ZHAW Switzerland (Dr Stephan Brenneisen, Wädenswil) provided their long-term knowledge about green roof technology and asked us to carry out the task for the artistic/visual concept. The green roof should not only provide a visual amenity but will also enhance biodiversity as well as ameliorating water run-off.
This feature will consist of a lightweight, semi-extensive green roof, where low growing drought resistant plant species, such as stonecrop, will be planted. These species need very little maintenance or water and can survive well in harsh environments. Watering is only required within the first few weeks after installation and during severe drought.
