The Gundeldingerfeld is a former industrial site that has undergone a sustainable transformation. The site is located in the residential and commercial district of Gundeldingen, which lies within walking distance from Basel’s main train station. A variety of Gundeldingerfeld's features were displayed during the tour, including:

• The integration of the existing structures
• Repurposing of the site for different uses (office space, kitchens, recreational spaces)
• Social networking
• A colourful solar facade with "Second Life" storage in a former coal silo (a project as part of the "2000-Watt Society - Pilot Region Basel"; the project is accompanied by a study from the University of Applied Sciences and Arts Northwestern Switzerland)

Tour 1: The Sustainable Model District of Vauban

Find out about the urban development of this highly ecological district. A former military base that was redeveloped into a new district for 5.000 inhabitants in the 1990s, Vauban is an internationally known model of sustainable urban planning. During this study tour participants learned more about renewable energy, citizen engagement and energy efficient building design.

Tour 2: Fraunhofer Institute for Solar Energy Systems

The Fraunhofer Institute for Solar Energy Systems ISE is the largest research institute for renewable energies in Europe. Participants learned about the innovative technologies behind the Energiewende ("Energy transition"), such as photovoltaics, solar thermal energy, energy-efficient building technology, smart grids, electric mobility, energy storage and smart cities.

Tour 3: Badenova

Using a combination of heat pumps, hydroelectric generators and wood pellet heating, Badenova WÄRMEPLUS - a subsidiary of Badenova - has developed an innovative and efficient solution for heating and cooling for over 100 apartments and office space. A key aspect of the concept is integrating an existing pond, which can be used both for heating (via a heat pump) and climate-friendly cooling during the summer months.
