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.
