Este trabalho apresenta um estudo de caso detalhado sobre a contribuição do software PVSyst  para a elaboração de um projeto de sistema fotovoltaico residencial na cidade de Uberlândia-MG. Nesse projeto, são apresentadas todas as principais funcionalidades do software, acerca do dimensionamento de um sistema fotovoltaico on grid, no qual será avaliado a irradiância solar em função do tempo, eficiência dos módulo fotovoltaicos e a associação dos módulos propostos em função do acoplamento com o inversor. Dessa forma, será possível uma visão geral da eficiência do sistema proposto e suas possibilidades práticas, de modo que o projetista e o cliente tenham uma visão completa do projeto a ser realizado e encontrem juntos uma forma para maximizar o investimento.

In various sectors and industries, the use of digital design drawings has enabled the collection and visualization of relevant job data. The emergence of the CAD system changed several branches of the design segment and until today it is one of the main methods used. However, the evolution of society and technology culminated in the development of the BIM methodology, seen by many as promising in the design of projects, as it allows graphic improvements while integrating the project participants in the different phases of the work. Such an approach becomes information focused by exploring parametric and 3D representations of virtual models. In this article, both CAD and BIM contributions to the industry are raised through a case study of a residential electrical project developed by the company CGWorks.

Present in several engineering and architecture projects, the BIM methodology, applied in 3D modeling projects, has become a work tool for several professionals in the AEC (Architecture, Engineering and Construction Industry) in the last decade [1]. This change possibly altered the way projects are represented and even initially conceived. In this sense, an important part of the BIM process is related to the generation and design of virtual models, since the decision on the type of graphic representation of such objects will guide the decision making of the project as a whole [2]. In relation to the type of modelling, parametric, informative and artistic ones usually stand out. Therefore, this work aims to analyze and compare such design approaches to verify which applications are more interesting for each use case.

The complexity of contemporary engineering, allied with the necessity to reduce the distance of communication between the contributors of a project, requires the development of new technologies and methodologies. In this bias, it is noticed the great utility that Virtual Reality
