Valutazioni delle prestazioni energetiche di sistemi BiPV: un caso di studio numerico sperimentale = Energy performance assessment of BiPV façades: a numerical and experimental case study

Aim of this numerical and experimental study, is to show the main critical points in the design of building integrated photovoltaic systems (BiPV) in ventilated façades. This study focused its attention on an eight-storey residential building located in Chiasso (Ticino, Switzerland), which was characterized on elevation by the use of façade BiPV. The work is focused on optimizing the energy output of the PV system and the analysis of the relative effects due to the indoor thermal comfort. The efficiency of the BiPV façade was calculated using the software PVsyst, after validation of an experimental model installed at ISAAC (CH), with particular focus to the effects of partial shading of the panels. In the second phase of the study, we analyzed the configuration of the ventilated façade and efficiency in terms of controlling the temperature of the inside surface of the building envelope and PV panels, using energy analysis in dynamic conditions shaped with the software Energy Plus. In order to increase the problems of overheating, the analysis was carried out with reference to the climatic context of the city of Bari (IT, 41°07'31'' N, 16°52'00'' E, 5 m a.s.l.).
