a2-solar designs solar modules for one of Europe's largest solar glass facades

With a surface of approximately 13.000m², the energetically optimised facade has been designed by the renowned architects of Ingenhoven Architekten and carried out in close cooperation with the metal construction company HW Würfel Metallbau and a2-solar.

The façade consists of metal frames aligned towards the sun, for which the solar modules have been specifically customized by a2-solar.

The overall output of 220kWp is generated by a total of 880 solar modules, which a2-solar has manufactured as special seamless double-glass modules with the exceptional dimensions of 3.5m height on 60cm width, weighing almost 100kg each.

The 7mm spacing between the solar cells creates a high transparency for the wood panels installed behind: a design concept elaborated by the Ingenhoven architects to combine highest art of technology with natural building materials.

For a2-solar, this project forms again another great success to realize an extra-ordinary synthesis of design and functionality.

Thanks to this innovative solar façade, this new municipal building fulfils all of the EnEV requirements as one of the first public buildings. Thus, this City Hall completely matches with the principal standards of a zero-energy building.

The “green building” concept with a 100% energy self-sufficiency, however, was only successfully achieved by using the façade surface in addition to the photovoltaic roof-top system.

Also, the Fraunhofer Institut für Solare Energiesysteme (ISE) validates this project for its holistic characteristics of sustainability and integrity.

Due to the ENEV regulations, all buildings and facades are to be equipped with energy-saving components in the future. a2-solar has specialised in how to meet these requirements.
