summary Existing buildings are often lacking BIM models. This paper proposes a method to semi-automate the generation of BIM models from 2D CAD drawings. The method has two parts: the first part, 2D CAD drawing preparation, involves cleaning the drawings to obtain simplified 2D input geometry and the second, 3D BIM model generation, involves generating and extracting parameters to generate 3D BIM components. This research focuses on the semi-automation of the second part. The the model is generated storey by storey, with each building element type being processed. A demonstration was carried out for a case-study building. The main modelling strategies used by the method are described and key challenges are discussed.

title Shape Exploration in Design: Formalising and Supporting a Transformational Process
source International Journal of Architectural Computing vol. 6 - no. 4, 415-433
summary The process of sketching can support the sort of transformational thinking that is seen as essential for the interpretation and reinterpretation of ideas in innovative design. Such transformational thinking, however, is not yet well supported by computer-aided design systems. In this paper, outcomes of experimental investigations into the mechanics of sketching are described, in particular those employed by practicing architects and industrial designers as they responded to a series of conceptual design tasks. Analyses of the experimental data suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules. A set of shape rules, formalising the reinterpretation and transformations of shapes, e.g. through deformation or restructuring, is presented. These rules are suggestive of the manipulations that need to be afforded in computational tools intended to support designers in design exploration. Accordingly, the results of the experimental investigations informed the development of a prototype shape synthesis system, and a discussion is presented in which the future requirements of such systems are explored.

title Programação em plataforma BIM e a Norma de Desempenho Brasileira: Desenvolvimento de uma aplicação para estimativa de performance acústica em projetos arquitetônicos [BIM platform programming and Brazilian Performance Standard: Development of an application to estimate acoustic performance in architectural design]
source SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.423-428
summary The Brazilian Performance Standard (NBR 15.575/2013 – Housing Buildings – Performance) is changing the design process of residential buildings, imposing new acoustic performance criteria. In this Context, the present paper proposes the programming of a Revit plug-in for verifying sound insulation of walls between environments, collecting information of the building’s model from a parameter database, calculating values of the elements’ sound reduction index and allowing to ponder constructive systems’ performance. The application aims to amplify productivity of designers and to provide greater control over technological solutions, assisting in the compliance with performance criteria.

summary Hospitalization is, for the patient, a neuropsychophysiological stressor, thus pertinent theories point to architectural stimuli as a tool for the homeostasis restoration and consequent well-being. Furthermore, they compile advantages to the patients’ treatment and highlight, mainly, the natural environments benefits, which is elucidated by the Biophilia theory. Through literature review and analysis of applied research in national and international hospitals, extracted from indexing databases of scientific production in the 2000-2020 timeframe, it was found that these areas [a] promote stimuli that enhance emotions and positive feelings; [b] act to restore stress and anxiety; [c] reduce pain, analgesic intake and length of stay; and [d] increase patient satisfaction. By sharing the results of this research, the objective is, in addition to stimulating future research on the organism behavior in the environments, to indicate perspectives for hospital ambiences.

title Digital Creativity: Pedagogical Strategies for Design Teaching

summary This paper presents a discussion about design pedagogy strategies focused on students’ processes rather than on their architectural objects. The hypothesis here is that critical and creative autonomy of students can be developed by the teaching of design thinking simultaneously with operative digital tools within design disciplines. An experiment was made in an introductory design discipline in a private Brazilian Architecture School and results show how students’ skills and knowledge about design grow faster when a digital creative culture is fostered within the design studio.

summary In order to design an ephemeral pavilion located at the Serpentine Gallery (England), an experimental design approach was developed in this paper by using biomimicry strategies associated with parametric modeling. Exploring the solution-based methodology, the analysis of the sartorius muscle anatomic features such as rotation, flexion and long shape allowed inspiring the proposal of a Sartorius Pavilion which is the object of study. The experiment was implemented throughout a parametric visual script tool resulting in a model capable of rapidly and intuitively simulating shape variations, basic structural and material attributes by modifying a set of previously defined parameters.

