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

Building renovation should be a top priority for municipalities, as this is one of the most energy-intensive sectors, with space heating alone accounting for over 60% of household energy consumption in the EU. But how can energy systems be decarbonised while actively engaging citizens and stakeholders?

Over two inspiring days, you will explore the twin challenges of large-scale renovation and district decarbonisation. You will learn from leading European experts, exchange experiences with municipal peers, take part in hands-on workshops, and visit pioneering projects across Vilnius, including major renovation programmes and renewable-powered heating and cooling systems.
