title	Análise da Emissão de CO2 em Edificações através do Uso de uma Ferramenta CAD-BIM [Analysis of CO2 emission in construction using a CAD-BIM system]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The main objective of this research is to determine through the use of a CAD-BIM system, the emission of CO2 in the pre-operational phase of construction. Based on a case study in quantitative analysis of materials and the BIM system, it was possible to quantify the amount of CO2 emitted during the pre-operational life cycle of a building. By using this feature you can provide, before the begining of construction, the total CO2 that will released to the environment, and other analysis.

title	Data Mapping and Ornament in Digital Craft

source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 110-120
summary	With an ever-increasing index of digital artifacts, we have begun to exhaust variation as an adaptive technique. The problem with incremental modulation (here understood as sequential and slowly progressing change of a set of parameters within a field condition) is that in essence it leads to morphologically equivalent and, hence, repetitive patterns of habitation. While the role of variation proved key in pushing forward an essential body of research testing and optimizing principles of mass customization, its residual effects become critically disconcerting. This paper presents an investigation of tectonic mutations for the generation of form, seen through data simulation experiments and machining artifacts. Through several projects we investigate the effects of ornament created as a result of the new relationship between generative modeling, simulation, and fabrication in the digital age. Subject to (de)generative mutation techniques, ornament can be under-stood as a result of overlaid data, whether the data is performance related or not, in both massing and surface conditions. This new working methodology will mitigate between the incertitude regarding time, history and memory, and by reinventing their relation it will reassess ornament’s agency within the digital culture. Design methods are extended by exploring, collecting, analyzing, and representing data through various materialization processes. Design is therefore reconsidered as being injected with the concepts of data driven design and dependent on the inter-play between performance and aesthetics. In this way, we consider the footprint - or the subsequent impact - of the human onto the nonhuman using artificial intelligence as a medium. These intentionally or accidentally engraved layers of information begin to describe potential trajectories of novel survival modes in the Anthropocene.

title	Material Response: Technology, Material Systems and Responsive Design
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_20
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	This paper investigates the role technology and materials play in making meaningful connections between people, architectural space and the workplace. It indicates that design can synergize with responsive technology and material systems to leverage new power for future workplace interaction design. We have created a spatial prototype paired with a series of simulations that act as a proposal to stimulate workplace interaction. The project employs a responsive ceiling that combines a fluid computational pattern with temperature-responsive bi-material laminates with thermochromic coatings and electrically programmed micro-controllers. The project is then connected to a computer code that computes readings based upon ongoing interactions with humans wearing body sensors. The methodology categorizes the simulation results into aroused states and calm states. As the computational patterns and colors change, we are made aware of the relationships between space, technology, and the human sensorium. This conversation brings insight into how we can design more effectively for workplace interactions.

title	Bio-digital Sand Logics: Dune Sand Material and Computational Design
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_35
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This paper discusses the creation of a new sand-based material, performative testing, and the computational logic involved in the design of a prototypical architectural system. Dune sand is known to be an unstable material compared to river or marine sand and as a result it is not normally used for construction. Because of this, desert regions have grown a reliance upon imported materials creating massive sustainability issues due to large scale global shipping, importation and resource extraction. This research indicates there is a viable opportunity to leverage dune sand as an ongoing line of inquiry for material science and design in local desert regions. It establishes that there is very little architectural research being done in this particular area. The methodology begins with experiments in bio-material using dune sand as a compound, and then establishes a construction system based upon a manifold of experiments. Along with material investigations, the process uses a Scientific Testing Method (STM) and Hypothesis in Action (HIA) as part of the testing methodology.

summary	Arbor is a data spatialization of the urban forest of Palo Alto, California. The sculptural installation consists of 120 ribs arranged radially within King Plaza fronting Palo Alto City Hall. It uses the database of over 45,000 public trees in the city’s Open Data Portal (City of Palo Alto, n.d.) as the basis for a collective, three-dimensional map of one aspect of the city’s ecology. The installation performs like a compass, with each rib corresponding directionally to a respective “pie slice” of territory raiding outwards from City Hall. The trees are represented by bumps on the outer edge of each rib, so the zones with more trees result in ribs with more relief. The ribs are arranged in a circle, gradually changing in height, profile, and color to create a dynamic form that is different from each side

