summary	In the modern urbanization process, urban planners create rules to define urban form and composition of blocks which are greatly impacted by the road network. This research paper proposes a "city generator", as an urban design toolkit for urban designers to make prototypes of large new town planning and reimagination of city generation. The generator aims to translate planning regulations into three-dimensional urban form and provide users with efficient and intuitive design iterations. Moreover, our generator emphasizes consistency in generation across scales. From a single block to a district, they can be produced in one operation without losing details. Finally, the generator provides a great degree of freedom for users to manipulate, including three aspects - road generation, density mapping and building form. Because of the flexibility of input parameters, generated models can be a rigid urban grid or an organic pattern, which can highly satisfy urban designer's expectations and imagination.

title	Integrated Architectural and Environmental Performance-Driven Form-Finding - A teaching case study in Montreal
doi	https://doi.org/10.52842/conf.ecaade.2021.2.105

summary	The proposed paper presents the methodology and the outcomes of an intensive conception studio taught by the authors at the School of architecture of the University of Montreal having as objective the introduction of 3rd year architecture students to environmental evaluation and optimization techniques linked by the parametric design and the generative creation of architectural object. As opposed to mostly analysis-based approaches, an integration with architectural and urban design concepts was considered to be a more efficient method to initiate architecture students in environmental performance-driven design. The novelty of the course lays in the development of an integrative teaching method having as educational goals the development of environmental analysis skills, the creative use of digital tools, the conception of a coherent optimization process and the ability to represent a performance-driven design process.

title	Applying Urban Parametricism in the Design of Dynamic Neighborhoods

summary	Neighborhoods are considered basic spatial units of an urban area. Their forms have complex and hierarchical structures that contain building layouts, street segments, street networks and etc.. The traditional ways of computationally producing neighborhoods have proven incompetence. Some of these conventional ways focus on the morphological approaches, but they do not include all urban features. Meanwhile, other models that can design urban features have limited formulation flexibility. Besides the absence of dynamic generation behavior as they don’t use parametric techniques. They lack interactivity with the surroundings as they don’t use streets as the main generator of neighborhoods. Additionally, they don’t have the ability of automatically analyzing the site. Other models are generated for a specific location and miss the interactivity with other sites. This study implements parametric techniques to generate an urban model with wide design varieties. Furthermore, the model has dynamic morphological behavior, capable of interacting with the designer's modifications. This study focuses on the streets and grid as the dominant element of neighborhoods. The study also presents a predefined function in the scripting process. The model also proposes a python switcher to allow easy accessing all the inputs. Also, the research converts the elements to be more interactive, responsive, flexible, and dynamic. Therefore, all the neighborhood elements are simultaneously created according to user requirements. The study method is divided into three stages: Decomposition, Formulation, Modeling, and evaluation. Each process is defined with its tools, inputs, and parameters.

title	Territories Made by Measure: The Parametric as a Way of Teaching Urban Design Theory
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 494-506
summary	Design tools like Grasshopper are often used to either generate novel forms, to automate certain design processes or to incorporate scientific factors. However, any Grasshopper definition has certain assumptions about design and space built into it from its earliest genesis, when the initial algorithm is set out. Correspondingly, implicit theoretical positions are built into definitions, and therefore its results. Approaching parametric design as a question of architectural, landscape architectural or urban design theory allows the breaking down of traditional boundaries between the technical and the historical or theoretical, and the way parametric design, and urban design history & theory, can be conveyed in the teaching environment. Once the boundaries between software and history & theory are transgressed, Grasshopper can be a way of testing the principles embedded in historical designs and thus these two disciplines can be joined. In urban design, there is an inherent clash between an ideal model and existing urban geography or morphology, and also between formal (qualitative) and numerical (quantitative) aspects. If a model provides a necessary vision for future development, an existing topography then results from the continuous human and natural modifications of a territory. To explore this hypothesis, the “Urban Design Representation” subject in the Master of Urban Design program at the University of Cape Town taught in 2017 & 2018 was approached “parametrically” from these two opposite, albeit convergent, starting points: the conceptual/rational versus the physical/empiric representations of a territory. In this framework, Grasshopper was used to represent typical standards and parameters of modern urban planning (for example, Floor/Area Ratio, height and distance between buildings, site coverage, etc), and a typological approach was adopted to study and “decode” the relationship between public and private space, between the street, the block and topography, between solids and voids. This methodology permits a cross-comparison of different urban design models and the immediate evaluation of their formal outputs derived from parametric data.

