Everything in Flow: Natural Oasis and “Sponge City Roof” Roof Greening of St. Jakobshalle

With various design variants and seeds from the Reinacher Heide, a nature-like riverbank landscape was created on the roof of the St. Jakobshalle – a paradise for insects and birds, on a roof! The “Sponge City Roof” is hydrologically connected to a secondary roof and optimizes water retention.

Unmistakable, Distinctive, and Yet Delicately Built and Greened – Futuro Liestal

The design idea for the building greening on the Futuro building developed from an interpretation of the surrounding cultural landscape with principles of Concrete Art. The cultural landscape of Northwestern Switzerland, especially the Basel-Landschaft Jura, is a small-scale mosaic of different agricultural and horticultural uses and plant cultures. The areas immediately adjacent to the Futuro site also follow this pattern. This form is therefore adapted for the design of the roof, particularly. A large-scale, ground-bound facade greening surrounds the distinctive, delicate building.

Uptown Basel, Roof Greening

Uptown Basel is an international competence center for Industry 4.0. On the historically significant 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 characteristics.

Exhibition Hall 1 by Theo Hotz, Roof Greening with PV System

Exhibition Hall 1 is a building by the renowned Swiss architect Theo Hotz. The building is 210 meters long, 90 meters deep, and 20 meters high and was completed in 1999. The roof areas, covering approximately 16,000 m², are extensively greened and equipped with photovoltaic systems at the edges. With a total panel area of 1,850 m², the roof was the largest such installation (roof greening and photovoltaics) in Switzerland at the time of construction. It produces 215,000 kWh of electricity per year. The solar system cost 2.3 million Swiss francs.

Exhibition Hall by Herzog & De Meuron, Roof Greening with PV System

The roof greening on the latest new exhibition hall by Herzog & de Meuron was retrofitted with a photovoltaic system after its construction and is now one of the largest such systems on roofs in Basel. In 2024, an additional ecological upgrade was carried out by the Roof Greening Association of the Basel Region.

And It Smells Good! Facade Greening “Wisteria Alley” Feldbergstrasse

An “icon” of ecological upgrading of street spaces, where over 60 wisterias have been greening, cooling, and enriching Feldbergstrasse for 30 years. What should be considered for successful facade greening, and how can entire streets be best upgraded with climbing plants?
