summary	The CorkCrete Arch was an experimental prototype built in the scope of a research project concerning the use of robotic fabrication technologies for non-standard solutions in architecture. It combined 2 materials, cork and GRC into a self-supporting lightweight building system, designed to explore the integration of different robotic fabrication technologies in one constructive solution. This paper is focused in providing a detailed description and analysis of the robotic fabrication process used in the production of the GRC components. The presented solution integrated robotic milling and hot-wire cutting technologies with a stratified mold design strategy that allowed for overcoming the limitations of each and enabled a time and cost efficient production process.

title	An environmental perspective on digital fabrication in architecture and construction
doi	https://doi.org/10.52842/conf.caadria.2016.797
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 797-806
summary	Digital fabrication processes and technologies are becom- ing an essential part of the modern product manufacturing. As the use of 3D printing grows, potential applications into large scale processes are emerging. The combined methods of computational design and robotic fabrication have demonstrated potential to expand architectur- al design. However, factors such as material use, energy demands, du- rability, GHG emissions and waste production must be recognized as the priorities over the entire life of any architectural project. Given the recent developments at architecture scale, this study aims to investi- gate the environmental consequences and opportunities of digital fab- rication in construction. This paper presents two case studies of classic building elements digitally fabricated. In each case study, the projects were assessed according to the Life Cycle Assessment (LCA) frame- work and compared with conventional construction with similar func- tion. The analysis highlighted the importance of material-efficient de- sign to achieve high environmental benefits in digitally fabricated architecture. The knowledge established in this research should be di- rected to the development of guidelines that help designers to make more sustainable choices in the implementation of digital fabrication in architecture and construction.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary	In Brazil, the application of wood in contemporary constructions is concentrated in the south and southeast. However, the entire country has area for cultivation and forest management, which is favorable for expansion in such applications. Wood is capable of absorbing CO2 and consumes little energy in production and manufacturing. During the COVID-19 pandemic, the deficiencies of the building typologies became evident. This research aims to analyze digitally executed prefabricated houses such as Instant House (1), Digitally Fabricated House (2) by Sass, and WikiHouse (3) by Parvin; under the categories of Cardoso (2016): modulation, reversibility, and flexibility. The deductive method was used to investigate assumptions among the three case studies; and grounded in scientific literature to analyze and collect data. In general, the solutions studied enabled customizable systems allied to wood panels, modules, and fittings as generators of architectural form.

summary	Brick has been used in construction since ancient times and has been respected among other tectonic materials through out the history. Novel technologies recently have opened new horizons in using brick in architectural design. This paper investigates innovative implementation of bricks in kinetic architecture. Kinetic structures usually employ complex and high-cost mechanisms to come into force and their movements might be limited to some conditions. By the use of magnet in digital design, this research examines new methods for performing simple and affordable kinetic structures so as to create interactive relations between architecture and human being. Magnetic energy is applied in two ways to move a roof made of brick which is considered a heavy and masonry material. Consequently, it represents the hidden potentials of magnet as a renewable source of energy.

title	Development of the Integrated Management Environment of BIM Property Information for BIM-based Sustainable Design
doi	https://doi.org/10.52842/conf.caadria.2016.487
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 487-496
summary	With the growing responsibility for the environmental load of building, the demand for sustainable building is increasing. Sus- tainable design requires an enormous amount of information, and most of this information can be captured by Building Information Modelling (BIM). In this context, the management of information in a BIM object as a container for exchanging information is necessary for analyzing a building’s sustainability. However, there are problems in generating a reliable sustainability simulation model from BIM, such as the inefficiency of required information and low accessibility to a proper BIM object. In order to provide a new approach for generating a reliable sustainability simulation model in a BIM-based design pro- cess, this study suggests the integrated management environment of the property information of a BIM object.

