Time2Adapt - Time-based Innovative Measures and Experimentations to ADAPT our cities to climate change

New European Bauhaus demonstrators


How to ensure EU cities remain liveable as climate change pushes temperatures to new highs? Time2Adapt proposes an integrated, time-based approach that makes the most of the versatility and modularity of existing urban spaces and installations. The solution involves limiting land artificialisation and improving access to comfortable places for citizens, especially the most fragile, during hot summers. Actions range from adjusting opening times, or developing new uses, to temporarily occupying public space with refreshing artistic installations. The project also explores innovative, integrated approaches to managing these places.

Our main challenges...

  • Respond to increasing vulnerabilities linked to climate change (urban heat island effect, droughts, heatwaves).

  • Support structural and cultural changes and the innovative management of public places, including new working practices (co-construction, mutualisation, partnerships, collaborations).

  • Prepare public actors and inhabitants for climate change and make Lille Metropole a resilient territory.

and proposed solutions

  • Reinforcing the provision of cool and safe places using a time-based approach, intensifying existing use, transforming places, and providing temporary outdoor facilities and furniture in public places.

  • Allowing the population to take ownership of cool places. T2A encourages involvement of inhabitants and public services in a design process based on dialogue, co-conception and evaluation.

  • Testing a range of new management methods for public facilities. Increasing access to cool places has consequences for staff working practices and organisation.