summary	Smart Growth is a fast-growing urban design and planning movement developed by the United States Environmental Protection Agency (EPA). These regulations control urban morphologies such as building form, position, faÃ§ade configurations, building materials, road configurations, which have an explicit association with the microclimate and outdoor comfort. This paper presents an urban modeling and simulation framework that can represent the urban morphology and its impact on microclimate shaped by Smart Growth. First, we created urban models using custom parametric objects and a building component library in BIM. Then we integrated parametric BIM and multiple performance simulations, including wind analysis, solar accessibility, and energy use. For implementation, a case study was carried out using two Smart Growth regulations in the Kansas City metropolitan area. The paper elaborates on the findings from simulation results, challenges in implementation, and limitations of the proposed framework to manage a large number of regulation variables in simulation.

title	Optimizing container housing units for informal settlements - A parametric simulation & visualization workflow for architectural resilience
doi	https://doi.org/10.52842/conf.caadria.2021.1.051
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 51-60
summary	In rapidly growing cities like Dhaka, Bangladesh, sustainable housing in urban wetlands and slums present a challenge to more affordable and livable cities. The Container Housing System (CHS) is among the latest methods of affordable, modular housing quickly gaining acceptance among local stakeholders in Bangladesh. Even though container houses made of heat-conducting materials significantly impact overall energy consumption, there is little research on the overall environmental impact of CHS. Therefore, this study aims to investigate the performance of CHS in the climatic context of the Korail slum in Dhaka. The paper proposes a building envelope optimization and visualization workflow utilizing parametric cluster simulation modeling, multi-objective optimization (MOO) algorithms, and virtual reality (VR) as an immersive visualization technique. First, local housing and courtyard patterns were used to develop hypothetical housing clusters. Next, the CHS design variables were chosen to conduct the MOO analysis to measure Useful Daylight Illuminance and Energy Use Intensity. Finally, the prototype was integrated into a parametric VR environment to enable local stakeholders to walk through the clusters with the goal of generating feedback. This study shows that the proposed method can be implemented by architects and planners in the early design process to help improve the stakeholders understanding of CHS and its impact on the environment. It further elaborates on the implementation results, challenges, limitations of the parametric framework, and future work needed.

summary	The paper aims to analyse the parameters for dimensioning the urban block in the context of the ongoing debate over Rio de Janeiro's new Master Plan (PLC N°44/2021). The analysis focuses on three main points: (1) the definition of the block, (2) the discrepancies found in this regard in the land parcelling system, and (3) the limitations that gated communities impose on the parameterisation of the block. The paper briefly relates the role of the master plan in Brazilian urban policy. Next, it points out the arguments that emerged during the public hearings over the new proposed master plan regarding block sizing. Then, it analyses Rio's urban law framework and the literature regarding the city's road network, cul-de-sac structures and gated communities, supported by the blocks and the streets georeferenced maps available at the Rio's Municipality and the Open Street Maps platform. Finally, it discusses the analysis outcomes with the arguments that emerged during the public hearings regarding block sizing.

title	Towards a Free-form Transformable Structure - A critical review for the attempts of developing reconfigurable structures that can deliver variable free-form geometries
doi	https://doi.org/10.52842/conf.ecaade.2021.2.381
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 381-390
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.

title	Leveraging Urban Configurations for Achieving Wind Comfort in Cities
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 79–90
summary	Given the continuous improvements in digital design and analysis tools, designing in line with the environmental conditions can be much more seamlessly integrated into the conceptual design stage. That leads to faster, informed design decisions and, if incorporated into day-to-day practice, to a sustainable built environment. The presented design method, focusing on enhancing the outdoor wind comfort through architecture, leverages wind analysis tools, such as newly-developed InFraRed, verified by other Grasshopper plug-ins, in the urban design process. As shown in the case study, iterating through various design options and evaluating their impact on the wind flow is faster yet precise, leading towards picking the best-performing design alternative in terms of outdoor wind comfort.

summary	This paper explores the application of an algorithmic-parametric tool that uses urban forestry as a design strategy to reduce the occurrence of flooding. The study was carried out following three main stages: (1) a literature review on the capacity of rainwater retention in tree species with dense canopies; (2) the creation of an algorithmic-parametric tool using C# scripting in Grasshopper to calculate the influence of the trees in reducing the runoff coefficient; and (3) a simulation using Rhinoceros and Grasshopper to verify the performance of such tool. The results show a new method of calculation to estimate the runoff formation in urbanized areas as well as it confirms the contribution of the trees in mitigating flooding.

