With its rectangular layout and pitched roof, House Schneller Bader provides a perspective backdrop to a farmyard on one side and an open field on the other. The single-family home is impressive due to the perfect integration of the photovoltaic system on the southern-facing side of the roof.

The building's bearing structure is reinforced concrete; an insulating layer and an interior brick wall complete the vertical envelope. The ventilated roof consists of a wooden frame structure that rests directly on the load-bearing masonry. The pitched roof design includes photovoltaic modules and fibre cement panels. The building as a whole is reminiscent of traditional buildings in the area. Due to these unique characteristics, the project won the Norman Foster Solar Award in 2017.

Thanks to the choice of materials and colours and the careful alignment, this new building fits perfectly into the surrounding landscape. The photovoltaic modules completely cover the southern side of the building's roof. The dark colouring similar to that of the fibre cement panels on the other side and the appropriate arrangement of the modules makes this building an excellent example for integrating BIPV systems into traditional architecture.

The BIPV modules generate 22800 kWh of electricity per year, completely covering the building's cumulative demand. Almost 44% of the electricity produced is sent to the network.

The monocrystalline silicon photovoltaic modules are integrated in the roof's ventilated package and cover the entire surface.
