The buildings sector requires more than 40% from the total energy consumptionin Europe. In order to obtain the European energetic goals of decreasing the fossil fuel dependency by 2020 and beyond to 2050, new and efficient strategies concerning renewable energy should be integrated in buildings. In this study a comparative dynamic numerical analysis of the cooling energy performance of a facade building integrated with semitransparent PV cells inside the facade cavity is presented. The comparison included three main items, facade cavity ventilation system, facade inner layer glazed composition and three different climatic conditions. An Optimization between hybrid and natural ventilation system for the cavity is clarified. Putting forward an innovative idea to cool the cavity from indoor air to increase the conversion efficiency of PV modules installed inside the cavity. The energy analysis has-been carried out by TRNSYS and the validation of the numerical model has been elucidated. (C) 2015 Elsevier B.V. All rights reserved.
