The building in Gronau was already occupied at the end of 2022. Transparent glass modules now produce solar power: while the glass modules allow light into the building from outside, they offer a feeling of enclosure despite their transparency - and with a full view. The electricity is produced by organic solar cells (OPV), which ASCA applies to films using a special printing process.

The glass facade at the administration building in Gronau covers an area of 222 square metres and provides almost ten kilowatts of output. "The shop window facing the street visualises the themes of energy and sustainability," the architects H III S from Stuttgart explain the design. For this purpose, the glass modules with integrated ASCA solar film measuring 3.66 by 2.25 metres were attached to the south facade of the new building, alternating with conventional glass panes.

For the project in Gronau, ASCA produced green foils in line with the surrounding brick facade of the adjacent buildings. "The variety of design options convinced us," say the architects. The production of the modules, they say, is no more complicated than the manufacture of normal laminated glass. "This represents a milestone for the building integration of photovoltaics, or BIPV for short," explains Hermann Issa. She is head of Business Development & Project Management at ASCA. (nhp/mfo)
