How can existing rooftops help make cities cooler, greener and more liveable? On this family tour, you will discover the rooftop garden of the HIL building as an open-air living laboratory and learn how innovative solutions can help cities adapt to climate change.

You will see how rooftops can store rainwater, release it more slowly, allow it to infiltrate and cool the surrounding area through evaporation. Discover how ordinary roofs can become climate-active spaces that promote biodiversity, improve the local microclimate and create new places for people above the city.

Together, we will explore why these solutions are becoming increasingly important in the face of heatwaves, droughts and heavy rainfall. Look forward to fascinating insights and discover rooftops from a completely new perspective – not just as technical structures, but as hidden water landscapes with great potential for people, cities and the environment.
