Natural Oasis in the Air – Roof Greening at Jacob Burckhardt House, Basel
High above the train tracks, a natural oasis with orchids and a great variety of plants opens up. We show how simple design tools can promote biodiversity on roofs.

Facade and Roof Greening in Gundeldingerfeld – A Variety of Green Artworks! – with the Addition of a Wall Greening
An intoxicating area with countless niches and plant artworks, new ideas for the green and climate-adapted city of the future. Sponge city roof greening, which is watered with brewery wastewater, and a fantastic green wall round off the plant fireworks!




11:15
Diversity on the Roof – Roof Greening at the University Hospital Basel
A model roof greening with diverse microhabitats lies in front of the bed house of Clinic 2 and lets patients look into the green. We show the ecological diversity of insects, beetles, and grasshoppers that have found a new home here. With luck, we might even see a wonderful blooming orchid, the bee orchid.

Almost “…above the clouds”: Roof Greening High Above Basel – Natural Oasis at the Biozentrum, Basel
High above Basel, a model roof greening for the future was created. We show here how natural oases on roofs can survive future dry periods and mitigate the overheated urban climate.



14:45
Green Buvette on the Rhine
A shipping container was converted and equipped with a roof greening for the production of various herbs used in the bar & cafe built into the container. A culinary delight and a symbol of circular production on site.

Production of substrate mixtures for green roofs – visiting a mixing plant
In Village-Neuf (Port Huningue), bulk materials imported via ship are processed into substrate mixtures at the Sassi company for green roofing and other uses. We demonstrate the process, equipment, and materials that are processed into various specific mixtures.
