title	SECTIONMATRIX - Mapping Urban Form through Urban Sections

summary	Most of the traditional studies on urban morphology are based on aerial views. However, the 2D plane model fails to describe the height information of buildings and the relation of buildings and the urban external space. An urban section is another map of an urban area. Through a series of continuous vertical urban slices, the city texture can be transformed into planar linear information containing height and width information. This paper proposes several indicators to describe a series of urban section slices and uses a three-dimensional coordinate mapping method Sectionmatrix to quantify and analyze the relation between the physical geometrical indicators and urban form from the section perspective. Through the case analysis of multiple residential blocks in Nanjing, China, the results showed that Sectionmatrix is convenient and efficient. Sectionmatrix relates the geometrical properties to the spatial characteristics of urban areas and provides a new way to classify, map and define building typologies. This new classification method reveals the tortuosity and complexity of residential blocks. By bridging the gap between quantity and form, the research also suggests other possible applications of Sectionmatrix as a control instrument and test framework for entire cities planning and design.

summary	This project develops a template design and an adaptive fabrication process for sustainable Compressed Earth Block (CEB) dwellings for low-income countries. Most existing projects (Wilton et al. 2019; WASP 2021) on sustainable dwellings involve high-tech equipment or skilled workers on-site. This project integrates digital technologies into the design and fabrication processes to reduce these requirements and make the design compatible with conventional construction methods that are actively adopted in low-income countries using minimum infrastructure, skilled labor, and investment.

title	The Synergy of building massing and facade - An Evo-Devo approach for performance-based design optimization combining facade design with building massing
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. 451-460

summary	One of the problems lies in performance-based architectural design optimization is the separation of building massing design and facade design. The separation of design processes significantly weakens the synergizing of building massing and facades for more progressive performance improvement. In order to overcome this weakness, this paper presents a performance-based design optimization workflow combining facade with building massing design using an Evo-Devo approach. This workflow enables architects to make a rapid design exploration of different faÃ§ade design schemes incorporating building massing design optimization. For demonstration, a case study is presented to show how this approach can facilitate early-stage architectural design exploration, and how the combination of the two factors can outperform the results produced by separated design processes.

summary	The paper based on microclimate environment of the site takes the optimized design of rural building form to help the rural revitalization and sustainable development. The reconstructedÂ house project inÂ Baihua Village of Tangchi Town in Anhui Province is taken as the research case to discuss the form optimization strategies. Based on the principle of passive priority and active optimization, the building in Baihua Village is analyzed byÂ field investigation and numerical simulation. First, the outdoor environment is interpreted by using Weather Tool software to offer a building form proposal. Then, with the drawing software CAD, ecological building simulation software Ecotect, and green building analysis software PKPM, the optimization strategy analysis of healthy building form was carried out to verify the optimal solution of building form based on Chinas national standards. Finally, this paper summarized and improved the rural building optimization design system for a healthy microclimate environment. The results of this paper are hoped to use for the contemporary rural architectural form design.

title	EvoMass + GH_Wind - An agile wind-driven building massing design optimization framework
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 477-486

summary	The complex interactive relationship between wind flow and building design poses a great challenge in architectural design. Recent research has been conducted to combine Computational Fluid Dynamics (CFD) and computational design optimization to solve the problem. However, due to the time-consuming simulation process and the assertion-oriented computational optimization application, such CFD-based design optimization frameworks are not easy to integrate with architects' early-stage design exploration. To address these issues, this paper proposes an agile wind-driven building massing design optimization framework incorporating EvoMass and GH_Wind in the Rhino-Grasshopper environment. EvoMass is an integrated evolutionary building massing design tool, and GH_Wind is a simulation tool embedded with a Fast Fluid Dynamics (FFD) solver. Combining these two tools allows for fast wind-driven design optimization, thereby enabling architects to apply it to early-stage design exploration. To demonstrate its efficacy, a case study is presented to illustrate how the proposed design optimization framework can provide architects with useful design information and, thereby, facilitate more performance-informed design for early-stage architectural design.

