Decarbonising buildings and energy districts for the benefit of all: how cities can drive the change

How can cities turn ambition into action on decarbonised buildings and districts?

As a city, where do you start to become climate-neutral? Home renovation is a good place to begin, as residential buildings are among the most energy-intensive sectors, with space heating alone accounting for over 60% of household energy consumption in the European Union.

How can home renovation be sustainable while ensuring people live in healthy, comfortable, and energy-efficient homes? And how can you decarbonise the energy system by actively engaging citizens and stakeholders?

Vilnius is showing the way. During the 2-day SPARKLE School, you will explore the twin challenges of building renovation and district decarbonisation. You will learn from European experts, exchange ideas with municipal peers, engage in hands-on workshops, and visit pioneering Vilnius projects, including large-scale renovation schemes and renewable-powered heating and cooling systems.

This is not just a training: it’s a space to connect with peers, test new ideas, and take home practical tools that can turn ambition into action. By seeing real projects in practice and learning from Europe-wide best practices, you will strengthen your ability to shape healthier, more resilient communities.

Are you ready to spark the transition to decarbonised buildings and districts? Join us in Vilnius!
