Análise do potencial de geração fotovoltaica usando metodologia BIM

Abstract

This study has the purpose of analyzing the potential of photovoltaic (PV) generation in the blocks of the Instituto de Cultura e Arte (ICA), in the Centro de Convivência and in the Restaurante Universitário (RU) using the BIM methodology. The research presents the factors of constructive analysis, sustainability and costs for specific works in these blocks, involving technical design, calculation of PV design, study of financial attractiveness and comparative with an energy currency. For this, Revit software is used for three-dimensional modeling focused on the volumetry of buildings and also on the study of shading, in which, for each block, the effects of shadows are simulated during three periods of the day and for four months a year, equally spaced. The use of this methodology represents a new level in the integration of engineering projects, creating an integrated platform for the simultaneous development of all constructive and financial details, although it is not yet very widespread among professionals. The RETscreen software is used to measure the investment to be made in each construction, how much can be saved per year and how long that investment is fully paid. In this study, it is observed that ICA is available to implement 856 modules, while the Centro de Convivência can deploy 4065 modules and RU 1789 modules. As a result, the unities can respectively generate 366.67 MWh, 1745.58 MWh and 766.34 MWh. For each of the blocks analyzed, a return of investment of two and a half years is realized, requiring the ICA to invest R$ 4,686,250.00, for the Centro de Convivência R$ 984,400.00 and for the RU R$ 2,057,350.00. In addition, the project also provides an analysis of carbon credits from the premises of the Kyoto Protocol.
