The Erni family’s detached house in Thun, built in 1953 in the style of a chalet, was renovated in 2020, preserving the original structure of the building. Its energy performance was improved in order to obtain Swiss Plus-Energy building certification. Thanks to the improvement in energy efficiency of the building envelope and the use of energy-saving appliances, the total energy requirements of the building have been reduced by 85%, from 48,500 kWh/year to 7,500 kWh/year. Both sections of the roof are covered with integrated photovoltaic modules.

The BIPV modules are distributed over the two sections of the roof, covering all of the available space and creating a dark, even surface.

The BIPV system produces approximately 17,900 kWh per year, guaranteeing an energy supply that covers 238 % of the home’s requirements.
