In recent years, the design process in architecture has experienced significant increments arising from computational design, which allowed the exploration of design alternatives in real time based on parametric modeling. In the building's design, understanding most of the measurement systems in the context of natural ventilation could drive the decision-making process from the tests with computational simulations. This paper attempts to determine the flow pattern of natural ventilation in indoor environments under specific conditions from the CFD Ansys Fluent® R22 comprising five configurations analyzed comparatively to a control sample. Respecting the scientific reductions and using computational techniques for measurement from Aeronautics, satisfactory inferences were registered. We concluded that the diagonal positioning of the openings substantially accelerates the wind speed in indoor environments. This design strategy overrides the proposition of more openings when the intention is to increase the speed and renewal of indoor air.

The thermo-energetic performance of buildings is closely related to the local climate, making it necessary to align the architectural space with the climate and human needs. The State of Mato Grosso has high temperatures in the hottest months, and most buildings don’t reflect the existing climatic conditions. Therefore, it’s essential to study the local climate and the most appropriate bioclimatic strategies for each municipality to establish design guidelines aimed at the adaptability climate of buildings. Thus, this work aimed to identify bioclimatic strategies and propose design guidelines for climate adaptability of buildings for Água Boa, Campo Verde, and Comodoro, based on the climatic characterization of the municipalities and study of the construction guidelines indicated in the ABNT NBR 15220-3 standard. To this end, the cities' climate analysis was carried out using the CBE Climate Tool. Plotting the psychrometric charts in the Climate Consultant 6.0 software showed the most relevant bioclimatic strategies. Finally, we verified the design guidelines recommended by the standard. Although Água Boa and Campo Verde are in the same bioclimatic zone and have the same climate, the results showed that Campo Verde's climate profile is closer to Comodoro. We identified some differences between the design recommendations established by the software and the standard, which influence the percentage of hours in which we need active conditioning of the environment. Based on this, we create a table with the most suitable construction guidelines for each municipality, aiming at the thermal comfort of users and better thermal performance of buildings.

In the context of the Brazilian electrical sector, there are no references regarding the application of BIM (Building Information Modeling) and GIS (Geographic Information System) in construction and maintenance of Electric Power Substations. Thus, this work proposes the integration of these technologies, since previous experiences in other engineering fields have shown promising advances that could be useful for the management and maintenance of the electrical power market. By associating these technologies, it is possible to obtain a more accurate mapping of the information related to the assets, arrangements, cabling, electronic components, etc. Moreover, to have this integration working properly, it is required to also provide a three-dimensional geometric database of the entire set of the electric power substation active components. In fact, the insertion of one model into a particular point of the substation project allows constructive, operational and maintenance information. Therefore, by combining BIM and GIS in the modeled families, it is possible to obtain more consistent information during the construction or maintenance phase. This will provide advantages in decision making, resources within the corporate communication and a better understanding of the environment related to an electrical energy substation. Additionally, the location conditions and the surroundings of the substation would be more precise and pertinent since the components of the substation will be come georeferenced. The association between these two platforms allows a more intuitive overview of the project, making the make then adherent to the planning, design, construction, operation, preventive and corrective maintenance. So, when applying these tools together, the company will obtain results almost immediately, since all managing features will be accessed through only one integrated information database. This proposal presents the very first results of the integration of BIM and GIS, in the context of a Brazilian electric company- Furnas Energy. Implementation results of the solution in the context of substations of the company are discussed and shows the availability of reducing construction/maintenance costs, alteration planning, logistics, prevention of possible accidents and the possibility of updating information in real-time.

The application of BIM for ease of operation and maintenance is an emerging area, especially when the focus is on energy management. The use of BIM as a database and systems with the ability to visualize them is the main point addressed in BIM-O&M research. However, challenges with interoperability, the definition of requirements for O & M, and a feasibility analysis of BIM implementation costs in this phase have fewer scientific investigations. This research explores alternatives to the obstacles of loco manipulation of BIM models in Electrical Engineering through a case study of an electromechanical device in an electric power substation.