summary	Building design entails an intuitive and informative exploration of an architect involving iterative refinement of design ideas till client objectives, and priorities are satisfied. Similarly, service cores in a building are designed through the exploration of multifarious design options each with different performative metrics regarding accessibility, efficiency, cost, feasibility, etc. As the current process is labor-intensive, manual & dependent on the expertise of the architect, the search space leading to the selection of an optimal design alternative is very limited. This paper describes Service Core Generator (SCG) library in Autodesk Dynamo enabling automated generation of service core models for varied building shell geometry types (limited to orthogonal profiles). The tool described encodes explicit and implicit domain knowledge into the system facilitating service core models for buildings across varied scale with use type's including offices, hotels or residential buildings.

summary	It is important to discuss and compare the rationale behind the success of the additive manufacturing technology in particular industries and at a particular scale versus full-scale building construction. The comparison should include structural qualities of the possible used materials, the cost effectiveness of the process, the time factor and its value in the construction process, the mass customization potential of the technology and its effect on building forms. The current state of technology in architecture, despite huge potential, has not produced new architectural forms.

summary	The objective of this paper is to clarify how value creation can be a part of architectural design and end-products when using the new emerging technology of additive manufacturing. Different kinds of values that have emerged from the research material have been analysed and summarised using selected case studies of recent building-scale projects. In applying this technique to architecture, the result can be visually and functionally novel, smarter and more sustainable buildings or products. A new individually manufactured or customised architecture can be created to serve different cultural and well-being needs cost effectively and without any waste. This new production method can lead to unique joint structures with the use of traditionally produced new or old building parts to enhance architecture, prevent climate change or aid environmental issues. However, most research projects and applications done by commercial companies are at the early stages.

summary	Building Performance simulation is escalating towards design optimization worldwide utilizing computational and advanced tools. Egypt has its plan and agenda to adopt new technologies to mitigate energy consumption through various sectors. Energy consumption includes electricity, crude oil, it encompasses renewable and non-renewable energy consumption. Egypt Electricity (EE) consumption by sector percentages is residential (47%), industrial (25%) and commercial (12%), with the remainder used by government, agriculture, public lighting and public utilities (4%). Electricity building consumption has many divisions includes HVAC systems, lighting, Computers and Electronics and others. Lighting share of electricity consumption can vary from 11 to 15 percent in mixed buildings as in our case study which definitely less that the amount used for HVAC loads. This research aims at utilizing shape morphogenesis on facades using geometric shape grammar to enhance daylighting while blocking longwave radiations causing heat stress. Mixed-use building operates in daytime more than night which emphasizes the objective of this study. Results evaluation is referenced to LEED v4.1 and ASHRAE 90.1-2016 window-to-wall ratio calibration and massive wall description. Geometric morphogenesis relies on three main parameters; Pattern (Geometry Shape Grammar: R1, R2, and R3), a reference surface to map from, and a target surface to map to which is the south-western façade of the case study. Enhancing Geo-morph rule is to guarantee flexibility due to the rotation of sun path annually with different azimuth and altitude angles and follow LEED V4.1 enhancements of opaque wall percent for building envelope.

summary	This study aims to better ascertain the influence that urbanistic parameters exert on the production of solar photovoltaic energy regarding different contexts in the city. Modifications implemented between the years of 2012 and 2016, especially on variables such as Maximum Lot Coverage, Floor Area Ratio, and Setbacks, have been evaluated through virtual models that cover areas in three different city districts. Amongst other implications, an increase in the area occupied by the buildings, as well as a decrease in the distance between them, occurred, causing more mutual shading and the loss of the photovoltaic potential associated with the building envelope.

summary	The research builds on the relationship between matter and energy and the idea of boundaries as sentient interfaces capable of affecting our bodily experience and perception of space due to their inherent physical attributes. Two key issues addressed are firstly, the revisiting of the architectural boundary as a thermodynamic zone and secondly, the identification of material behaviour in relation to energy stimuli. It is argued that the transient behaviour of materials can offer an instrumental reconsideration on how architecture establishes spatial articulation through boundaries and this is demonstrated through a design-led project.

