Metodologia de apoio à concepção de sistemas fotovoltaicos integrados à arquitetura por meio de ferramentas operacionais: estudo de caso para um projeto em Curitiba

Abstract

The work addresses aspects involved in the design and evaluation of Building-integrated photovoltaics (BIPV) under the premise of sustainable technological development. The theme is presented through literature review, under technical, environmental, aesthetic-constructive and economical optics. It proposes a case study in Curitiba - PR - Brazil, by the elaboration of a architectural stdy in early design stages, enabling the application of computer softwares tools in accordance with their specific attributes. It proposes a methodology to architectural creation combined with photovoltaic energy generation, addressing aspects of performance, costs and environmental benefits by computer simulations in available and easily accessible softwares. Five tools were selected: SketchUp, System Advisor Model, Corel Photo-Paint, Microsoft Excel and BIPV Design. The tools were applied and three different model surfaces were selected by their radiance potencial, called active surfaces, planes which were forecast for installation of PV panels. A table summary of the data collected by the toosl is displayed. The results demonstrated the feasibility of the method as well as the tools, used as a support in the early stages of design SFVIA, mainly in the technical aspects of power and energy generation estimates, needed area for instalation ,appearance of photovoltaic modules, and architectural reference works . The yield or productivity index was used as a qualitative assessment factor of the system. Productivity rates (yield) demonstrated that the proposed system would produce 65.62% compared to the yield of a reference system (SR). Were identified, however, limitations on the environmental and economic data provided by the tools, considered insufficient to obtain a holistic overview of the possible benefits of BIPV systems, and of the investments feedbacks of energy systems of this type. At the end it is suggested to validate the method proposed by other studies and compared with data from other tools.