title	Optimization of Daylight and Thermal Performance of Building Façade: A Case Study of Office Buildings in Nanjing
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_16
summary	In China’s hot summer and cold winter areas, the façade design of buildings needs to respond to a variety of performance objectives. This study focuses on the optimization of daylight and solar radiation of building façade of office buildings in Nanjing and proposes a simple and efficient method. The method mainly includes a random sampling of design models, simplified operation of daylight performance criteria and selection of optimal solution. The results show that the building façade can improve the indoor lighting uniformity and reduce the indoor illumination level compared with the unshaded reference building. Besides, the amount of solar radiation received by office buildings in summer and winter becomes more balanced with the building façade. The optimization design method of building façade proposed in this study can be of guiding significance for office buildings in Nanjing.

title	A Generative Approach to Social Ecologies in Project [Symbios]City
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_2
summary	The following paper talks about the studio project [Symbios]City, which is developed as a design research project in 2020–2021 Schumacher’ studio on social ecology of the graduate program in Architectural Association’s design research lab. The project aims to create an assemblage of social ecologies through a rich but cohesive multi-authored urban district. The primary ambition is to generate an urban area with a characterful, varied identity, that achieves a balanced order between unity and difference avoiding both the sterile and disorienting monotony of centrally planned modernist cities and the (equally disorienting) visual chaos of an agglomeration of utterly unrelated interventions as we find now frequently. Through a thorough research process, our project evolves mainly out of three principles that are taken into consideration for the development of our project: topological optimization, phenomenology, and ecology. By “ecology”, we understand it as a living network of information exchange. Therefore, every strategy we employ is not merely about reacting to the weather conditions, but instead it is an inquiry into the various ways we can exploit the latter, a translation of the weather conditions into spatial and programmatic properties. [Symbios]City therefore aims at developing a multi-authored urban area with a rich identity that achieves a balance between the various elements. [Symbios]City began formally from topological optimization, developed based on studies on ecology, and concluded the design following our phenomenological explorations, aiming at a complex design project that unifies the perception of all scales of design: from the platform to the skyscrapers.

summary	On-site construction is one of the main research directions of robot construction. Due to the complex and everchanging construction environment on the site, traditional offline programming and simple conditional programming cannot meet the needs of robot on-site construction at all. Realtime adjustment of the robot's operating program for the real-time situation in the field is the appropriate solution. Therefore, the real-time communication and control of robots has become a key issue for robot on-site construction. This article discusses in turn the way of robot offline program control through EthernetKRL and grasshopper. A remote real-time communication and control method for an on-site construction robot is studied, and the application of the method in the on-site construction process of an actual robot is introduced with the Wuzhen coffee kiosk project as an example. Based on the above methods, remote real-time monitoring of the construction robot on site can be realized, which provides a reference for the actual engineering application of the construction robot on site.

title	Designing a Living Material Through Bio-Digital-Fabrication - Guiding the growth of fungi through a robotic system
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 77-84

summary	Designing with living materials require designers to look for new methods of fabrication since living cells exhibit their own agency, and are able to sense and respond to environmental stimuli. Therefore, there is an urgent demand to design a framework for fabricating living materials. This paper investigates the digital-fabrication of fungi as a new way of designing and crafting living materials without genetic manipulation. In this research, fungi act as a bio-material probe to generate and test new design strategies that enable a dialogue between digital and biological systems. Conceptual experiments, that use fungi to investigate the proposed bio-digital-fabrication scenarios, are central in this study. The research attempts to generate new information for the design process of an organism in the field of architecture. The project will expand on the latest thinking on the bio-material fabrication by allowing the living material to be engaged in the fabrication process.

title	Command2Vec: Feature Learning of 3D Modeling Behavior Sequence—A Case Study on “Spiral-stair”
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_5
summary	In this study, we applied machine learning to mine the event logs generated in modeling process for behavior sequence clustering. The motivation for the study is to develop cognitively intelligent 3D tools through process mining which has been a hot area in recent years. In this study, we develop a novel classification method Command2Vec to perceive, learn and classify different design behavior during 3D-modeling aided design process. The method is applied in a case study of 112 participate students on a ‘Spiral-stair’ modeling task. By extracting the event logs generated in each participate student’s modeling process into a new data structures: ‘command graph’, we classified participants’ behavior sequences from final 99 valid event logs into certain groups using our novel Command2Vec. To verify the effectiveness of our classification, we invited five experts with extensive modeling experience to grade the classification results. The final grading shows that our algorithm performs well in certain grouping of classification with significant features.

