The project aims at applying the 50/50 methodology to 50 educational centers in order to contribute to the fight against climate change. Within the frameworks of the project an European network of schools will be created and energy efficiency measures will be implemented in chosen school buildings. The 50/50 concept assumes that thanks to taken up actions 2,5% energy savings will be achieved and money saved will be divided between schools (50%) and municipalities (50%).The result is that everybody wins: schools improve their energy efficiency and sanitary conditions, local authorities pay less for energy and the society gets the cleaner environment. Schools have been chosen to take part in the project as they are a perfect place to promote energy sustainability, ensuring that future generations consume energy responsibly and influence their families to do the same. 9 partners from 9 countries participate in the project.
