Abstract
In the present study, a sensitivity analysis was carried out in order to evaluate the performance of the Solar Energy on Building Envelopes (SEBE) model to different meteorological input data. The model was applied on a sixmonths period from July to December 2018. Geostationary satellite data provided by Meteosat MSG was first validated against measurements from permanent weather stations located both in the urban area of Bolzano and in the surrounding countryside. Subsequently, several SEBE simulations were performed in order to compare the outcomes obtained from satellite data against simulations fed by meteo-radiometric measurements. The validation of satellite data shows that global shortwave irradiance data provided by the Meteosat are representative of the solar radiation fluxes, even in a complex terrain. SEBE simulations fed by different meteorological input performed well at different comparison locations although showing slightly broad errors using satellite data as input.