title	Topology Reconstruction of a Discontinuous B-rep Geometry by using Form Finding Method
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. 371-380
doi	https://doi.org/10.52842/conf.ecaade.2021.2.371
summary	In the field of industrial manufacturing and building design procedure, B-Rep (Boundary Representation) model is often used to design and fabricate building components or molds, but in the finite element analysis(FEA) procedure, engineers often need to use the F-Rep (Functional Representation) model files. So, converting two file formats back and forth from one to another is a very important topic in architectural design and manufacturing process. However, there are still some limitations to carry out the conversation process efficiently on discontinuous B-rep geometries with existing software and plug-ins. In this paper, authors introduce an efficient retopology method with kangaroo physics plug-in based on Rhino platform to convert a B-Rep file into a F-Rep file (a continuous uniform mesh infinitely approached to the original geometry with a controllable face numbers) within limited steps. Thus, designers and engineers can do creative parametric design or finite element analysis continuously without surface boundary limitation. Furthermore, the mesh converted by the method introduced in the paper has a better regularity on each single face and better homogeneity of all faces than the built-in "QuadRemesh" function in Rhino-7.

title	3D Concrete Printing with Variable Width Filament

summary	Traditional mold-based concrete construction methods are inefficient, poor quality, and labor-intensive. Concrete 3D printing technology is expected to replace traditional methods as an emerging intelligent construction method due to its flexible, automatic, fast, and mold-free features. Concrete 3D printing is a method by extruding and selectively laminating construction materials onto a specific path, relying on fine-grained control of the printing material and the printing device. However, the maximum printing resolution is limited by the width of the toolpath. Filament width and printing resolution are two main factors that need to balance. In this paper, a variable width printing method is proposed using the active nozzle speed control method. The width of the print path can be adjusted according to the model details. A width control algorithm is proposed. The general workflow of variable width printing, including model preparation, toolpath planning, robotic fabrication, is also introduced, and a concrete bench is printed for experimental validation. The result shows great application potential for surface decoration and structural reinforcement. The efficiency, feasibility, and problems encountered in printing are analyzed and summarized.

title	PolyTile 2.0: Programmable microtextured ceramic architectural tiles embedded with environmentally responsive biofunctionality
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 65–85
summary	PolyTile 2.0 interrogates the potential of programmable biofunctionalities in our constructed architectural environmentsthrough the development of advanced ceramic bio-tiles. These tiles utilize novel patterning techniques and hydrogelbiomaterials to tune surface conditions at the micro- and macroscale. This trans-disciplinary work builds upon recentadvancements in the fields of three-dimensional printing, digital ceramics, materials science, bioengineering, chemicalbiology, and architecture. PolyTile 2.0 enables designers and architects to implement biofunctionality and microscalepatterning fittingly and with the ability to continuously adjust design iterations across scales. The refinement utilizesglazing strategies as a directable fluidic device and biocompatible hydrogels as a sensing platform to further developmentsin responsive built environments. This article outlines methods for the production of bulk-scale hydrogel materials,stereolithography-based three-dimensional printed ceramic tiles, and scalable glazing techniques, which bring building-scale application of this technology to the foreground.

summary	Graphic statics vividly shows the topological relationship between the "form" represented by the structure itself and the "force" generated by its action through graphic method, which has become an important tool for architects to carry out structural innovative design in the past century. In the 21st century, with the development of computer technology, graphic statics has developed from the dual relationship between 2D thrust network and closed force polygon to the dual relationship between 3D thrust network and space closed force polyhedron. In this paper, the design method of graphic statics based on 3D graphic statics is applied to a stainless chair and an ice pavilion design. Researchers used different digital fabrication methods to manufacture the chair and the pavilion according to its material attribute.

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.
