title	Visualizing Dynamic and Highly Interactive Lighting
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 119–128
summary	As a defining factor in shaping people’s experience in architectural spaces, lighting is realistically visualized via a plethora of rendering options in CAD and BIM solutions. However, their outputs are usually static or limited to basic changes. Thus, they may not satisfactorily visualize many dynamic and interactive lighting scenarios, such as energy-saving smart windows and lights, engaging street illumination, and entertainment setups. With the increasing automation of human-building interaction (HBI), visualizing such interactions empowers researchers and students who are interested in experimenting with customized lighting setups. Moving in this direction, this paper presents the lighting features of Tames, an open-source Unity toolkit developed by the author that visualizes dynamic and interactive elements in virtual environments without a need for programming. With Tames, the designers can navigate and interact with the design from the perspective of an occupant with the lighting and other elements in real-time manually or automatically. The workflow and capabilities of Tames are demonstrated by its application in the context of concert hall project designed by a student. This author argues that the availability and user-friendliness of this tool will contribute to architectural pedagogy and research. It allows students and researchers to visualize a wider variety of interactive designs and cases easier and, as an enabling tool, it may encourage them to explore and experiment with dynamic and interactive lighting.

title	Mycelium in Architectural Education
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 169–174
summary	With supply chain issues and rising price of construction materials, mycelium can potentially provide reliable, eco-friendly and sustainable alternatives to traditional construction materials as substrates used for growing mycelium can contain almost any recycled cellulose: sawdust, used coffee grounds or paper. Characteristics of the final product are determined by substrate, mushroom species, the time of growth and further treatment of mycelium (e.g. high pressure forming). In this paper we describe semestral work of both students and tutors of an Experimental studio, focused on additive manufacturing together with rather novel sustainable materials. Students’ semestral task was to find use cases for mycelium as a building element. As a part of the assessment they were tasked to come up with use cases, designs, manufacturing methods and finally build a mock-up model in 1:5 scale. Students intuitively started with the combination of digital modelling plus digital fabrication. In the end they finished with manufacturing the physical model traditionally, where they had to react to the change of the visual outcome of the model. Firstly, we present the students’ solution for the mycelium material used in their model, next, we describe our observation of the whole process of letting students go through “learning by doing” research, Finally, we present lessons learned in this experiment.

title	A Novel Approach of Structural Modeling, Analysis and Optimization of Bearing Parts in Free-Formed Arc-Like Geometry Reconstructed from 4D Sketches
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 69–78
summary	Sketching is often used as the main approach in design of free-formed structures in very early stages of planning. Chosen materials for bearing and non-bearing parts and results of structural analysis can decisively affect the shape and form of planned geometry. The structural modelling, following finite element (FE) analysis and structural design can be very time-consuming due to still weakly regulated building information modelling (BIM) data exchange of free-formed structures. This paper describes a novel approach of structural modelling, analysis, and multi-objective optimization (MOO) of bearing elements of free-formed geometry sketched within a developed 4D semantic, mixed reality application MRSketch. The shapes of individual elements are computed from the recovered curve network and comprising boundary curves, aiming for smooth transitions and less deviation to the sketched strokes. The focus of this paper lays on the test case in which a free-form voluminous arc-like structure (similar to BUGA pavilion) has been thoroughly sketched in MRSketch. The computed geometry of the above-mentioned form is used for the structural analysis and MOO, whereby 3 different material and structure types are studied: monolithic concrete shell, plywood timber panels, and steel framework. The MOO process takes place with the goal of minimizing used material masses and de-flection of the structure. The ultimate and serviceability limit state´s (ULS and SLS) criteria acc. to Eurocodes represent MOO-constraints. Lastly, a large-scale estimate of the CO2 balance of the 3 above-mentioned construction´s variants is compiled and compared.

summary	Nowadays, sustainability is in the agenda of most of the countries and international organizations. Among the 17 Sustainable Development Goals of the United Nations, Goal 11 Sustainable Cities and Communities sets specific targets for cities to adopt solutions for inclusion, safety, resource efficiency, resilience, mitigation and adaptation to climate change. Furthermore, it is increasingly evident among designers and researchers that design methods and solutions doing less harm or with a neutral effect on the environment are not sufficient anymore. A holistic approach is necessary in designing for a positive effect on climate change, resource depletion, human health and natural systems as a whole to develop sustainable architecture design solutions as well as regenerative and resilient cities. Computational design allows us to develop workflows considering the built environment, humans and natural systems as a whole, by integrating simulations such as climatic, environmental, materiality, energy, behavior and use, and performances such as energy balance, usability, structural, fabrication, comfort, health, and costs, at multiple scales. The symposium and workshops reflected and experimented new concepts, methods, and solutions to create a positive impact on the urban environment and the city, but also on humans and the natural environment, taking advantage of the potential of computational design to integrate performance-driven and simulation-based workflows. Furthermore, the objective of the symposium was to explore the potential of computational design in proposing a new architectural paradigm through performance and simulation. Particular emphasis has been given to research showing innovative holistic, multi-disciplinary, multi-domain, multi-scale, and multi- objective approaches to guide and support the scientific and design community at large to design sustainable cities and communities.

