title	Towards a Genome for Zero Carbon Retrofit of UK Housing
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 197–206

summary	The United Kingdom has some of the worst insulated housing stock in Northern Europe. This is in part due to the age of housing in the UK, with over 90% being built before 1990 [McCrone 2017, Piddington 2020]. Moreover, 85% of current UK housing will still be in use in 2050 by which stage their Government are targeting Net Carbon Zero [Eyre 2019]. Domestic energy use accounts for around 25% of UK carbon emissions. The UK will need to retrofit 20 million dwellings in order to meet this target. If this delivery were evenly spread, it would equate to over 2,000 retrofit completions each day. Government-funded initiatives are stimulating the market, with upwards of 60,000 social housing retrofits planned for 2023, but it is clear that a system must be developed to enable the design and implementation of housing-stock improvement at a large scale.This paper charts the 20-year development of a digital approach to the design for low-carbon domestic retrofit by architects Constructive Thinking Studio Limited and thence documents the emergence of a collaborative approach to retrofit patterns on a National scale. The author has led the Research and Development stream of this practice, developing a Building Information Modelling methodology and integrated Energy Modelling techniques to optimise design for housing retrofit [Georgiadou 2019, Ben 2020], and then inform a growing palette of details and a database of validated solutions [Moorhouse 2013] that can grow and be used to predict options for future projects [D’Angelo 2022]. The data is augmented by monitoring energy and environmental performance, enabling a growing body of knowledge that can be aligned with existing big data to simulate the benefits of nationwide stock improvement. The paper outlines incremental case studies and collaborative methods pivotal in developing this work The proposed outcome of the work is a Retrofit Genome that is available at a national level.

summary	In this paper, alternative approaches to structure the parametric geometry in relation to information on various performances are described and exemplified. They relate to different levels of knowledge that concern the performances considered in the process and which are available to the designer while the parametric model is being set. A theoretic framework embeds the different approaches, for which the use of parametric modelling is structured in three phases: strategy-definition; model-building; and solution-assessment. The phases and their interrelations are discussed. Finally, four case studies are presented, focusing on the relation between the knowledge available in strategy-definition and the exploration occurring in solution-assessment.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

title	Towards a BIM-Based Energy Rating System

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary	On behalf of the BBR (German Federal Office for Building and Regional Planning) the development of an Industry Foundation Classes (IFC) based inspection tool was accomplished as application on an underlying work-in-progress development framework. By providing a machine-based checking process the tool ModelCheck was rolled out to meet demands emerged during pilot projecting. Thus it is capable of processing automated compliance checks on quality criteria for the authorities, e.g. documentation guidelines of BBR regarding building and real estate documentation or building information modeling (BIM) quality criteria formed for the Humboldt-Forum project – a BIM pilot-project managed by BBR. ModelCheck supports checks on IFC models - formal against schemes and logical inspection with regards to alpha-numeric content by using xml-based configurable rules.

summary	Peripheral devices like smart phones offer an opportunity to lower the barrier to spontaneous collection and sharing of information during distributed collaboration. We have completed development of guidelines and a framework that focuses on peripheral devices in collaboration. In order to explore the design space generated by our principles, we conducted a role-playing experiment about commissioning a building, in which an “on-site” team and a “design” team were expected to find and resolve discrepancies between requirements, design documents, and the actual site. The teams were given Styrofoam panels to act as pretend smart peripherals to invoke play and help probe the design space. We found that “reflection on action” (debriefing and subsequent brainstorming) was fruitful for ideation and theorem building about interaction, but “reflection in action” failed. Yet, reflection in action, particularly with such probes, is important to capture the “mechanics of collaboration”. Therefore, we are considering adapting improvisational theatre to our study of distributed collaboration.

summary	This paper presents preliminary results from an outgoing research about the Scholarship Program on Technological Development and Innovation (PIBITI), in which we focused the potentiality of Augmented Reality (AR) application on documentation of the architectural heritage according to the UNESCO principles. We took as the object of study of the “Quarteirão dos Trapiches”, one of the historic buildings in Laranjeiras, Sergipe, Brazil, and we reconstructed it digitally with Augmented Reality and subsequently generate a QR Code information associated with this building, available on a website. In this context, this work highlight the potential application of architectural heritage documentation in AR, where discourse about the digital processing RA we use, and the association of this digital model with a history of the building. Finally, we present our conclusions on the use of RA in shareholders highlighting the advantages of three-dimensional visualization of architectural heritage, in an interactive, dynamic and low cost of deployment, pondering the importance of encouraging a policy of initiating development activities and technological innovation to digital architectural documentation.

summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 340-349.
summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

summary	There has been a significant need for the new urban design apparatus that carries out performance analyses of the urban models, since the code reform movements focused on the sustainable urban developments. This research explores the use of parametric Building Information Modeling to enable stakeholders to intuitively understand the implications and consequences of urban design codes. We investigate whether key regulations can be captured as algorithms and ontologies in parametric BIM and Object-Oriented Programming. Then we present our prototype of parametric urban models in a BIM platform that explains (1) the extent which urban design code information can be parameterized in BIM and (2) the methods how parametric models can hold code information. The results show that our prototype enables real-time manipulations of code requirements and interactive visualization of code allowances.

summary	In order to understand the applicability of multidisciplinary design optimization (MDO) to the building design process, a MDO framework, titled Evolutionary Energy Performance Feedback for Design (EEPFD), along with the prototype tool, H.D.S. Beagle, were developed to support designers with the incorporation of partially automated performance feedback during the early stages of design. This paper presents 2 experimental case studies, one from the design profession and the other from a design studio, that evaluate the applicability and impact of EEPFD on the early stage design process. Through these two case studies two different interaction and automation approaches for applying EEPFD are explored as part of the framework validation. Observed benefits, challenges and suggestions of EEPFD’s implementation are then presented and discussed.

title	Towards a Computational Spatial Knowledge Acquisition Model in Architectural Space
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 256-266.
summary	Existing research which is related to spatial knowledge acquisition often shows a limited scope because of the complexity in the cognition process. Research in spatial representation such as space syntax presumes that vision drives movement. This assumption is only true under certain conditions and makes these models valid only in specific scenarios. Research in human spatial cognition field suggests that the spatial information perceived by the individual is not equal to the visual appearance of the space, a straightforward way to represent this cognition process quantitatively is lacking. Research in wayfinding usually assumes a certain degree of familiarity of the environment for the individual, which ignores the fact that the individual sequentially perceives information during wayfinding and the familiarity of the environment changes during the wayfinding process. In this paper, a conceptual spatial knowledge acquisition model for architectural space is presented based on the continuous spatial cognition framework. Three types of local architectural cues are concluded to relate common architectural elements to the continuous spatial cognition framework. With all relations in the proposed conceptual model quantitatively described, a computational model can be developed to avoid the aforementioned limitations in spatial representation models, human spatial cognition models and wayfinding models. In this way, our computational model can assist architects evaluate whether their designed space can be well perceived and understood by the users. It can help enhance the way-finding efficiency and boost the operational efficiency of many public buildings.

title	Building Elements Re-usability Optimization - Design Decision Support Using a Case-Base of Building Information Models and Semantic Fingerprints
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 295-305.
summary	The complexity of the requirements on buildings is continuously increasing and thus, often confronting designers with interdisciplinary problems, reaching far beyond the traditional challenges and methods of architecture and engineering. Moreover, designers are often required to take decisions, when most of the information and knowledge is still missing or to be generated. In the context of sustainable building design, the re-usability of building elements and the optimisation for exchangeability is crucial for the achievement of two of the main goals: efficient use of material resources and waste reduction. The scope of this work in progress is describing requirements for case-based decision support in order to optimise building element re-usability, create an analysis of explicit re-usability indicators (e.g. “connection liberation”, “modularity” or “life span collision”) and to identify retrieval strategies. A proposal to support decision making processes by retrieving existing design solutions graph representations as well as the use of building information models are also described.

summary	Integration of analysis into early design phases in support of improved building performance has become increasingly important. It is considered a required response to demands on contemporary building design to meet environmental concerns. The goal is to assist designers in their decision making throughout the design of a building but with growing focus on the earlier phases in design during which design changes consume less effort than similar changes would in later design phases or during construction and occupation.Multi-disciplinary optimization has the potential of providing design teams with information about the potential trade-offs between various goals, some of which may be in conflict with each other. A commonly used class of optimization algorithms is the class of genetic algorithms which mimic the evolutionary process. For effective parallelization of the cascading processes occurring in the application of genetic algorithms in multi-disciplinary optimization we propose a cloud implementation and describe its architecture designed to handle the cascading tasks as efficiently as possible.

