Simulation of a photovoltaic hybrid facade

The conception of complex buildings with innovative facade elements often demands dynamic building simulations. In some cases the required thermal parameters of the components must be obtained by experimental investigations. This paper describes this procedure exemplary for a photovoltaic facade, which allows the combined utilization of electrical and thermal energy. The parameters for a TRNSYS simulation could be obtained with the help of a PASSYS testcell. The results show that the total energy transmittance (gvalue) of such a facade strongly depends on the ambient air temperature.
