Fraunhofer Institute for Solar Energy Systems ISEA Plus-Energy Building certificate was awarded within the framework of the Swiss Solar Prize for the renovation of an apartment building in Zurich, where a challenging example of building-integrated photovoltaics (BIPV) was designed with support from Fraunhofer ISE. By integrating photovoltaics into the roof and facade surfaces, a Plus-Energy standard was achieved, while preserving the Art Nouveau architecture. Simulation models of Fraunhofer ISE were used for the detailed system design with respect to yield and operational safety. These models consider partial shading, different module orientations and module sizes using a 3D model. The renovation was completed in April 2015 and the BIPV contributes with its yields significantly to achieving the Plus-Energy standard, as predicted. | Duration: 2015 - April 2016

Prototype of an evacuated glazing unit with 0.5 mm spacers at 3 cm intervals. The spacers can hardly be seen. The total thickness of the glazing unit is 9 mm (the frame thickness is app. 20 mm) and its weight is comparable to that of a standard double-glazed unit. Windows with an area of 1 m x 1 m are currently being developed by Fraunhofer ISE.
