously.

summary	This paper aims to highlight the ways in which Shape Grammar inductive reasoning can analyze and represent design knowledge in a tacit environment. Deductive Shape Grammar has effectively examined designs from the past, where access to the artifacts’ authors is not possible. However, in a condition where access to the craftsperson and the making process is possible, there is an opportunity to induce design grammar from the evidence on-site. Nevertheless, in such contexts, direct access to the craftsperson does not necessarily mean that access to their design knowledge is straightforward, as reflected in our case study, Passura: a Traditional Glyph in Toraja, Indonesia. In this article, the formulation of inductive Shape Grammar is provided, and applications on the tacit environment are discussed.

summary	Even though interactive (Offermans et.al., 2013), adaptive (Viani et.al., 2017), and self-optimizable (Sun et.al., 2020) lighting systems are becoming readily available, designing system automations, and evaluating their impact on user experience significantly challenges designers. In this paper we demonstrate the use of a gaming engine as a platform for designing, simulating, and evaluating autonomous smart lighting behaviors. We establish the Human - Lighting System Interaction Framework, a computational framework for developing a Light Sculpting Engine and for designing occupant-system interactions. Our results include a. a method for combining in real-time lighting IES profiles into a single ‘combined’ profile - b. algorithms that optimize in real-time, lighting configurations - c. direct glare elimination algorithms, and d. system energy use optimization algorithms. Overall, the evolution from designing static building components to designing interactive systems necessitates the reconsideration of methods and tools that allow user experience and system performance to be tuned by design.

summary	Considering the outdoor environment at the initial stage of design process plays a significant role on future building performance. Augmented Reality (AR) technology applied in this research can integrate real world building morphology information and virtual world ventilation information seamlessly that rapidly and directly provides designers information for observation and evaluation. During the case study of "2017 Shanghai DigitalFUTURE" summer workshop, a research on augmented reality technology based wind environment visualization was carried on. The achievement with an application software not only showed the geometric information of the real world objects (such as buildings), but also the virtual wind environment has displayed. Thus, these two kinds of information can complement and superimpose each other. This AR technology based software brings multiple synthetic together, which can (1) visualize the air flow around buildings that provides designers rapid and direct information for evaluation; (2) deal with wind-environment-related data quantitatively and present in an intuitive, easy-to-interpret graphical way; and (3) be further developed as a visualization system based on built-in environments in the future, which contributes to rapid evaluation of a series of programs at the beginning of the building design.

title	Development of parametric CAAD models for the additive manufacturing of scalable architectural models

summary	Architecture models are an essential component of the development process and enable a physical representation of virtual designs. In addition to the conventional methods of model production using the machining of models made of wood, metal, plastic or glass, a number of additive manufacturing processes are now available. These new processes enable the additive manufacturing of architectural models directly from CAAD or BIM data. However, the boundary conditions applicable to the ability to manufacture models with additive manufacturing processes must also be considered. Such conditions include the minimum wall thickness, which depends on the applied additive manufacturing process and the materials used. Moreover, the need for the removal of support structures after the additive manufacturing process must also be considered. In general, a change in the scale of these models is only possible at very high effort. In order to allow these restrictions to be adequately incorporated into the CAAD model, this contribution develops a parametrized CAAD model that allows such boundary conditions to be modified and adapted while complying with the scale. Usability of this new method is illustrated and explained in detail in a case study. In addition, this article addresses the additive manufacturing processes including subsequent post-processing.

title	3D Representations of Cities in Video Games as Designed Outcomes

summary	The following paper proposes a way of reading and systematizing 3d representations of cities in video games. These representations are the result of a complex design problem not solely limited to 3d graphical representations. In fact, every 3d city is a designed artefact, an outcome of a design process that shares many common points with the architectural design process. Four main characteristics of 3d cities in videogames have been identified and described, namely: interaction/gameplay, narrative, architectural and urban representations, and graphical representations. The study of 3d cities in video games can also let us reflect on and improve our real cities. This piece of writing is part of a larger project that intends to investigate aspects of video games that can bring innovative approaches and theories into architecture and related fields. A further aim of the work is to raise interest and awareness on the topic and generate further discussions.

summary	In continuation of our previous research (Hussein, et al., 2017), this paper examines the kinetic transformable spatial-bar structures that can alter their forms from any free-form geometry to another, which can be named as Free-form transformable structures (FFTS). Since 1994, some precedents have been proposed FFTS for many applications such as controlling solar gain, providing interactive kinetic forms, and control the users' movement within architectural/urban spaces. This research includes a comparative analysis and a critical review of eight FFTS precedents, which revealed some design and technical considerations, issues, and design and evaluation challenges due to the FFTS ability to deliver infinite unpredictable form variations. Additionally, this research presents our novel algorithmic framework to design and evaluate the infinite form variations of FFTS and an actuated prototype that achieved the required movement. The findings of this study revealed some significant design and technical challenges and limitations that require further research work.
