Evaluation of the daylighting potential of OPV windows for deep-plan rooms

Generally, multi-storey office buildings count with large glazing surfaces that allow users to enjoy daylighting and natural ventilation and, in addition, provide visual contact with the outdoor environment. However, without an appropriate treatment, these surfaces could influence the buildings ther...

description Generally, multi-storey office buildings count with large glazing surfaces that allow users to enjoy daylighting and natural ventilation and, in addition, provide visual contact with the outdoor environment. However, without an appropriate treatment, these surfaces could influence the buildings thermal loads, and moreover, cause glare in workers. Therefore, a photovoltaic window could be used not only to optimize daylight distribution but to provide energy to artificial lighting when necessary. This research aims to evaluate Organic Photovoltaic (OPV) application in side windows of multi-storey and deep plan office buildings to verify its contribution to the daylight quality of the internal environment. The evaluation was performed in a small-scale model of a generic office room, illuminated by a side window, corresponding to 100% of the North façade. Three window material types were compared under real sky condition in Curitiba-PR: scenario A – 3 mm single glass; scenario B – glass and OPV; and, scenario C – glass with solar film. Besides the reduction in illuminance resulting from scenarios B and C in relation to scenario A, a better daylighting distribution was noticed inside the room and, in addition, in scenario B there is also the possibility of using photovoltaic energy for artificial lighting.

Edifícios de escritório com múltiplos pavimentos, em sua maioria, possuem grandes superfícies envidraçadas que possibilitam aos usuários usufruir de luz e ventilação natural, além do contato do observador com o meio externo. Entretanto, sem um devido tratamento, essas superfícies podem possibilitar aumento/redução de carga térmica para o edifício, assim como causar ofuscamento nos trabalhadores. Neste sentido, a janela fotovoltaica poderia ser utilizada tanto para melhorar a distribuição da iluminação natural quanto para suplementar energia para iluminação artificial quando necessária. O objetivo dessa pesquisa é avaliar o potencial da aplicação de Dispositivos Orgânicos Fotovoltaicos (OPV) em janelas laterais de edifícios de escritórios com múltiplos pavimentos e salas profundas, a fim de verificar a sua contribuição em relação à qualidade da iluminação natural no ambiente interno. Realizou-se a avaliação por meio de um experimento com um modelo em escala reduzida de uma sala de escritório genérica, iluminada por uma janela lateral, a qual corresponde a 100% da área da fachada Norte. Compararam-se três tipos de materiais para a janela sob condição de céu real em Curitiba-PR: Cenário A - vidro simples 3 mm; Cenário B – vidro e OPV; e, Cenário C – vidro com aplicação de película solar. Apesar da redução da iluminância com a utilização dos materiais dos cenários B e C em relação ao material do cenário A, constatou-se uma melhor distribuição da iluminação natural no interior da sala, sendo que no cenário B existe a possibilidade de utilizar a energia gerada na janela fotovoltaica para a iluminação artificial.