title	Methodology for Improving Wind Comfort in a Cold Region Through Modular Urban Elements
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 5–14
summary	This paper discusses wind comfort improvement strategies as a crucial microclimatic issue in urban planning. The investigation used pergolas as a wind catcher/breaker element to improve wind comfort at the pedestrian level in Tallinn, Estonia, during extraordinarily windy and cold times of the year. We analyzed the impact of buildings and other surrounding elements on wind flow to design pergolas as windbreakers. Case studies include three urban areas. The wind flow has been simulated using Computational Fluid Dynamics (CFD) on the micro-climate scale using ENVI-met. The CFD analysis allowed us to understand urban wind flow phenomena and apply solutions to mitigate distress and guarantee more comfort. According to the CFD results, the urban zones show a high rate of wind speed under different meteorological conditions and, consequently, extreme wind discomfort. The analysis results of 48 scenarios based on different meteorological cases were used to select the most performative retrofit solution and provided insight into windbreak pergolas’ size, layout, and location to provide comfort. Thus, improved geometrical models of case studies were simulated and analyzed. The results showed that the designed pergolas offer high wind comfort at the pedestrian level, especially in open urban areas, and could assist municipalities, city planners, and urban designers in creating more comfortable and sustainable urban environments.

title	COVID-19 and the City: An Analysis of the Correlation between Urban and Social Factors and COVID-19 in Fortaleza, Brazil
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 45–52
summary	The COVID-19 pandemic has been the biggest sanitary crisis humanity has ever faced, the virus has contaminated 662.717.929 people worldwide and killed 6.701.270 people. However, these numbers were not distributed equally at international, national or urban scale. In Fortaleza, Brazil, city studied in this paper, data from 2021 and 2022 epidemiologic reports suggest a contamination pattern that starts in neighborhoods with higher Human Development Index (HDI) and then goes to lower HDI neighborhoods, however, throughout all of this cycle, low HDI neighborhoods tend to have a higher lethality rate. These facts raised the hypothesis that those neighborhoods have specific urban and social factors that affect the capacity to respond and prevent COVID-19. The main objective of this paper is to identify the correlation of some urban and social factors with COVID-19 data. To achieve that, the authors selected seven variables (access to water rate, literacy rate, waste collection rate, population density, access to electric energy rate, sanitation rate and average monthly income) to correlate with four COVID- 19 indicators (total number of cases, total number of deaths, contamination rate and lethality rate). For this, it was chosen to apply Spearman’s correlation coefficient and for the calculation the statistical software Jamovi was used. The results show that the literacy rate, the access to electric energy rate and average monthly income have a positive correlation with the contamination rate, however these same variables have a negative correlation with the lethality rate.

title	Thermal Engagement: A method and model for analysing and organising thermal-active materials close to the human body
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 89–97
summary	This study examines the performance and application of thermal-active materials by use of phase-change-composite structures close to the human body. The aim is to understand and model the thermal impact on a person in an office environment through 3 design test cases. In this process a design method is proposed to position PCM-wood based composites. Investigations are based on material studies by composite development and thermographic analysis, computational studies by generative design and thermal sensation modelling, and comparative studies from computational design and analysis processes by graphical mapping of results. The study finds that the PCM-wood composites have an impact on the thermal sensation within the cases studied, but only by the application of a large thermal-active surface close to the human.

source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 25–34
summary	This paper presents a novel workflow for managing urban data and visualizing them with the use of a mixed reality interface for studying historic urban cores in participatory design scenarios, using as a case study the Strovolos historic core in Nicosia, Cyprus. The application provides a data-enabled interactive medium to measure key aspects of urban accessibility with real time data feedback, to test design hypothesis and record user input. The goal is the creation of a user driven urban database and facilitate decision making of urban scenarios in consideration of walkable cities.