summary	The Adaptive Solar Façade (ASF) as an integrated dynamic and flexible building facade could be a hopeful design tool to provide residents comfort and energy efficiency by applying relevant integrated parametric design. Based on that, in this study, we investigated a designing process and optimization of ASF concentrating on providing the visual comfort and energy efficiency. We start with an extended summary of previous studies which has been done for developing a dynamic system correspond to origami and butterfly wings. Afterwards, we design 10 movement patterns for façade at the next stage, we simulate the Illuminance uniformity distribution and amount of energy consumption in the interior area. It should be noted that this simulation is done hourly. Therefore, 52 base models were investigated in Hamedan without using intelligent façade. It should be considered that these models are offices and they are investigated in the cold tundra in four days of the year between 6 A.M. to 6 P.M. Afterwards, 520 façade affected proposed models simulated for comparing to the base model. We have done the latter simulation using Colibri plugin while it optimized linearly. All of the datasets have been processed in an algorithm circulation for analyzing the simulations results.

title	Generative Design of Urban Fabrics Using Deep Learning

summary	This paper describes the Urban Structure Synthesizer (USS), a research prototype based on deep learning that generates diagrams of morphologically consistent urban fabrics from context-rich urban datasets. This work is part of a larger research on computational analysis of the relationship between urban context and morphology. USS relies on a data collection method that extracts GIS data and converts it to diagrams with context information (Rhee et al., 2019). The resulting dataset with context-rich diagrams is used to train a Wasserstein GAN (WGAN) model, which learns how to synthesize novel urban fabric diagrams with the morphological and contextual qualities present in the dataset. The model is also trained with a random vector in the input, which is later used to enable parametric control and variation for the urban fabric diagram. Finally, the resulting diagrams are translated to 3D geometric entities using computer vision techniques and geometric modeling. The diagrams generated by USS suggest that a learning-based method can be an alternative to methods that rely on experts to build rule sets or parametric models to grasp the morphological qualities of the urban fabric.

summary	Generative design offers the possibility to heuristically explore data-driven design iterations during the design process. This enables performance-informed feedback and the possibility for exploring viable options with stakeholders earlier in the design process. Since architectural design is a complex, nonlinear process that requires trade-offs and compromises among multiple requirements, many of which are in conflict with each other, a multi-objective solver provides a spectrum of possible solutions without converging on a single optimized individual. This enables a more informed design possibility space that is open to collaborative decision-making. This paper describes the development of a custom multi-objective generative design workflow to visualize families of possible future building typologies with a focus on the impact of site, form, envelope performance, and glazing. Three future design scenarios are generated for three urban U.S. locations projected to grow and where progressive environmental performance stretch codes have been adopted. Drivers such as plausible site, procurement, financing, value chain, and construction typology inform possibilities for built form, envelope technologies, and performance in relation to local codes, environment, and occupant health, are transformed into design inputs through urban, spatial and environmental simulation tools for a "building design generator," or a multi-objective optimizer tool that produces an array of possible building massing and schematic envelope design options. The paper concludes with pointing out some of the gaps in data of current evaluation tools, the need for interoperability across platforms, and this points to multiple trajectories of future research in this area.

summary	This paper presents experimental research about using Augmented Reality (AR) for interactive design processes, exploring a spatial "live" design method taking place in an overlay of real space and digital models. It discusses the processes and outcomes of a seminar undertaken at Graz University of Technology in winter term 2020/2021. Due to the Covid-19 pandemic, the course was taught online, and conceptualized to allow students the biggest possible learning experience during the lockdown. Ensuring accessibility to all participants, the seminar was based on the use of ubiquitous devices. The implementation of newly developed software, such as "Fologram", enabled the students to use AR systems at home with their personal computers and smartphones. The task of the course was to design customized interventions for the students' own domestic spaces, reacting to changing conditions and needs during the lockdown. The employed workflow was driven by an instant connection between 3D-modeling (Rhinoceros3D), parametric design (Grasshopper) and holographic immersion (Fologram).

summary	Shell structure is a kind of structure using a small amount of materials to obtain a large-span multi-functional space. However, lots of formwork and scaffold materials are often wasted in the construction process. This paper focuses on the shell structure construction using robotic 3D printing PLA (an environmental friendly material) technology as the background. The author explores the possibility of 3D printing technology in shell construction from small scale models in different construction method, and gradually optimizes the shell template shape suitable for PLA material in full-scale construction. Finally, the research team chose the bending-active 3D printing type and completed the construction of three full-scale concrete shell molds. Under the guidance of professor Philippe Block, the research team finished the final 3D printing mold with optimized slicing and bending logic and successfully used it as the template mold to carry the tiles which proved the feasibility of this construction method.