summary The World is experiencing a rapid surge in urban population, in addition to fast urbanization processes. Contemporary cities witness the rise of numerous urban and social problems, leading to the emergence of informal settlements. Still, computational and parametric resources have increasingly been adopted in novel approaches to urban planning and design. These resources can be used in informal settlements to improve urban quality without losing their essential features. This paper describes a teaching experience in the context of a design studio that uses shape grammars and parametric tools to design for an informal settlement context in Ahmedabad, India.

title Algorithmic approach toward Transit-Oriented Development neighborhoods: (Para)metric tools for evaluating and proposing rapid transit-based districts
source International Journal of Architectural Computing vol. 14 - no. 2, 131-146
summary This article focuses on the use of computational tools to provide dynamic assessment and optimized arrangements while planning and discussing interventions in urban areas. The objective is to address the use of algorithmic systems for generating and evaluating urban morphologies guided by Transit-Oriented Development principles. Transit- Oriented Development is an urban development model that considers geometric and measurable parameters for designing sustainable cities. It advocates compact mixed-use neighborhoods within walking distance to a variety of transportation options and amenities, seeking to result in optimized infrastructure provision and energy-efficient low- carbon districts. This article presents algorithmic experiments for the optimization of a rapid transit district, through its urban morphology and services’ location, providing an accurate Transit-Oriented Development modeling. The main findings of this study highlight that the combination of Transit-Oriented Development and algorithmic–parametric tools has the potential to significantly contribute to a process of responsible planning and, ultimately, to mitigate global warming.

summary This paper investigates computational optimization techniques at the urban design scale, aiming to improve the performance of urban fabric layouts according to predefined evaluation metrics. To this end, this work addresses the use of optimization tools in urban design by comparing various optimization algorithms for generating urban fabrics with improved walkability and by analyzing the outcomes of different urban design rules. These rules formulate orthogonal and non-orthogonal grids from the perspective of transit accessibility (TA), thereby minimizing automobile usage and improving the walkability of neighborhoods. Transit accessibility is also evaluated alongside estimated infrastructure cost to verify the suitability of applying optimization in urban design. Our results suggest that the RBFOpt algorithm performs best for generating urban fabrics according to our quantitative design objectives; more flexible and complex grids in terms of shape and dimensions tend to deliver greater TA than rectangular and uniform-oriented grids; different block patterns can lead to solutions more directed at TA or to infrastructure cost, outlining a trade-off; and multicriteria optimization helped in identifying designs that balanced transit accessibility and infrastructure cost.

summary This paper presents a computational approach to provide dynamic assessment and optimization of principles derived from Transit Oriented Development (TOD) - an urban development model that advocates compact, walkable, and mixed-use neighborhoods, centered around transport stations. In spite of being increasingly promoted in several cities of the world, TOD lacks an approach that addresses multivariate data for optimization of its principles. In this paper, we propose a methodology backed by an algorithmic-parametric CAD environment, applied to a neighborhood unit in a case study. The objective is the analysis and improvement of TOD relevant and measurable features (transit accessibility, walkability and diversity) in order to optimize neighborhoods' features. The ultimate goal is to facilitate the management of solutions in TOD planning processes, supported by a principle-index-tool approach triad.

summary Many different types of algorithms have been associated to gain complex shapes. They give rise to a large set of unusual forms, through calculations based on computational geometries, self-organizing systems, rule-based systems, and optimization, often still assembled in morphogenesis principles. Many of these discoveries mimic physical, chemical, and even behavioral principles at the edge of this code-translated knowledge. Thus, any new form, the result of this exploratory perspective, can mean some progress. If the understanding of specific algorithmic characteristics has validity (for precise programming), generic concepts are also important for simplifying procedures and presenting general concepts of the result.