title	Between System and Improvisation: Aesthetic performance in Donald Judd’s 100 untitled works in mill aluminum
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 79–88
summary	In this paper, we intend to analyze Donald Judd’s “100 untiled works in mill aluminum” to see whether they belong to a system, and, if so, what that system is and what delimits it. Our hypothesis is that there is a system driven by shape data, but the system is tempered by improvisational moments at multiple junctures in the project. We are interested in deciphering the systematic, but also the moments of artistic improvisation. To that end, we will look at the roots of data-driven design in the “serial” artworks of the early 1960’s documented in two Artforum essays by Bochner and Coplans, both citing Donald Judd. This period of artistic production is critical in the context of the development of shape grammars in computation which followed in the early 70’s with Stiny and Gips’s Shape Grammar essay. In 1983, Knight used shape grammar to describe the transformation of design languages. In the same period, Donald Judd, without the aid of computation or knowledge of shape grammar, developed a grammar towards the design of “100 untiled works in mill aluminum.” We intend to explore Judd’s 100 works as an example of the utilization of information and its analysis towards design and innovation, and to highlight the role of artistic improvisation in a systemic design process.

title	Physicalizing Digital Design Methodology: Material-linked digital making
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 149–158
summary	Architectural design process, heir to craftsmanship traditions, formulates making as its vehicle of analysis. This curious pedigree directs high-level thought process through the restraint of material limitations; a methodology based in respect for materials whose properties and tendencies are capable of driving outcome. In this tradition of making, design as an intellectual act is dependent on engaging active, spatiomaterial media. Additionally, contemporary literature suggests physical materiality as an interface is uniquely suited to human intelligence, at once corporeal and intellectual. Therefore, if digital is understood as an extension of our intellectual thought process, its evolution should intertwine with the physical. This paper reports on research examining the role of physicality as a component of digital design method. The research constructs hybrid models and physicalizations, physical makings parametrically linked to inform digital design; thereby testing the integration of physical and digital as a material-based digital making methodology. The proposed next digital turn is a return to materiality as conduit transporting the full range of human intelligence (sensorial, intuitive, and intellectual) within digital making. Key to this methodology is designing with live, spatiomaterial media capable of reacting and providing feedback during making. The supposition contained turning towards physical-digital integrated methodology is that the wicked problems we face are best served by a design methodology accessing the full arsenal of our intelligence with media that is connected to the same multiplexity of context it seeks to remedy.

summary	The practice panel of the RIS 2023 aimed to illuminate how the knowledge generated by a community such as eCAADe is applied in the realms of architecture, planning, and policy in the Estonian context. Touching upon different aspects of practice, the presentations highlighted three main directions towards regenerative design: facilitating participatory processes, augmenting creativity by incorporating performance simulations into the early design stages and harnessing digital technologies to manage complex problems. Besides its value as a case study of the Estonian context, the practice panel can serve as an inspiration for a more complex – and messy – understanding of performance.

title	An Experimental Investigation of Latent Heat Storage for Solar cooling Systems using Paraffin Wax
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 55–60
summary	Latent heat thermal energy storage units employ phase change materials to store and release heat at a nearly constant temperature, ensure high heat transfer efficiency, as well as high charge and discharge capacity. Phase change materials (PCMs), allow a more compact, efficient, and therefore economical system to operate. Thermal Energy Storage (TES) systems are of growing importance within the energy awareness, because of TES can reduce the levelized cost of electricity of solar cooling systems. This paper proposes a comprehensive methodology where simulations were performed to demonstrate the phase change process of paraffin wax and to improve the effect of PCM modules on the heat transfer process. PCM modules were tested in the laboratory, then their impact on thermal energy storage were determinate. The rise of COP of solar absorption cooling system was calculated.

title	BIM and Teaching in Architecture: Current thinking and approaches
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 105–115
summary	Increasing use of BIM has represented a continuing shift in traditional assumptions on how we navigate the design process. BIM is affording the student the ability to gain a greater understanding of their design ideas via the exploration of scale, spatial organisation and structure, amongst many other design layers, in increasing levels of detail, at the same point in the design process. Architectural education is at a delayed tipping point where architectural students are increasingly looking towards BIM to streamline their design process drawn by the production of realistic visualisation, but with a lack of knowledge and skill in its application. With a lack of guidance and understanding around the application of BIM, the use of BIM in this manner overlooks the potential of BIM to construct and test virtual simulations of proposed schemes, to support design enquiry. A historical concern for the pedagogy constructed around the students’ design process is the application of methods and techniques that support the progression through the design process, (Ambrose, 2014; dash mei & Safari, 2018). This study examines the design process of architectural students and the interaction between analogue and digital methods used in design. These primary modes of communication, offer the opportunity to query the roles and rules of traditional architectural conventions around ‘problem finding’ and ‘problem solving’, challenging the ‘traditional’ design process examined by pioneers like Bruner (1966) and Schon (1987). These approaches are distilled from the findings of the study and presented as guidance to those teaching in architectural aBIMemia to align pedagogic goals to methods of abstraction in this new era of design education reconsidering digital methods in design.