summary	Optimisation of free-form building design is more challenging in terms of building information modelling and performance evaluation compared to conventional buildings. The paper provides a Photogrammetry-based BIM Modelling - Machine Learning Modelling - Multi-objective Optimisation framework to improve the solar energy utilisation potential of free-form buildings. Low altitude photogrammetry is used to collect the building and site environmental information. An ANN prediction model is developed using the control point coordinates and simulation data. Through parametric programming, the multi-objective algorithm is coupled with the ANN model to obtain the trade-off optimal building form. The results show that the maximum solar radiation value in winter can increase by 30.60% and the minimum solar radiation in summer can decrease by 13.99%. It is also shown that the integration of ANN modelling and photogrammetry-based BIM modelling into the multi-objective optimisation method can accelerate the optimisation process.

summary	Most approaches developed to teach parametric design principles in architectural education have focused on universal strategies that often result in the fixation of students towards perceiving parametric design as standard blindly followed scripts and procedures, thus defying the purpose of the bottom-up framework of form finding. Material-based computation has been recently introduced in computational design, where parameters and rules related to material properties are integrated into algorithmic thinking. In this paper, we discuss the process and outcomes of a computational design course focused on the interplay between the physical and the digital. Two phases of physical/digital exploration are discussed: (1) physical exploration with different materials and fabrication techniques to arrive at the design logic of a prototype panel module, and (2) deducing and developing an understanding of rules and parameters, based on the interplay of materials, and deriving strategies for pattern propagation of the panel on a façade composition using variation and complexity. The process and outcomes confirmed the initial hypothesis, where the more explicit the material exploration and identification of physical rules and relationships, the more nuanced the parametrically driven process, where students expressed a clear goal oriented generative logic, in addition to utilizing parametric design to inform form finding as a bottom-up approach.

summary	Shellular Funicular Structures (SFSs) are single-layer, two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered as efficient structures applicable to many functions on different scales. Due to their complex geometry, design and fabrication of SFSs are quite challenging, limiting their application in large scales. Furthermore, designing these structures for a predefined boundary condition, control, and manipulation of their geometry are not easy tasks. Moreover, fabricating these geometries is mostly possible using additive manufacturing techniques, requiring a lot of supports in the printing process. Cellular funicular structures (CFSs) as strut-based spatial structures can be easily designed and manipulated in the context of graphic statics. This paper introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS). Furthermore, it explains a fabrication method to build the structure out of a flat sheet of material using the origami/ kirigami technique as an ideal choice because of its accessibility, processibility, low cost, and applicability to large scales. The paper concludes by displaying a structure that is designed and fabricated using this technique.

title	Architecture and Context: A Data-based Approach to Optimize Climate Performance of Built Facades

summary	The present research stems from a critical reflection about the environmental adaptability of existing building envelopes. The main goal is to explore how to balance environmental optimization with contextual constraints, using modularity, flexibility and mass customization as guiding principles. An application study was carried out with the development of a second skin proposal aligned with the use and context of the building under study. For this purpose, simulations that assess environmental conditions were developed within a visual programming tool, not only feeding the design process with essential information, but also providing a flexible creative process. Results show that such simulations allow the designer to interpret these studies more accurately, reducing the iterative guesswork, since in this workflow it is possible to transform these outputs into proposition parameters for new designs or interventions.

summary	The paper describes the findings of the applied research project by Institute Integrative Design (currently ICDP) HGK FHNW and ERNE AG Holzbau to design and manufacture prefabricated wooden façades in the collaborative design manner between architects and industry. As such, it is an attempt to respond to the current interdisciplinary split in the construction, which blocks innovation and promotes standardized inefficient building solutions. Within this project, we apply three innovations in the industrial setup that result in the integrated design-to-production process of individualized, cost-efficient and well-crafted façades. The collaborative design approach is a method in which architect, engineer and manufacturer start exchange on the early stage of the project during the collaborative design workshops. Digital design and fabrication tools enable architects to generate a large scope of façade variations within production feasibility of the manufacturer and engineers to prepare files for robotic production. Novel multi-robot fabrication processes, developed with the industrial partner, allows for complex façade assembly. This paper introduces the concept of digital craftsmanship, manifested in a mixed fabrication system, which intelligently combines automated and manual production to obtain economic feasibility and highest aesthetic quality. Finally, we describe the design and fabrication of the project demonstrator consisting of four intricate façades on a modular office building, inspired by local traditional solutions, which validate the developed methods and highlight the architectural potential of the presented approach.