summary	Lighting analysis tools have proven their ability in helping designers provide functional lighting, increase comfort levels and reduce energy consumption in buildings. Consequently, the number of lighting analysis software is increasing and all are competing to provide credible and rigorous analysis. The rapid adoption of parametric design in architecture, however, has resulted in complex forms that make the evaluation of the accuracy of digital analysis more challenging. This study aims to evaluate and compare the performance of daylighting analysis in two industry standard software (Autodesk Revit and 3ds Max) when analysing the daylighting of complex parametric façade patterns. The study has shown that, generally, both Revit and 3ds Max underestimate illuminance values when compared to physical scaled models. 3ds Max was found to outperform Revit when simulating complex parametric patterns, while Revit was found to outperform 3ds Max when simulating simple fenestration geometries. As a general conclusion, the rapid progress of parametric modelling, integrated with fabrication technologies, has made daylighting analysis of complex geometries more challenging. There is a need for more sophisticated algorithms that can handle the increased level of complexity as well as further verification studies to evaluate the accuracy claims made by software vendors.

title	Integrating CFD and VR for indoor thermal environment design feedback
doi	https://doi.org/10.52842/conf.caadria.2016.663
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 663-672
summary	In the context of environmental consideration and im- provement of living standards, design of high performance buildings that are both comfortable and energy saving is important. Simulation tools (such as CFD) enables analysing and visualizing environmental factors (such as temperature and airflow) based on the design proper- ties and can be used to improve the building design for better perfor- mance. However, these tools have limitations in providing interactivi- ty with users for creating multiple CFD visualization results to be used for analysing design options. This research presents an integrated de- sign tool which consists of CFD and VR technologies. The proposed system visualizes CFD results in a VR environment together with ar- chitectural design. Additionally, it enables configuring CFD parame- ters within the VR environment and allows repeatedly executing simu- lation and visualizing updated results. The proposed system enables visualizing information in relationship with the actual architectural design, space configuration and thermal environment, and provides ef- ficient design feedbacks.

title	Parametric Islamic Geometric Pattern for Efficient Daylight and Energy Performance - Façade retrofit of educational space in hot arid climate
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 227-236
summary	The purpose of this paper is to reach an optimal Islamic geometric pattern (IGP) shading screen design in terms of daylight and energy performance in an existing educational design studio (EDS) using generative design and simulation techniques. The study was carried out in a hot arid climate, in a typical EDS in 6th October University, located in Cairo, Egypt, and the study focused on the north-east oriented façade. Grasshopper for Rhino was utilized to generate the IGP parametric variations. Diva-For-Rhino which performs daylight analysis using Radiance / DAYSIM, and Design Builder which performs thermal load simulations using EnergyPlus were utilized in simulation. The results of the study achieved the required daylight levels with significant reduction of energy consumption levels of cooling load. This shows the affordance of the parametric IGP shading screens in façade treatment for achieving both efficient daylight and energy performance in educational design studio in hot arid climates.

summary	This paper deals with geometric update strategies of cobogós, aiming to expand its energy efficiency based on material computation, a design approach that seeks to achieve greater architectural performance through the investigation of material properties, comprising four aspects that structure the paper: materiality, material structure, material performance and materialisation. Analysis in ceramic, the most common material in the manufacturing of cobogós, showed voronoi microstructure geometry in the material. Incorporating this logic to the development of a new geometry of cobogó results a slight increase of its thermal performance comparing with commercial cobogós.

summary	This paper proposes a novel concept and practice to engage the BIM model as a control system of building energy performance service. This issue can be divided into two sub-issues including the development of more eco-friendly fac?ade which can interact with its local environment, and the related active control system which can process the environmental parameters for eco-friendly actions. This research designs the Parametric Adaptive Skin System (PASS) to en- gage the adaption of natural sunlight use for higher building perfor- mance. PASS consists of kinetic fac?ade components dominated by the BIM-based parametric engine called Dynamo. The PASS prototype demonstrates that the workflows is successful in using a real light sen- sor plus simulated solar terms to drive the interaction of virtual Revit model and physical PASS model.