source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 193–196
summary	To harness the potential of data-driven planning, it is imperative to conscientiously account for the unintended consequences inherent in the web of urban systems. A paramount issue revolves around the burgeoning societal disparities stemming from these complexities. When employing digital tools, data, and methods, it is crucial to uphold the principles of spatial justice. This pertains to the use of sophisticated participatory platforms but also extends to the tools utilized for land-use allocation, planning, and the analytical and simulation processes that underpin them. Furthermore, it is vital to recognize the significance of activism and self-organization as integral components in the introduction of novel urban ontologies.

source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 159–167
summary	This research investigates the use of LIDAR scanning, physics computational simulations, and ceramic 3D printing to streamline a process for generating a structural masonry bond-work from a given set of discarded pre-fabrication concrete parts. The research capitalizes on an initial set of large scale mockups developed using intuition based stacking of CMU Block detritus, which were in turn LIDAR scanned to produce a series of custom robotically 3d printed ceramic figural bricks to infill the gaps in a mortar based assembly. Following the proof of concept, the researchers explored computational means for simulating various configurations of aggregates using individually scanned broken blocks placed within a physics simulation. The outer boundaries are rigidly defined along with placeholders for desired apertures, and then the scanned detritus is dropped to inform a tight packed bond-work. The final digital aggregate is then run through a grasshopper simulation to derive the linework and print files for a robot to print the negative infill. This paper will discuss the ability for the designer to work within a computational process to produce structural envelope based construction with spoliated detritus towards new varied organizations embraces an aesthetic of visual reuse.

title	Machine Learning-based Optimization Design Workflow based on Obstruction Angles for Building Facades
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 15–24
summary	This paper proposes a ML-based optimization design workflow based on obstruction angles for the optimization of building facades (i.e. g-value and window width). The optimization output consists of the optimal clustering of windows in order to ensure a desired level of daylight provision according to method 2 defined in the EN17307:2018 (i.e. based on Spatial Daylight Autonomy: sDA) and to not exceed a maximum level of specific cooling capacity (SCC). The independent variables or design parameters of the parametric model are: room orientation/dimensions, window dimensions, and obstruction angle (??). The ML prediction models were trained and tested with reliable simulation results using validate softwares. The total number of room combinations is 61440 for sDA and SCC simulations. The development of reliable (90% of right predictions) ML predictive models based on decision tree technique were calibrated. The optimal clustering of windows was done first by floors and secondly by the designer’s need to homogenize the external facade with similar glazing properties and window sizes, having impact on the annual heating consumption. The proposed method help designers to make accurate and faster design decisions during early design stages and renovation plans.

title	Closing the Gap Between Research and Practice for Sustainable Urban Densification: Experiences and Findings from the RIS2023 Workshop
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 177–182
summary	More than the half of world population live in urban areas, and there will be an important need to densify cities. Urban densification will lead to cities with higher level of obstruction due to new surrounding buildings compromising daylight, energy consumption, view out, solar access among others sustainability aspects, which are often in conflict during renovation and early design stages of urban areas. There are novel fast design workflows based on prediction formulas that do not rely on the traditional and time-consuming approach based on daylight/thermal modelling-simulation. The main aim of this 7-hours workshop celebrated within the RIS23 international conference is to teach young designers how to use a novel urban densification method based on prediction formulas implemented as Grasshopper plug-ins in Rhinoceros. This paper describes the motivations of this workshop, a brief explanation of the design workflow taught and the different densification strategies proposed by each participant, highlighting their pros and cons as well as feedback of the design workflow itself.

summary	The historic centers have maintained their structure almost unchanged throughout various eras, thanks to a conservative approach that preserves valuable architecture and urban systems. The preservation of pre-existing structures can maintain the identity of a place, but it may also limit the flexibility of urban spaces that evolve over time in response to changing climates and functions. The study aims to develop a systematic and holistic workflow for creating temporary architectures that enhance the climatic and functional resilience of historical open spaces. Several disciplines are brought together for project development, including historical and climate analysis, algorithmic design, fabrication, and digital prototyping. As both climate and cultural changes are occurring rapidly, it is essential to educate the younger generation of students on effective methods. The technologies of algorithmic design, combined with digital fabrication, enable the creation of customized solutions that are more effective than standardized construction models. This paper reports on a methodological experiment for developing temporary pavilions in the courtyard of the Cloister of San Sepolcro in Parma, Italy.