summary	The performance of an architectural object is highly difficult to both define and measure in its complexity since it is integrating a constantly increasing amount of information, from concrete measurable characteristics to the subjective perception of individual users. The question arising though is how to predict the performance of a building and influence the design in order to increase it according to a significantly high number of criteria.The presented paper proposes two design tools, both developed and programmed in rhino python for the generation of freeform geometries. The tools are generated for specific tasks, but may be interpreted as exemplary for a way of defining and structuring a design program in order to increase its efficiency. Both tools rely on a computational core that is generally defined and may be fed with as many and different constraints and criteria as considered suitable for the defined task.

title	Knowledge-based methodology for architectural robotics fabrication. Real time impact assessment through a process flow analysis software
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 229-236
summary	The main goal of the project is to generate a framework for a knowledge-based-methodology (KBM) within a parametric software. This is accomplished through a combination of the design software and robot simulation with real-time assessment based on a process-flow-diagram (PFD) structure that compiles the main environmental parameters of the manufacture process. The intention is to create a methodology to directly report the impact of the manufacture of a specific design, from the materials embodied energy to the energy consumption of each step. This framework provides valuable information which may monitor the developer towards alterations to increase the CAD/CAM performance. In the context of this paper, this methodology was applied in the conceptual design and manufacture of a housing structural insulated panel prototype using parametric design software and robotic equipment. The purpose is to generate a quasi-automated design process linked with real-time analysis and assessment of the fabrication process, offering real time environmental and cost analysis of a panelized structure house manufacture logic. The suggested methodology outputs information to compare and optimize the manufacture outline, and supports the screening and assortment of appropriate tool paths or combination of fabrication tools based on environmental/cost data, user-specified requirements and context characteristics.

summary	The most common reason for using Virtual Reality (VR) as a communication medium in urban planning and building design is to provide decision makers with access to a shared virtual space, which can facilitate communication and collaboration in order to make better decisions. However, there is a risk that judgmental biases arise within the virtual space. The displaying of the VR-models and itscontent could be one way of changing the settings for the visual access to the virtual space and could thus influence the outcome of the decision making process. For that reason it is important to have knowledge of how different settings in and around the VR-medium influence the experience of the shared visual space that the VR-medium strives to achieve. In this case the decision-making process, perceptions of space, and the cognition process of decoding of information in the visual space are important. This paper investigates how reference points influence judgments of a volume study of a building and furthermore what visual cues that are used for spatial reasoning about volumes. The results show that the initial visual information has a profound impact on the decision, even when this information lacks in validity.

summary	The idea of ‘city’ has now surpassed its physical concept. The emergence of the Internet and the growing development of information and communication technologies (ICT) have changed the behaviour of our society in the past decade and revolutionised the traditional ways of representing space. The classic 2D (floor plans, sections and elevations) and 3D representations have been gradually replaced by 3D digital models that can reproduce buildings and places in a virtual environment.3D digital models are tools that enable a wide range of applications in urban planning and management, especially in architectural and data documentation where they allow the analysis of theoretical scenarios such as: 1) representation of the past, considering the procedures needed to restore the heritage; 2) visualisation of the present, to enable dissemination and communication of the city as it is; and, 3) simulation of the future, with the model being used to visualise and experiment with architectural objects, even those at a design stage. The main contribution of this work is to present an urban application developed into a GeoBIM tool, ESRI City Engine Software (CE), that integrates GIS (Geographic Information Systems) and BIM (Building Information Modelling) concepts. Finally, to enhance its potential, three spatial analyses were conducted.

summary	The fusion between building assessment and design can lead to better informed design decisions. Performance oriented design is better supported through the use of interoperable file formats for data exchange between BIM and non-BIM tools. At the same time, the parameters that influence the calculation during a performative assessment are no longer a purely engineering problem, since 3D modeling is of primary importance in defining the numerical output. The role of the designer along with the selection of the tools becomes all more relevant in this direction. A framework is presented hereby, which can be used for the selection between different BIM tools for daylight assessment. An insight is also given on the major parameters that can affect the outcome and on the obstacles that were experienced in four case-studies in relation to data exchange and information flow.
