Athens is changing. As the climate crisis brings relentless heatwaves and sudden heavy rains, cities built for yesterday’s climate struggle to protect their people today. Streets heat up, infrastructure floods, and residents feel the pressures of an urban environment that desperately needs more nature.
In this reality, Impact Hub Athens is proud to be part of Cooling Havens, an innovative project led by the Municipality of Athens and co-funded by the European Urban Initiative – Innovative Actions (EUI-IA).
What are Cooling Havens?
Cooling Havens are neighbourhood-scale, water-powered public spaces that use nature-based solutions to bring cooler, healthier, and more resilient environments into the dense urban fabric of Athens.
Each intervention combines infrastructure, ecology, and community life through:
- Rainwater harvesting gardens and bioswale wetlands to capture and filter stormwater.
- Water-sensitive design to reduce urban heat and ease the heat-island effect.
- Community spaces that connect water to everyday life, history, and culture.
Seven neighbourhoods will soon host Cooling Havens: Ilisia, Metaxourgio, Kolonos, Exarhia, Probonas, Ambelokipi, and Kipseli.
Why it matters
Cooling Havens are more than infrastructure projects. They represent a new way of shaping cities:
- They fight extreme heat with natural cooling and shaded spaces.
- They address urban flooding by absorbing rainwater instead of letting it overwhelm drainage systems.
- They build social resilience, turning public spaces into places of learning, engagement, and shared ownership.
Impact Hub Athens’ role
At Impact Hub Athens, our focus is on community engagement and activation. For us, resilience is not just about physical infrastructure but also about people.
Starting in September 2025, we will host participatory workshops in each neighbourhood. These sessions will:
- Bring residents together with architects and engineers to co-design the Cooling Havens.
- Identify local needs and concerns to ensure inclusivity.
- Strengthen community ownership so that Cooling Havens become long-term neighbourhood assets.
This approach ensures that the project is not only technically sound but also socially meaningful.
Looking beyond Athens
The impact of Cooling Havens will extend beyond Greece. Partners in Budapest (Hungary), Roeselare (Belgium), and Sofia (Bulgaria) will adapt the project’s innovative elements, spreading knowledge and amplifying resilience across Europe.
Looking ahead
The first project phase, site visits, design studies, and location evaluations is complete. The next steps will turn concepts into reality: detailed designs, engineering studies, and eventually, construction.
By 2028, Athens will host seven fully functional Cooling Havens, each a small but powerful step toward a cooler, greener, and more resilient city.
For us at Impact Hub Athens, this project is about showing how nature, innovation, and community can come together to reshape urban life.
