W-ROB
Transdisciplinary project “W-rob” started
The core team, consisting of Cathrin Zengerling, Melissa Siegl and Clara Brühl from the “Law” department and other colleagues from the fields of politics/governance and geography/infrastructure, has been working on the challenges of heat planning for half a year now. The focus is on the task of identifying the central challenges and developing solutions in cooperation with the practical partners, including local government representatives from eight cities. This raises the question of how heat planning can be achieved in the most “socially robust” way possible, i.e. in particular with a high degree of transparency, broad acceptance among the population and voluntary, active implementation.
