8:45
Urbaner Dschungel über den Dächern – Biodiversität und Erholung auf einem Basler Wohnhaus
Ein dicht bewachsener Dachgarten, der seit über 20 Jahren gedeiht – lebendig, vielfältig und voller Leben. Hier oben trotzt das Grün allen Vorurteilen über Dachbegrünungen: üppig bepflanzt, ökologisch wertvoll und in perfektem Zusammenspiel mit den Sonnenkollektoren an der Fassade. Gemeinsam erkunden wir diesen privaten Rückzugsort über der Stadt, sprechen über urbane Biodiversität, Lebensqualität und die Rolle von Gebäuden als multifunktionale Lebensräume.


9:45
Green Wall, Parking Garage West, Allschwil
A 19-meter-high green wall is located on the north side of the parking garage in Allschwil. Around 2,200 plants are located on an area of 28 m².


10:30
Everything in Flow: Natural Oasis and “Sponge City Roof” Roof Greening at St. Jakobshalle
With various setup options and seeds from Reinacher Heide, a natural riverside landscape was created on the roof of St. Jakobshalle – a paradise for insects and birds, on a roof! The “Sponge City Roof” is connected to an adjacent roof for drainage purposes, optimizing water storage.





11:30
Uptown Basel
Uptown Basel is an international competence center for Industry 4.0. On the historic Schoren site in Arlesheim near Basel, a development and production site is being created where selected technology companies and other organizations are settling. The intensive roof greening is part of the concept for closed resource cycles in an area with ecological pioneer character.

Lunchbreak
13:15
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.



14:15
A Superlative Facade Greening at the Stücki Park Shopping Center
Two large-scale facade greenings with different features were realized here: Plant troughs placed per floor harmonize as an entire green area. The various plant species climb on wire ropes and shape the facade image. The other solution on the back of the building impresses with x-shaped tensioned wire ropes, from the ground via steel stairs to the roof edge. An additional, suspended and natural facade is created. Architects: Diener & Diener, Basel



15:15
And it smells good!
Facade Greening “Wisteria Alley” Feldbergstrasse An “icon” and a milestone in the ecological enhancement of street spaces, over 60 wisterias have been greening, cooling, and enriching Feldbergstrasse for 30 years. What should be considered for successful facade greenings, how can we best enhance entire streets with climbing plants?


15:30
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.




16:45
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.
