Energetic optimization of the existing building, moss garden
For better thermal insulation of the lightweight concrete masonry the existing building was equipped with a back-ventilated curtain facade. Similar to the plumage of a bird the slate façade as external skin protects from water and the cold, on the other hand it serves as camouflage and as means of visual communication.
The local conditions like, for example, a sandy, nutrient-poor and acidic soil make it possible to create a moss garden, which can also survive under snowfields. Where normal flowering plants cannot grow cotton gras, saxifrage, lycopod, cranberries, sundew, bell heather and moor orchids can thrive.