summary	This paper describes the Buoyant Ecologies project, an ongoing research collaboration between architects, marine ecologists, and manufacturers focused on developing integrated architectural, ecological, and material responses to climate change and sea level rise. The research employs techniques of design computation and robotic fabrication to develop an approach to coastal resilience that is rooted in material performance as it relates to marine habitats. The project explores the design and production of highly performative fiber-reinforced polymer substrates that interact productively with the underwater ecosystem to promote multi-scalar habitats for invertebrate animals, encouraging ecological diversity and serving as wave-attenuating structures that mitigate coastal erosion. In this regard, the research leverages computational workflows of modeling, simulation, and fabrication to interface between human and nonhuman species in a way that benefits the broader ecosystem. The paper discusses an iterative prototyping process that has led to the design and construction of the Float Lab, a larger-scale prototype of a floating breakwater.

title	Drawing Codes. Experimental protocols of architectural representation
doi	https://doi.org/10.52842/conf.acadia.2018.046
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 46-55
summary	Emerging technologies of design and production have largely changed the role of drawings within the contemporary design process from that of design generators to design products. As architectural design has shifted from an analog drawing-based paradigm to that of a computational model-based paradigm, the agency of the drawing as a critical and important form of design representation has greatly diminished. As our design tools have increasingly become computational and the production of our drawings have become predominantly automated, this paper examines the effects on the architectural discipline and attempts to catalog examples of how artists, designers, architects, and programmers have used rule-based techniques in the process of drawing as a critical act in their process. Furthermore, the paper presents the Drawing Codes project, an ongoing research and exhibition platform that critically investigates the intersection of code and drawing: how rules and constraints inform the ways architects document, analyze, represent, and design the built environment. The project features commissioned drawings by a range of contemporary architects and designers as a means of gathering a diverse set of perspectives on how computational techniques, but more importantly, computational thinking, can reexamine the role of architectural drawing as a creative and critical act.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 160-165.
summary	This project melds digital and analog workflows to test methods for integrating digital fabrication into traditional practices of rammed earth construction. Developed in two separate workshops with students at the University of Minnesota and California College of the Arts, the research experiments with the use of digitally-fabricated form liners in the production of rammed earth modules that can accommodate a variety of variable and performative textures (Figure 1). The work includes material experimentation to test optimal mixtures, compositions, tamping techniques, and the possibilities of including bio-based, recycled, or harvested materials. Custom fabricated liners are integrated into conventional formworks to produce highly variable earthen modules, conceived as an alternative to concrete and other more carbon-intensive materials.

title	Daylight Simulation: Validation, Sky Models and Daylight Coefficients
source	De Montfort University, Leicester, UK
summary	The application of lighting simulation techniques for daylight illuminance modelling in architectural spaces is described in this thesis. The prediction tool used for all the work described here is the Radiance lighting simulation system. An overview of the features and capabilities of the Radiance system is presented. Daylight simulation using the Radiance system is described in some detail. The relation between physical quantities and the lighting simulation parameters is made clear in a series of progressively more complex examples. Effective use of the inter-reflection calculation is described. The illuminance calculation is validated under real sky conditions for a full-size office space. The simulation model used sky luminance patterns that were based directly on measurements. Internal illuminance predictions are compared with measurements for 754 skies that cover a wide range of naturally occurring conditions. The processing of the sky luminance measurements for the lighting simulation is described. The accuracy of the illuminance predictions is shown to be, in the main, comparable with the accuracy of the model input data. There were a number of predictions with low accuracy. Evidence is presented to show that these result from imprecision in the model specification - such as, uncertainty of the circumsolar luminance - rather than the prediction algorithms themselves. Procedures to visualise and reduce illuminance and lighting-related data are presented. The ability of sky models to reproduce measured sky luminance patterns for the purpose of predicting internal illuminance is investigated. Four sky models and two sky models blends are assessed. Predictions of internal illuminance using sky models/blends are compared against those using measured sky luminance patterns. The sky model blends and the Perez All-weather model are shown to perform comparably well. Illuminance predictions using measured skies however were invariably better than those using sky models/blends. Several formulations of the daylight coefficient approach for predicting time varying illuminances are presented. Radiance is used to predict the daylight coefficients from which internal illuminances are derived. The form and magnitude of the daylight coefficients are related to the scene geometry and the discretisation scheme. Internal illuminances are derived for four daylight coefficient formulations based on the measured luminance patterns for the 754 skies. For the best of the formulations, the accuracy of the daylight coefficient derived illuminances is shown to be comparable to that using the standard Radiance calculation method. The use of the daylight coefficient approach to both accurately and efficiently predict hourly internal daylight illuminance levels for an entire year is described. Daylight coefficients are invariant to building orientation for a fixed building configuration. This property of daylight coefficients is exploited to yield hourly internal illuminances for a full year as a function of building orientation. Visual data analysis techniques are used to display and process the massive number of derived illuminances.