The development of digital technologies and the possibilities of design exploration with more integrated approaches to natural elements, has found space in architecture for paths ways and experimentation that previously, due to the absence of adequate tools, were limited or unthinkable. Biomimicry and parametric modeling are inserted in this context as potential resources for innovation in creative processes and the ability to respond to answer the challenges of emerging complexities of architecture from this perspective. However, its diffusion has encountered difficulties, given the lack of computational instruction among professionals, as well as epistemology about the real potential of computers as a tool in the creative act. The objective aim of the article is to reflect and discuss the interfaces and impacts that the biomimetics approach and parametric modeling can engender on the creative act in project teaching. In this way and from a qualitative and experimental approach to elucidate such questions, a directed literature review was combined with a didactic experiment carried out in two stages (traditional and digital methods in the design process) and with two distinct groups of students (phase initial and final graduation). It was found that the cognitive barriers in relation to representation was a challenging variant from the point of view of implementation in teaching. However, which it implies a propensity for hybrid use of the methods applied in the two phases, denoting that the use of parametric modeling has become more compatible in experiments with biomimetics for creation compared to creation methods and tools in traditional design teaching.

Chaotic urbanization processes in Brazil have led to numerous problems in current urban spaces, such as the sprawling of cities. This problem points to the need to improve urban planning methods capable of guaranteeing sustainable development. In this sense, understanding that a possible solution is urban densification, the present case study of Santa Maria neighborhood in Uberlândia-MG, Brazil, uses an agent based model to simulate the repercussion of this densification on local traffic. The results show current urban infrastructure would not be able to support estimated population growth, causing new problems such as conurbation and overloading of services. Therefore, despite being helpful, consolidation should take place in stages and with uniform distribution throughout the city, ensuring that no region is overwhelmed.

From the 2000s, the notions of interoperability and compatibility earn strong semantics, mainly due to the bringing together of new disciplines in project environments. As a result, to explore the current limits of integration layers, this paper presents tests using neutral standards and native modeling tools, which, in turn, are sufficient for simple data exchanges. From the results, we made some conclusions about the association of architecture and hydrosanitary projects, which, respecting the qualitative reductions and without intentions of generalization, presenting distances from full interoperability.

DARIVA, M.; ARAUJO, A. The Potential of BIM in Disseminating Knowledge about Decentralized Wastewater Treatment Systems: Learning through the Design Process. Water, v. 13, n. 11, Basel: MDPI, 2021. DOI: 10.3390/w13111504
Despite the low rate of sewer service coverage in developing countries, especially in small towns and rural areas, decentralized wastewater treatment systems (DEWATS) are alternatives to ensure public health. Nonetheless, understanding the physical or functional aspects of these system constructions remains difficult when there is no bibliography, a teaching professional, or even a prototype that allows technical conclusions about specific processes. Although resource combina tion in a BIM environment works as a facilitator to obtain compact and sustainable results, the pur pose of this collaboration is not only to simplify the design process. This paper aims to propose a way to use BIM concepts as a learning tool throughout the modeling process. To do so, we devel oped a BIM template with specific DEWATS characteristics in order to provide not only information needed for construction, but also information that can favor learning. We measured how much the level of development (LOD) can influence learning about these systems during the design process, directing users to make the best implementation choices. The adoption of qualitative analysis of a questionnaire answered by three groups of professionals (general CADD software users, BIM soft ware with generic template users, and BIM software with specific DEWATS template users) allowed us to identify differences among them, such as the number of DEWATS known, considered LOD, learning, and handicaps in the design of these systems. The results pointed out that the BIM tools can influence learning about new and unknown specific systems, which is directly related to the LOD of a model.

(eds) Proceedings of the 18th International Conference on Computing in Civil and Building Engineering. ICCCBE 2020. Lecture Notes in Civil Engineering, vol 98. Springer, 2021.

Brazil has more than 23 million inhabitants in rural areas without adequate sewage collection or treatment, which corresponds to 75% of the rural population. The absence of adequate sanitary conditions can cause disease and harm the environment. Decentralized wastewater treatment systems are alternatives to ensure the health of the population and at the same time maintain the environmental integrity of these locations. However, several projects in this area do not include important data for the construction, good performance, and operation of these systems. This partially nullifies the benefits of collecting and treating effluents. Currently, the Building Information Modeling (BIM) methodology fits into this scenario as a possibility for technological innovation and progress in productivity and project presentation. However, there are two barriers to the implementation of this technology in the production of hydraulic and sanitary projects: the scarcity of studies related to the management of the design process of these systems and the lack of BIM components that represent decentralized wastewater treatment systems. This work presents the development of a technological artifact with the potential to fill these gaps: a template created in Autodesk Revit software with several components of decentralized wastewater treatment systems available for use in projects. It is not simply a catalog in which the designer can choose the equipment to be used, but components that provide productivity in the project design, learning and flexibility in the construction of the models, fitting to the market standards.

