| description |
The demand for energy in buildings is a worldwide research subject due to its importance in the global electric load share. Besides, photovoltaic conversion to generate electricity locally is one of the ways to meet that demand. This work aims to evaluate the application of semi-transparent photovoltaic glass on a skylight of a commercial building and estimate electricity consumption and production using computational simulation with EnergyPlus. The opening size was set as a variable parameter. Its performance was compared to an ordinary skylight and opaque modules under the same conditions for three different Brazilian bioclimatic zones. Results show that the area's change provided significant differences in generation and less important ones in consumption. Among the bioclimatic zones, the building presented the lowest consumption and the highest generation for all configurations in the coldest zone, making it the best region for net electricity, i.e., purchased from a utility. Comparing semi-transparent with opaque modules, the latter produced much more energy, but consumption was reduced by an average of 28% in favour of the photovoltaic glass. The main conclusion is that the use of photovoltaic technology in a semi-transparent glass is promising regarding the integration of generators to the building, but the efficiency rates need to increase to bring it closer to opaque modules in performance. |

A demanda por energia em edifícios é um tema de pesquisa mundial, devido ao seu peso relativo no total da carga elétrica. Além disso, o uso da conversão fotovoltaica para gerar eletricidade no próprio local de consumo é uma das maneiras de atender a essa demanda. Este trabalho tem como objetivo avaliar a aplicação de vidro fotovoltaico semitransparente em abertura zenital de um edifício comercial e estimar o consumo e a produção de eletricidade usando simulação computacional com o EnergyPlus. O tamanho da abertura foi modificado e seu desempenho foi comparado com uma abertura comum e o uso de módulos opacos nas mesmas condições, em três diferentes zonas bioclimáticas brasileiras. Os resultados mostram que a mudança na área proporcionou diferenças significativas na geração e menos importantes no consumo. Dentre as zonas bioclimáticas, na mais fria o edifício apresentou o menor consumo e a maior geração para todas as configurações, tornando-a a melhor região para atendimento a uma meta de eletricidade líquida, ou seja, adquirida da rede pública. Comparando módulos semitransparentes com opacos, estes últimos produziram mais energia, mas o consumo foi reduzido em média 28%, com vantagem para o vidro fotovoltaico. Conclui-se que o uso da tecnologia fotovoltaica em vidro semitransparente é promissor para a integração de geradores ao edifício, mas precisa aumentar o rendimento para se aproximar dos módulos opacos no desempenho.