title	Development of a Decision Support Tool for Bamboo Building Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The design process of a bamboo building is sometimes very complex for building designers, since there is no accepted design methodology for it. This process may be caused by a lack of relevant information provided to the designer. Based on this issue, this paper proposes a decision support system for application in bamboo building design that might be helpful for the designer in his/her design process. For this purpose, a decision support tool for bamboo building design process is being developed. Thedevelopment of the tool uses approaches, i.e. a taxonomy of bamboo building to identify the design problems, IDEFÆ to model the decision support tool, and develops a dedicated tool for Bamboo building design process. This tool has been tested in an international bamboo-housing workshop, hence results, suggestions, and recommendations from the workshop will be analysed. With this tool, the bamboo-building designer can make a bamboo building design in a systematic way. This tool also helpsthe designer to be as best informed, explicit, correct, and complete as possible during the design process.

title	Development of a decision support system for bamboo building design
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Bamboo, the fastest growing woody plant, is used as a common building material in bamboo-growing countries and recently also in non-bamboo-growing countries. In spite of this fact, building designers or users of a building have problems using bamboo as a building material since they lack information and guidance in how to use bamboo. This paper proposes a decision support system (DSS) that might be useful for designers when they design a bamboo building. It presents an early-stage design process of bamboo building and the development of a DSS. The architecture of this system is based on the theory of DSS and knowledge of bamboo that should be integrated in the design process of bamboo building. So there are three components: a DSS, design process, and knowledge of bamboo. The process starts with determination of the building system, database construction of bamboo building parts, and the rule for using bamboo in each building part. The process focuses on systematisation of each design stage and integration of the building parts to construct a monolith bamboo building. The purpose of systematisation is to offer designers a means of categorising problem solving during the design process in terms of, for example, assumption, criteria, alternatives, and acceptable solutions.

summary	The body of work that follows discusses an experimental computer-aided methodology for design and planning processes that detects and amplifies potential and beneficial connections between urban parks and metropolitan forest patches, using as media roads and streets and their existing vegetation. Technically, it introduces a computational protocol to gather and process georeferenced data necessary to run through CircuitScape a set of structural connectivity analyses in urban contexts. In order to overcome the barrier of local data accessibility, the methodology exploits Google Earth Engine to cross-read OpenStreetMap data with local NDVI imagery, allowing to calibrate the connectivity analysis on current ecological performances. The outputs of the analyses highlight key road segments where vegetation should be reinforced, and therefore, identify specific areas or streets of interest for intervention.

title	The Customized Habitat: An Exploration of Personality-Induced Mass Customization through Shape Grammars
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 450-464
summary	Despite its economic efficiency, mass production fails to appeal to the very people it is meant to accommodate. Mass customization, on the other hand, allows for the consideration of personal differences. Nonetheless, it is a process that requires more time, effort, and resources, hence the reliance upon mass production. Previous research showed a potential impact of personality on perceptions of the architectural space. The research investigates the applicability of mass customization in the architectural domain using MBTI (Myers–Briggs Type Indicator). Using MBTI, we surveyed 187 individuals to investigate the correlations between personal traits (mind, energy, nature, tactics, and identity) and preferences of architectural aspects (exposure, circulation, view, plan layout, and interior colors). The survey draws on how multiple fields have successfully applied MBTI to increase the value they provide. The findings present a novel contribution to architectural research as they demonstrate an actual connection between MBTI personality patterns and architectural preferences. In addition to several interaction patterns, our results strongly support an effect of the mind aspect on view preferences as well as an effect of energy on three architectural aspects: view, plan layout and interior colors. Shape grammars were then created, based upon these correlations, in order to provide a basis for optimized mass customization. The optimization/automation of this process will result in a more habitable space in which neither personality differences nor valuable resources are sacrificed.