The use of Augmented Reality (AR) systems in construction processes can represent an essential transformation in the communication between design and production. However, supposing that design-production translations can be obtained from several manufacturing methods (such as robotic, manual, modular, non-modular, and others), there are not enough studies that explored the potential uses of AR as an assistant for assembly operations. To tackle this problem, this ongoing research proposes to investigate the potentials of a low-cost and marker-based AR system to conduct different manual assembly processes. With the observational focus on aspects of precision and feasibility, we used scientific reductions based on modeling, simulation, and prototyping to provide inferences about the proposed tool's behavior in the real world.

The BIM (Building Information Modeling) concept is the digital representation of all elements, containing all the physical and functional characteristics and the graphical and non-graphic representations of a building. On this platform, it is possible to obtain all the information about a building life cycle in a project. The present work aims to analyze the use of BIM technology in the elaboration of projects applied to the hydrosanitary system. One case was analyzed: the transfer of a multi-storey building hydrosanitary project, done in CAD (Computer Aided Design), to the BIM platform. In the end, it was possible to make a comparison between the use of CAD and BIM, propose compatibilization solutions and evaluate the possibilities of this technology application in the elaboration of hydrosanitary projects.

Nos últimos anos, tem sido crescente o uso de tecnologias digitais na prática da arquitetura por meio dos laboratórios de fabricação digital, configurando-se historicamente como base de catalisação e transformação dos métodos de concepção e produção do espaço. Entretanto, o que antes tinha seu uso aplicado a modelos de representação e comunicação em arquitetura, atualmente, procura sua inserção por meio de uma renovação sistêmica frente aos processos de projeto arquitetônico e de fabricação de componentes construtivos através das possibilidades geradas pelo design computacional. Essa situação, tem contribuído para uma difusão de recursos tecnológicos e para a implantação de novos métodos de concepção, nos levando à reflexão principal deste artigo: de que modo essa realidade tem influenciado e/ou contribuído, tanto no que diz respeito ao ensino quanto nos desdobramentos para a produção do espaço como forma/matéria? Para esta discussão, utilizou-se uma metodologia de natureza exploratória qualitativa, utilizando-se de revisão literária, com ênfase especial no caso do IAU-USP São Carlos, evidenciando de modo introdutório, outros laboratórios em centros de ensino de arquitetura no Brasil onde essas estruturas tecnológicas têm tido seu uso inserido no exercício de projeto. Segundo o referencial consultado, observa-se o crescimento de forma exponencial da implantação desses laboratórios nos centros de ensino, com sua concentração de implantação maior na região sudeste do país, sendo os mesmos em grande parte com ações de desenvolvimento tecnológico incorporadas à arquitetura. No Brasil, há pouco mais de 30 anos, escolas de arquitetura e urbanismo têm procurado inserir em suas disciplinas algumas destas tecnologias, no entanto, de forma isolada ou com o objetivo maior de apenas fornecer bases mercadológicas para atuação profissional. Os aplicativos CAD são pioneiros dentro deste contexto. Com os casos apresentados aqui, bem como o debate teórico apresentado pelos autores, percebe-se que há uma pluralidade no uso das tecnologias digitais como ferramenta do processo criativo. Tal cenário desafia arquitetos e alunos a refletirem a prática da arquitetura, principalmente de forma crítica, bem como sobre o ensino, a fim de repensar suas estruturas escolares e seus currículos, diante das renovações necessárias.

Since the publication of the book Performance architecture: beyond instrumentality (KOLAREVIC and MALKAWI,2004), architects have used a good performance as a guideline for the projects. This research proposes to investigate the possibilities and limitations of one of the guidelines through the incorporation of instantaneous aerodynamics in the parametric design context, from the use of parametric modeling techniques, electronic microcontrollers and computational extensions to promote the connection between them. From the construction of this artifact, we expect to develop strategies for including performance simulations in the processes of synthesis in architecture.
