Green Roof Systems Adopted Across Austria and Switzerland

BauderGREEN intensively roof‑garden systems provide modular planting solutions for flat roofs, offering options for perennials, shrubs and trees. The systems are rated for loads of about 539 kg/m² (perennials), 854 kg/m² (shrubs) and 1,414 kg/m² (trees) and can be installed on roofs without special water‑retention or structural requirements.

In Switzerland, roof surfaces are being transformed into multifunctional spaces that combine vegetation for biodiversity, rain‑water storage, insulation and air‑quality benefits with photovoltaic panels to meet the 2050 energy strategy. Combining green roofs with solar requires precise coordination to avoid shading, protect roof membranes and match the service life of both systems. Compliance with standards such as SIA 271 and SIA 2062, appropriate material selection and early involvement of roofers, solar installers and gardeners are highlighted as essential for long‑term success.