title	Simulating Human Senses to Improve Thermal Comfort
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 689-702
summary	Between the synergies of environmental perception and technological advancement evolves the parallel world of the metaverse. Evolutionary virtuality intends to aid humanity in envisioning the threatened future of cities under environmental risks through tailored features. Traditionally, the sense of sight – which is the focus of virtual reality – has dominated the architectural practice. However, architects and urban designers have begun incorporating other senses into their work over the recent decade. The expanding understanding of the multimodal nature of the human mind that has evolved from cognitive neuroscience research has received little attention so far in the architecture field. This paper investigates the role of synthesized sensory experiences – such as visual, auditory, olfactory, gustatory, and thermal sensations – in designing revolutionary settings that aim to improve people’s interactions with their surrounding environments. A 15-minute experiment of an immersive experience in an office setting using virtual reality headsets is utilized to explore the role of multimodal sensory integration towards tolerance to the thermal environment. The findings revealed significant potential in using multiple senses – especially gustatory – to design thermally comfortable spaces. It is hoped that architectural design practice would progressively include our developing understanding of human senses and how they interact. This holistic approach ought to lead to the development of multisensory-inclusive workspaces that promote rather than hinder our social, cognitive, and emotional development.

title	Low-cost Portable Wireless Electroencephalography to Detect Emotional Responses to Visual Cues: Validation and Potential Applications
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 139-154
summary	This paper validates the using a low-cost EEG headset – Emotiv Insight 2.0 – for detecting emotional responses to visual stimuli. The researchers detected, based on brainwave activity, the viewer’s emotional states in reference to a series of visuals and mapped them on valance and arousal axes. Valence in this research is defined as the viewer’s positive or negative state, and arousal is defined as the intensity of the emotion or how calm or excited the viewer is. A set of thirty images – divided into two categories: Objects and Scenes – was collected from the Open Affective Standard Image Set (OASIS) and used as a reference for validation. We collected a total of 720 data points for six different emotional states: Engagement, Excitement, Focus, Interest, Relaxation, and Stress. To validate the emotional state score generated by the EEG headset, we created a regression model using those six parameters to estimate the valence and arousal level, and compare them to values reported by OASIS. The results show the significance of the Engagement parameter in predicting the valence level in the Objects category and the significance of the Excitement parameter in the Scenes category. With the emergence of personal EEG headsets, understanding the emotional reaction in different contexts will help in various fields such as urban design, digital art, and neuromarketing. In architecture, the findings can enable designers to generate more dynamic and responsive design solutions informed by users’ emotions.

title	BEYOND ANALYSIS AND REPRESENTATION IN CAD: A NEW COMPUTATIONAL APPROACH TO DESIGN EDUCATION
source	Submitted to the Department of Architecture in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Architecture: Design & Computation at the Massachusetts Institute of Technology
summary	This thesis aims at changing students' attitude towards the use of computer-aided design (CAD) in architecture. It starts from the premise that CAD is used mostly for analysis and representation, and not as a real design aide, and that architecture students have a bias against learning computer programming. For this purpose, a prototypical instruction system that mixes computer-aided design and computational design theory was developed, based on a series of fundamental concepts that are common to both fields. This system was influenced by Mitchell's (1987) The Art of Computer Graphics Programming and Stiny's (1976) shape grammars. Despite being based on solid theoretical foundations, CAD has progressively become an exclusively practical tool, since its origins in the 50's and 60's, while computational design theories have been mostly restricted to the academic circles. This thesis proposes an inversion in the present situation: the study of CAD theory, and the application of computational design into practice. The system proposed provides a conceptual framework that can be adapted to different circumstances, including course formats and resources, as well as students' background and technical training. It is based on seven fundamental concepts from computational design theories that are also important to the study of shape grammars: symmetry, recursion, rule-based compositions, parameterization of shapes, generative systems, algorithmization of design procedures, and shape emergence. These concepts are introduced within a CAD context, where their practical implementation and experimentation are possible, focusing the understanding of the computational nature of design. During this research, the proposed system was tested in two case studies with students from schools that had contrary orientations in terms of the importance of CAD in the architectural curriculum. In these experimental courses, students' activities evolved from using a commercial CAD tool in an innovative way, to the use of programming techniques for creating meaningful tools. Despite not having a statistical reach, the fieldwork allowed drawing preliminary conclusions about the proposed system's efficacy, since virtually all the students reported changing their understanding of the role of CAD in architecture, while some also acknowledged a conceptual influence in other subjects and in the way they see architecture.
