From vertical solar systems and black earth
Can solar systems be combined with green roofs? When do vertical solar systems make sense? How big is the contribution of biochar and soil formation to the climate crisis? We will be discussing these and other questions today from 4 - 5 pm in an online chat with three pioneers who have experimented with these combinations.
Andreas Dreisiebner, the horticulturalist who became a solar pioneer According to Dreisiebner, the generation of green energy using photovoltaics, biomass, small wind turbines and hydropower can be perfectly combined with walls on buildings and surfaces in the city as well as various plants. A system that he implemented with Solarspar on the roofs of Valser / Coca Cola at 1,200 meters above sea level demonstrates the advantages of vertical systems, which are particularly effective in the Alps: The snow slides down and reflects back some of the sunlight. This means that the slanting winter sun can also be used to cover the winter electricity shortfall.

Fredy Abächerli, the pioneer in soil building and biochar | Bionika stands for over 60 years of experience and research into regenerative agriculture and healthy food. The company offers intelligent strategies for the sustainable improvement of soil fertility through permanent, climate-relevant humus build-up, as well as efficient water and nature conservation and successful regeneration of biodiversity, which has been dwindling for years. Mr. Abächerli advises farmers and is one of the first companies in Switzerland to offer biochar in various combinations with humus as a product.

Martin Jucker, the farmer who turned the Jucker Farm into a place of adventure with an innovative energy concept At the Jucker Farm in Rafz, it's not just the asparagus that is green. The energy concept is also exemplary in terms of sustainability. Designed as an island solution, it could even supply the farm with energy energy independently of the public power grid. A large PV system generated electricity, heat and cooling, which, together with a local storage system, form a self-sufficient overall system.
